7 J. Nawrocki, Doskonalenie Procesów.. Delphi method Rand Corporation, Boehm’81 A few experts individually produce effort estimates.A few experts individually produce effort estimates. A Delphi process is used to reach a consensus.A Delphi process is used to reach a consensus. Pythia

8 J. Nawrocki, Doskonalenie Procesów.. Delphi method 1. Experts get the specification and an estimation form 2. They meet for discussion (project goals, assumptions, estimation issues) 3. Each expert anonymously lists the tasks and estimates the size 4. The estimates go to the estimate moderator. He tabulates the results and returns them to the experts. The Delphi procedure The estimate moderator

9 J. Nawrocki, Doskonalenie Procesów.. Delphi method Estimator: Jerzy Nawrocki Date: Project: Sorting routine The estimates from the 1st round: e E M e e e E M e e e - estimates, E - your estimate, M - median estimate Your estimate for the next round: Hours. A rationale for your estimate:

10 J. Nawrocki, Doskonalenie Procesów.. Delphi method 5. The experts meet to discuss the results. They review the tasks they have defined but not their size estimates. 6. The procedure is repeated from step 3 until the estimates are acceptably near The Delphi procedure The estimate moderator

17 J. Nawrocki, Doskonalenie Procesów.. Progress tracking Problem: how to track a progress when a sequence of tasks is rearranged? Earned Value Method: Each task is assigned a number of credit points. Each task is assigned a number of credit points. To earn the points assigned to a task, the task must be completed. To earn the points assigned to a task, the task must be completed. The points reflect ‘time complexity’ and are normalised to 1000 points.The points reflect ‘time complexity’ and are normalised to 1000 points. T1T2 T1T2

24 J. Nawrocki, Doskonalenie Procesów.. Risk management What is a risk?

25 J. Nawrocki, Doskonalenie Procesów.. Risk management Two approaches to risk Reactive Proactive

26 J. Nawrocki, Doskonalenie Procesów.. Risk description Risk management ProbabilityImpact catastrophiccatastrophic criticalcritical marginalmarginal negligiblenegligible

27 J. Nawrocki, Doskonalenie Procesów.. RMMM Risk management RMMM = Risk Mitigation, Monitoring, and Management Mitigation= minimising the probability Monitoring= observing factors/indicators Management= if it happens..

28 J. Nawrocki, Doskonalenie Procesów.. Risk analysis Risk management IBM: > 100 risk factors For each risk factor an MMM plan. Risk management becomes a project in itself! Pareto analysis: the principle

29 J. Nawrocki, Doskonalenie Procesów.. Risk management StrengthsStrengths OpportunitiesOpportunities WeaknessesWeaknesses ThreatsThreats Internal External Positive Negative

30 J. Nawrocki, Doskonalenie Procesów.. Summary Work statement & SWOT Effort estimation & Delphi method Schedule estimating Risk & RMMM Plan Progress tracking, EV and corrective actions

31 J. Nawrocki, Doskonalenie Procesów.. Quality assessment 1. What is your general impression ? (1 - 6) 2. Was it too slow or too fast ? 3. Did you learn something important to you ? 4. What to improve and how ?
