The industrial development together with the globalization has led to that the markets are changing which in turn has led to an increased complexity of the organizational structures. Therefore, in order for firms to manage the customer’s expectations they need to develop their production planning. Although production planning and control is a mature area within research, there is a gap of knowledge regarding ways of planning the production operationally. Previous research within the area has mostly covered manufacturing issues through simulations and mathematical models, while the production planning and control structure has briefly been discussed on a more general level. This study addresses this through extending the knowledge on ways of planning the production operationally. Thus, the purpose of the research is to gain a deeper understanding for different ways of planning the production together with their implications. A case study was conducted at a Swedish high-tech make-to-order manufacturing firm characterized by low volume and high variety production, and the data was collected through interviews, observations and internal documents. This resulted in different ways of planning the production and their implications, which is divided into organizing planners and the planning process. The main empirical contributions of this research are summarized as: 1. Insight to current ways of planning through mapping the existing organization of planners and planning processes. 2. Implications with the different ways of working. 3. Understanding for what is suitable for the organization based on the implications, together with recommended actions on how to adapt. The study covers initial findings within the field, however, they should be seen as a foundation for future research as well as when taking decisions regarding areas covered within this research.
