Problems in the onward and upward phase of APS system implementation: Why do they occur?
Artikel i vetenskaplig tidskrift, 2011

Studies conducted on advanced planning and scheduling (APS) systems have found problems in the marginal or negative returns from APS systems when they are implemented in manufacturing planning and control processes. The purpose of this study is to examine what problems exist in the onward and upward phase of the APS system implementation and how the individual, technical and organizational (ITO) dimensions in the implementation phases influence the problems in the onward and upward phase. Three different manufacturing companies using a supply chain planning module to support their tactical manufacturing planning processes were chosen and their APS system implementation phases were studied. Interviews with the project members and the end-users, and on-site visits, were conducted. Internal company data and presentations were collected and analyzed according to four implementation phases and the ITO dimensions. Three types of problems were identified in the onward and upward phase: process-related problems concerning difficulties to move forward; dependency on a consultancy firm; and too much time spent in the system. System-related problems include the usage of parallel systems and inadequate usage of the appropriate potential of the APS system. Plan-related problems regard an incorrect production plan. Different relationships between the ITO dimensions in the implementation process and the problem type were proposed. The relationships identified in this paper are of important knowledge for companies who are implementing, or are in the process of implementing, APS systems. There has been little written about the implementation issues of APS systems. The practical use of APS systems in the tactical planning is also relatively low. It is not known what problems to expect and how the ITO dimensions influence the problems during implementation. The findings this paper discusses fill some of these gaps.
