Since, in practice, very few project business cases are verified after the fact, I also proposed a table of key benefits indicators to measure the EA value returns after the implementation of an iteration. The every day life solution delivery projects are integrated to the EA since the solution architecture recommended design has the same components as the EA directly updating it as such. In practice, many attempts at developing the EA have ignored the people and organization or have been limited to just aspects of an EA: IT architecture, SOA, or business process engineering.
There are numerous external and internal forces that lead towards the development of an Enterprise Architecture: • Business management need for direct control of change of the Enterprise, IT and investment process; for a long time now, business users have struggled to obtain the IT support they need to deliver process change for flexibility • The need for Enterprise simplification and integration of point solutions and silo organizations due to the current state of organic growth and patching • Increasing customer demand and expectations for quality, growing raw material and energy prices forcing companies to deliver new levels of scalability, quality, cost efficiency and performance • Rising worldwide business competition manifesting in o Rapidly reducing lifecycles/Time to Market o Increasing consolidation trend through mergers and acquisitions as the cost of developing new products in house is growing o Rising trend for outsourcing of Business Process (BPO) , applications (SaaS), data centers and managed services o increasing request for modular, service based business architecture (SOA) and growing popularity for web services to increase business agility • Drive for quality frameworks (Six Sigma, CMM) and new regulatory compliance (SOX, Basel II, HIPAA…) demanding documented and auditable structures and processes • EA, becoming a regulatory requirement in the US: the Clinger-Cohen Act of 1996 for Federal Agencies mandates the EA.
The functional architecture describes the Enterprise flows (workflows) as a sequence of processes in business functions. It is usually represented as swimlane or sequence chart diagrams. As a logical view, it serves as the baseline for the design of the current and target EA architecture. The Business Functions Map, while specific to a company, it is based on the generic Business Reference Model, valid for any Enterprise. An Enterprise is modeled both as a hierarchy of business functions (Business Functions Map) and flows (Business Flows Map).
