“To develop a process-based management system at a textile company” is the title of this thesis.The thesis is a compulsory part of the master programme: Quality and environmental management at Högskolan i Borås, the master programme is worth 60 ECTS credits. It has been carried out as an interdisciplinary project between students of the School of Engineering as well as the Textile School in Borås.Almedahls is a textile company located in Kinna, Sweden. They are in a need of process-based management system for their four different strategic business areas and three companies.The purpose of the thesis is not only to develop a process-based management system for Almedahl-Kinna, which is one of the three companies, but also to create the new management system in order for it to work for all three parts of the company in the future.The theory used in this project focuses on the definition of business process mapping as well as its application in use. The theory also includes process-based management systems, business process management and measurements.The theory and interviews with the employees at Almedahl-Kinna can be considered as the foundation of the result of this thesis. Result of the thesis is a shared process-based management system for Almedahl-Kinna developed in a business process map.The result also consists of sub-processes linked to the core process of the BPM. The sub-process is based on the inputs and outputs found in the core process.A common vision between Almedahls and the study group was essential to achieve an acceptable result in the end, hence the project was driven by an initial BPM provided by Almedahls and in fact it became one of the main aims of this project: how to change the management’s point of view towards thinking in processes?Based on the nature of process-based management systems, the idea to choose this system was correctly selected for Almedahls to gather all four strategy business areas and three companies together.
