Addition to the Epstein-Heisenberg principle
In research and development, only two of the existing three parameters can be determined simultaneously. These parameters are: job, time and resources ($).
1. If you know what the task is, and there is a time limit for its completion, you cannot determine its cost.
2. If time and resources are well defined, it is impossible to know how much of the research and development assignment will be carried out.
3. If the purpose of research and development and the exact amount of money required to complete an assignment are precisely defined, it cannot be predicted when the assignment can be completed or whether it can be completed at all.
If someone is lucky enough to pinpoint all three parameters, then they are not dealing with research and development.
