10. 2. Managing people “the principal ingredient is people”

11. Project Management Perspectives Enterprise (Business) Perspective –Effecting the “bottom line” Management Perspective –“there are no technical failures only management failures” –Get the job done  PM  Keep staff happy User Perspective –“we just want it to make our jobs better” Engineers’ Perspectives –Architecural and design level, implementation level –High quality workmanship, pride

12. Managing Expectations Managers must have a strong concern for the people they work for and with They must help people work together Must be familiar with team building concepts (covered next week) Must fit personal aspirations to team goals Communicate expectations affectively Measurement of project variables is key Note deviation from plan, take action

Designate leader roles & document responsibilities team leader: proposes and maintains… SPMP configuration management leader:... SCMP quality assurance leader:... SQAP, STP requirements management leader:... SRS design leader:... SDD implementation leader:... code base 2. Leaders’ responsibilities: –propose a strawman artifact (e.g. SRS, design) –seek team enhancement & acceptance –ensure designated artifact maintained & observed –maintain corresponding metrics if applicable 4.

21. 4. Identifying and retiring risks

22. What is a Risk? What is risk? Do all projects have risks? What about software projects?

23. Risk Sources Ordered by Importance (Keil, Cule, Lyytinen, Schmidt) 1. Lack of top management commitment 2. Failure to gain user commitment 3. Misunderstanding of requirements 4. Inadequate user involvement 5. Failure to manage end-user expectations 6. Changing scope and/or objectives 7. Lack of sufficient knowledge/skills

24. What is a Risk? Two types of project risks –Direct Risk - Can be avoided / controlled eg. Project member likely to move Retirement via elimination –eg. job shadowing, replace when necessary –Indirect Risk - Cannot be avoided eg. Comm. time between NS and BC Retirement via mitigation (decrease risk as much as possible) –eg. Use client/server arch. to provide some local functionality

25. The Four Risk Activities 1.Identification – a continual activity 2.Analysis and Prioritization (see spreadsheet) – RBC = Probability * Impact; RAC = RBC * Costspreadsheet 3.Planning – create action plan - to retire or mitigate 4.Retirement or mitigation – includes tracking and control Adapted from Software Engineering: An Object-Oriented Perspective by Eric J. Braude (Wiley 2001), with permission.

27. *:in advance of first meeting M : at meeting **: between meetings Identify and Retire Risks 1.* Each team member spends 10 mins. exploring his or her greatest fears for the project’s success 2.* Each member specifies these risks in concrete language, weights them, writes retirement plans, (see format above) & e-mails to the team leader 3.* Team leader integrates and prioritizes results 4. M Group spends 10 mins. seeking additional risks 5. M Team spends 10 mins. finalizing the risk table –Designates responsible risk retirement engineers 6.** Responsible engineers do risk retirement work 7. M Team reviews risks for 10 mins. at weekly meetings –responsible engineers report progress –team discusses newly perceived risks and adds them

28. In-Class Exercise Each group member takes 5 minutes to identify risks to project success –fill in probability, impact, retirememt method and costs on spreadsheet providedspreadsheet One group member leads all to integrate and rationalize, and add any additional risks Calculate priority (RBC, RAC) of risks Rank priorities, determine most important Suggest methods of retirement or mitigation and assign person responsible for follow-up

29. 5. Choosing development tools and support

Potential CASE Tool Components To support project management –schedule –work breakdown To support configuration management For managing requirements For drawing designs –functional –object-oriented –use-case-based Tracing tools –requirements to designs –designs to code To support testing To support maintenance Adapted from Software Engineering: An Object-Oriented Perspective by Eric J.

33. 6. Creating schedules: high level planning

34. Create an Initial Schedule 1. Indicate the deliverables your must observe –usually includes delivery date 2. Introduce the milestones you need to meet deliverables –e.g., begin system testing well before delivery 3. Designate a time at which all requirements frozen The remaining steps depend on the process used. Assume an iterative process. 4. Show first iteration: establishes minimal capability –usually: keep it very modest, even trivial, in capability –benefit: exercises the development process itself 5. Show task of identifying & retiring risks –starting from project inception 6.Show unassigned time (e.g., week) near middle, consider liberal estimates, add admin tasks/time 7. Complete the schedule Adapted from Software Engineering: An Object-Oriented Perspective by Eric J. Braude (Wiley 2001), with permission.
