  1. A Case Study onScenario-Based Process Flexibility Assessment for Risk Reduction Josef Nedstam, Martin Höst, Björn Regnell: Dept of Communication Systems Jennie Nilsson: Ericsson Mobile Systems

  2. Process Flexibility • Using the same process in different projects • Using a process in an environment that changes over time • Having a process that is easy to improve/change • Having a process that does not need large changes

  3. Assessing Process Flexibility • A metric for process flexibility – the risk associated with a process • Method: Risk analysis for decision support • Scenario-based – from SAAM: • Makes abstract attributes concrete • Adapts to the situation at hand

  4. The Assessment Method

  5. Process Interviewees Issues Abstract Scenarios Concrete Scenarios Scenario Generation

  6. Interviewees: Process Developer Project Manager System Designer Object Manager Interview Issues: Reuse Architecture Platform Vision Communication Platform vs Product Architectural Changes Requirements Quality Technical Evolution Integration Testing Market … The Case Study

  7. The Case Study • Risk Analysis • Generate scenarios from issues • Determine Cost & Probability of scenarios • Calculate Risk: Cost * Probability • Backtrack issues • Feedback

  8. Scenario Risks

  9. 4. Arch-Perfomance- Integration 15. Pay with SIM-card 6. UI-Change 16. Common Tool 17. Bottlenecks in 2:nd product 35. Metrics/Estimates 20. Test-Reqirements 23. Supplier out of business 21. Test-Req in Line Organization Related High-Risk Scenarios

  10. Results • Affected Issues: • Architecture and Reuse • Resources and Competence • Process • Method Conclusions: • Low cost • Easily performed with interpretable results • Effective, but can identified areas be improved?

  11. Summary • Process Flexibility • Scenario-Based Method for Risk Assessment • Case Study on Ericsson Mobile Communications • Risk Areas: Architecture and Reuse, Resources and Competence, Process • Method: Low-Cost, Feasible, Effective
