Notes on Project Management

Prepared for the entrepreneurship

course at WIU, Feb. 23, 2006

by Brian M. Davies, Physics Dept.

Characteristics of Projects

• Goal: something not done before

• Product: a specific accomplishment

• Resources: people and things

• Size: program > project > tasks > jobs

• Marketplace: personal or family, organization-sponsored, customer-sponsored, subcontracted, or government.

Project Management Process- has 5 major stages:

• Defining the project’s goals

• Planning - how to satisfy Triple Constraint

• Leading - guidance to human resources, subordinates, subcontractors

• Monitoring - measure, control, correct plan

• Completing - meet goals, documentation

The Triple Constraint on Projects

• Project manager must consider 3 constraints

• Performance specifications (technical folks may focus too heavily on this)

• Time schedule (due dates)

• Money budget - dollars for materials, supplies, internal support, subcontracts, etc., and for labor hours (equivalent to dollars !)

Obstacles to satisfying the constraint on performance

• performance problems - fail to meet specs !

• poor communication between customer and contractor (definitions, culture, detail)

• overly optimistic assumptions (ambition)

• poor design, mistakes in carrying out the contract, errors by workers and managers, accidents.

Obstacles to satisfying the constraint on time schedule

• overemphasis on performance vs. meeting time and budget constraints (engineers may try to achieve breakthroughs and ignore time and budget required by customer)

• resources not available when needed

• performance specs changed mid-project

• subordinates fail to give proper priority

Obstacles to satisfying the constraint on cost and budget

• Failure to meet time constraint usually costs more because of lack of efficiency.

• Reducing cost estimates to win bid causes a built-in cost overrun from the start.

• Initial cost estimates are often too optimistic.

• Mistakes, bad cost management, cash flow.

Stage 1: defining project goals

• Framework - reject losing projects

• Requirements, feasibility, value of project

• Proposal - winning the competition

• Proposal process - S.O.W, plan, checklists

• Negotiations and contracts

• Legal issues and regulations

Stage 2: planning the project

• a. Where are you now?

• b. Where do you want to go?

• c. Define the way to get from here to there.

• Plans will include:

• Resource requirements: people, things, $$$

• Timing: scheduling these resources

Coordinate and communicate!

• People who will do the work know more about it than others; get them to help plan!

• Plan to make it their task as well as yours.

• Money, commodities, and some internal support may be easy to obtain.

• Human resources may not be available at any reasonable cost (hiring is not easy).

Establish a basis for control

• Sufficient authority needed for resource allocation, not based on “mutual favors”.

• Methods of monitoring progress of project are needed to allow adjustment when deviations from plan are recognized.

• Plan better - to avoid continual crises and the need for constant “firefighting”.

Some planning issues

• Uncertainty and risk: checklists, contingencies, participant assumptions.

• Choices between options during project performance, early ordering of supplies, (example of assigning subordinate tasks).

• Planning is a way of simulating the project.

Work Breakdown Structure

• SOW - Statement of Work: contains the three constraint topics: deliverables (with specs if needed), schedule, and budget.

• WBS: divide project into tasks or activities.

• The WBS should be divided into tangible deliverable items (hardware items, software packages, interim reports in R & D).

Scheduling Tools

• Bar charts (Gantt charts)

• Milestones (based on key events)

• - but both of these are useless for specifying interdependencies and clarifying activities.

• Network diagrams - PERT, CPM, etc. show interdependencies and precedence.

A shorter Gantt chartNote how it fails to indicate dependencies.

No task assignments are shown. Milestones might be inferred from the endpoint of the timeline for each task.

• Bar charts can show percentage completion and can be used to estimate schedule performance, but fail to indicate dependencies that could cause project to be late.

PERT diagrams

• “Program Evaluation and Review Technique”• Event-oriented - events labels go in the nodes of

the diagram, surrounded by boxes, ovals, or other closed curve.

• Often used in R & D where time needed for an activity is uncertain (aerospace, science, leading-edge engineering projects)

PERT/CPM diagram conventions

• Event labels go in the nodes of the diagram, surrounded by boxes, ovals, or other closed curve.

• Activities are labeled on the arrows of the diagram, with nodes to delimit start and finish.

Start activity Finish activityActivity

CPM - Critical Path Method

• Activity-oriented (activity labels go on the paths between nodes)

• Often used in construction where the time needed for an activity can be controlled.

• Dummy activity labels can indicate precedence requirements.

• The critical path is often highlighted: it is a path through the network which contains activities which must stay on schedule.

Critical path is shown as the thickest line.
