Expensive mistakes. A sequel

This talk is a next step forward after 2017, April's talk in dealing with expensive BA mistakes. Several new project patterns will be considered to see the situation from different angles and to learn how to control your fate.

1. What does expensive mistake mean
2. When the coast of mistake becomes significant
3. Suggested way to systematize mistakes 
4. Patterns in mistake identification
5. Hints and tips
   
6. Conclusions
