What is usability testing?

Data analysis

• List of problems / issues• Quantitative data (timings, counts,

…)• Qualitative data (comments, ...)• Comments observer• Etc.

How many test usersdo you need?

More rounds of small scale tests

1. 1st round: most significant problems2. Fix these problems…3. 2nd round: new problems uncovered4. Fix these problems…5. Etc.

How many times do you test during a project?

Many teams only conduct tests as an afterthought, the cost to change is enormous…

“When a test goes out we look at the data immediately and adapt the products quickly. We do this on a daily basis”https://www.facebook.com/notes/facebook-engineering/building-and-testing-at-facebook/10151004157328920/
