Learning curves are longest where retirements come first

Placeholder. This article is placeholder copy written to test layout and tone. It is not published research and makes no factual claims.

Some roles are learned in months; others, such as electrical and instrument technicians or the engineers who tune a process, can take far longer. This piece argues that the roles with the longest learning curves deserve their own succession plan.

Measure time to competence

Time to competence runs from hire to working unsupervised on the full task set. Measured that way, it includes the months of shadowing that never appear in a training record.

Callout 1: Jaws: a new technician learns how to measure; an experienced one knows where.
Callout 2: Vernier scale: reading to the next division takes practice, not a procedure.
Callout 3: Thumb wheel: the right pressure is learned by feel.

Focus where the curve is longest

Leaders do not need to shorten every learning curve. They need to start the longest ones early enough. The exhibit uses illustrative values to show how the comparison will be presented.
