2 Agile Methods for Distributed Software Development: Communication is Crucial Agile software development: Goal: get fast results Reducing overhead of classical software development Can agile methods be applied in distributed software development (DSD)? Every third DSD project teams < 10 members Direct communication between team members important Plays crucial role in application of agile methods Need to compensate for the inability to meet face-to-face! Tool-oriented approach 2 06 February 2009 Agile Knowledge Sharing for Distributed Software Teams (AKNOWLEDGE 08)

3 State-of-the-art Tools for DSD State of the art: traditional tools for on-site development Based on client server paradigm Centralized architecture orthogonal to the natural structure of DSD! Communication + data exchange over server Server must always be available Communication bottleneck Poor scalability Additional latency Suboptimal resource consumption Single point of failure High set-up and maintenance costs 3 06 February 2009 Agile Knowledge Sharing for Distributed Software Teams (AKNOWLEDGE 08)

4 Benefits the Peer-to-Peer Paradigm Each communication participant offers and consumes services Communication + data exchange done directly Significantly lower costs Self organization Optimal resource usage No maintenance costs Decreased delay Robust 4 06 February 2009 Agile Knowledge Sharing for Distributed Software Teams (AKNOWLEDGE 08)

5 A Peer-to-Peer based Support Tool for Agile Development: ASKME ASKME: Awareness Support Keeping Messages Environment P2P instant messager as Eclipse plugin: Offline messaging Highlighting developer who modified the opened code most recently 5 06 February 2009 Agile Knowledge Sharing for Distributed Software Teams (AKNOWLEDGE 08)

6 Offline Messaging: Nowadays 6 06 February 2009 Agile Knowledge Sharing for Distributed Software Teams (AKNOWLEDGE 08)

7 Offline Messaging: Nowadays Sender is on vacation After 1 month the Receiver message doesn t is have delivered. any clue that someone tried to contact him 7 06 February 2009 Agile Knowledge Sharing for Distributed Software Teams (AKNOWLEDGE 08)
