Designers iterate more quickly. Data scientists analyze in minutes what used to take days. More output per person means fewer people needed for the same goals. Which means fewer managers.Thu, 06 Nov 2025 00:00:00 GMTManagementAIhttps://thatmoodyguy.com/blog/do-you-struggle-to-do-effective-11s-this-book-can-help/https://thatmoodyguy.com/blog/do-you-struggle-to-do-effective-11s-this-book-can-help/The reality is often far different — rather than being a mechanism for the employee to share questions and concerns, a 1:1 can easily become a mechanism for the manager to get status updates, share information on upcoming projects, and solve problems.

In football terms, I saw myself as the running back — give me the ball and watch me score the touchdown. I couldn't have been more wrong.Wed, 05 Nov 2025 00:00:00 GMTManagementremoving obstaclestech management
