Is it the person or the job? A performance problem diagnostic.

Before you sit someone down about a performance gap, check whether the job is set up for them to succeed. Thirty-five questions show where the cause most likely sits.

Answer for one person and one specific task or standard, not their performance in general. “Not sure” is a useful answer: it often means you need to ask them.

Legal implications

Are there any legal implications to this performance issue?

Area 1 of 6Knowledge and skill

Could they do it if their job depended on it?

They have done this task to the required standard before.

They do it often enough to stay in practice.

They have been trained or shown how, with enough practice to get it right.

A guide, checklist or worked example is there when they need it, and it is actually useful.

Their performance is improving with experience rather than standing still.

The task is within their capacity as the job is currently designed.

Area 2 of 6Standards

Do they know what good looks like, and does everyone agree?

They know exactly what they are expected to deliver.

They know when it is expected, and what takes priority when demands clash.

Everyone they answer to agrees on what is needed and when.

The standard is written down somewhere they can see it.

They know how their work on this will be judged.

Area 3 of 6Measurement

Can anyone, including them, see the gap?

This part of their work is actually measured or checked.

The measure reflects the task itself, not something next to it.

It looks at results, not just whether they followed a preferred method.

It is objective: two managers looking at the same work would reach the same view.

Area 4 of 6Feedback

Do they hear how they are doing, soon enough and specifically enough?

They are told how they are doing on this.

They hear soon enough to do something about it.

They hear often enough, not just at review time.

The feedback is specific enough that they could say what to do differently.

It is about things they can control.

It is accurate, and given in a way they can accept.

Area 5 of 6Conditions

Does the job let them do it?

The procedure for the task is clear and workable.

There is enough time to do it properly alongside everything else.

The tools, systems and equipment they need are available and working.

The information they need is available and accurate.

Interruptions and competing demands are at a manageable level.

They have the authority the task needs.

The job is realistically doable by one person, with support at peak times.

Area 6 of 6Incentives and consequences

What happens to them when they do it well, and when they don’t?

They see the task as worthwhile.

They believe they can do it.

Doing it well leads to something they value: recognition, progression, interest, reward.

They can see the link between doing it well and what follows.

Doing it well is not quietly penalised (more work, duller work, friction with colleagues).

Doing it badly is not quietly rewarded (someone else picks it up, they avoid a task they dislike).

There is some satisfaction for them in the work itself.

Why diagnose before you discuss

When someone’s work falls short, the instinctive explanation is about the person: they can’t, or they won’t. Sometimes that is right. Often the cause sits in the job around them – a standard nobody wrote down, two people giving conflicting instructions, feedback that arrives months late, a system that doesn’t work, or a quiet incentive to do the task badly. Managers tend to reach for ability or attitude first – in our experience partly because the person is visible and the situation around them is not.

Go into the conversation with that assumption and you will spend it defending your diagnosis rather than fixing the problem. The checklist above is a disciplined way to look at the situation first. It draws on the performance analysis approach set out by Robert Mager and Peter Pipe – work through the possible causes before you choose a remedy – rewritten for the way work is organised now.

Are there any legal implications to this performance issue? If it might touch on disciplinary or capability procedures, health, disability, discrimination, a protected disclosure or a probation decision, talk to your HR adviser before the conversation. How the first conversation is handled can matter later, and HR would rather hear from you early.

The six areas

AreaThe question underneathTypical fixes
Knowledge and skillCould they do it if their job depended on it?Practice, coaching, a job aid, retraining
StandardsDo they know what good looks like, and does everyone agree?Write the standard down; align everyone who gives instructions
MeasurementCan anyone, including them, see the gap?Measure results, objectively, and share the measure
FeedbackDo they hear how they are doing, soon enough and specifically enough?Regular, specific feedback tied to what they control
ConditionsDoes the job let them do it?Fix time, tools, information, authority and workload
Incentives and consequencesWhat happens to them when they do it well, and when they don’t?Remove hidden penalties; make good work count

The quickest test of all: could they do it if their job depended on it? If the honest answer is yes, this is not a skill problem and training will not fix it – look at standards, feedback, conditions and consequences. If the answer is no, ask whether they could ever do it. If they once could, they need practice and feedback. If they never could, they need to be shown.

Reading the result

The profile ranks the six areas by the share of your answers that point to a possible cause (a “No” counts fully, a “Not sure” half). Any area with at least one “No”, or two “Not sure” answers, is flagged, and the top one or two flagged areas are shown as the likely causes. Treat them as hypotheses to test with the person, not conclusions. Three things to take from it:

  • What to fix first. If the leading cause is in the job – standards, measurement, feedback, conditions – fix that before you discuss their performance. Holding someone to a standard nobody wrote down feels unfair because it is.
  • What is within their control. Skill sits partly with the person, and so does the motivation side of incentives – but the consequences that drive incentives are yours to change. Everything else sits mainly with you or the organisation. Be clear in your own mind which is which before you walk in.
  • Who else needs to be involved. Many causes belong to someone else: the owner of a system, a second manager giving conflicting instructions, whoever allocates work. A conversation with them may matter more than the one with your team member.

Then have the conversation, and bring the diagnosis in as a question rather than a verdict: “I’ve been looking at what might be getting in the way – here’s what I found. What have I missed?” Four steps to an effective tough conversation covers the preparation and the conversation itself.
