EA Modelling Guidelines From Capabilities to Services Version 2.5

Strategic Direction The HA’s strategy is to move away from purchasing “islands of technology” to the procurement of modular, loosely-coupled, managed services.

11/17/2018 12:49 AM Capability Mapping Capability mapping is a modelling method for determining the strategic positioning of an organisation. Based on the theory of Porter, Capability Mapping is used to understand the implications of a strategy by viewing it in terms of capability systems. Capability Mapping uses activity-system maps for the visual representation of the model. Capabilities should be described by a name and quality characteristics like necessary people, technology, process, management and information.

How the Capability view differs from other Business Architecture views 11/17/2018 12:49 AM Roots of contemporary performance problems are due to organisationally based operating model Process models (though an improvement) are not the optimal view or management layer, and they expose “how” business is done Capabilities manage “what service at what service level” – which is the most stable and concise level for design and management From Traditional Organisational Management To Process Optimisation To Capability Management

Separation of Concerns 11/17/2018 12:49 AM Separation of Concerns By separating “what” is done in an organisation, at both high and detailed levels, from “how” it is done, in terms of people, processes, ICT and other views, an inherently more stable and objective view of the business and the organisation is exposed.

What is a Capability?

Definition of a Capability 11/17/2018 12:49 AM Definition of a Capability The practical ability to realise business benefit by a combination of Processes, Organisation, Technology & Information.

Capability Mapping can provide much more relevant information 11/17/2018 12:49 AM Capability Mapping can provide much more relevant information Metrics – how is it measured? Cost data? Service level (like a service level agreement with outsourcing) – how it is and how it should perform? Compliance and governance regulations? Owner? Customer? Does it directly contribute to the performance of the parent capability or the overall organisation (core capability)? Is this capability a key part of what external organisations such as customers think of when they do business with the organisation (identity/brand) ?
