Part III—Deciding to Use Paper
The following three chapters delve into the nitty-gritty of what paper prototyping is and isn't good for,
whether it might make sense to use for your project, and the sorts of objections you might face from
your co-workers when you pitch the idea to them.
Chapter 12 , What Paper Is Good For: Paper prototyping is a useful technique, but it is not perfect.
This chapter outlines the kinds of usability problems that paper will (and won't) typically find.
Chapter 13 , The Politics of Paper: It's one thing to convince yourself that paper is worth trying, but
it's quite another to convince your co-workers. Common concerns about paper prototyping (validity,
bias, professionalism, and resources) are discussed.
Chapter 14 , When to Use Paper: Various circumstances of your project, staff, and development
environment can affect your decision of whether to test with a paper prototype. (Strictly speaking,
this chapter should precede Chapter 5 , which also pertains to planning. I've placed it here because
it may contain more detail than some people need.)
Part IV—Broadening the Focus
This section encourages you to think about how paper prototyping relates to the overall process of
product development.
Chapter 15 , Examples of User-Centered Design: Descriptions are provided of some real
companies that use paper prototyping as one of several techniques in their user-centered design
process.
Chapter 16 , Final Thoughts: This is a short but thought-provoking list of my own unanswered
questions about paper prototyping.
And last of all, there's a References section with all the topics and papers referenced throughout the
topic, plus plenty of suggestions for further reading.
