Great leaders obsess over the end, not the means. Process is important, but you should only care as much as is necessary to get your team moving towards a specific, positive outcome that solves a problem.
To be rigidly fixated on a particular tactic is to lose sight of the bigger picture.
Concern yourself about who will get credit in the end, and get ready for political infighting and bickering.
Everyone on the team must be obsessed with solving the problem. With that foundation, the possibilities are endless, and the overall chances of success are much greater.
