  1. Understanding & controlling the project Production Process

  2. Lecture content • Understanding the project plan • Who should write the plan? • Control • Quality • Time & cost • Environment • Project Failure

  3. Recap on last week • Managing resources • Identifying resources • Resource constraints • Resource levelling (also called smoothing) • The ‘Mythical Man Month’

  4. Understanding the project Project objectives Executive summary Assumptions & risks Contact Points Project Plan Project Milestones Project approvals WBS Assessment & Review standards Network diagram Resource details Budget details Operating procedures

  5. On your own? Advantages Speed Know what you’re doing before forming team On your own? Disadvantages Error identification Missing/incomplete tasks Objectivity Complexity Negativity Who should write the plan?

  6. Team? Advantages Responsibility Understanding Conflict identification cohesion Team? Disadvantages Time consuming Differing expertise Conflict preplanning Who should write the plan? II

  7. Start Publish initial plan Gather Project info Compare progress v. targets Publish revised plan Satisfactory ? No Take remedial action yes Project Completed ? No yes End Project control cycle (Hughes p172)

  8. Control of major constraints • Quality (Time & cost) • Environmental

  9. Time control • Various methods • Gantt charts • Slip charts • Ball charts • Timeline

  10. Slip Charts Slip charts capture when a schedule slips and by how much. They plot expected completion date (Y) against calendar dates (X) Why? Project Completion Prediction: They allow for better prediction of schedule through slip trending and problem diagnostic. Scheduling: slip charts of previous projects can be used to prevent slips in future projects through post mortems, learning cycles, process reengineering

  11. Example Slip Chart

  12. Cost control • Cumulative expenditure chart • Simple way to show expected v. actual cost • Not really useful unless you are using to predict forward costs • See page 182 of Hughes for example

  13. Cost control II • Earned value • Needs 3 measures • Actual cost of work performed (ACWP) • Budgeted cost of work performed (BCWP) • Cost variance = ACWP-BCWP

  14. Cost control III • Estimated cost at completion • Cost variance is incidental • ECAC = total budget + cost variance • Cost variance is indicative • ECAC = project budget x Performance index • (performance index = ACWP/BCWP)

  15. Cost control exercise • ACWP = 120k • BCWP = 100k • Total Budget = 200k • What is the ECAC if the cost variance is believed to be • Incidental? • Indicative?

  16. Cost control Answer • Cost variance • actual cwp - budget cwp • 120-100 = 20k • ECAC incidental • total budget + cost variance • 200+20=220 • ECAC indicative • total budget x performance index • total budget x (ACWP/BCWP) • 200 x (120/110) • 200 x 1.2 = 240

  17. Environmental constraints • Need to be aware of any environmental impact of what you are doing & perform accordingly • Effect of legislation

  18. Reasons for failure • Resources • Time • Expectations • Scope misunderstood • Disagreement among stakeholders
