The purpose of this study is to provide recommendations to further develop and improvements of models which can be applied to IT governance models for system maintenance. The work investigates gaps in the implementation and using phase of the model pm3 and also models which are inspired in pm3. The aim of the present paper is to answer the research questions which are related to (1) which critical success factors that have an impact on the governance of system maintenance management and also for the model pm3 and (2) how maintenance management models can further be developed and improved. This qualitative study is a case study in which a questionnaire and interview in two steps have been completed. The sample of respondents have been made with a specific purpose that reflects the selected qualities and relevance of the study and also with a geographical distribution. The study resulted in a number of critical success factors for the model pm3 where some of these can be considered as general for all maintenance management models. The results shows the need of a maintenance management model that is designed for the agile working method and suitable for all types and sizes of organisations. It is an area where maintenance management models and pm3  need to develop within. / Syftet med denna studie är att kunna ge rekommendationer till utveckling och förbättringar av modeller som kan tillämpas vid IT-styrning av modeller för systemförvaltning. Arbetet undersöker brister i införandet och användandet av modellen pm3 samt modeller som är inspirerade av pm3. Studiens mål är att besvara frågeställningarna som behandlar (1) vilka kritiska framgångsfaktorer som har en påverkan för styrning av systemförvaltning samt för modellen pm3 och (2) hur förvaltningsstyrningsmodeller och pm3 kan utvecklas och förbättras. Den kvalitativa studien är en fallstudie där en enkätundersökning och två olika intervjusteg har utförts. Urvalet av respondenter har gjorts med ett specifikt syfte som speglar de utvaldas kvaliteter och relevans för studien samt med en geografisk spridning. Studien resulterade i en mängd kritiska framgångsfaktorer för modellen pm3 där en del av dessa kan anses som generella för alla förvaltningsstyrningsmodeller. Resultatet påvisar även behovet av en förvaltningsstyrningsmodell som är anpassad för det agila arbetssättet samt behovet av en modell anpassad för olika storlekar av organisationer. Vilket är ett område som förvaltningsstyrningsmodeller och pm3 bör utvecklas inom.

Maintenance has evolved over centuries and has played significant role for growth of organizations. Maintenance history is differentiated by three generations, the development of maintenance considered from being “necessary evil” to “profit contributor”. Many literatures have discussed maintenance for optimization and increasing profitability but little on the factors which influence on the future of maintenance. Maintenance should be considered as a “competitive factor” in the future. Many trends have evolved in production and every trend had a major contribution towards production development. The successful implementation of the trends is considered to be a major challenge. Little literatures have talked on the emerging trends and challenges in production. The thesis reviews the historical development of maintenance over generations and presents the key factors which play a major role during the fourth generation, and also identifies the emerging trends and challenges to be faced by production. The literature review, interviews and surveys were used in this thesis. Academic researchers and industrial experts from both maintenance and production department answered the interview and survey questions for this research. The key factors for the proposal of fourth generation of maintenance and the emerging trends and challenges to be faced by production are presented. The result from the research questions and the empirical findings are summarized in a framework that will enable readers to know the historical development of maintenance, the key factors to be considered for the fourth generation of maintenance and the emerging trends and challenges to be faced by production in future. In addition, the thesis also discusses the impact of information technology on the future of maintenance and the effect of sustainability in the future of production.

This thesis explores the consequences of neglect and lack of proper support and implementation in maintenance management models, specifically an old implementation of the Pm3 model. The area of study is not widely explored, with studies and evaluation of the specific model we have looked at being almost non-existent. We have conducted a qualitative case study at an IT department/company at a Swedish university and the data has been collected through interviews with different IT department leaders, as well as one interview with a representative with the company that owns and distributes the Pm3 model. The current software development methodology at the IT company studied in this thesis are agile methods but is locked down to a micro level, while the Pm3 model handles the macro level. The consequences of this are then compared against research within fields such as IT governance and IT/business alignment to find discrepancies from which the phenomena’s can be explained. With this thesis we want to explore the consequences of not maintaining maintenance management models in organizations, especially the Pm3 model as this is widely in Swedish institutions such as universities and government authorities. This thesis provides a word of caution and argue for the importance of maintenance in maintenance management models for such organizations.
