Capability Heat Map
A capability map coloured by a chosen dimension — maturity, cost, risk, or strategic importance — to make patterns visible to non-technical stakeholders.
The capability map's practical value is as a canvas that different overlays can be projected onto. The same structure, coloured differently, answers different questions and reaches different audiences.
Useful overlays: maturity, showing where performance is weak; strategic importance, showing where the business intends to differentiate; cost, which frequently reveals that most spend sits on undifferentiated capabilities; application count, where a capability supported by nine systems is a rationalisation candidate; risk, including single points of failure and unsupported technology; and change activity, showing where the organisation is actually investing effort — which often does not match the stated strategy.
The overlay comparison is where the insight is. High strategic importance with low maturity and low change activity is a strategy the organisation is not executing. High cost on low importance is misallocated investment. Both are visible in seconds on a heat map and invisible in a spreadsheet.
Two practical constraints: keep the map to two or three levels of depth, since deeper models are built once and never used; and name capabilities as what the business does, not as departments, or the map becomes an org chart and inherits every reorganisation.
