This response begins with a charitable but testable assumption: the person probably wants to do good work, so the manager first asks what explains the specific gap. The answer may reveal a practical obstacle, unclear expectation, missing support or a deeper mismatch between the person’s recurring talents and the role. The manager then tests a small intervention or role adjustment on a short cycle, using frequent check-ins to observe whether both performance and engagement improve. If the person remains consistently mismatched, the aim is not to rewire their personality or perfect them through more instruction. The manager should redesign the work, move the person to a better-fitting role or end the assignment quickly and humanely. The decision is based on fit and evidence, while accountability and care remain intact.

Origin

Buckingham explains this sequence in The Diary of a CEO while discussing how strong managers handle underperformance.

Core principles

  • 01Start by assuming that people want to do good work.
  • 02Ask what is happening before assigning motive or punishment.
  • 03High performance depends substantially on fit between talent and role.
  • 04Management should draw out what is present rather than remake someone in the manager’s image.
  • 05Care can require a fast role change or exit when fit remains wrong.

How to run it

  1. 1

    State the observed gap

    Describe the recent behaviour or result without converting it into a judgment about character. Use details both people can discuss.

    Pro tip Weekly check-ins keep the evidence recent enough to be specific.

  2. 2

    Ask why

    Invite the person to explain what is happening before deciding on consequences. Stay quiet long enough to hear their account.

    Pro tip Begin from the assumption that the person is not simply trying to get away with poor work.

    Watch out An initial explanation is a hypothesis to test, not automatic proof.

  3. 3

    Classify the cause

    Distinguish a removable constraint, a skill or support gap and a recurring mismatch between the person and the work. Do not treat all three as the same problem.

    Watch out Do not call someone an A-player or a poor performer without naming the role context.

  4. 4

    Test a fitting adjustment

    Change one relevant condition, responsibility, schedule or source of support. Set a near-term point for reviewing what changed.

    Pro tip A small role tweak can reveal ability that the original arrangement suppressed.

  5. 5

    Inspect performance and fit

    Look for sustained improvement in both contribution and the person’s relationship to the work. Continue only when the evidence supports the fit.

    Watch out Do not mistake one good day for a resolved recurring pattern.

  6. 6

    Make the hard fit decision

    If repeated support and adjustments do not resolve the mismatch, move the person or end the role promptly and respectfully. Frame the decision around the work rather than the person’s worth.

    Pro tip Give people what is right for them, not merely what preserves the current arrangement.

    Watch out Care is not a reason to prolong a role that is visibly wrong for the person and team.

In the wild

Changing a start time

When someone repeatedly arrives late, Buckingham says a strong manager first asks why. If the answer reveals a bus timetable or school drop-off conflict, shifting the start time to 9:30 may solve the real problem without moralising about commitment.

A specific constraint is removed and the new arrangement can be evaluated the following week.

A role tweak changes the performer

Buckingham describes the familiar managerial experience of moving someone who looked like a frustrating C-minus in one arrangement and seeing extraordinary performance after the job changes. His point is that ‘A-player’ labels ignore the role in which the person is being judged.

The manager tests person-role fit before concluding that the individual lacks value.

Common mistakes

Assigning motive before asking

Treating lateness or a missed result as proof of laziness can hide a solvable constraint. Ask first, then test the explanation.

Trying to clone the manager

Prescribing the manager’s own method assumes the employee is wired the same way. Focus on the required outcome and the person’s viable route to it.

Confusing care with delay

Keeping someone indefinitely in a damaging mismatch is not necessarily kind. Make the fit decision once the evidence is clear.

Is it for you?

Best for

Managers dealing with a clear, recent and repeated performance gap where role adjustments are possible.

Not ideal for

Serious misconduct or safety incidents that require an immediate formal process rather than an informal fit experiment.
