The Greatest Sin of Management Is Wasting Everyone's Time

Management's greatest sin, according to the author, is the waste of employees' time caused by poorly organized meetings, unnecessary rituals, and over‑staffing in the early phases of a project.

Examples include leaders arriving late to meetings, interrupting discussions for urgent calls, or holding meetings that serve only to reassure managers rather than to solve problems, thereby forcing participants to wait or lose focus.

The author distinguishes genuine work meetings—called only when a problem truly requires collective input—from routine status‑update meetings, which often become ceremonial and serve more to confirm a manager's sense of control than to achieve consensus.

Early‑stage over‑staffing is highlighted as another source of waste: adding too many people at the start of a project inflates costs and rarely improves outcomes, yet political pressures often drive this practice.

Time fragmentation, caused by juggling multiple tasks such as development, maintenance, and support, further erodes productivity by breaking the flow of deep work and forcing frequent context switches.

The article concludes by urging managers to respect the investment represented by their knowledge workers, treating their time as a valuable asset comparable to the cost of a modern wide‑body aircraft, and to adopt lean, consensus‑driven approaches instead of wasteful rituals.
