What you should be doing Update web site and functional spec

per meeting Write a draft contract

Post on web email me when you have it done and I

will give you feedback as soon as possible

Signed contracts due next week. You do not need to schedule a special meeting with clients to sign

Contract Content Key goals and requirements Deliverables

Deliverable dates (milestones) Software Testing Documentation (user, administrative, maintenance)

Client responsibilities Meetings (when and with whom)

Constraints, risks and dependencies What needs to be included Template

Project Management Tools

PERT ChartsGantt Charts

PERT Charts Critical path analysis or method

Program Evaluation and Review Technique Also known as activity networks

Developed by Navy in 1958 Three stages:

Planning (tasks and sequence) Scheduling (start and finish times) Analysis (float and revisions)

Two different models Activities are nodes (most common) or arcs

Pert Chart Activity Box

Pert Charts

CPM: Critical Path Method

Alternative to PERT Dupont 1957 Graphical view of project Predicts time required to complete Shows which activities are critical

to maintaining the schedule

Planning: PERT and CPM1. Identify the specific

activities and milestones. 2. Determine the proper

sequence of the activities.

3. Construct a network diagram.

4. Estimate the time required for each activity.

5. Determine the critical path.

6. Update the PERT chart as the project progresses.

1. Specify the individual activities.

2. Determine the sequence of those activities.

3. Draw a network diagram. 4. Estimate the completion

time for each activity. 5. Identify the critical path

(longest path through the network)

6. Update the CPM diagram as the project progresses.

Gantt Charts

Milestone charts Invented by Harvey Gantt in 1916 Advantages

Less detailed Amenable to management overlays

Gantt Chart

Gantt Chart with Overlays

Scheduling Steps and Tools Put together minimal solution

Primary requirements Start with external commitments

Product descriptions Milestones from contract

Introduce internal milestones Work breakdown structure Product Flow PERT Chart, Gantt chart

Focus on the risks Risks from contract

Add next level of features where possible Secondary requirements

Project Plan for this project Use simple Excel spreadsheet (or equivalent)

What you should be able to tell from your project plan

What is Joe working on this week? Who can help me if I run into

trouble? If I have to choose an activity to be

late, which one will impact the project more?

Reviews and Inspections

Reviews and Inspections Why?

Developer can’t correct unseen errors More eyes to catch problems Earlier is cheaper

Integration fix typically 3-10 times the cost at design

Difference in terms Review implies completed work, often

reviewed by someone at a different level Inspection implies peer review of work in

progress

Inspections

Introduced by Michael Fagin in 76 (IBM Systems Journal)

Formalized process Specific roles and steps Heavy preparation and follow-up

Used for documents and code
