The book aims to measure and evaluate the use/success of operational budgeting in Polish companies and to identify and measure the determinants of success, based on the suggested model. It focuses mainly on: (a) the role of operational budgeting in the process of managing a company, (b) the variables that influence how the use/success of operational budgeting is assessed, to present factors that determine individual variables, and to identify the relationships and links between them, and (c) a model that helps to measure and evaluate the use/success of operational budgeting. This book tries to fill the knowledge gap on the quality and benefits that arise from well-designed Operational Budgeting Systems. To get benefits, it is necessary to assess the current budget system. With that, the author reduces ambiguity about assessing the use of operational budgeting. The author limits her approach to the production sector and Poland. Still, I believe this approach can be expanded across the sectors and countries. Therefore, I see a relevant contribution in practice. Also, it opens the way and shows directions to diagnosing and improving firms’ Operational Budgeting Systems. This publication is commendable; it puts traditional budgeting – which has been highly criticized into context and presents its value, role, and its contribution in a Control System. In response to those criticisms, the author points to the quality aspect of operational budgeting, showing its usefulness to users and organizations.
