GOALS

DEMO

Usability Issue:Users were not provided with enough information to form appropriate conceptual models of the automatic or manual processes

AUTOMATIC/MANUALORIGINAL DESIGN

AUTOMATIC/MANUALCRITIQUE

Lack of information lead users to form faulty conceptual models

Automatic= “a guide through like my tax software”

Manual= “probably too complicated for me”

“I thought it would be like defragmenting and get rid of unnecessary things”

DISC CLEAN UPCRITIQUE

DISC CLEAN UPREDESIGN

STARTUP CLEAN UP

Usability Issue:o Users could not tell

the initial or changed status of each process

ORIGINAL DESIGN

REDESIGN

o Current and possible states for each process are visible

Usability Issue:Learn More content was either never accessed or left users still feeling confused

LEARN MOREORIGINAL DESIGN

What do users anticipate Learn More is?

That’ll just be a big block of text I don’t understand.

Why should I make a process

not run on startup?

What are users thinking when we expect them the use Learn

More?

How do I know if I need to perform

disc clean up?

Revisiting Concept Models:

LEARN MORECRITIQUE

o Users don’t have to search through a big block of text to the answer to their specific question.

o Users can keep answers to questions up while they work on speed up step.

o Acknowledges that users may be asking questions while considering screen.
