Abstract [en]

GKN Aerospace Sweden AB in Trollhättan (abbreviated to GAS) develops and produces high quality parts for several aircraft OEM’s (including e.g. Rolls Royce and Pratt and Whitney), majorly comprising engines. Safety jurisdictions and level of technology have increased greatly over the past years in the aerospace industry, which has led to increased amount and level of demands and requirements, affecting the whole supply chain for every specific product in affected industries. New degree of demands are more difficult to assure while it at the same time increases the amount of data, information and knowledge along the life cycle of a product. An investigation was therefore established for evaluating: (1) How is the usage of measurement data (MD) effected depending on where in the product life cycle it is used? (2) What are the major obstacles against reuse of measurement data in technology, product and production development? (3) What technology and system has to be in place in order to support reuse of measurement data in technology, product and production de-velopment?The investigation was undertaken with a project strategy of PDSA (Plan-Do-Study-Act) structure and the study was conducted inside of the firms’ industrial walls in order to establish a close-up thorough investiga-tion. With tools e.g. interviews, surveys, affinity diagrams, statistical tools and wide academic bases, empirical data of both qualitative and quantitative kind could be gathered. The interviews and observations established the major basis for the investigation with support from the survey about e.g. information and communication flows, departmental relations, specific needs, worker duties and vast issues or limitations. The findings was analyzed with support from a life cycle model for experience (i.e. data, information and knowledge) and con-clusions could be made for assuring that experience could be reused. Also, in the analysis particular attention was given towards communication since such affects the reuse process of new product development projects as well.It was found that (1) the studied company is generally good at perceiving the usage and implementation of MD in its processes over the whole product lifecycle, i.e. knowledge about usage of MD is present at GAS to a high degree. However the present company structure does not allow for an effective usage of MD in early stages of the product life cycle, suggesting problems with insufficient; IT-environment, repositories of MD, communication platforms, information media, and measurement standards, affecting the Pull process nega-tively (comprising activities of Search, Access and Use of MD). (2) The mindset towards using MD is con-sidered reactive since measurements mostly are conducted towards verification of product quality in produc-tion. Added to this, manual labor-based way-of-working and systems with unsupportive structure towards reuse of experiences with enough usability, traceability and availability was also found to be true. (3) The firm was concluded to be in need of a heterogeneous IT-based system allowing the transition of saving correct digital experience and receiving such with enough value and context for the specific user. The study is concluded with recommendations to GKN Aerospace Sweden AB along three different spans of 0-5, 5-10 and 10-20 years of time, where the major part is to be seen as a vision or long term strategy to strive for. The first span consists of boosting locally evolved but not fully implemented initiatives in the com-pany, allowing for the first important basis to be set. The 5-10 year span was comprised with implementation of a new heterogeneous IT-based system, acting as stable foundation for the next industrial revolution to be seen as the conceptual strategy to strive for later on along the 10-20 year recommendation. The whole rec-ommendation and this thesis is believed to allow the firm to be proactive in future product developments since information is proposed to be the new success driver towards business success and competitiveness.
