The research is based on a multiple case study of five manufacturing firms. It is concluded that the APS implementation focus and APS use impact three effect types differently if applying a process or system focus and more positively if applying an APS lead, compared to lag, approach. It also shows that the organisation, individuals, technology impact the effects, no matter APS implementation focus.

However, empirical evidence showing that sophisticated methods are better than simpler ones remains scarce, and companies have reported difficulties with using sophisticated planning methods. In this study, we therefore investigate how sophisticated MPS methods impact three perception-based performance variables—namely, plan feasibility, inventory turnover rate, and delivery service—while accounting for the complexities of planning environments and MPS maturity. We define six MPS methods, ranging from those that ignore capacity to those exhibiting capacity-constrained planning using optimisation. An analysis of survey data from a sample of Swedish manufacturing companies reveals a significant negative effect of less sophisticated methods compared to highly sophisticated ones in terms of plan feasibility, as well as a significant negative effect of the simplest method in considering available capacity compared to highly sophisticated methods in terms of delivery service. The maturity of the MPS process most significantly impacts all performance measures, whereas planning environment complexity shows only a weak negative impact. Findings also indicate that both MPS process maturity and sophisticated MPS methods mediate the negative performance prompted by complex planning environments. Results thus suggest that sophisticated MPS may generally affect performance both directly and indirectly. Using sophisticated MPS methods reduces the negative effects of complex planning environments and results in more feasible plans irrespective of environment complexity and process maturity.

It is a qualitative case study of two APS system-supported S&OP processes. The work aims to generate propositions concerning the relationships among the use of APS system, the context, ITO dimensions, and fulfillment of S&OP aims. Use of APS systems was especially appropriate in support of S&OP processes in complex planning environments and when S&OP aims were ambitious. ITO dimensions were important influences on successful APS system use in most contexts. APS systems were not considered appropriate when having S&OP processes with ambitious aims and low individual and organizational maturities. Use of APS systems was also inappropriate when the extent of technological maturity was minimal. S&OP processes with ambitious aims, operating within a complex planning environment, are difficult if not impossible to implement without the support of APS systems. The suggestions on when APS systems should be used in different S&OP environments will be useful to companies implementing or about to implement APS systems. APS systems offer great potential if they are effectively used to support S&OP, still the use of APS system in S&OP is unexplored. The paper shows how the context and the ITO dimensions affect the successful use of APS systems in S&OP processes

It describes how the PM process of on-time delivery is managed in manufacturing companies and compares the integration and management issues of on-time delivery between companies with high and low perceived on-time delivery performance. Analysis is based on a survey study of Swedish manufacturing companies in 10 industrial sectors. The focus is on on-time delivery from the respondents'most important supplier. The PM activities defining metrics, target setting, measurement and analysis are not highly integrated between customers and suppliers when measuring on-time delivery. This is especially true for measurement activity, which is the activity with most issues to manage and integrate. The PM issues most significantly related to high on-time delivery performance were automated data collection, registration and report generation.
