Abstract

A strategy map is a diagram that describes how an organization creates value by linking improvement of performance measures to strategic objectives through explicit hypothetical causal relations. To validate these relations, an enhanced control chart method applied to relevant databases of the organization, has been developed. The method identifies significant performance improvements by means of CUSUM control charts, uses binary variables to mark them and time bounded search cycles as dictated by the causality constraints. When appropriate, the fuzzy set theory is utilized for merging local performances measured on different scales/units and for avoiding subjectivity related to the interpretation of the measured results. Analysis of a test case shows that the proposed method succeeded to validate all the hypothetical causal linkages on the strategy map, for which data were available. A (global) fuzzy measure of the main manufacturing process, merging several relevant local manufacturing measures proved useful in the validation procedure.
