Lean User Testing Best Practices – UX Camp Hamburg 2015


Published on

The book “Lean User Testing” is a practical guide for everyone who wants to design, create or market software: Product managers, developers, designers (UX/UI), entrepreneurs, and marketing and sales people.

“Lean User Testing” is based on the author’s experience after interviewing hundreds of users. In just two or three hours, it will provide you with all the knowledge necessary to organize and run your first user tests. The results will be instantly beneficial: For 10% of the budget required for a professional usability agent, 80% of the findings can be recorded.

So, whoever wants to give software development a serious try…those who want to create a valuable service for their clients or their own company…those who would like to avoid bad investments in presumed killer features and/or products — if this describes you, you will find everything you need to know in this book.
