In a previous life the Watchman worked as a technology consultant. When a client would question the cost of a project, he would tell them that there are three parameters that define a project and the client is welcome to change any two of them. The third one will then compute itself.
- Cost
- Scope of Work
- Delivery Date
If the client wanted the project to cost less while still being done quickly, then he or she would have to accept a reduction in the scope of work. Want all the bells and whistles for a low price? Then don't expect it to be finished quickly. You can control any two, but not all three.
A similar triad exists in the public sector:
- Personal Taxes (Cost)
- Entitlements (Scope of Work)
- Public Debt (Delivery Date)
The only difference is that in the private sector the third item refers to the delivery date of the work while in the public sector it refers to the delivery date of the bill.
