Although benefits are promising, many companies face problems leveraging synergies between Lean and Digitalization at the program management level. This paper aims to identify activities to manage the boundaries of Lean and Digitalization programs.
The research design follows a cross-industry multiple-case study approach. A total of 14 interviews were conducted with Lean and Digitalization experts from 10 companies. Interview quotes were mapped on a pre-defined list of descriptive codes and iteratively merged and excluded.
We identified 12 activities by which companies manage the boundaries of their Lean and Digitalization programs. Three distinct boundary management approaches could be identified: collaborative, configurational, and competitive. A collaborative approach fosters governance, the belief in synergies, and the development of combined artifacts. A configurational approach creates combined responsibilities, assesses areas of collaboration, and fosters interaction across the organization. A competitive approach creates unclear responsibilities and exchange, perceives no added value in integration and follows separated implementation of Lean and Digitalization programs.
This study sheds light on the boundaries of Lean and Digitalization programs and identifies activities to manage them. We derive propositions for the Lean and Digitalization program management. Moreover, this study positions itself at the forefront of research investigating how integration of Lean and Digitalization actually occurs or does not occur.
