You are a Test Manager and have started a program of test process improvement. You are following the IDEAL model and have completed the first three phases, now you are ready to go further. Which TWO of the following activities will enable you to complete the remaining phases of the IDEAL model?

Show Suggested Answer Hide Answer
Suggested Answer: C, E

According to the ISTQB glossary:

The IDEAL model comprises five phases: Initiating, Diagnosing, Establishing, Acting, and Learning.

''Acting'' includes piloting and implementing improvements (e.g. trialing highest-priority improvements).

''Learning'' includes evaluating the success and capturing lessons learned (e.g. checking if benefits were achieved).

Therefore, C (trial highest-priority improvements) belongs to the Acting phase, and E (benefits check) aligns with Learning.

I think we practiced a question similar to this, and I remember that deciding on the approach is key. So option D might be relevant as well.

I feel like checking the benefits achieved from previous improvements is crucial too, but I can't recall if that aligns with the IDEAL model's later phases.

I'm not entirely sure, but I think trialing a high-priority improvement in a pilot project could give us valuable insights. So maybe option C?

I remember we discussed the importance of prioritizing improvements based on ROI in our last study group. It seems like option B could be a solid choice.
