  1. Requirements Engineeringin Global Software Development:Challenges and Opportunities by Ian Bui SYSM 6309 UTD - Spring 2012

  2. Abstract • Motivation • Globalization of Software Industry creates unprecedented challenges for GSD • Problem • Requirements Engineering lacks a working model to deal with the emerging issues of GSD • Solution • Tools, Research, Education • Examples • Two Case Studies

  3. GSD Context • Multiple teams spread across the globe • Customers and Users geographically diverse • Communication Issues

  4. Case Study I • A Global Software Development Organization • Functional Teams spread out geographically • Research conducted from beginning to end of project • Multiple stakeholders interviewed • Survey questionnaires

  5. Major Issues • Inadequate Communication • Knowledge Management • Cultural Diversity • Time Difference

  6. Main Challenges • Geography • Trust • Politics • Communication

  7. ExampleSapphire Software (NZ)

  8. Case Study II • Focuses on Stakeholders Management • Offers a new model of Stakeholders in GSD • Lists important processes for RE in GSD • Suggests some coping strategies • Recommends tools

  9. New Model of Stakeholders in GSD

  10. Major Processes for RE in GSD • Knowledge Acquisition and Sharing • Too many layers reduce ability to exchange information • Aligning RE Processes and Tools across sites • Not all organizations use the same processes or use them the same way • Effective Communication and Coordination • Informal conversations are important to understand context and gather tacit knowledge

  11. Coping Strategies • Supporting Interorganizational Structures • Define stakeholder rolesand responsibilities • Establish peer-to-peer lines of communication • Synchronize processes and have frequent reviews • Establish cultural liaisons • Supporting Communication Practices • Maintain open communication among stakeholders • Frequent updates and reports on progress

  12. Tool Recommendation • EGRET: distributed Change Mgmt, Knowledge Mgmt, Informal Collaboration • IBIS: Internet-based Inspection System, supports Requirements Negotiation • Bjorn Regnell: Method for visualizing Market Requirements and Prioritization • DCPT: Distributed Collaboration and Prioritization Tool, uses WinWin Requirements Negotiation system • RequisitePro: commercial RE product from Rational • DOORS: commercial RE product from Telelogic

  13. Conclusions • GSD is pushing RE to evolve to the next level • Opportunities exist for: • Tools Developers • Standards Bodies (e.g. IEEE) • Education • “RE in GSD” multi-site class held at University of Victoria (Canada), University of Technology (Sydney), University of Bari (Italy) • Students participated as both clients and developers in different projects across multiple locations and time zones
