Download or read book High Performance Web Sites written by Steve Souders and published by "O'Reilly Media, Inc.". This book was released on 2007-09-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. 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 Requests Use a Content Delivery Network Add an Expires Header Gzip Components Put Stylesheets at the Top Put Scripts at the Bottom Avoid CSS Expressions Make JavaScript and CSS External Reduce DNS Lookups Minify JavaScript Avoid Redirects Remove Duplicates Scripts Configure ETags Make Ajax Cacheable If 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 Inspector "Steve 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

Download or read book Unlocking High Performance written by Jason Lauritsen and published by Kogan Page Publishers. This book was released on 2018-10-03 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional performance management processes are often ineffective in increasing workforce engagement and fostering a positive employer-employee relationship. The established method of annually scoring employees against a list of static objectives can make employees feel undervalued and frustrated and can hinder, rather than advance, staff development. Unlocking High Performance shows you how to transform this process to get the best out of your workforce. It presents a new model for performance management based on the three components of planning, cultivation and accountability, and situates this process within the wider aims of promoting work as a healthy relationship between employer and employee rather than a restrictive contract to be complied with. Unlocking High Performance equips you with the tools needed to create clear expectations and goals, deliver feedback effectively, and to develop a culture of coaching rather than criticism. This book also provides practical guidance on how to identify and remove obstacles, effectively manage underperformance, and how to get buy-in for change. Packed with tips, tools and examples from organizations including Vistaprint, NVIDIA and South Dakota State University, this book provides everything needed to design a performance management process which will improve employee experience, help them reach their full potential, and ultimately deliver exceptional business results.

Download or read book Deep Purpose written by Ranjay Gulati and published by HarperCollins. This book was released on 2022-02-08 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thinkers50 Top 10 Best New Management Books for 2022 A distinguished Harvard Business School professor offers a compelling reassessment and defense of purpose as a management ethos, documenting the vast performance gains and social benefits that become possible when firms manage to get purpose right. Few business topics have aroused more skepticism in recent years than the notion of corporate purpose, and for good reason. Too many companies deploy purpose, or a reason for being, as a promotional vehicle to make themselves feel virtuous and to look good to the outside world. Some have only foggy ideas about what purpose is and conflate it with strategy and other concepts like “mission,” “vision,” and “values.” Even well-intentioned leaders don’t understand purpose’s full potential and engage half-heartedly and superficially with it. Outsiders spot this and become cynical about companies and the broader capitalist endeavor. Having conducted extensive field research, Ranjay Gulati reveals the fatal mistakes leaders unwittingly make when attempting to implement a reason for being. Moreover, he shows how companies can embed purpose much more deeply than they currently do, delivering impressive performance benefits that reward customers, suppliers, employees, shareholders, and communities alike. To get purpose right, leaders must fundamentally change not only how they execute it but also how they conceive of and relate to it. They must practice what Gulati calls deep purpose, furthering each organization’s reason for being more intensely, thoughtfully, and comprehensively than ever before. In this authoritative, accessible, and inspiring guide, Gulati takes readers inside some of the world’s most purposeful companies to understand the secrets to their successes. He explores how leaders can pursue purpose more deeply by navigating the inevitable tradeoffs more deliberately and effectively to balance between short- and long-term value; building purpose more systematically into every key organizational function to mobilize stakeholders and enhance performance; updating organizations to foster more autonomy and collaboration, which in turn allow individual employees to work more purposefully; using powerful storytelling to communicate a reason for being, arousing emotions and building a community of inspired and committed stakeholders; and building cultures that don’t merely support purpose, but also allow employees to link the corporate purpose to their own personal reasons for being. As Gulati argues, a deeper engagement with purpose holds the key not merely to the well-being of individual companies but also to humanity’s future. With capitalism under siege and relatively low levels of trust in business, purpose can serve as a radically new operating system for the enterprise, enhancing performance while also delivering meaningful benefits to society. It’s the kind of inspired thinking that businesses—and the rest of us—urgently need.
