When Training Is Not the Answer — Diagnosing Performance Gaps Correctly

1. The Five Causes of Performance Gaps; Only One of Which Training Addresses

Thomas Gilbert’s Behaviour Engineering Model, first published in 1978, identified six categories of performance barrier — environmental and individual — that produce performance gaps. The framework has been refined in various forms but its core insight remains: most performance problems are caused by factors in the work environment, not by individual knowledge or skill deficits. Training addresses knowledge and skill deficits. It cannot address the other categories.

Performance Gap Cause	Training Will Help?	Right Intervention
Employee does not know how to perform correctly	Yes; this is the training use case	Training designed to develop the specific knowledge or skill
Employee does not know what correct performance looks like (unclear expectations)	No; training how to do something undefined cannot help	Clarify the performance standard; set observable expectations; provide feedback on current performance
Employee lacks the tools, time, or access to perform correctly	No; training cannot provide missing resources	Process redesign, tool provision, resource allocation, manager advocacy
Manager models, rewards, or accepts the wrong behaviour	No; the trained behaviour will extinguish against the modelled behaviour	Manager coaching and accountability; manager behaviour change as the primary intervention
Employee knows how but the incentive structure rewards not doing it	No; training cannot change incentive structures	Performance management redesign; incentive alignment; consequence management

2. The Single Diagnostic Question That Separates Training from Non-Training Problems

Robert Mager and Peter Pipe’s diagnostic framework, most fully developed in their book “Analysing Performance Problems”; offers the simplest and most practically useful diagnostic question for distinguishing training from non-training problems.

1. If the answer is yes — they could perform correctly if their job depended on it — the gap is not a knowledge or skill deficit. Something in the environment is preventing correct performance: unclear expectations, missing tools, counter-productive incentives, or management behaviour that makes incorrect performance easier or more rewarded than correct performance. Training will not resolve any of these. The diagnosis points to a management, process, or environmental intervention.
2. If the answer is no — they genuinely could not perform correctly even if their job depended on it — training may be appropriate. But further diagnosis is needed: what specifically do they not know or cannot do? Is it knowledge of a procedure, operation of a system, judgement in a specific decision-making situation, or a skill that requires practice to develop? Each requires a different training design — and some may be better addressed through job aids, performance support, or on-the-job coaching than through a training programme.

3. Non-Training Interventions — What to Recommend When Training Is Not the Answer

1. Performance standards clarification and feedback. When the gap is caused by unclear expectations, the intervention is defining the standard in observable, specific terms and communicating it directly to the employee; with feedback on their current performance against that standard. This is a manager conversation, not a training module. An L&D function that can help a manager articulate the specific behaviour gap and the specific standard required is more valuable than one that converts unclear expectations into a generic training programme.
2. Job aids and performance support for infrequent tasks. When the gap is caused by low frequency of the task; employees do not perform it often enough to maintain reliable memory of the procedure, a job aid (a checklist, a quick reference guide, a step-by-step prompt accessible at the point of need) is more effective than training. Training the procedure once every year will not produce reliable performance for a task performed quarterly. A job aid that guides performance when the task occurs will.
3. Manager coaching and accountability for management behaviour problems. When the gap is caused by manager behaviour that models, rewards, or accepts incorrect performance, the intervention must reach the manager; not just the employees whose behaviour the manager is shaping. Manager coaching, manager accountability in performance objectives, and direct feedback from the manager’s own manager are the interventions that change management behaviour. Training the employees is addressing the symptom rather than the cause.

4. When L&D Should Push Back on a Training Commission

1. When the commission is driven by an event rather than a diagnosed gap. A training commission that arrives as “we had an incident, we need training” is responding to a symptom. Before designing the training, diagnose whether the incident was caused by a knowledge gap that training can address or by a process failure, a management failure, or a motivational factor that training will not fix. The training that follows an incident without this diagnosis typically addresses the wrong problem and fails to prevent recurrence.
2. When the commission cannot name a specific observable behaviour change. A training commission that cannot specify what people should be doing differently after the training; in observable, measurable terms, is a content delivery brief, not a performance improvement brief. Accepting and executing it without diagnosis produces a training programme that delivers content without addressing a specified performance gap.
3. When diagnosis reveals the root cause is management behaviour. The most commercially significant pushback L&D can deliver is the finding that the performance gap a business is asking training to fix is caused by the behaviour of the managers whose employees are the proposed training population. Naming this; and recommending manager coaching or accountability as the primary intervention, requires credibility, data, and courage. It is also the diagnosis that, when acted on, produces more lasting performance improvement than the training programme would have.

In Summary

The L&D function that accepts every training commission and delivers every training programme regardless of whether training will work is optimising for activity, not impact. The function that diagnoses performance gaps, identifies when training is and is not the right intervention, and recommends the appropriate response; training, job aid, process redesign, manager coaching, or expectation clarification, is operating as a performance partner rather than a content supplier.

The diagnosis that reveals training is not the answer is not a failed commission. It is the most valuable insight an L&D function can provide to a business that has been repeatedly investing training budget in problems that training alone cannot solve. The willingness to deliver that diagnosis; clearly, with data, and with a recommendation for what will work, is what distinguishes strategic L&D from reactive training delivery.
