Presentation Transcript

  1. Visual support for requirement elicitation technique Presented by, Nithin Shenoy Nimmy Joshy Guide Dr. A. Serebrenik (TU/e) Barbara Pareglio (Ericsson)

  2. Introduction • Requirement elicitation • Process of discovering the requirements for a system by communication with customers, system users and others who have a stake in the system development[1]. • Importance • First step towards identifying the “Right things to do” and “Doing the things right” • Challenges • Ambiguous requirements, • Assumed requirements • Conflicting requirements / SET Seminar

  3. Contd.. / SET Seminar

  4. Requirement elicitation with visualization Picture = 1000 words!!! Better understanding of requirements Can help identify new requirements Better way of keeping track of requirements / SET Seminar

  5. Objective Literature study of requirement elicitation techniques. Feasibility study of visual support for requirement elicitation techniques in Ericsson. / SET Seminar

  6. Requirement elicitation techniques • Categories [2] • Conversational • Interviews, focus group, workshop, brainstorming • Observational • Task Observation, protocol analysis • Analytic methods • Card sorting, Laddering • Collaborative • Scenarios/Use cases, prototyping / SET Seminar

  7. Contd.. Which elicitation technique to choose? • So many elicitation techniques / SET Seminar

  8. Framework to choose elicitation techniques • A framework is required to decide on elicitation techniques to be used based on the project [4]. • Decision making needs two types of information • Attributes • Recommendations on adequacy • The attributes describing the same context are grouped into factors. / SET Seminar

  9. Contd.. Factors Elicitor Informant Problem domain Elicitation process Different factors identified / SET Seminar

  10. Contd.. High … … … Low Zero / SET Seminar Elicitor attributes

  11. Contd.. • Recommendations on adequacy of techniques for certain values of attributes / SET Seminar

  12. Visualization support • Commonly used elicitation technique is interviews • Open ended • Closed • Identification of visualization tools • Visualization using mind mapping technique / SET Seminar

  13. Visualization Tools • Some of the tools identified • Free Mind • XMIND • VUE (Visual Understanding Environment) / SET Seminar

  14. Example – FreeMind / SET Seminar

  15. Future work Applicability of visualization tool for other requirement elicitation techniques Feasibility study of visual support for requirement elicitation techniques. / SET Seminar
