The case for intensity
There is a straightforward and well-evidenced case for concentrated, intensive attention as a performance lever. Nelson Repenning and John Sterman’s research at MIT Sloan, published in California Management Review, documents cases where a genuine and substantial performance gain followed a period of intensified oversight — a senior manager reviewing work more closely, catching issues that would otherwise have compounded, and visibly signalling that a particular standard mattered. In the short term, this kind of intensity is not merely a placebo; it produces real, measurable improvement, and dismissing it as inherently superficial would be inconsistent with what their case studies actually show.
The strongest version of the case for intensity treats it as a deliberate, temporary intervention rather than a permanent operating mode — a way of surfacing and correcting a specific, acute problem quickly, with the explicit expectation that the underlying work will need a separate, more durable mechanism once the intense period ends.
The case for consistency
The case for consistency draws on the same research from a different angle. Repenning and Sterman’s central finding — the “capability trap” — is specifically that gains produced through intensity alone tend not to persist once the intensity ends, because the intensive period rarely changes the underlying conditions that will operate once attention moves elsewhere. Their broader argument, that organisations under pressure default to “working harder” rather than “working smarter,” is in effect an argument for consistency: a change built into how the work operates by default, requiring no ongoing intensive attention to sustain, is more durable than a gain propped up by a period of heightened focus.
Steven Kerr’s research on reward systems adds a further, independent argument for consistency specifically. His finding — that people respond to what is actually and consistently rewarded, not to a temporary signal of what currently matters — suggests that an intensive period, however well-intentioned, sends a different and potentially confusing signal than a consistently applied standard does. A team that experiences performance management as a series of intense pushes interspersed with quieter periods may reasonably learn that the real standard is whatever gets enforced loudly and intermittently, rather than internalising a steady baseline expectation — which is a different, and arguably less durable, behavioural outcome than the one a consistent approach would produce.
Why the disagreement persists
The disagreement persists partly because intensity and consistency are not actually opposites in every sense, and partly because they are measured on different timescales in the available research. Intensity’s evidence base is strongest in the short term — the specific period during which additional attention is applied — where the effect is clear and well documented. Consistency’s evidence base is strongest over the longer term, addressing what happens after any period of intensity ends, which is precisely the question intensity-focused research is less equipped to answer on its own. A study designed to measure a short-term intervention will tend to find intensity effective; a study designed to measure durability over a longer horizon will tend to find that durability depends on something closer to consistency. Neither design is wrong; they are simply answering different questions, which makes a straightforward comparison of “which works better” harder to settle than it first appears.
A further source of disagreement is that the two postures can, in practice, be combined rather than substituted for each other — a genuinely intensive period used deliberately to establish a new standard, followed by a consistent, lower-intensity mechanism designed to sustain it. The research reviewed here does not fully resolve whether this combination reliably captures the benefits of both, or whether the transition from intensity to consistency is itself a point where gains are most likely to be lost, which remains a genuinely open question rather than a settled one.
There is also a measurement-level reason the two postures are hard to compare cleanly: intensity produces an effect that is easy to attribute, because it coincides with a specific, dateable period of extra attention, while consistency produces an effect that is diffuse and cumulative, harder to isolate from everything else happening in an organisation over the same stretch of time. This asymmetry in how observable each effect is may itself bias which posture gets credited in retrospect — an intensive push that precedes a visible improvement is an easy story to tell afterward, while a steady, consistent standard that prevented a decline nobody can point to is a much harder case to make, even where the underlying research suggests it may be doing at least as much of the real work.
A related consideration, distinct from the direct evidence for either posture, involves what each communicates to the people being managed. An intensive period, however well designed, is difficult to disguise as anything other than unusual scrutiny, and unusual scrutiny tends to be read, correctly or not, as a signal that something has gone wrong. A consistent standard, applied evenly over time, carries a different and arguably less fraught signal — this is simply how performance is managed here, rather than a response to a specific failure. Neither signal is inherently better, but a leadership team choosing between the two postures is not choosing only a measurement strategy; it is also choosing what message the choice itself sends to the people who will experience it.
There is also a resourcing dimension that neither body of research addresses directly but that follows reasonably from both: intensity, by definition, is not something an organisation can sustain indefinitely across every area of performance at once, because it depends on a finite and valuable resource — senior attention — being concentrated somewhere in particular. Consistency, by contrast, scales differently: a standard, once genuinely embedded rather than actively enforced, requires comparatively little ongoing senior attention to maintain. This practical asymmetry may be part of why organisations default to intensity more often than the evidence on durability would strictly recommend — it is the posture available at short notice, using resources already at hand, while building genuine consistency typically requires a longer lead time that a leadership team under immediate pressure to show a result does not always feel it has.
What it means for a leader
Should a leadership team ever use a period of intensified oversight? The evidence does not argue against it — a well-targeted intensive period can produce real, measurable improvement. The caution the research raises is specifically about relying on intensity alone, without a plan for what replaces it once the intensive period necessarily ends.
Is a consistent approach always preferable to an intensive one? Not unconditionally — the two postures answer different questions on different timescales, and treating consistency as universally superior would overstate what the research on durability actually shows about the value of short-term intensive correction.
How would a leadership team know if a gain from an intensive period is likely to hold? One relevant question, drawn from the research on the capability trap, is whether the intensive period changed something durable about how the work operates by default, or whether the gain depends on the same level of attention continuing indefinitely.
For how this pattern presents in other kinds of organisation, see other sectors.
Questions worth considering
- When the last period of intensified oversight ended, did anything about how the work operates by default change, or did the gain depend on the same attention continuing?
- What standard do people in the organisation believe is actually applied — the steady one, or whichever is enforced loudly and occasionally?
- What would a consistent baseline need to look like for a team under pressure to adopt it?
