Introduction
This section outlines the goals of the book, what the reader should walk away with, and provide an overview to what prototyping is, how to use prototypes as a design, research, and communication tool, how they can work prototyping into their design and development process, and when to, as well as when not to prototype. Examples of prototypes will be provided here.

Chapters

• What is a prototype?
• What is the value of prototyping?
  • Practitioner value
  • Business value
• When and when not to prototype
• Where does it fit in the design process?

Planning Your Prototype
This section lays the foundation for the “How to” part of the book.

Chapters

• Knowing what to prototype
• Setting expectations
• The question of fidelity
• Understanding the audience, goals, and intent
• Prioritize - build only what you need

Methods and Tools
The goal of this section is to help the reader make an educated decision in choosing the appropriate prototyping method. This section would provide the reader an in-depth understanding of:

• Overview of lo-fi and hi-fi methods
• Tools
• Methods for prototyping interactions for the web, mobile devices, and RIAs

The reader will learn the strengths and challenges of each method, when to use lo-fi (paper) vs. hi-fi interactive, the amount and type of resources needed for each, as well as what to expect from each method. The book will use stories from the field (case studies) to walk the reader through the decision making process. The stories will discuss which prototyping method was chosen, why, and the cost/benefit to the project.

Chapters

• Lo-fi methods and tools
  • Paper
• Hi-fi methods and tools
  • HTML/CSS
  • Flash/Flex
  • PPT
• Prototyping interactions for the web
• Prototyping and RIAs
• Prototyping and mobile devices

Testing
This would provides readers with an overview of what’s involved in testing a prototype, including some best practices. Readers will be referred to other resources for more in-depth information on usability testing. Additionally, this section will discuss how to use prototypes to collect specific data to improve your design. Screen casts and example files would be available for download.

Chapters

• Planning and script development
• Testing do’s and don’ts
• Recording and analysis

Next Steps
The goal of this section is to help readers understand how prototypes improve products through data-driven design decisions. This section will also speak to prototyping’s ability to streamline development.

Chapters

• Prioritizing design decisions
• Refining your design
