Looking at this graph, I am now realizing that there are two opposite ways to interpret it.
Many will say “It means, let’s promise more, and we will achieve more“. That is not what I meant. My idea is that the right side of the graph is the bad side. It IS a failure.Why? Because that gap between “promised“ and “achieved“ is expensive:
- wasted time and money due to inaccurate planning
- poor discipline, as underdelivering becomes a norm
- additional external communication is needed to explain the gap and restore the trust
EVEN if overpromising leads to higher achievement (which I am not sure of), it does not compensate for the cost of the gap.
And it only works short term, anyway.
