All organisations have to keep improving different aspects of their business in order to survive in their business area. This improvement can be done in different ways, including as business and IT alignment. There exist different ways of performing business and IT alignment, such as applying EMMs. Enterprise Modelling (EM) is an area that has been built up with the intention of improving business practice and management. An Enterprise Modelling Method (EMM) is a systematic way of building models that are to be used for planning improvements. For this purpose, it is needed to make an evaluation of methods capabilities in supporting business and IT alignment. According to all above, the results of this paper include a list of EMMs that are applicable in business and IT alignment.

Abstract. Each organization should make progress to remain competent in its business. Enterprise Modeling (EM) helps in understanding the current and planning the future states, followed by proposing improvement actions in an enterprise. To receive support from EM, we should start a process of using an Enterprise Modeling Method (EMM), that likewise any other process needs using resources. As resources are expensive, we prefer not only gaining results, rather using resources reasonably, i.e. performing an efficient process that supports the process quality. To realize if we have an efficient EMM, we should evaluate its efficiency. In this paper we present a method for efficiency evaluation of EMMs for general case of application. This method contains efficiency criteria and questions for evaluating their fulfillment. Then it is applied to the Enterprise Knowledge Development for appraising the evaluation method. The paper ends with a number of conclusions about the evaluation method.
