A Synthesis of Enterprise Architecture Effectiveness Constructs

Companies throughout the world use Enterprise Architecture (EA) because of benefits such as the alignment of business to Information Technology (IT), centralisation of decision making and cost reductions due to standardisation of business processes and business systems. Even though EA offers organisational benefits, EA projects are reported as being costly, time consuming and require tremendous effort. Companies therefore seek to ascertain ways to measure the effectiveness of EA implementation because of the money and time being spent on EA projects. EA Effectiveness refers to the degree in which EA helps to achieve the collective goals of the organisation and its measurement depends on a list of constructs that can be used to measure the effectiveness of EA implementation. Currently, there exist no comprehensive list of constructs that are suitable to measure the effectiveness of EA implementation. The paper reports on the results of a study that explored the development of a compreh ensive list of constructs suitable for measuring the effectiveness of EA implementation. The artefact developed in this research study is called Enterprise Architecture Effectiveness Constructs (EAEC). The EAEC consists of 6 constructs namely: – alignment
