  6. 6. Agenda • Introduction • About prototyping • Prototyping tools • Case Study and demo 6
  7. 7. Prototypes: A Definition Artifacts or experiences designed for exploring alternatives and options of interactive systems. Intended reduce the risk of committing time and resources to full production without validation of direction. • Representative of the end product • Conceptual design > Prototype > Product • Models: Throwaway, Evolutionary, or Incremental • Built for: Stakeholders, Designers, Users 7
  8. 8. Benefit 1: Stakeholders Envision Solution Early in Design Process “In the last year, 70% of projects failed to meet deadlines, & 50% of projects failed to meet the needs of the business; 80% of the issues stem from poor requirements.” - Standish Group Chaos Report, 2007 8
  9. 9. Benefit 1: Stakeholders Envision Solution Early in Design Process 1. Stakeholders don’t know what they want until they see something and interact with it 2. Experience is difficult to envision by looking at specification documents and use cases Leads to: • Re-work and changes • Project delays • Compromises and time pressures • Poor relationships 9
  10. 10. Benefit 2: User Feedback Early in the Design Process Internally- Internally-Centered Process: Requirements Request Create Review Updates Launch Document User-Centered Process: User- Gather Low- Low-fidelity Usability Create Usability Review Request user needs prototype Test Test User Input User Input User Input Reviews Updates Launch 10
  11. 11. Benefit 2: User Feedback Early in the Design Process “When presented with a single design, users give significantly higher ratings and were more reluctant to criticize than when presented with the same design in a group of three.“ “…results imply that by presenting users with alternative design solutions, subjective ratings are less prone to inflation and give rise to more and stronger criticisms when appropriate.” Tohidi, M., Buxton, W., Baecker, R. & Sellen, A. (2006). 11
  12. 12. Traditional References to Prototypes Potentially Off Target Prototyping Tool • Visio • Axure • Paper Fidelity • High • Medium • Low 12
  13. 13. Alternate Models Suggest Different Way to Think About Prototypes What do Prototypes Prototype? Houde and Hill (1997) 13
  14. 14. Fine Line Between Sketching and Prototyping 14
  15. 15. Agenda • Introduction • About prototyping • Prototyping tools • Case Study and demo 15

  17. 17. Varying Feature Sets and Costs Prototyping Tools: Does Fidelity Really Matter? Ledoux and Hoffman (2006) 17
  18. 18. Consider Multiple Factors When Selecting Prototyping Tool • Publishable to a website? • Platform independent? • Shared workgroup? • Cost? • Code output? • Multiple fidelity renderings? • Data integration? 18
