Abstract
The information system (IS) change management and governance, according to the best practices, are defined and described in several international methodologies, standards, and frameworks (ITIL, COBIT, ValIT etc.). These methodologies describe IS change management aspects from the viewpoint of their particular enterprise resource management area. The areas are mainly viewed in a partly isolated environment, and the integration of the existing methodologies is insufficient for providing unified and controlled methodological support for holistic IS change management. In this paper, an integrated change management methodology is introduced. The methodology consists of guidelines for IS change control by integrating the following significant resource management areas – information technology (IT) governance, change management and enterprise architecture (EA) change management. In addition, the methodology includes lists of controls applicable at different phases. The approach is based on re-use and fusion of principles used by related methodologies as well as on empirical observations about typical IS change management mistakes in enterprises.

Summary
Enterprise information systems (IS) are subject to frequent modification due to the continuous change of business requirements affected by internal and external factors. Each enterprise resource management area is governed separately, usually within different organisation units, and coordination and united oversight are insufficient. That includes several control aspects, for example, the reuse of existing public sector EA components to avoid development of parallel ICT solutions and the use of mandatory principles of “digital by default” and “digital only”. We propose the integrated application architecture change management methodology to address the aforementioned coordination and control problems. The methodology is designed for medium-size and large enterprises, including public sector organisations. It focuses on application architecture (AA) domain. The aim of the methodology is to provide support to the organisations in the controlled change management environment creation, integrating both IT and EA governance aspects.
