In recent years, people have claimed that plan-based and agile companies use very different project management techniques. As this claim has a deep implication on how to run a software business, the authors set up an empirical study to assess analogies and differences caused by adopting agile methods from the point of view of project management.
Twenty managers of plan-based (traditional) and agile companies participated in the study by filling out a questionnaire. The authors' analysis of these questionnaires shows that managers using agile methods focus on people and process more than other managers. According to this study, adopting agile methods appears to offer a good solution for improving the management of the development process and customer relationships.
