Not sure if this is the right fit?
Consider The Mythical Man-Month by Frederick P. Brooks Jr.. Recommended by 15 sources.
“Reading it feels like listening to Frederick P. Brooks Jr. deliver a set of terse, experience-packed essays drawn from his time managing the IBM System/360 project. The most useful material: concise maxims about staffing, scheduling, documentation, and interface boundaries that give language for hard organizational limitations. Limits include dated technical examples, a single-author, prescriptive voice, and repeated restatements; readers looking for modern case studies or practical templates will find no hands-on exercises. Best read slowly to mine specific heuristics rather than as a how-to playbook.”
