Bear in mind that (a) and (b) areused primarily as internal control functions (although you maychoose to report them outside the team). Theyre used for eval-uating (c). At the risk of being repetitive, your primary focusshould always be on evaluating where you think youre goingto end up.There are two reasons for this.First, you must take intelligent and meaningful correctiveaction with the end point in mind. Guiding the ship must includemore than just steering it back on course; it must also includerecognizing that theres an object up ahead that youre going tohave to steer around or winds around the upcoming point ofland that have kicked up since you started your voyage.1/ 2Thefuture will always be different than expected at the outset of theproject. Assumptions will be revised, operating conditions willchange, and new things will be thrown in your path. Sometimes,actions you take now must compensate for future sources ofvariance as well as variances created though past performance.The second reason you need to focus on the end point per-tains to management reporting. In most cases, what will proba-bly interest them most is a prediction of where you think youregoing to end up: this is the type of information they need to runthe business. Being able to report to your management thatyoure two weeks behind schedule or $10,000 over budget rightnow may or may not be of value to them. Reporting that youexpect the project to be completed three weeks late or $15,000over budget is much more likely to be of value.Project Management 162W...。

Software project management
Concerned with activities involved in ensuring that software is delivered on time and on schedule and in accordance with the requirements of the organisations developing and procuring the software. Project management is needed because software development is always subject to budget and schedule constraints that are set by the organisation developing the software.

The project plan
The project plan sets out:
The resources available to the project; The work breakdown; A schedule for the work.

Types of project plan
Plan Quality plan Description Describes the quality procedures and standards that will be used in a project. Describes the approach, resources and schedule used for system validation. Describes the configuration management procedures and structures to be used. Predicts the maintenance requirements of the system, maintenance costs and effort required. Describes how the skills and experience of the project team members will be developed.
Module 6
Project Management
Objectives
Apply project management tools, techniques, and methods to a systems development project (for example, Gantt Chart, staffing plan, risk analysis, Microsoft Project).
Software management distinctions
The product is intangible. The product is uniquely flexible. Software engineering is not recognized as an engineering discipline with the sane status as mechanical, electrical engineering, etc. The software development process is not standardised. Many software projects are 'one-off' projects.

Management commonalities
These activities are not peculiar to software management. Many techniques of engineering project management are equally applicable to software project management. Technically complex engineering systems tend to suffer from the same problems as software systems.
Validation plan Configuration management plan Maintenance plan Staff development plan.

Project planning
Probably the most time-consuming project management activity. Continuous activity from initial concept through to system delivery. Plans must be regularly revised as new information becomes available. Various different types of plan may be developed to support the main software project plan that is concerned with schedule and budget.

Proposal writing. Project planning and scheduling. Project costing. Project monitoring and reviews. Personnel selection and evaluation. Report writing and presentations.
Project staffing
May not be possible to appoint the ideal people to work on a project Project budget may not allow for the use of highly-paid staff; Staff with the appropriate experience may not be available; An organisation may wish to develop employee skills on a software project. Managers have to work within these constraints especially when there are shortages of trained staff.
Project planning process
Establish the project constraints Make initial assessments of the project parameters Define project milestones and deliverables while project has not been completed or cancelled loop Draw up project schedule Initiate activities according to schedule Wait ( for a while ) Review project progress Revise estimates of project parameters Update the project schedule Re-negotiate project constraints and deliverables if ( problems arise ) then Initiate technical review and possible revision end if end loop
