Simple way of gathering metrics

Despite of huge investment in tracking tool still process oriented mangers struggle with gathering meaningful metrics. According to Tom Demarco a useful metric should have the following qualities:
1. It must be a consistent indicator of the cost factors to be projected
2. It must be available early enough to satisfy reasonable political constraints imposed on the estimating process

A very simple and low cost way of gathering useful metrics is suggested by Esther Derby which you draw a picture of all the modules and each time there is a production problem put a color coded dot on the module – red for a crash, yellow for an issue with a workaround and blue for a data problem. You will see quickly the most error-prone modules, and gradually you can tackle those problems one by one.
