Watch out for some kind of reusability...

Some month ago Hollander has warned us about The Seven Deadly Sins of Reusable Asset Development. For Tom, they are:

1. Not harvesting from proven practices.
   
2. Solutions that are more complex than the problem.
   
3. Custom solutions to generic problems.
   
4. Diverging too far from the base platform.
   
5. Lock-in to a single company or architectural approach.
   
6. Not considering ongoing maintenance and support costs.
   
7. Not focusing on usability, documentation and training .
   

I can relate to some of these - they make me remember some of my own old mistakes :) From the new ones, I recognize to have a slight tendency for number 5 (Lock-in to a single company or architectural approach).
