Performance effects of multiple control forms in a Lean organization: A quantitative case study in a systems fit approach

• We test the performance of a package of Lean control forms in a systems fit approach.
• Enhanced Lean improves non-financial performance, cost-efficiency, and profitability.
• The Lean control forms show balanced complementary effects.
• The latter found by supplementing the Euclidean distance with a city-block distance.

The primary objective of this paper is to research and test how control forms function and perform in a Lean organization. In the present quantitative case study, we provide statistical support that Lean is a set of multiple control forms (output, behavioral, and social controls) that complement each other to enhance performance, i.e., it is a control package. Therefore, performance is increased if the average level of control forms is increased, and performance is further increased if the control forms are balanced at the same level representing a complementary effect between them. Moreover, we provide a refinement to the statistical approach in testing systems fit models like ours by supplementing the Euclidian distance with the city-block distance. In this way, we are able to show that the control forms in Lean have a balanced complementary effect on performance, which is distinct from a solely additive effect or no effect. The refined understanding of complementary effect between control forms, the notion of balance, in a Lean organization can be utilized in understanding and testing more general control package theory in other contexts. Our data are archival data spanning multiple years in a dedicated Lean organization. This Scandinavian organization has around 2000 employees and produces small electronic components that are sold to business customers.
