When someone isn't performing, the diagnosis races to the person — motivation, attitude, capability. It's the easiest explanation to reach for, and it's usually wrong. Far more often than not, what presents as a people problem turns out to be a system problem: something in how the work is set up, resourced, or rewarded. And the system is set up by the leader.
The order of the diagnosis is the method
In 1978, Thomas Gilbert published Human Competence: Engineering Worthy Performance — still one of the most useful things ever written about why people underperform at work. His central finding: the environment a person works in explains far more of their performance than anything about the person. The practical consequence is a diagnostic order. Check the conditions the system controls first, because they're the most common cause and the cheapest to fix. Only when those check out do you look at what the person brings.
Extended with a seventh lens for the dynamics that sit above any one team, the sequence runs like this:
- Clear expectations and feedback — does the person know, specifically, what good looks like, and do they hear how they're tracking against it?
- Tools and resources — do they have the equipment, information, authority and time the work actually requires?
- Consequences — does performing well lead anywhere? Does performing poorly cost anything? Or does the system reward everyone the same regardless?
- Skills and competency — can they do the work as it's actually defined?
- Capacity — do they have the physical, mental and emotional capacity for this role right now?
- Motives — do they want to do it?
- Team and organisational dynamics — is something above or around the team making good performance impossible from inside it?
The first three belong to you
Here is the part most leaders find uncomfortable: lenses one to three are set up by the system, which means they're set up by the leader. Expectations, resources and consequences are management's work. If performance is inadequate and you haven't verified those three, you may be the cause of the non-performance you're diagnosing.
Motives is the most over-diagnosed lens — it's the easiest to assert, because it lets the system off the hook.
"They're just not motivated" is a conclusion that requires nothing of the person reaching it. But a low read on motivation is very often a downstream symptom: of exhaustion (a capacity problem), of being unable to do the work as defined (a skills problem), of lacking the authority the role demands (a tools problem), or of never having been told what good looks like (an expectations problem). Diagnose in order, and most "motivation problems" dissolve before you reach lens six.
Why the order also saves you money
There's a second reason to work the lenses in sequence: cost. Clarifying expectations is nearly free. Fixing a resourcing gap is cheap. Adjusting consequences takes a conversation and some follow-through. Training — the reflexive fix for underperformance — is the expensive lens, and it only works when the problem actually lives there. Organisations that skip straight to a training program for what is really an expectations problem spend the most to fix the least.
The seventh lens can't be fixed from inside the team
Sometimes all six individual lenses check out and performance still lags. That's the signal to look at the seventh: dynamics between teams, functions or levels that no one inside the affected team can change. Conflicting KPIs between departments, a decision bottleneck two levels up, an unresolved turf issue. The trap here is complaint — the seventh lens only moves when someone takes a concrete proposal to a sponsor with the power to act on it.
The discipline, then, is simple to state and rare in practice: when performance disappoints, resist the story about the person until you've checked the system — in order, cheapest first.
