LinkedIn's 2026 talent research confirms a trend that has been building across three years: internal mobility rates are increasing across almost every sector, and organisations are investing more deliberately in internal hiring than at any point since 2020.

HR.com's 2025 Talent Mobility study puts internal mobility as a top-three talent priority for the large majority of organisations surveyed. The investment is real.

What is almost entirely absent: the connection between those internal moves and succession planning. Organisations are building internal mobility programmes to retain people and fill open roles. The intelligence those moves generate — about readiness, adaptability, and leadership potential under unfamiliar pressure — is rarely making it into a succession conversation.

Here is a pattern I see in nearly every talent function I work with.

The organisation has a succession grid. Names on a page, readiness ratings assigned, calibration session completed. And separately: an internal mobility programme. Roles posted, transfers processed, manager recommendations acted on.

Two processes. Zero connection.

That disconnect has three specific consequences.

Internal moves are managed as retention plays, not succession tests. When a high-potential wants to transfer to another function, the talent conversation almost always frames it as a retention risk to be resolved. The succession conversation asks something harder: what does this move reveal about their readiness? Can they deliver without their home-team support structure? Do they lead differently under unfamiliar pressure? These questions are rarely asked — because they belong to a conversation that isn't happening.

Succession grids are populated from calibration rooms, not from observed performance in stretch conditions. A candidate rated "succession-ready" by a well-disposed line manager in a comfortable calibration session is a very different signal to a candidate whose mobility history shows consistent delivery across functions, through transitions, in environments they had to build from scratch. The second candidate has evidence. The first has a rating. Most succession grids cannot tell the difference.

The data that would differentiate them is already in your HRIS. Every internal move is logged. Tenure in role, performance trajectory pre- and post-transfer, speed of adaptation, retention after the move. Almost no organisation connects this data to their succession model. The intelligence layer is absent — not because the data doesn't exist, but because no-one has assembled it.

When I build the intelligence layer for a client, mobility history is one of the first signals I like to pull. It surfaces something calibration sessions almost never catch: who has already been tested under conditions that matter, and who looks ready on paper but has only ever been observed in one environment.

The succession bench looks very different when you read mobility data alongside readiness ratings. It almost always surfaces at least one candidate the calibration process underrated — and at least one it overrated.

When I'm working with a client on succession calibration, I use the TMAP (Talent Mapping, Alignment and Positioning) Calibration Framework to bring three datasets into the same conversation: succession readiness rating from the formal calibration; performance trajectory over the last two to three years; and internal mobility history — moves made, cross-functional exposure, stretch assignments taken, and how performance responded to each transition.

The combination changes the conversation. Candidates who look ready on the grid but have never operated outside their home environment look very different to candidates whose mobility history shows consistent delivery across functions and conditions. One is succession-ready in theory. The other has evidence the calibration process has almost certainly underweighted.

Most organisations have the data. Almost none of them have assembled it this way. (totalia framework) → https://www.totalia.ai

How many of your current succession nominees have been tested in a different function, under pressure, outside their home team — and how many of them haven't?

When your team last processed an internal transfer, did anyone ask what that move would reveal about that person's succession readiness?
