|Hundred Tips for a Better Management (Aga Khan Foundation, 1993, 70 p.)|
Numbers can be very useful in analysis and decision-making. But some things cannot be measured precisely.
Be careful not to put too much weight on these kinds of numbers, especially if they are projections. Predicting the future is a risky business.
Gather your best people together so that the collective knowledge, experience and judgement of the group is polled.
Reliance on one individual's judgement, especially for subjective decisions, is always inferior to reliance on an informed group's judgement.
