LEVELS OF ABSTRACTION:
More than computer science buzzwords

Usability Issue:Users were not provided with enough information to form appropriate conceptual models of the automatic or manual processes
AUTOMATIC/MANUALORIGINAL DESIGN
![Page 14: Speed Up Solutions](https://reader035.vdocument.in/reader035/viewer/2022062521/56816935550346895de08fa1/html5/thumbnails/14.jpg)
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”

AUTOMATIC SUMMARYORIGINAL DESIGN
REDESIGN
Usability Issue:o Users believe they
can and want to decide whether they accept changes made by automatic process
o Users can undo and redo changes made

DISC CLEAN UPORIGINAL DESIGN
Usability Issue:o Confusion about fileso Intimidating and decision intensive (one user even
skipped!)

I should not touch these
I decide if I need them anymore

Concept Model for Disc Clean Up:
“I put them there”
“I thought it would be like defragmenting and get rid of unnecessary things”

Usability Issue:o Users could not tell
the initial or changed status of each process

o Current and possible states for each process are visible

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?

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.
