The TLDHS Safety Tests had grown to over 100 pages of procedures. Understanding the software architecture led us to believe that some of these tests may be redundant.

We decided to thoroughly examine the code and uncovered many places in which different tests exercised the exact same code, using the same parameters and state information. We re-wrote the Safety Tests to remove all these redundancies.

This saved the program weeks of schedule and $10,000s each time the Safety Tests were run.
