    • ResearchProblems and Aim
      • Collaborative Requirements Elicitation
      • Challenges of Requirements Elicitation Workshops
      a) Diversity among stakeholders
      b)Software Requirements and User Requirements: Obstacles of elicitation and discovery
      c) Facilitation of workshops
      • Research Aim:
      Defining a collaborative pattern that supports facilitation of user requirements elicitation workshops and helps collaborating stakeholders to agree upon user requirements.
    • Methodology
      • Our approach: Collaboration Engineering (CE)
      “an approach to the design of re-usable collaboration processes and technologies
      meant to engender predictable and transferable processes, successfully conducted
      by practitioners of recurring mission-critical collaborative tasks.” (Briggs et al, 2003)
      - designing collaborative processes
      • Can be applied to same or similar recurring tasks or business problems in organizations (no need to re-design)
      • Transferrable to non-expert facilitators who have potentials to deliver the facilitation service
      • Application of CE Design Approach to Requirements Engineering
      • Briggs R.O de Vreede G. J. Nunamaker. J. F. (2003) Collaboration engineering with thinkLets to pursue sustained success with group support systems. Journal of MIS Quarterly 19(4) 31-63.
    • Applying CE to User Requirements Elicitation
      The Design Approach (Kolfschoten G. L.  de Vreede G. J. , 2007)
      Task Diagnosis: stakeholders’Consensus building in user requirements elicitation workshops
      Task Decomposition
      • Identify relevant user requirements.
      • Analyse features for each group of users and categorize user requirements into categories of user groups.
      • Analyse and Identify user requirements categories.
      • Discuss, define and agree user requirements in terms of features in each category.
      • Prioritize the final user requirements categories.
      • Agree on the overall categorized and prioritized user requirements.

    • Applying CE to User Requirements ElicitaionCont.
      ThinkLetChoice
      ThinkLets are facilitation building blocks. They contain scripts for facilitation and define patterns for collaboration. i.e. generating patterns like brainstorming thinkLets or categorizing patterns like categorizing thinkLets
      4. Agenda Design Validation
      5. Design Documentation
    • Figure-1: The Collaboration Pattern
    • Further discussion about the Designed Collaborative Process
      Application of the pattern to user requirements elicitation workshops
      • Workshop stages: Scope Workshops, High level Workshops and Detailed Workshops (E. Gottesdiener, 2002).
      • Exclusively designed for the scope workshops.
      A Pattern Language for User Requirements Elicitation:
      • Fact:
      1)ThinkLetsare design pattern used in Collaboration Engineering (CE) (de Vreede et. al, 2009)
      2) collection of design patterns form a pattern language ((de Vreede et. al, 2009)
       The designed collaborative process is a pattern language and contains the characteristics of a pattern language
