Potential Stack

The Potential Stack answers a question that skills frameworks leave open: at equal competence, what distinguishes two employees facing a new situation? The framework stacks six observable layers — learning capacity, absorption speed, contextual plasticity, appetite, execution reliability, contagion coefficient — that can be measured independently of the job performed.

The principle is simple: a skill is a snapshot; potential is a trajectory. As long as employees are evaluated on what they can do, organisations mechanically ignore what they can learn, and confuse the solidity of the stock with the velocity of the flow. The operational consequence is that organisations over-invest in their most visible experts and under-invest in their fastest learners — exactly the opposite of what the arrival of AI requires.

In practice, the Potential Stack is filled in through structured interviews, work simulations and weak signals drawn from day-to-day interactions. It feeds three decisions: where to place a high-leverage training effort, who to expose first to a new tool, and which employees to position on the critical links of a transformation. It does not replace skills evaluation; it precedes it.

One example: when deploying an HR copilot at a cooperative bank, six "high potentials" in the classical sense were planned as ambassadors. Reading them through the Potential Stack showed that three had high appetite but low contagion. The deployment was redirected; adoption time was halved.

The Potential Stack is not a proprietary method; it is a public grid that any HR director can adapt to their sector. Its value lies in usage discipline, not in tool sophistication.
