From successful to sustainable Lean production–the case of a Lean Prize Award Winner

Abstract

Many improvement programmes often fail to sustain over an extended period of time. Previous research suggests that a similar set of factors influence the success and sustainability of an improvement programme. The purpose of this paper is to make a distinction between the success and sustainability of improvement programmes, and to identify mechanisms that specifically contribute to the sustainability. In this paper, we study a sustainable improvement programme from the perspective of complexity theories that stress the importance of studying change as a dynamic process of interacting elements and events unfolding in time. We conducted a longitudinal, in-depth case study of a Swedish Lean Prize Award Winner where a Lean improvement programme was studied over 9 years. An improvement programme is successful if goals are achieved and the targeted problems are resolved. Furthermore, the first-order sustainability means the ability to sustain results and the second-order sustainability means the ability to keep an improvement programme alive. The lessons identified from complexity theories, such as destabilising the organisation, ensuring novelty and constant flow of change or self-organisation at the team level, are examples of mechanisms important to achieve the sustainability of the improvement programme.
