Recap
Another shift tends to follow, this time, it is not just how KPIs are discussed - it's how they begin to shape behaviour.
What were originally designed as measures of performance start to influence how that performance is created, often in ways that were not anticipated. On the surface, results may still look positive. But about the outcomes begins to feel misaligned.
When Outcomes No Longer Reflect Intent
Most KPIs are introduced with clear intent. They are designed to focus attention, guide decision making, and align teams around what matters most. In the early stages, they often work exactly as expected, creating clarity and reinforcing the behaviours that drive performance.
Over time, however, the relationship between the KPI and the behaviour it influences can begin to shift.
>Teams respond to what is measured.
>They optimise for what is visible.
>The focus moves from achieving the underlying outcome to achieving the metric itself.
This is rarely a conscious decision, it is a natural response to how performance is defined and evaluated.
How Leaders First Notice the Shift
In most organisations, this change is not identified through the KPI itself. The numbers may continue to improve and targets may still be met, so ffectively, from a reporting perspective, everything appears to be working. The signal tends to appear elsewhere.
Leaders begin to notice outcomes that do not fully align with what the KPI was intended to drive. Progress in one area may create unintended pressure in another. Activity increases, but impact does not always follow in the same way. Results look strong on paper, but feel inconsistent in practice.
These moments are often difficult to articulate and there is often a sense that something is not quite right, without a clear explanation of why.
Why Good KPIs Can Lead to Unintended Behaviour
At Kestrel IQ, we often see this occur not because KPIs are poorly designed, but because they are effective. When a metric becomes closely linked to performance, attention, and accountability, it begins to shape behaviour more directly. Teams prioritise what is measured, sometimes at the expense of what is not.
As organisations grow, this effect becomes more pronounced.
>Metrics are used more consistently across teams
>Performance expectations become more visible
>Incentives and accountability structures become more closely tied to KPIs
Individually, these are positive developments.
Collectively, however, they increase the influence KPIs have on behaviour. Without regular recalibration, this can create subtle distortions, where the metric continues to move in the right direction, but the underlying outcome begins to drift.
When Optimisation Replaces Intent
This is the point where many organisations begin to feel the tension. Teams are not underperforming, they are optimising. But, they are optimising within the boundaries of how success is defined, rather than the broader intent behind it.
As a result:
>Effort can become concentrated on what is measured, rather than what matters most
>Trade-offs are made implicitly, rather than explicitly
>Short-term performance can be prioritised over longer-term outcomes
None of this reflects poor intent, it reflects how strongly KPIs shape behaviour when they are taken as the primary signal of success.
A Practical Starting Point
When outcomes begin to feel misaligned with intent, the goal is not to remove KPIs, but to understand how they are influencing behaviour in practice.
#1 - Observe where outcomes feel inconsistent
Look for areas where reported performance appears strong, but the broader outcome does not feel fully aligned. These moments often indicate that the metric is being achieved, but not necessarily in the way it was originally intended.
#2 - Notice what behaviour is being reinforced
Pay attention to how teams are responding to the KPI in day-to-day decisions. Behaviour will naturally align to what is measured, but that alignment may not always reflect the broader objective.
“What behaviours does this KPI encourage?”
#3 - Identify where optimisation is narrowing focus
Where teams are performing strongly against a KPI, consider whether that success is creating blind spots elsewhere. High performance in one metric can sometimes mask unintended trade-offs in another area.
“What are we optimising for here?”
These reflections do not undermine performance. They strengthen it, by ensuring that KPIs continue to support the outcomes they were originally designed to drive.
Understanding How KPIs Shape Behaviour
At Kestrel IQ, we work with leadership teams to understand whether KPIs are still reinforcing the behaviours they were designed to support, or whether they are beginning to shape outcomes in unintended ways.
Our Data to Revenue Diagnostic helps identify where metrics are influencing behaviour, where trade-offs are emerging, and where outcomes may be drifting from original intent. Understanding this early is often the difference between sustained performance and gradual misalignment.
In this article, we explored how KPIs can begin to shape behaviour in ways leaders did not intend, and how this often becomes visible through outcomes that feel misaligned.
In the next piece, we examine the point at which boards begin to move beyond KPIs alone, and what this shift reveals about how performance is being understood at the highest level.
Because one moment of clarity can change everything.
