	Disadvantages of the COTS approach
- Exactly the right solution may be elusive
 - The COTS product may be subject to changes
- Driven by other users
 - Or market forces
 
 - A newer and better product arrives
- That essentially serves the same purpose
 - But requires a reworking of the custom system
 
 - Shelf-life is typically limited
- And product support is eventually abandoned by the supplier
