Product development, in-house or in collaboration with other parties, is considered one of the key issues to consider for any company interested in developing its business. Software of some kind is increasingly central to new products. At the same time standards and standardisation processes are affecting more and more aspects of society, increasingly so due to the globalisation of the world economy. This thesis takes an exploratory approach to what interactive roles the phenomena standards and standardisation take in product development processes involving software and viewed this from multiple organisational levels. By analysing two cases, the conclusion that standards have several different faces and standardisation has different phases is drawn. It is also concluded that standards and standardisation are complex and dynamic, but manageable. Regardless of the organisational level studied, standards and standardisation involve the management of people interacting. For future research it is suggested that standardisation processes are researched from the perspective of the arenas where they are shaped. Future research should also include a better understanding of when it is advisable for a company to take an active approach to standardisation.
