There are important capabilities for the systems analyst to master which are called project
management fundamentals. This includes the initiating of projects, determining feasibility,
scheduling projects, and planning and then managing activities and team members for production.
There are two broad reasons why business people suggest systems projects.
Problems in the Organization
Problems surface in many different ways. One way of conceptualizing what problems are and
how they arise is to think of them as situations in which goals have never been met or no longer
being met. Useful feedback gives information about the gap between the actual and intended
performance. In this way feedback spotlights problems.
Checking output, observing employee behavior, and listening to feedback are all ways to help the
analyst pinpoint systems problems and opportunities.
Defining the Problem
To identify problems:
Check output against performance criteria
Observe behavior of employees
Listen to external feedback from: VENDORS;
CUSTOMERS; SUPPLIERS
Look for these specific signs:
Too many errors
Work completed slowly
Work done incorrectly
Work done incompletely
Work not done at all
High absenteeism
High job dissatisfaction
High job turnover
Complaints
Suggestions for improvement
Loss of sales
Lower Sales

Whether using the classical SDLC or an object-oriented approach, the analyst first defines the
problems and objectives of the system. These are the components of a problem definition:
In problem statement, it should be summarized into one or two paragraphs. The issues are the
current situation, while the objectives are the desired situation. The requirements contain the things
that must be accomplished and may include security, usability, government requirements and so on.
And lastly the constraints, that limit the development of the system.
The problem definition is produced after completing interviews, observations and document
analysis with the users. Major points can be identified in the interview in a number of ways.
There are things that a system analyst must remember in regards with issues and objectives:
The relative importance of the issues and objectives must be determined. The identification of the most critical objectives is best done by users. Assign a weight for each issue and objective. The problem definition issues and objectives are rearranged in order of decreasing importance.A Problem Definition Example: Catherines Catering

Selection of Projects
You must be clear in your own mind about the reasons for recommending a systems
study on a project that seems to address a problem or could bring about improvement. There are
five specific criteria for project selection:

Organizational goals
Possibilities of improvements
II. Determining FeasibilityOur definition of feasibility goes much deeper than the usual usage of the term, because systems project
feasibility is succeeded in three ways: operationally, technically and economically. The feasibility study is not a
full-blown systems study. Rather, the feasibility study is used to gather broad data for the members of
management that in turn enables them to make a decision on whether to proceed with a systems study.
Data for the feasibility study can be gathered through interviews. The kind of interview required is
directly related to the problem or opportunity being suggested. The systems analyst typically interviews thoserequesting help and those directly concerned with the decision-making process, typically management.
Although it is important to address the correct problem, the systems analyst should not spend too much time
doing feasibility studies, because many projects will be requested and only a few can or should be executed.
The feasibility study must be highly-time compressed, encompassing several activities in a short span of time.
Determining whether it is Possible
After an analyst determines reasonable objectives for a project, the analyst need to determine if it is
possible for the organization and its members to see the project through completion. Generally, the process of
1. Improving corporate profits.
2. Supporting the competitive strategy of the organization.
3. Improving cooperation with vendors and partners.
4. Improving internal operations.
5. Improving internal decisions.
6. Improving customer service.
7. Increasing employee morale.

feasibility assessment is effective in screening out projects that are inconsistent with the businesss objectives,
technically impossible, or economically without merit.
Although its painstaking, studying feasibility is worthwhile because it saves businesses and systems
analysts time and money. In order for an analyst to recommend further development, a project must be feasible
in all three of the following ways: technically, economically, and operationally.
TECHNICAL FEASIBILITYThe analyst must find out whether it is possible to develop the new system given the current technical resources
If not, can the system be upgraded or added into a manner that fulfills the request under consideration? If
existing systems cannot be added onto or upgraded, the next question becomes whether there is technology in
existence that meets specifications.
At the same time, the analyst can ask whether the organization has the staff who are technically proficient
enough to accomplish the objectives. If not, the question becomes whether they can hire additional
programmers, testers, experts, or others who may have different programming skills from theirs, or maybe
outsource the project completely. Still another question is whether there are software packages available that
can accomplish their objectives, or does the software need to be customized for the organization?
ECONOMIC FEASIBILITYThe basic resources to consider are your time and that of the systems analysis team, the cost of doing the full
systems study, the cost of the business employee time, the estimated cost of hardware, and the estimated cost of
software or software development.
The concerned business must be able to see the value of investment it is pondering before committing to an
entire systems study. If short-term costs are not overshadowed by long-term gains or produce no immediate
reduction in operating costs, the system is not economically feasible and the project should not proceed any
further.
OPERATIONAL FEASIBILITYOperational feasibility is dependent on o the human resources available for the project and involves projecting
whether the system will operate and be used once it is installed.

If users are virtually wed to present system, see no problems with it, and generally are not involved in
requesting a new system, resistance to implement a new system will be strong. Chances for it ever becoming
operational are low.
III. Ascertaining Hardware and Software NeedsAssessing technical feasibility includes evaluating the ability of computer hardware and software to
handle workloads adequately. First, all current computer hardware the organization owns must be inventoried todiscover what is on hand and what is usable. Knowledge of the organizational structure and how users interact
with technologies in an organizational setting can also be helpful in hardware decisions. Only when system
analysts, users, and management have a good grasp of what kinds of tasks must be accomplished can hardware
options be considered.
Inventorying Computer Hardware
Begin by inventorying what computer hardware is already available in the organization. As will become
apparent, some of the hardware options involve expanding or recycling current hardware so it is important to
know what is on hand.
If an updated computer hardware inventory is unavailable, the systems analyst needs to set up one
quickly and carry through it. You need to know the following:
A. Type of Equipment: model, number, manufacturerB. Operation Status: on order, operating, storage, in need of repairC. Estimated age of equipmentD. Projected life of equipmentE. Physical location of equipmentF. Person responsible for equipment
-
7/22/2019 SAD Written Report
9/27
G. Financial arrangementESTIMATING WORKLOADS
The next step in ascertaining hardware needs is to estimate workloads. Thus, system analysts formulate
numbers that represent both current and projected workloads for the system so that any hardware obtained will
possess the capability to handle current and future workloads.
If estimates are accomplished properly, the business should not have to replace hardware solely due tounforeseen growth in system use. Out of necessity, workloads are sampled rather than actually put through
several computer systems.
COMPARISON OF TIMES REQUIRED BY EXISTING AND PROPOSED INFORMATION
EVALUATING COMPUTER HARDWARE
Although vendor will be supplying details about their particular offerings, analysts need to see the
evaluation process personally because they have the best interests of the business at heart. In addition, system
analysts may have to educate users and management about the general advantages and disadvantages of
hardware before they can capably evaluate it.
In addition, workloads can be simulated and run on different systems, including those already used in anorganization. This process is referred to as benchmarking.
Criteria that the systems analysts and users should use to evaluate performance of different systems
hardware include the following:
o The time required for average transactions ( including how long it takes to input data and howlong it takes to receive output )
-
7/22/2019 SAD Written Report
10/27
o The total volume capacity of the system (how much can processed at the same time before aproblem arises)
o The idle time of the CPU or networko The size of the memory provided
Some criteria will be shown I formal demonstrations, some cannot be simulated and must be gleaned from
manufacturers specifications. It is important to be clear about the required and desired functions before gettingtoo wrapped up in vendors claims during demonstrations.
COMPUTER SIZE AND USE
The rapid advance of technology dictates that the systems analyst research types of computers available
at the particular time that the systems proposal is being written. Computer sizes range all the way from
miniature mobile phones to room-sized supercomputers. Each has different attributes that should e considered
when deciding how to implement a computer system.
IV. Acquisition of Computer EquipmentIn acquiring computer equipment,there are 3 main options- buying, leasing, or renting. For each option,
there are advantages and disadvantages to be weighed for each of the decisions. Some of the more influential
factors to consider in deciding which option is best for a particular installation include initial versus long-term
costs, whether the business can afford to tie up capital in computer equipment, and whether the business desires
full control of and the responsibility for the computer equipment.
1. Buying- implies that the business will own the equipment. This is the best option for acquiring computerhardware if the system will be used longer than four to five years.
2. Leasing- the company doesnt own the computer equipment but it pays a monthly payment for the useof the hardware for a fixed duration of use.3. Renting- this is synonymous to lease but the difference is that it only lasts for a short period of time. A
lease is usually given for a specific period of time such as 6 months or years during which both the
landlord and tenant are bound by the terms of the lease while rent has no defined period of residence and
the landlord and tenant can make changes to the rental agreement.
Below are the advantages and disadvantages of the options for acquiring computer hardware.
Advantages Disadvantages
Buying Cheaper than leasing or renting overthe long run
Ability to change system Provides tax advantages of
accelerated depreciation
Full control
Initial cost is high Risk of obsolescence Risk of being stuck if
choice was wrong
Full responsibility

Leasing No capital is tied up No financing is required Leases are lower than rental
payments
Company doesnt own thesystem when lease expires
Usually a heavy penalty forterminating the lease
Leases are more expensivethan buying
Renting No capital is tied up No financing is required Easy to change systems Maintenance and insurance are
usually included
Company doesnt own thecomputer
Cost is very high becausevendor assumes the risk
(most expensive option)
To fully understand the comparisons, here is an example of acquiring computer hardware using the three
options:
-
7/22/2019 SAD Written Report
12/27
From the above data, it shows that the cost of purchase after 3 years is lower than that of leasing or
renting. When a company chooses to purchase the equipment, it will gain full control of it and they will have
the ability to change the system. As systems become smaller, more powerful, and less expensive, more
businesses are deciding to purchase equipment. However, its initial cost is high and it has a risk of being stuck if
choice was wrong.
Meanwhile, when a company uses the computer for less than four years only, they should lease the
equipment. And if significant change in technology is imminent, leasing is a better choice. It also allows the
business to put the money elsewhere where it can be working for the company rather than be tied up in capital
equipment. But leases are more expensive than buying. It usually has a heavy penalty or terminating the lease
and the company doesnt own the system when it expires.
When the company decided to rent the computer hardware, none of the companys capital is tied up, and
hence no financing is required. It also makes easier to change system hardware. This is a best option when the
company contemplated it only for a short-term move to handle nonrecurring or limited computer needs or
technologically volatile times. But as you observe from the above example, cost is very high because the vendor
assumes the risk.
Whether to choose any of the options, the company must identify the period of time they will use the
system, if they afford to tie up capital in computer equipment and if they desire the full responsibility and
control for the computer equipment.
EVALUATION OF VENDOR SUPPORT FOR COMPUTER HARDWARE
What is the reputation of the manufacturer in terms of technical support, maintenance and industry
position? Hardware manufacturers are increasingly designing all equipment to support and function in the client
server environment on which Internet technology is based. Several key areas ought to be evaluated whenweighing the support services available to businesses from vendors. Vendors of comparable quality frequently
distinguished themselves from others by the range of support services they offer.
Here is a list of criteria in evaluating vendor support:
Vendor Services Specifics Vendors Typically Offer
-
7/22/2019 SAD Written Report
13/27
Hardware Support Full line of hardware
Quality products
Warranty
Software Support Complete software needs
Custom programming
Warranty
Installation and Training Commitment to schedule
In-house training
Technical assistance
Maintenance Routine maintenance procedures
Specified response time in emergencies
Equipment loan while repair is being done
Vendor support services should include routine and preventive maintenance of hardware, its quality and
if there is an equipment breakdown, a warranty which will replace permanently the hardware or repair is
required. In software support, it must have all the needed software, customized programs and warranty that will
repair the software breakdowns.
In installing and training, the vendor should provide technical assistance and they must have a
commitment to schedule. Lastly, in maintaining the hardware, vendor should have a routine maintenance
procedures and a specified response time in emergencies.
Because of the competitions among vendors, it has made the idea of producing hardware that is
compatible with competitors hardware important for vendors survival. In deciding which vendor will suit your
needs, it is better to do enough research to feel confident that the original vendor is a stable corporate entity.
SOFTWARE EVALUATION
Software availability is probably the most significant factor in evaluating hardware for instructional
applications. Be aware of the hardware requirements of anysoftware you are considering. Prior to even looking
at available software options, make sure you thoroughly define your needs and what the application you select
should be able to do for you. Nonprofits are process-driven. They receive, acknowledge, deposit and track
donations; they identify, serve and record transactions with clients; and they recruit, hire and manage
employees. Technology facilitates the way your organization manages these processes. A successful software
installation will make this work easier, more streamlined and more effective. But a new system that doesnt take
your processes and needs into account will only make running your organization more difficult.

Some of the decision making surrounding purchase of commercial off-the-shelf (COTS) software,
rental of the software from an application service provider (ASP), or creation of custom software for the
project is analogous to the hardware decision process.

concerns
Loss of potential strategic corporateadvantage regarding innovativeness
of applications
After studying all the advantages and disadvantages of the three options, it is advisable for a company to
identify what they really need. There are situations when to create custom software, when to buy COTS
software and when to outsource software.
When to create custom software
Original software should be created when the organization is attempting to gain a competitive advantage
through the leveraged use of information systems. This is often the case when an organization is creating
ecommerce or other innovative application where none existed. The drawbacks of developing your own
software include the potential for a significantly higher initial cost compared to purchasing COTS software or
contracting with an ASP, the necessity of hiring or working with a development team and the fact that a
company is responsible for the ongoing maintenance because it is the company who created the software.
When to buy COTS software
Commercial-off-the-shelf (COTS) solutions are designed to be easily implemented and interoperate with
existing systems and do not require the need for services or heavy customization. COTS software is prevalent
for its standardized functionality and cost savings, leading to many governments and organizations mandating
COTS software.
COTS offer an alternative to developing custom-made solutions, which tend to be inflexible with other systems
and do not often provide the openness required. Since organizations invest much time and money in custom-
made applications, these solutions are used for long periods of time and are not frequently updated.
When to outsource software services to an Application Service Provider
An ASP (Application Service Provider) is a company that delivers applications - software - through the
Internet and charges a monthly fee. Traditionally, software is sold. You physically receive a CD and you install
it on your hard drive or your office's server. ASPs don't operate this way. They deliver software as a monthly
service and use the Internet as the medium.
This is better to choose when a company is not responsible for upkeep of the service provided. They can
save money and eliminate the hassle that comes with support, maintenance and upgrades. When choosing ASP,
there is a potential loss of strategic corporate advantage that might have been gained through the companys
own deployment of innovative applications created by their employees. The company generally guaranteed
better application availability, better data security, more frequent data backups, disaster recovery and basic,
centralized technical support.

EVALUATION OF VENDOR SUPPORT FOR SOFTWARE AND ASPS
Whether a company decides to buy COTS software or outsource software service to an ASP, they will
be dealing with vendors who may have their own best interests. A company must evaluate the vendor and not
base on the vendors sales talking.
There are six main categories on which to grade software:
Software Requirements Specific Software Features
Performance Effectiveness Able to perform all required tasks
Able to perform all tasks desired
Well-designed display screens
Adequate capacity
Performance Efficiency Fast response time
Efficient input
Efficient output
Efficient storage of data
Efficient backup
Ease of Use Satisfactory user interface
Help menus available
Read Me files for last minute changes
Flexible interface
Adequate feedback
Good error recovery
Flexibility Options for input
Options for output
Usable with other software
Quality of Documentation Good organization
Adequate online tutorial

Website with FAQ
Manufacturer Support Technical support hotline
Newsletter/email
Website with downloadable product updates
Vendors typically certify that software is working when it leaves their supply house, but they will not
guarantee that it will be error-free in every instance or that it will not crash when incorrect actions are taken by
users. Evaluate packaged software based on a demonstration with test data from the business considering it and
an examination of accompanying documentation.
V. Identifying, Forecasting and Comparing Costs and BenefitsSystems analysts have to identify the system that fulfills various information requirements and decisions
to continue with the proposed system.
Forecasting
Forecasting in the simplest meaning is predicting a certain event and in the world of systems analysis
and design, systems analysts are required to predict certain key variables before the proposal is submitted to the
client.
There are five key variables that systems analysts should consider:
1. Scope- the things that the particular proposed project deals with.2. Cost- cash flows of the project.3. Quality- performance or the benefits that will be received.4. Time- the questions when in the proposal project.5. Risk- foundation of the proposed project that is needed to answer the question How sure are we
regarding the outcome of the particular project?
The systems analyst has many forecasting models available. The main condition for choosing a model is
the availability of historical data. If they are unavailable, the analyst must turn into one of these judgment
methods:
1. Estimates from the sales force- a sales forecasting technique that predicts future sales by analyzingthe opinions of sales people as a group.
2. Surveys to estimate customer demand- set of questions are given to the customers regarding to theproject in order to calculate the best choice of project.
3. Delphi Studies- gathers, evaluates, and summarizes expert opinions as the basis for a forecast, butthe procedure is more formal.
4. Creating scenarios- another method that is used by making some scenes to predict what will be theoutcome if that particular step will be done.
5. Drawing historical analogies- ties what is being forecast to a similar item.
-
7/22/2019 SAD Written Report
18/27
If the historical data are available, systems analysts may choose between:
1. Conditional- there is a casual relationship among variables in the model. Common methods in thisgroup are:
Correlation- statistical technique that can show whether and how strongly pairs of variablesare related.
Regression- statistical technique for estimating the relationships among variables.
Leading indicators- used to predict changes in the economy Econometrics- statistical method used by the economists Input/output models- quantitative economic technique that represents the interdependencies
between different branches of a national economy or different regional economies.
2. Unconditional- causal relationship doesnt exist. Graphical Judgment- simple and depends on individual judgment. Moving Averages- seasonal, cyclical, or random patterns may be smoothed, leaving the trend
patterns.
Analysis of time-series data-predicts the future sales by analyzing the historical relationshipbetween sales and time.
Identifying Benefits and Costs
Benefits and costs can be either tangible or intangible and both must be taken into account when systems
are considered. Tangible is something that can be felt or touched unlike intangible it cannot be felt or seen.
Tangible Benefits. Those are measurable in dollars, resources, or time saved.
Intangible Benefits. Difficult to measure but are really important factor in considering whether to
proceed the system or not.
Tangible Costs. Costs that can be determined quite easily and those are costs that require cash outlay ofthe business.
Intangible Costs. Costs that are difficult to estimate and sometimes may not be known and are not
quantifiable.
Comparing Costs and Benefits
There are four techniques for comparing costs and benefits of the
proposed system:
1. Break-even Analysis- systems analyst can use break-evenanalysis to determine the break-even capacity of the proposed
information system. The point at which the total cost current
system and the proposed system intersect is the break-even
point that represents the profitable point of the business. The
figure on the right is an example of break-even analysis on a
small store that maintains inventory using manual system.
The graph shows that the computer would be cost effective if the business sold about 600 units per
week.

7/22/2019 SAD Written Report
19/27
2. Payback- A simple way to assess whether a business should invest in a proposed informationsystem and the number of years of operation that the information system needs to pay back the cost
of investing in it. On the figure below, the payback time of the business is three and a half years.
3. Cash-flow Analysis- This analysis examines thedirection, size and pattern of cash flow.
This figure shows a cash-flow analysis for a small company that is providing a mailing service toother small companies in the city. Revenue projections are that only P5000 will be generated in the
first quarter, but after the second quarter, revenue will grow at a steady rate. Costs will be large in
the first two quarters and then level off.
4. Present Value Analysis- Consideration of Time value of money. We can use this formula in orderto analyze the proposed system is worthwhile on your business:
FV= Future Value
i= Discount rate
n= number of periods
-
7/22/2019 SAD Written Report
20/27
Consider this example:
If we
use present
value analysis
using an
assumed
discount rate,12%, we will end up in this:
As you can see, the total Benefit is P179, 484, and thus less than the costs, which is P183, 855. So, we
will end up in the conclusion that the proposed system is not worthwhile if present value is considered.
Guidelines for Analysis
1. Use break-even analysis if the project needs to be justified in terms of cost, not benefits.2. Use payback when the improved tangible benefits form a convincing argument for the proposed system.3. Use cash-flow analysis when the project is expensive relative to the size of the company.4. Use present value when the payback period is long or when the cost of borrowing money is high.
VI. Activity Planning and ControlSystems analysis and design involves many different types of activities that together make up a project,
one of those activities are planning and control. Planning includes all the activities required to select a system
analysis team assign members of the team to appropriate projects, estimate the time to complete the task, and
schedule the project.
Estimating Time Required
-
7/22/2019 SAD Written Report
21/27
The lowest term level into defining activities is
the Systems Development Life Cycle (SDLC) itself,
whereas the highest extreme is to include every detailed
step, the optimal answer to planning and scheduling lies
somewhere in between. System Analyst breaks the
process into three major phases: analysis, design, and
implementation. The analysis phase is further broken
down into the data gathering, data flow and decisionanalysis, and proposal preparation. The design is broken
down into data entry design, input design, and output design and data organization. The implementation phase
is divided into implementation and evaluation
Systems analyst must also break down these
tasks into further steps to describe it in more
detail. In the figure at the right, data gathering is
broken down into five activities, from conducting
interviews to observing prototype. This particular
data type requires data flow analysis but not
decision analysis, so the system analyst has
written in analyze data flow as the single step in
the middle phase. Finally, proposal preparation is
broken down into perform cost-benefit analysis
prepare proposal and present proposal. Together with these steps systems analyst must have to estimate the time
required to complete each task or activity.
Using Gantt chart for Project
Scheduling
A Gantt chart is an easy way to scheduletasks. It is a chart on which bars represen
each task or activity. The length of each bar
represents the relative length of task.
In the figure, this is an example of two-
dimensional Gantt chart. The time is the
horizontal dimension while the activities
are the vertical dimension. The chart signifies that the current week is week 9 by using the symbol triangle. You
can put a legend on the side that shows the activities that are already completed, or incomplete or partially
completed.
Using PERT Diagram
PERT is an acronym for Program Evaluation and Review Techniques. It is represented by network of
nodes and arrow that are then evaluated to determine the critical activities, improve the schedule if necessary
and review progress once the project is undertaken. Comparing Gantt chart with PERT Diagram using the two
pictures below, we can see that the activities expressed as bars in Gantt chart are the arrows in the PERT
-
7/22/2019 SAD Written Report
22/27
diagram. The length of arrows has nothing to do with the duration of the activity. Circles on the PERT diagram
are the events and can be identified using numbers, letters or other arbitrary from the designation. Path 10-20-
40-50 has a length of 15 days, while the 10-30-40-50 path indicates 11 days to be completed. The longest path
is referred to as the critical path. The critical path in the example is 10-20-40-50 path, while the leeway to fall
behind somewhat noncritical paths is called slack time.
Occasionally, PERT diagrams need pseudo-activities, referred to as dummy activities. Lets use this
picture to explain the dummy activities:
In project 1activity, C
can only be
started if both
A and B are
finished,
because all
arrows
coming into a
node must be completed before leaving the node, whereas project 2, activity C requires only activity Bs
completion and can therefore be under way while activity A is taking place.
Therefore there are many reasons to use PERT diagram over Gantt chart. Those are:
1. Easy identification of the order of precedence.2. Easy identification of the critical path
and thus critical activities.
3. Easy determination of slack time.PERT Example.
First, list the activities that need to beaccomplished along the way. This is an
example of some activities and
estimation of time.
-
7/22/2019 SAD Written Report
23/27
In constructing the PERT diagram, the analyst looks first at those activities requiring no predecessor
activities, in this case A and C. Analyst chose 10, 20, 30 and so on as a node. This how it goes after you
followed the flow of the list by looking at the predecessor column.
Now, we
can identify the critical path, and that is the 10-20-30-50-60-70-80 path because it takes 22 days to beaccomplished.

VIII> The Systems ProposalThe systems proposal is a written proposalthat summarizes the systems analysts work in the business
and includes recommendations and alternatives to solve the identified systems problem. It is essential that great
care is given to writing and presenting it.
Organizing the Systems Proposals
While the charter serves the purpose of identifying objects, determining scope, and assigning responsibilities.
The analyst still need to prepare a systems proposal that includes much of the detail about system needs, options
and recommendations. This covers both the content and the style that makes up the systems proposal.
What to include in the systems proposal:
-
7/22/2019 SAD Written Report
24/27
1. Cover letter2. Title page of project3. Table of contents4. Executive summary5.
Outline of systems study with appropriate documentation
6. Detailed results of the systems study7. Systems alternatives8. Systems analysts recommendations9. Summary10.Appendices
COVER LETTERThe cover letter lists of people who did the study and summarize the objectives of the study are provided in
your cover letter. Also, prearranged time and place for oral presentation of the system proposal can be
included. Keep your cover letter concise (one page maximum) and friendly.
TITLE PAGEIn the title page is include the name of the project, the names of the systems analysis team members, and the
date the proposal is submitted. The title of the proposal must accurately express the content of the proposal,
but it can also exhibit some imagination.
TABLE OF CONTENTSIf the proposal is very short (less than ten pages), you can omit the table of contents since it is unnecessary
on such a short document. The purpose of your table of contents is to indicate the contents of your proposal.
The table of contents can be a great help to readers of long proposals because they can easily locate where
each topic in the proposal is.
EXECUTIVE SUMMARY (including recommendations)Usually, the executive summary is 250 to 375 words and can answer the questions such as who, what, when,
where, why and how of the proposal. It should also include recommendation of the system analysts sincesome people will only have time to read the summary. It should be written last, when the rest of the proposal
is complete.
OUTLINE OF THE SYSTEMS STUDY (with appropriate documentation)The outline of system study with appropriate documentation provides information about all the methods
used in the study, and who or what was studied. Any questionnaires, interviews, sampling of archival data,
observing and prototyping used in the systems study should be discussed here.

DETAILED RESULTS OF THE SYSTEMS STUDYIt includes the details that the system analyst has found out about the system through all of the methods
described. It also presents problems or suggests opportunities that call forth the alternatives presented in the
systems alternatives. Conclusions about problems workers experience when interacting with technologies
and systems that have come to the fore through the study should be noted here.
SYSTEMS ALTERNATIVESThe analyst will present two or three alternative solutions that directly address the aforementioned
problems. Each alternative should be explored separately. Describe the costs and benefits of each situation.
Be sure to include the advantages and disadvantages of the alternatives.
Each alternative must clearly indicate what the users and managers do to implement it.
SYSTEMS ANALYSTS RECOMMENDATIONAfter the system analysis team has weighed the alternatives, it will have a definite professional opinion
about what solution is workable. The system analysts recommendations section expresses the
recommended solution. Include the reasons supporting the teams recommendation so that it is easy to
understand why it is being made.
PROPOSAL SUMMARYThe proposal summary is a brief statement that mirrors the content the executive summary. Meaning it also
gives the objectives of the study and the recommended solution. The proposal should be concluded on a
positive note.
APPENDICESThe appendix is the last part of the system proposal, and it can include any information that the analyst feelsmay be of interest to specific individuals, but that is not essential for understanding the systems study and
what is being proposed.
USING FIGURES FOR EFFECTIVE COMMUNICATION
Tables and graphs as well as words are important in capturing and communicating the basics of the
proposed system. Good design should never be underestimated. Integrating figures into your proposal helps
demonstrate that you are responsive to the different ways people absorb information. Figures in the report
supplement written information and must always be expressed in words. They should never stand alone.
Effective Use of Tables.Tables provide a different way of grouping and presenting analyzed data that the analyst wants to
communicate on the readers. Tables use labeled columns and rows to present statistical or alphabetical data
in an organized way. Each table must be numbered according to the order in which it appears in the proposal
and should be meaningfully titled.

There are some guidelines for the effective use of tables:
1. Integrate into the body of theproposal. Dont relegate them
to the appendices.
2. Try to fit the entire tablevertically on a single page, if
possible.
3. Number and title the table atthe top of the page. Make the
title meaningful and
descriptive.
4. Label each row and column.Use more than one line ifnecessary.
5. Use a boxed table if room permits. Vertically ruled columns will enhance the readability.6. Use footnotes if necessary to explain detailed information contained in the table.
Effective Use of Graphs.There are many types of graphs:
1. Line graphs- Used to show change over time- Changes of up to five variables on a single graph- May also show when lines intersect
2. Column Charts- Can depict a comparison between two or more variables over time- Used more often to compare different variables at a particular point in time- Easier to understand than line graphs
3. Bar Graphs- Used to show one or more variables within certain classes or categories during a specific time
period
- Sorted or organized: Alphabetical, Numerical, Geographical, Progressive order and Magnitude4. Pie Charts

- Used to show how 100 percent of a commodity is divided at a particular point in time- Easier to read than 100 percent stacked column charts or 100 percent subdivided bar charts- Disadvantage is they take a lot of room on the page
There are some guidelines for the effective use of graphs:
1.
Choose a style of graph that communicates your intended meaning well
2. Integrate the graph into the body of the proposal3. Give the graph a sequential figure number and a meaningful title4. Label each axis, and any lines, columns, bars, or pieces of the pie on the graph5. Include a key to indicate differently colored lines, shaded bars, or crosshatched areas
Much of the details that go into a systems proposal is obtained from interviewing, providing questionnaires,
sampling, discovering other hard data, and by observation.
