What do you mean by 'doing' rather than 'deciding' especially at the c-suite level ?
I thought that's what c-suites are paid to do - 'strategy' and 'capital allocation'.
Any example company you have in mind that has leadership actively 'doing' ?
In contrast, a "discusser" or "decider" makes decisions in order to satisfy the social role of making decisions, but often with a lack of surety, clarity, follow-through or commitment. Perhaps in fear of missing some greater opportunity, or fear of being credited with some failure, their decisions are not organized in a way that actually effects some end.
It’s a two way street. Managers can only see the forest, but engineers are capable of seeing both the forest and the trees.
