There is little doubt that strategic alignment has an important role to play in any organisation – as evidenced by the plethora of models available to assess alignment from various angles. Similarly the importance of Business Process Management (BPM) to organisations and organisational success continues to grow. However, little is known about what constitutes strategic alignment of BPM and how this might be measured. This paper addresses this gap by presenting the top 5 factors of strategic alignment of BPM (so called capability areas) as they have been identified during an international Delphi study. In addition, this paper reports on insights derived from existing literature and an in-depth case study undertaken to empirically explore these capability areas in more depth. The result is an operationalised view of the strategic alignment of BPM.
