A New View on User Experience

A NEW VIEW ON USER EXPERIENCE "Speed is more than a feature; speed is the most important feature. If your application is slow, people won't use it. - Fred Wilson, Principal of Union Square Ventures Speed is crucial to forming exceptional user experiences, but so many companies struggle to optimize all the different components of their increasingly complex websites. HOW IS USER EXPERIENCE MEASURED? Typically, DevOps teams measure user experiences through "technical performance" metrics, which evaluate load times of the Web page and its parts. TECHNICAL PERFORMANCE METRICS INCLUDE: 1. THE WATERFALL REPORT - The traditional view of Web performance, which measures how long it takes the network to deliver every resource referenced in the website HTML to the browser. 2. DOM AND PAGE LOAD EVENTS- An evaluation of what the browser thinks about how fast the page is loading. *DOM = Document Object Model TECHNICAL PERFORMANCE METRICS have been the core of Web performance optimization - UNTIL NOW. 40% of DevOps professionals name "LACK OF VISIBILITY INTO IN-SCREEN TRANSACTIONS" as a major concern in their monitoring (according to a 2012 study from TRAC Research). TO ADDRESS THIS CRUCIAL NEED, A THIRD TYPE OF USER EXPERIENCE METRIC HAS RECENTLY EMERGED. IT EVALUATES THE VISUAL USER EXPERIENCE, MEASURING WHAT THE USER ACTUALLY SEES AT DIFFERENT POINTS IN THE LOAD PROCESS. IN A WAY, IT'S LIKE A SET OF ROBOT EYEBALLS According to a 2012 study from TRAC Research, 61% of IT staff who are in charge of managing application performance in the pre-production stage want more visibility into the quality of user experience. VISUAL EXPERIENCE METRICS SHOW WHAT A USER WOULD SEE AS THE PAGE RENDERS ON-SCREEN. THIS IS THE ULTIMATE EMPIRICAL MEASURE OF SPEED. A TRUE VIEW OF USER EXPERIENCE. THIS GROUNDBREAKING NEW TECHNOLOGY IMPLEMENTED INTO ADVANCED WEB PERFORMANCE TOOLS (LIKE ALERTSITE BY SMARTBEAR) PROVIDES METRICS ON KEY INDIVIDUAL MOMENTS IN THE USER EXPERIENCE. VISUAL EXPERIENCE METRICS ALLOW DEVOPS TEAMS TO...

DevOps folks need to take a CLOSER LOOK AT WHAT PERFORMANCE MEANS to the end user and what is most important when it comes to speed. YOU CAN'T OPTIMIZE YOUR BUSINESS WEBSITE BASED ONLY ON REALITY; PERCEPTION IS EQUALLY IMPORTANT. USER EXPERIENCE IS NOT A SINGLE METRIC. Visual experience metrics are not replacing technical performance metrics; THEY SIMPLY PROVIDE A MORE ROBUST AND EQUALLY IMPORTANT VIEW OF USER EXPERIENCE. Visual experience metrics are a new (AND VERY IMPORTANT) piece of the equation that makes up the real user experience. 89% ORGANIZATIONS THAT HAVE WEB MORE LIKELY TO PREVENT INCIDENTS MONITORING TOOLS IN PLACE ARE BEFORE USERS ARE IMPACTED *According to TRAC Research 70E "Perception is reality when it comes to a user's Web experience.' - Ken Godskind, VP of Monitoring Products, SmartBear Software INVEST INTO OPTIMIZATION EFFORTS THAT WILL ACTUALLY IMPROVE YOUR BOTTOM LINE!

We need to start evaluating what it is that users expect to see when they load a Web page. Instead of solely measuring the speed of the entire page, focus on the most important pieces. What are the mo...
