A capacity model for change: how much load the organisation can carry, and where it is already spent.
Every transformation plan implicitly assumes free capacity: executive attention, middle-management change capacity, front-line absorption. In the cohort data, the median organisation begins its programme with the middle layer already committed to 118% of available capacity. The plan is drawing on an overdrawn account, and the overdraft is discovered at month nine, as slippage.
The Load Map treats change capacity the way an engineer treats structural load: rated limits per layer, current utilisation measured rather than assumed, and headroom that must exist before new load is added. It converts “can we do this?” from a judgement call into arithmetic, and the arithmetic is only ever as honest as the load measurement underneath it, which is the thing clients hand over least complete.
Rate the limits for each layer in turn, executive, middle and front line, where a rating is how much concurrent change that layer can absorb, benchmarked against the cohort by size and sector.
Week 1–2Measure current load from evidence: initiative registers, calendars, spans, absence data. Everything in flight is on the map, including the initiatives nobody admits to.
Week 2–4Sequence against headroom. Initiatives queue until capacity exists, and the stop list is maintained as carefully as the commitment list.
Week 4+The map is re-measured at every monthly resource forum. Load is a moving number, and the model is only as good as its last reading. The rated limits are benchmarks rather than laws of physics. A rating drawn from the cohort describes firms like the client rather than the client, so where an organisation sits at the edge of the cohort by size or by sector we treat its rating as a starting hypothesis and correct it at the first monthly reading.
Portfolio planning, to size drawn phases in Draw · Hold · Release against measured rather than assumed capacity.
Programme rescue, to establish how much of a stalled portfolio the organisation can actually carry, and what has to stop before the rest of it moves.
Annual planning, as the arithmetic behind the uncomfortable conversation about how much of the wish list is fundable in attention, not money.
Derived from the cohort study and applied in more than thirty-five engagements since 2024. The second figure compares programmes rather than running a controlled trial, and sequencing is never the only thing that differs between them:
The Institute stewards the model and revises it after every tenth application review. The rating benchmarks are re-based annually against the cohort, which means a rating quoted from an earlier edition will not always match the current one. Where they differ, the newer reading wins.
