    The Persona Lifecycle addresses the how of creating effective personas and using those personas to design products that people love. It doesn't just describe the value of personas; it offers detailed techniques and tools related to planning, creating, communicating, and using personas to create great product designs. Moreover, it provides rich examples, samples, and illustrations to imitate and model. Perhaps most importantly, it positions personas not as a panacea, but as a method used to complement other user-centered design (UCD) techniques including scenario-based design, cognitive walkthroughs and user testing. The authors developed the Persona Lifecycle model to communicate the value and practical application of personas to product design and development professionals.This book explores the complete lifecycle of personas, to guide the designer at each stage of product development. It includes a running case study with rich examples and samples that demonstrate how personas can be used in building a product end-to-end. It also presents recommended best practices in techniques, tools, and innovative methods and contains hundreds of relevant stories, commentary, opinions, and case studies from user experience professionals across a variety of domains and industries.This book will be a valuable resource for UCD professionals, including usability practitioners, interaction designers, technical writers, and program managers; programmers/developers who act as the interaction designers for software; and those professionals who work with developers and designers.

    The goal of the book is to share the techniques of the best companies. This book is aimed primarily at Product Managers working on technology-powered products. That includes the hundreds of "tech companies" like Google, Facebook, Amazon, Twitter and the like, as well as the thousands of companies moving to leverage technology (financial companies, media companies, retailers, manufacturers, nearly every industry). Inspired covers companies from early stage start-ups to large, established companies. The products might be consumer products or devices, business services for small businesses to enterprises, internal tools, and developer platforms.Inspired is secondarily aimed at the designers, engineers, user researchers and data scientists that work closely with the product managers on product teams at these same companies.

    The shaping of digital artifacts is a design process that influences the form and functions of workplaces, schools, communication, and culture; the successful interaction designer must use both ethical and aesthetic judgment to create designs that are appropriate to a given environment. This book is not a how-to manual, but a collection of tools for thought about interaction design.Working with information technology--called by the authors the material without qualities--interaction designers create not a static object but a dynamic pattern of interactivity. The design vision is closely linked to context and not simply focused on the technology. The authors' action-oriented and context-dependent design theory, drawing on design theorist Donald Sch�n's concept of the reflective practitioner, helps designers deal with complex design challenges created by new technology and new knowledge. Their approach, based on a foundation of thoughtfulness that acknowledges the designer's responsibility not only for the functional qualities of the design product but for the ethical and aesthetic qualities as well, fills the need for a theory of interaction design that can increase and nurture design knowledge. From this perspective they address the fundamental question of what kind of knowledge an aspiring designer needs, discussing the process of design, the designer, design methods and techniques, the design product and its qualities, and conditions for interaction design.

    Designing anything for people is tough, because we’re inherently complex and...well...messy. Which means that things like market share and ROI don’t come easy. But time and effort spent finding the right problems to solve allows designers, developers and product teams to take quantum leaps forward in exceeding the expectations of everyone involved. In Think First, Joe Natoli shows you exactly how to do this, using lessons learned from his 26 years as a UX consultant to Fortune 100 and 500 organizations. You’ll find proven principles, step-by-step methods and straightforward, jargon-free advice that can be applied to any kind of digital product. Think First proves that while people are indeed messy and complex, designing for them doesn’t have to be. Here’s what a few well-respected UX practitioners and authors had to say about Think First: “A very practical guide to success in business.” – Dr. Don Norman, Director of the DesignLab, UC San Diego and Author of The Design of Everyday Things “Think First is a practical guide to UX that makes sense of strategy and structure. Highly recommended!” – Peter Morville, Bestselling Author of Intertwingled “For designers and developers, understanding strategy and UX is an increasingly necessary skill. Joe Natoli’s Think First demystifies these foundational ideas in a very conversational, easy to read style.” – Ilise Benun, Founder of Marketing-Mentor.com and Author of 7+ Books Author Joe Natoli explains why he believes Think First is unlike any other book on the subject of UX strategy and design: "I didn’t want to write yet another book that covers the narrow, tactical pieces of the design process," he says, "because great design and great UX are the result of multiple activities across multiple people, roles and disciplines. It’s everybody’s business. Think First walks you through everything that must be considered to create great UX — and gives you a roadmap to make it happen." Think First details Joe's no-nonsense approach to creating successful products, powerful user experiences and very happy customers. He share countless lessons learned from more than 26 years as a UX consultant to Fortune 500 and 100 organizations — including a few he's learned the hard way :-) Think First serves as a roadmap to building a solid foundation for UX that’s strong enough to withstand any weather as projects move into design and coding. Here are just some of the things you’ll learn: - Simple user research methods that anyone can perform — even if you’ve never done research of any kind. - The right questions to ask stakeholders and users at the outset of any (and every) project. - The 3 crucial questions you must ask of every client, every time. - How to tell the difference between what people say they need vs. what they really need. - A better, simpler way to generate meaningful UX requirements at the outset of the project. - How to figure out what features and functions will result in great UX and deliver value to both users and the business. - How to avoid scope creep and the never-ending project scenario.

    Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to: Make Fewer HTTP RequestsUse a Content Delivery NetworkAdd an Expires HeaderGzip ComponentsPut Stylesheets at the TopPut Scripts at the BottomAvoid CSS ExpressionsMake JavaScript and CSS ExternalReduce DNS LookupsMinify JavaScriptAvoid RedirectsRemove Duplicates ScriptsConfigure ETagsMake Ajax CacheableIf you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable.If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore.-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM InspectorSteve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance.-Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation
