An insightful article about decision-making velocity and drag: https://www.antmurphy.me/newsletter/decision-velocity-and-drag.
Many organizations concentrate on making their tooling and delivery processes more effective, yet they overlook or disregard the importance of verifying how they make decisions.
Do your teams have the authority to make decisions on their own? Or do they have to involve managers in any issues or changes to a predetermined course of action? Or are most decisions made by a council of senior leaders, causing delays in feedback?
Likewise, does your organization accept decisions made with only 70%-80% of the information necessary, or does it strive for perfection, resulting in extended deliberation over every pro and con?
No co-pilots or process improvements will help if decision-making power is not delegated to the team that is closest to the action or problem at hand.
