Applying Agility and Living Service Systems Thinking to Enterprise Architecture

Research Context

There are a number of well-known EA frameworks such as Zachman (1987), Federal Enterprise Architecture (CIO Council 2001), and The Open Group Architecture Framework (TOGAF) (Harrison 2011) that can be used for developing an adaptive EA capability of an enterprise. However, these frameworks are unlikely to be able to be used or adopted off-the-shelf for any specific organization. Organizations need to tailor their own situation-specific adaptive EA capability by integrating the necessary elements from different well-known EA frameworks (Bokang 2013). Adaptive EA capability needs to be tailored according to specific enterprise context and scope of the EA work (Harrison 2011). The challenge is how best to define the enterprise context and scope of the EA work? The AESS model is developed as a part of The Gill Framework for Adaptive Enterprise Service Systems (Gill 2013 - see Figure 1). The AESS model is intended to be used by organisations for defining an adaptive enterprise context and EA work scope for a specific situation.
