2 : an underlying reason

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

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’

“ 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

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 )

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 process Contains visual representations of the design, from the various phases of the design process Contains the main design decisions throughout the design process explicitly Contains the underpinnings of all design decisions, preferably objectively and research based

Is captured while the design process is progressing

Documents this design process

Contains visual representations of the design, from the various phases of the design process

Contains the main design decisions throughout the design process explicitly

Contains 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

“ 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.”

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
