The unit of analysis is wrong
Many control systems evaluate clauses, discounts or exceptions one at a time. The customer, however, receives one combined promise. The economic and operational effect therefore lives at the commitment level.
Interaction can be multiplicative
A compressed date increases the cost of custom work. A tighter SLA increases the consequence of a rushed transition. A discount reduces the financial buffer available to absorb both. The terms amplify one another.
Policy compliance is necessary but insufficient
Every term can sit inside an allowed range while the bundle still produces weak economics or fragile delivery. That is why “permitted” is not the same as “safe together.”
How to model it practically
Start with the major non-standard terms and map which cost, capacity or failure mode each one changes. Then ask where two or more terms affect the same underlying resource or downside event.
The repair should target the interaction
You do not have to remove every exception. Change the term that creates the most system relief with the least customer friction.
