Explanation of the Epstein-Heisenberg Principle
In any project, only two of the three parameters can be defined at any given time. Those parameters are the task, the time, and the money:
- If the task is known and a time limit is established, then the cost cannot be estimated (or even fathomed).
- If the time and the available resources are clearly detailed, then the project definition must change.
- If the project definition is clear and the budget is set, then the time-to-completion will be extended indefinitely.
