Table 4. Risk Matrix
has been implemented to ensure that the trend is going in the right direction and continue to monitor until it drops within acceptable levels. You will investigate if the trend is decreasing and no solution had been implemented. You want to fi nd out why because improvements don’t happen accidentally. When you add it all together you get the risk matrix graph (Table 4). Reading this is relatively simple. We can perform a thorough investigation at any level in the risk matrix but it’s mandatory in the red area, as that is termed unacceptable. The yellow, blue and green areas are where the manager can utilize his/her discretion on how deeply to analyze the issue. In the yellow area, it would be advisable to investigate further. Blue is discretionary and green isn’t obligatory but still needs to be monitored. We have analyzed the problem, can stick it in a graph and investige everything in red and ignore the rest,
right? Wrong. This is a prioritization matrix; (improvement matrix, whatever). If you don’t have anything in red, that’s great — now you can concentrate on the items in yellow, blue and green.
Taxonomy of problem solving: 1. Problem identifi cation 2. Problem analysis 3. Data collection 4. Data analysis 5. Root cause(s) identifi cation 6. Solution analysis 7. Root cause(s) elimination 8. Solution implementation/ prevention
9. Activities monitoring 10. Institutionalize the result
We identifi ed the problem in
part one and went backwards and analyzed the problem here in part two. Next issue we will move forward again and get into data collection, data analysis, and root cause identifi cation.
