  1. Excellent case study, Said and your analysis was a good one except for Step 7. If you turn to page 128 in your Memory Jogger 2, you can see that what you want to do is a “before” and “after” assessment. That is, you’ve identified the top 20% of problems and you make some changes (“interventions”), but what you want to find out is if the interventions/improvements you made fixed the problem or did it just move it to another step in the process?

    Other than that, nice work!!!
