Coaching that outlasts the engagement

Coaching is unusually easy to feel good about and unusually hard to evaluate. The sessions are absorbing, the relationship is often the most candid one a leader has, and satisfaction scores are almost always high. None of that establishes that anything changed.

The question worth asking is narrower and less comfortable. Eighteen months after the engagement ended, what is different, and would anyone other than the coachee notice?

Set the answer before you start

Whether coaching produces a durable result is mostly decided before the first session, in how the engagement is framed. Three things are worth settling in writing.

• What specifically would be different if this worked, described as behaviour other people could observe rather than as a feeling.
• Who besides the coachee has a stake in the outcome, and what have they agreed to do differently.
• What happens to the work when the sessions stop.

The second is the one organizations most often skip, and it is the one that decides durability. A leader can change genuinely and completely, return to a system that rewards the old behaviour, and revert within a quarter. That is not a coaching failure. It is a sponsorship failure, and it was predictable from the start.

What durable change looks like

In our experience the changes that survive have a common shape. They are not new techniques the leader performs. They are decisions the leader now makes differently, embedded in things that outlast their attention.

• A meeting that no longer happens, or now happens with different people in it.
• A decision that has moved down a level and stayed there.
• A conversation the leader used to avoid and now has routinely, without preparation.

Each of these is visible to somebody else. That is the point. A change nobody but the coachee can detect is a change in self-report, and self-report is the weakest evidence available in this field.

Ending well

Engagements that end abruptly tend to fade fastest. The last few sessions are worth spending on what happens next: which support structures remain, what the leader will do when the pattern reasserts itself, and who will tell them when it does.

The aim is not a leader who depends on their coach. It is a leader who has internalized the questions well enough not to need one, which is the only outcome that is still working a year later.
