Sammanfattning
Abstract
In today’s fast-paced world, there is a constant demand for better and more efficient ways of doing business.
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.

Abstract
In today’s fast-paced world, there is a constant demand for better and more efficient
ways of doing business. 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.
