A Vertical Approach to Knowledge Management: Codification and Personalization in Software Processes

Software process improvement is a practical concern in software companies today and it has been addressed in research. Part of this research has applied a knowledge management perspective. Researchers point out that two different strategies exist where a mixture is difficult to maintain: Personalization focus on people and their collaboration and codification focus on documents and their accessibility. This paper addresses different knowledge management problems of a software company and how they can be alleviated. A prototype, which distinguishes between different organizational levels e.g., software managers and software developers and applies different knowledge management strategies, was built. It consists of a wiki and an enterprise system. This article shows how each part of the system focuses on one of the strategies and describes the differences for tool support. This combination could be beneficial because the connection between the two different parts of the prototype works. Further implications for practitioners are explained.

Recommending Open Linked Data in Creativity Sessions using Web Portals with Collaborative Real Time Environment

In this paper we describe a concept of the recommender system for col- laborative real time web based editing in the context of creativity sessions. The col- laborative real time editing provides creativity teams of which members are physically distributed with an emulation of the synchronous collaboration where presence of the team members is required simultaneously (e.g., brainstorming, meetings). The concept of recommendation is based on matchmaking the currently performed activities at the user interface and external linked open data provided through SPARQL endpoints. The real time propagation of the changes in editor and recommendation is achieved by reverse AJAX and observer pattern. An experiment in the area of the creativity domain shows that the recommendation in collaborative real time editing activities are useful in task performance, guidance, and inspiration.
