Accounting Control, Operational Control, and the Value of Continuous Improvement: A Capacity Change Perspective

Abstract

This study examines challenges to the retrospective financial evaluation of continuous improvement (CI) activities. Through a review of the literature and active engagement with CI implementations, we identify several issues that may lead to divergence between operational and financial assessments. Out of this conflict emerges a set of concepts that we find important − the delineation of soft versus hard capacity benefits, the distinction between capacity used and capacity paid for, and the data gaps that relate to these benefits – and recognize operational improvement and financial improvement as distinct, yet interrelated, theoretical constructs. This study helps explain a series of persistent gaps in the management accounting literature: Conflict between operations and accounting managers, the divergent perspectives of Johnson and Kaplan after their publication of Relevance Lost (Johnson & Kaplan, 1987), and the need for both operational control (including detailed capacity control) and accounting control in CI firms. Instead of one control system being at odds with the other, or co-existing despite each other, each of these systems support a different component of the financial improvement process. Operational control systems in CI firms emphasize non-financial information and social and behavioral controls that empower decision-making by employees, while accounting control systems seek to motivate and translate operational gains into financial gains. Soft and hard benefits linked to capacity play an integral role in understanding the difference in focus of each control system, while data limitations help to explain why these systems remain loosely coupled in practice (or absent, as seems to be the case with detailed Capacity Management Systems).
