The Capability® Module focus on the technical and hands-on approach. ITIL Capability Modules are more process oriented and provide a deep understanding of the ITIL processes and functions, how they are applied and how they act together.
The Capability Modules focused on role-based clusters in a modular set, each with a qualification. Each cluster contains groupings of processes and roles from within IT Service Management, intended to offer candidates a balanced knowledge of ITIL practices which have direct interaction and dependencies in their daily use.
In general, the modules in Capability are most useful to those who take part, or want to take part, in the day-to-day practical activities described within each of the processes.
