(pdf) Review of a problematic segment of an on-device interface for a major medical device manufacturer.

Why it works

This presentation was to embedded software engineers, so they needed a small amount of stage-setting: what should we attempt to accomplish in improving the interface? WHat changes will help, and how?

What I’d change

I could have focused more on removing user decision-making from the processes implied by the existing interface. Likely this would have resulted in even greater intelligibility and significant interface reduction. Even so, the difficulty of the proposed changes caused the engineering staff to stretch meaningfully.
