For any objective to be successful, you need the right person in the right place at the right time.
This is important especially in mission-critical projects.
For instance, in the Manhattan Project to develop the A-Bomb, the presence of Einstein, Fermi and Oppenheimer on US soil ensured that the theoretical and practical aspects of the project went through successfully.
All the 3 factors have to concur, or else the project will not succeed.
Do you agree ?
