A Practical Guide to Measuring Usability: 72 Answers to the Most Common Questions about Quantifying the Usability of Websites and Software

Packed full of great material. It is a good reference to quickly review methods to spark ideas.

As a practitioner in the usability field, I have come to depend on this guide for my usability testing. It tackles some long held best practices (i.e. - Do I only need to test with 5 users?) and arms you with the information necessary to make an educated decision about whether 5 users is enough based on what your trying to accomplish with the test.It succinctly answers probably EVERY question I've ever had about performing quantitative usability tests, and answers some I didn't know I should be considering. I can quickly find the answer I'm looking for (because it's organized by "questions") and not lose valuable time during a project.After having this booklet a while, I became (in full disclosure) big fan of the authors website devoted to "measuring usability" and look forward to his weekly blogs. ([...])I can't emphasize enough how crucial this guide has been for me and the teams I've worked with. I bought several copies and gave them out to others on our Usability Testing team so we could use it as our "Playbook".

Like other Sauro books, it's extremely well written and concentrates on real world practice and questions. I would almost call this the usability practitioners field guide because it could almost fit in your pocket and join you on testing site.

Saura's knowledge of usability is well reflected in this book. I'd highly recommend this book to anyone researching usability.
