Whether to pay up front (emotionally, financially, or even psychologically) or to pay later for outcomes that can’t immediately be measured isn’t the hardest decision in people management.
Determining what outcomes, we want to achieve that won’t be easy to measure also isn’t hard.
Analyzing outcomes, whose significance isn’t immediately apparent, is also not a hard thing to do.
The hard thing is having the courage to commit to the indecipherable outcome, measuring and analyzing the outcomes’ significance in a meaningful way, and then pay the cost (whatever that may be) of executing on the results of the analysis.
Too often, cowardice in the face of indecision scales.
