Meeting your target and being within the Green Range are not the same thing—and confusing the two can hide real management problems.

It’s common for managers to look at the dashboard, see that the monthly target wasn’t achieved, and conclude that something went wrong. But the opposite is just as common: the target was met—or even exceeded—and the status indicator turns blue, signaling performance above the expected level. However, that result may still fall outside the Green Range, meaning it lies outside the process’s normal operating range.

In this situation, no one stops to investigate because the immediate assumption is, “That’s great.” In reality, it could be a one-time anomaly, an event that is unlikely to happen again, or a sign that the process itself is changing and needs to be understood.

Both scenarios lead to poor decisions when we confuse two concepts that may seem similar but answer very different questions: the Green Range and the Target.

 

Two Different Questions About the Same Result

Every process produces results, and every result varies—that’s inevitable. The goal isn’t to eliminate variation, but to understand whether it’s expected or whether it signals a real problem. That’s where these two concepts come into play.

Green Range — The Voice of the Process

The Green Range represents your process’s normal behavior based on its historical performance. In other words, it reflects what your process typically delivers. If this month’s result falls within the Green Range, the process is behaving as it always has—for better or for worse.

Target — The Voice of the Customer

The Target represents the performance you want to achieve—the level that meets the actual needs of the business or your customers. Unlike the Green Range, the Target is not based on historical performance. It’s based on what is strategically required.

Here’s the key point: a process can be operating perfectly within the Green Range and still be far from achieving its Target. That’s not a system failure—it’s a clear sign that the process, as it’s currently designed, is no longer capable of delivering what the business needs.

Why This Confusion Is Dangerous

When managers treat “hitting the target” and “being in the Green Range” as if they mean the same thing, two common mistakes occur.

Celebrating Results That Shouldn’t Be Celebrated

The target was achieved in a single month, but the process is operating outside its historical pattern. That may indicate a one-time event rather than a genuine, sustainable improvement.

Treating Normal Variation as a Crisis

The result fell short of the target but remained within the Green Range. In other words, the process is behaving exactly as it always has. The problem isn’t this month’s execution—it’s the process itself. The right response isn’t a quick fix; it’s to rethink the process standard.

Both mistakes lead to disproportionate reactions: solving problems that don’t exist while overlooking the ones that truly require attention.

How to Interpret Results Correctly: FCA and Action Plans

The methodology behind the Green Range and the Target provides clear guidance on what actions to take, and each serves a different purpose.

Results Outside the Green Range → FCA (Fact, Cause, Action)

When a process operates outside its normal pattern, the priority is investigation. FCA exists for exactly that purpose: identify the fact, trace the chain of causes to the root cause, and define actions that bring the process back to its expected level of performance.

It’s important to remember that an action can either address the effect—providing a temporary solution to the symptom—or address the cause, changing the process standard to prevent the problem from happening again.

Target Not Achieved (Even When the Process Is Within the Green Range) → Action Plan

If the process is stable but that level of performance is no longer enough to meet business expectations, the answer isn’t to correct an abnormality—it’s to improve the process itself.

That requires a structured Action Plan, with initiatives designed to increase the process’s capability and move it to a higher level of performance.

Recognizing which of these situations you’re facing is the first step toward making informed decisions instead of simply reacting.

Practical Tip

Before reacting to any monthly result, ask yourself two separate questions:

  • “Is this result within my process’s historical performance?”
  • “Is this level of performance enough to meet the business’s needs?”

The answers are rarely the same—and the gap between them often provides the most valuable management insight.

What Changes When You Look at Your Indicators Through This Lens

Understanding the difference between the Green Range and the Target isn’t just a technical detail—it’s what ensures that your management decisions are proportional to the real problem.

Processes operating outside their normal pattern require root cause investigation. Stable processes that still fail to achieve the Target require structural improvement. Confusing these two situations wastes time, drains energy, and often leads to actions that solve nothing.

The next time you see a red or yellow status indicator, pause for a moment before taking action. Ask yourself: Are you looking at an abnormal process, or at a stable process that is no longer capable of supporting your strategy?

The right decision starts with answering that question.
