15 15 Qualität & Informatik Dr. E. Wallmüller Continuous Risk Management (CRM) Principles: - Global perspective - Forward-looking view - Open communications - Integrated management - Continuous process - Shared product vision - Teamwork

16 16 Qualität & Informatik Dr. E. Wallmüller Continuous Risk Management… (SEI, www.sei.cmu.edu/programs/sepm/risk/) FunctionDescription IdentifySearch for and locate risks before they become problems. TrackMonitor risk indicators and mitigation actions. AnalyzeTransform risk data into decision-making information. Evaluate impact, probability, and timeframe, classify risks, and prioritize risks. PlanTranslate riks information into decisions and mitigating actions (both present and future) and implement those actions. ControlCorrect for deviations from the risk mitigation plans. CommunicateProvide information and feedback internal and external to the project on the risk activities, current risks, and emerging risks. Note: Communication happens throughout all the functions of risk management.

20 Software Development Risk Taxonomy (SEI Questionnaire)

21 21 Qualität & Informatik Dr. E. Wallmüller

22 22 Qualität & Informatik Dr. E. Wallmüller Top Software Risks I Personnel Shortfall staffing with appropriate personnel, job matching, team building, securing key personnel agreements, cross-training, rescheduling key people, subcontracting Unrealistic schedule and budget detailed multi-source cost and schedule estimation, designing to cost, incremental development, software reuse, requirement scrubbing, renegotiation with client Developing the wrong software functions organisation analysis, mission analysis, ops-concept formulation, user surveys, prototyping, early user manual development, development of and agreement to acceptance criteria Developing the wrong user interface prototyping, operational scenarios, task analysis,user characterisation (functionality, style, workload) W.B. Boehm

23 23 Qualität & Informatik Dr. E. Wallmüller Top Software Risks II Gold Plating requirement scrubbing, prototyping, cost benefit analysis, designing to cost Continuing stream of requirement changes high change threshold, information hiding, incremental development, deferral of changes to later increment, tight change control, agreement to acceptance criteria Shortfalls in externally furnished components (Procured software) benchmarking, inspection, reference checking, compatibility analysis Shortfalls in externally performed tasks (Subcontractors) reference checking, preaward audits, award-fee contracts, competitive design or prototyping, team building Straining Computer Science Capabilities technical analysis, cost-benefit analysis, prototyping, reference checking, performance analysis, sizing analysis W.B. Boehm

24 24 Qualität & Informatik Dr. E. Wallmüller A Good Risk Statement … For example: The commercial off-the-shelf (COTS) high-speed data link selected by the project team was never envisioned by the vendor to be used in a hardened environment; it may not perform as needed, causing rework and integration slips.

25 25 Qualität & Informatik Dr. E. Wallmüller How to describe Risks?

26 26 Qualität & Informatik Dr. E. Wallmüller Possible Risk Strategies Can I avoid the risk? Can I reduce the risk impact or Can I reduce the risk probability? Can I limit the risk? (Contingency)? Can I transfer the risk? Can I accept the risk ? Risk Reduction Staircase
