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•Representative of the end product
•Conceptual design > Prototype > Product
•Models: Throwaway, Evolutionary, or
Incremental
•Built for: Stakeholders, Designers, Users

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

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

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 “…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.”

Consider Multiple Factors When Selecting Prototyping Tool
•Publishable to a website?
•Platform independent?
•Shared workgroup?
•Cost?
•Code output?
•Multiple fidelity renderings?
•Data integration?
