The accounting world is confronted with criticism on the relevance of its practices. This has led to improved allocation methods and improved methods for operational decision making. Until now few attempts are made to integrate these new accounting methods. This paper presents an integrated accounting information framework to measure the economic consequences of manufacturing improvement decisions. The notions "resource consumption" and "resource spending" are connected to build the framework. Within this context effectiveness, efficiency and productivity improvement are redefined. A project portfolio gives operations management the possibility to rank improvement projects based on magnitude, timing and economic results.
