How to Pinpoint the Controlling Factor Across the Performance System
Once more than one plausible cause is on the table, narrow the list to the one that actually controls the behavior. Sort candidates by type, separate knowledge gaps from blocks, test against evidence, and name the primary driver.
Developing
Start here. Build the foundation.- 1
Take your list of possible causes and assign each to a category: unclear information, missing resources, or misaligned incentives. Keep a fourth bucket for causes that sit with the person, a real capacity or knowledge limit, so those are not forced into an environmental one. Sorting by type stops an information fix landing on an incentive problem.
- 2
For each cause, ask whether the person could do it today if their job depended on it. If yes, it is not a knowledge gap; label it can-but-blocked. If no, label it cannot-do. Settle the label before choosing any fix.
Proficient
Build consistency and rhythm.- 3
Hold each surviving cause against what you actually observed, not what feels most likely, and drop any cause with no observation behind it. A favorite theory the evidence has already ruled out only widens the search. Keep only causes an observation supports.
- 4
Among the causes that survive testing, name the one whose removal would move the behavior most, and write down why it outranks the others. Ranking is the point: treating every contributing factor as equal spreads effort across factors that do not matter.
Mastered
Operate at the highest level.- 5
When the same controlling factor recurs across cases, write it into a shared library with the category, the confirming observation, and the path that found it. Point the next colleague at the pattern instead of walking a new case from scratch. A pattern that stands alone saves the team the diagnosis time.
Common Pitfalls
Avoid the common failure modes.- A favorite theory survives after the evidence has ruled it out. Hold only causes with an observation behind them.
- Causes get listed but none gets named as the one that controls the behavior. Pick the factor whose removal changes the outcome most and say why.
- An information fix gets applied to what is actually an incentive problem. Sort the cause by type before choosing the fix.
