5 © All rights reserved “A process or method to analyse the risks to the product, with the intention to utilize the testing effort in the most valuable way.” Product Risk Analysis in a nutshell Classification: HighClassification: Medium Classification: LowProduct RiskRequirement “The likelihood that a product fails in relation to the conceivable damage when a product fails in production.” 5

6 6© All rights reserved Risk & Requirement Based Testing in a nutshell Risk without requirement: Add requirement (a fault found early) Remove Risk (no worries about nothing) Requirement without Risk Add product risk (improves coverage of test) Remove Requirement (only make what is needed) Requirements Product Risks

8 © All rights reserved Risk analysis were not translated to the Backlog which makes it difficult to utilise a risk based approach. Merging or splitting features invalidate the PRA. 8

9 © All rights reserved Risk analysis were not updated every iteration, which could mean that they will be out dated within a sprint. PRA isn’t updated 9

10 © All rights reserved Risk analysis were only done from the requirements which meant that some product risks were missed. PRA are done with tunnel vision Specify Test Cases Specify Test Cases Determine Risk Determine Risk Order Requirements Order Requirements Analyse Requirements Analyse Requirements Analyse Risk Order Requirements Order Requirements Analyse Requirements Analyse Requirements Specify Test Cases Specify Test Cases 10

11 © All rights reserved Risk analysis were done, but the outcome wasn’t taken into account in the planning meetings. Risk class isn’t used in planning meeting Team Velocity = ± 14 Story Points High = 3 n Medium = 1 n Low = ½ n 13

12 © All rights reserved Risk analysis were done, but the risks where prioritised using MoSCoW, which doesn’t automatically fit in a Agile environment. Testing is prioritized based on product risks Sprint 1 Sprint 2Sprint 3 12

Plan to iterate and evolve your analyses in sync with the sprints. Don’t use the backlog as your only starting point for your analyses. The result of your analyses is essential in the planning meeting. Order your testing effort in the small. 30 B.W.F.P.M.
