Priority Dilution

Definition

Priority dilution occurs when an organization declares many initiatives "top priority" simultaneously, which is logically equivalent to declaring none of them a priority — there is no ordering left to act on. It differs from having too much work (too much WIP): a team can have a modest workload and still be crippled if no one agrees on the order to attack it, because contested priority causes people to start new things instead of finishing existing ones, which is exactly what inflates WIP and cycle time.

In the Book

Section 1.4 profiles a team of forty-one IT Operations engineers at a gaming company juggling thirty-three projects — more than half tagged "priority one." Stand-ups produce foot-shuffling silence instead of status, because engineers won't name blockers and project managers can't get clarity on which of the four listed team priorities (capacity expansion, disaster recovery, security, site reliability) actually governs today's work. DeGrandis diagnoses the shared root cause as invisible priorities, not insufficient effort: "no one is willing to point out that the team is being asked to do too many projects at one time."

She backs this with a second case: a team with thirteen initiatives against a headcount smaller than that number delivered a report six months late; cutting initiatives to seven both shortened their weekly priority meetings and sped delivery — demonstrating that trimming the priority list, not adding people, was the lever. Her formulation, quoting Ross Garber: "Many things may be important, but only one can be the most important." She explicitly ties Thief Conflicting Priorities back to Thief Too Much WIP as its underlying cause: failure to prioritize is one of the primary reasons WIP balloons in the first place.

Why It Matters

This gives a diagnostic test for a specific organizational pathology: if you hear "when will my thing be done?" and "my thing is high priority!" as recurring refrains, the fix is not more capacity or better estimation — it's forcing a single, visible rank order and defending it. It applies anywhere multiple stakeholders can each unilaterally declare their own request the top one without a shared arbitration mechanism.
