If a bunch of solutions are implemented at the same time, it may be difficult to quantify which changes had an impact. At the same time, we see multiple solutions being implemented all of the time. The key to doing this is identifying a measure or indicator for each solution that helps determine the success/impact. For example, if you implement a new form and a new process to improve Cycle Time. Well, how do you know which had greater impact? After measuring the change in cycle time to confirm if there is an improvement, you might also look at how many “new” forms were received or were in circulation. Also, you might do a Process Walk to observe the process, to see if people are actually following the new process. The idea here is to collect additional support data around that specific solution and the root cause that the solution is designed to address.
