This trend can be observed mostly in Cloud-based services, or in the Cloud services themselves. If you\u2019re even a little bit interested in gaming, you\u2019ve noticed a swarm of \u201cearly access betas\u201d available on the market. As a feature-geek I can understand the drive behind this practice, but as a service manager I can\u2019t say I like it at all.<\/p>\n<p>Whether we discuss online games or business services, in my honest opinion, only fully featured and quality <a href=\"https:\/\/advisera.com\/20000academy\/iso-20000-documentation-toolkit\/?rel=service-design-build-and-transition-processes&amp;doc=test-plan\" target=\"_blank\" rel=\"noopener\">tested<\/a>\u00a0products should ever reach end users (customers). And, while the entertainment industry can be excused for diverging from good practices, enterprise-oriented service providers (e.g., Cloud) should not follow that path.<br \/>\n<div id=\"middle-banner\" class=\"banner-shortcode\"><\/div><script>loadMiddleBanner();<\/script><br \/>\n<div id=\"side-banner-trigger\" class=\"banner-shortcode\"><\/div><\/p>\n<h2 style=\"padding-top: 10px; padding-bottom: 10px;\">Service validation and testing purpose<\/h2>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"alignnone size-medium wp-image-4443\" src=\"https:\/\/advisera.com\/wp-content\/uploads\/sites\/6\/2015\/07\/Validation_and_testing-300x202.png\" alt=\"Validation_and_testing.png\" width=\"300\" height=\"202\" srcset=\"\/wp-content\/uploads\/sites\/6\/2015\/07\/Validation_and_testing-300x202.png 300w, \/wp-content\/uploads\/sites\/6\/2015\/07\/Validation_and_testing-272x182.png 272w, \/wp-content\/uploads\/sites\/6\/2015\/07\/Validation_and_testing.png 504w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><br \/>\n<em>Figure 1 &#8211; Validation and testing (1 &#8211; Plan &amp; design tests, 2 &#8211; Verify test plan, 3 &#8211; Prepare environment, 4 &#8211; Perform tests, 5 &#8211; Evaluate exit criteria and report, 6 &#8211; Test cleanup and closure)<\/em><\/p>\n<p>The purpose of the service validation and testing phase is to:<\/p>\n<ul>\n<li><strong>Plan<\/strong> and implement a structured validation and test process that will generate evidence that the service will support the customer\u2019s business within agreed service levels.<\/li>\n<li><strong>Provide quality<\/strong> assurance for a release and its components and service capability.<\/li>\n<li><strong>Identify <a href=\"https:\/\/advisera.com\/20000academy\/documentation\/risk-assessment-and-treatment\/\" target=\"_blank\" rel=\"noopener noreferrer\">risks<\/a><\/strong>, issues, and errors and eliminate them throughout Service Transition.<\/li>\n<\/ul>\n<p>How to manage service validation and testing is the topic of <strong>Validations and test management<\/strong> as shown in Figure 1: planning and managing\/controlling and then reporting on the activities that have taken place during all phases to ensure they are fit for purpose\/use.<\/p>\n<h2 style=\"padding-top: 10px; padding-bottom: 10px;\">Service validation and testing activities<\/h2>\n<p>There are many activities within this process, all logically structured and designed with <strong>repeatability<\/strong> in mind:<\/p>\n<ul>\n<li><strong>Validation and Test Management<\/strong> (mentioned earlier)<\/li>\n<li><strong>Planning and Design<\/strong> \u2013 (Figure 1, #1) Test planning and design activities take place in the early stages of the Service Lifecycle.
