Information quality for PPC: analysis of influence factors and diagnosis method proposal

Abstract

One of the most important problems that companies have to face for Production Planning and Control (PPC) is the lack of Information Quality (IQ) to support the decision making process. In this context, determining which factors affect the IQ necessary for PPC is a key issue. This paper presents a case study that analyzes the main influence factors on IQ. Furthermore, this paper proposes a method to perform diagnosis about these influence factors in companies. To analyze the IQ influence factors, a classification based on the sociotechnical approach was used and a set of matrixes that relate the IQ influence factors with the different functional areas that support the PPC were proposed. Results enable to identify which are the main factors and the functional areas and processes that can be improved to increase the IQ for PPC. This paper presents also practical results that show how to drive an IQ diagnosis.
