Especially in the field of software engineering many tools (A4 Tool, CAME, [[ARIS]]), [[computer languages|languages]] (ACME, Rapide, [[Unified Modeling Language|UML]]) and methods ([[Dynamic Systems Development Method|DSDM]], [[RUP]], [[ISPL]]) are developed and extensively used. Also, the transition between the software engineers (step 3) and computer programmers (step 4) is already highly formalized by, for instance, [[object-oriented]] development.
Setting strategic objectives (step 1) and the corresponding search for [[business]] opportunities and weaknesses is a subject extensively discussed and investigated for more than a hundred years. Concepts like [[Business process reengineering]], [[Product software market analysis]], [[Requirements analysis]] are commonly known and extensively used in this context. These strategic inputs must be used for the development of a good enterprise design (step 2), which can then be used for software design and implementation respectively.
Recent studies have shown that these enterprise architectures can be developed by a number of different methods and techniques. Before these methods and techniques are discussed in detail a definition of an [[Enterprise architecture]] is given:
