Currently, agile methods are replacing traditional process-based methods in the software industry. However, process-based software development still matters because of its degree of reusability in new projects. Some problems arise when Knowledge Management (KM) is not correctly aligned with processes, such as lack of productivity and process improvement. In this chapter, the authors present a case study of applying two proposals of process libraries in an agile software development division. The researchers and the software development division worked with a Kanban dashboard, eXtremme Programming (XP), and SCRUM practices, adapted to Process Assets Library (PAL) and to Process Practice Library (PPL) in three software projects in order to find experiences of tacit and explicit knowledge that have an impact on process improvement and productivity. Under results and discussion, the authors present the good and bad practices.
