In lean thinking, which statement best captures the relation of stability?

• A. Stability is foundational and capability accounts for targets.
• B. Stability guarantees capability.
• C. Stability is irrelevant to capability.
• D. Stability and capability are the same.

Answer: (A)

In lean thinking, you must have a stable, predictable process before you can judge whether it can meet targets. Stability creates a dependable base where performance is in control and variation is minimized. Only from that stable footing can you meaningfully assess capability, which describes how well the process can hit the required targets given its remaining variation. So the idea that stability is foundational and capability accounts for targets captures this sequence: first stabilize, then evaluate whether the stabilized process can meet the goals. If a process is stable but its average performance is off-target or its spread is too wide, capability may still be poor, showing that stability alone isn’t a guarantee of meeting targets. Stability isn’t irrelevant to capability, nor are they the same thing; capability depends on the process being stable while also considering how much its output can meet the specified targets.
