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.”

Prototyping Tools: Does Fidelity Really Matter? Ledoux and Hoffman (2006)

Consider Multiple Factors When Selecting Prototyping Tool

•Publishable to a website?

•Platform independent?

•Shared workgroup?

•Cost?

•Code output?

•Multiple fidelity renderings?

•Data integration?
