Motorola in Linköping are using the agile development framework, Scrum in their software development. A certain level of quality must also be assured of the delivered goods and services. Is it possible to use Scrum and still meet the quality requirements? This Master Thesis is performed to investigate if it is possible to achieve a quality certificate from TL 9000, the telecom industry extension of ISO 9000, when using the agile development framework Scrum. The investigation consists of interviews and observations at Motorola, Linköping, along with literature studies about quality systems and agile development. The conclusion is that it is possible to meet the TL 9000 requirements when using Scrum, under the condition that some additional processes are performed and that other parts of the organization also fulfills the remaining requirements. This is needed since there are requirements that are out of scope for the Scrum framework. Examples of the suggested additions are to follow the Scrum framework more strictly and to adopt a more specific definition of done.

Acknowledgements After five intense months of reading, discussing, and writing, this Master Thesis concludes our Master of Science at Linköping University. Without the help and support from a number of people, we doubt that this thesis would have been written. First, we would like to thank our supervisors, examiner, and opponent. Håkan Markör and Mattias Hedlund at Motorola kindly offered us this interesting opportunity and continued to inspire, facilitate, and question our work. Vivian Vimarlund, Ph.D., at Linköping University contributed with invaluable feedback, suggestions, and advice throughout the project. Andreas “Goken” Anderljung read the report several times, and helped us by pointing out and suggest improvements for the weak parts. Thank you! We would also like to thank everyone else that has helped us in any way. Specifically we would like to mention a few people. Our friends and colleagues studying Master of Science in Information Technology at Linköping University helped us understand how a team works, why a whiteboard is a necessary tool and that “fika” is a great thing. The time we spent together was not just fun, we actually gained invaluable experience. Susanne Ejdfors Eriksson welcomed us to share her room the first weeks and introduced us to the company. Niklas Storm generously shared his expertise concerning quality management and TL 9000 by helping us interpret the Requirements Handbook. Henrik Gidmark offered us rewarding discussions about group dynamics, leadership, and organizational issues sharing his experience from the corporate world. John Edeus always had time for a chat and a joke, and open heartedly shared his wisdom and real life experience. Mikael Adlers gave us a better understanding of what Scrum is and how it is used at Motorola. Ivy Pascoe and Jos Koster invited us to attend a TL 9000-audit that clarified the connection between theory and practice to us. Carl Ljungström kept us company, especially when we were busy, and helped us balance between working harder and relaxing. The interviewees, you know who you are, gave us unique insights into the organization that would have been impossible to gain otherwise. Everyone at Motorola Linköping helped us with a warm and welcoming attitude. Finally, we would like to thank our families and friends. You encouraged and supported us. We owe you everything! Based on the feedback and insights offered by reviewers, we have attempted to address the issues raised. However, any errors, oversights, or omissions remaining are our sole responsibility.
