In simple terms…
Your account of the reasoning behind your design solutions The steps you went through The design decisions you made The basis for those decisions
Iterative exploration
From: Kenniskring HCI Hogeschool Rotterdam
Design never is a soletary effort
“Design is compromise.”
Bill Buxton in ‘Sketching User Experiences’
Sketching the experience
Sketches, visualizations or prototypes serve to suggest, propose and question design ideas. For you to explore To communicate to and share with others
Ideas need to be scrutinized, criticized and challenged to improve:
“criticizing your way to the solution” Scott Jenson (2002) in The Simplicity Shift
Documenting the design rationale
An explicit design rationale will: Stimulate a clear reasoning, shared and
understood by all (e.g., engineers, client) Prevent getting locked into your previous decisions
(e.g., with changing requirements)
A good design rationale
Is captured while the design process is progressing
Documents this design processContains visual representations of the design,
from the various phases of the design processContains the main design decisions throughout
the design process explicitlyContains the underpinnings of all design
decisions, preferably objectively and research based
Objective and research-based design decisions
“Knowing both what we want the site to accomplish for our organization and what we want the site to accomplish for our users helps inform all decisions we have to make about every aspect of the user experience.”
Jesse James Garrett (2002), The Elements of User Experience
Objective and research-based design decisions
Research can be research you conducted, or someone else has conducted
Objectivity is provided by documenting your own research (reproducibility) and/or traceable (trustworthy) sources
