Контекст (это презентация из области управления проектами):

ESTIMATION SKILLS

- PERT weighted estimates
- (Optimal + (4 * likely) + Pessimistic) / 6
- Throttle without dumb padding/buffering.
- Optimal = everything goes well
- Pessimistic = many things go wrong

You can change weightings at a project level
Risky projects: (O + 4L + 2P) / 7

Заранее большое спасибо
