To illustrate the effect of the process in terms of tangible improvements, let us turn to one of the outcomes: the decision of celebrating weekly Lean Coffees. These structured meetings gave rise to a good number of methodological and technical initiatives. For instance, two testing policies were established:
1) Automated tests should achieve at least 60% code coverage in new developments. 
2) Every change request of a system under maintenance should include 1-10 automated tests. 
We do not have data about the outcome of the first policy application since no new developments were addressed during this experience. However, the application of the second one resulted in a relevant growth in the number of automated tests. Before its application, less than 7% of the projects under maintenance included automated tests whereas more than 50% of the projects incorporated them by the end of the experience.
