Abstract
This paper discusses the adoption level of and experiences from using agile 
practices in three software development projects in a large Telecom company. 
The use of agile practices was more emergent than planned. Project managers 
and developers simply used practices they considered efficient and natural. 
The most widely adopted agile practices were to measure progress by working 
code, to have developers estimate task efforts, to use coding standards, 
having no continuous overtime, to have the team develop its own processes, 
to use limited documentation, and to have the team in one physical location. 
The projects used conventional testing approaches. Adoption of agile testing 
practices, i.e., test first and automated unit tests, was low. Some agile 
practices can just emerge without conscious adoption, because developers 
find them useful. However, it seems that an emergent process aiming for 
agility may also neglect important agile practices.
