The validation process usually involves several steps, which can be described as follows:<\/p>\n<ol>\n<li><strong>Definition of the requirements:<\/strong> The validation process begins by defining the requirements for the product or service to be validated. This may include, for example, the review of technical specifications, standards, customer requirements and regulatory requirements.<\/li>\n<li><strong>Planning:<\/strong> The next step is to create a validation plan that defines the objectives, scope, timeframe, responsibilities, resources and verification and validation techniques for the validation process. This plan serves as a roadmap for the validation process.<\/li>\n<li><strong>Carrying out verifications and validations:<\/strong> The validation process involves carrying out verifications and validations to ensure that the product or service meets the requirements. Verifications include, for example, tests, inspections and analyses to ensure that the product or service is correct and complete. Validations include, for example, checking whether the product or service meets the requirements and fulfills the intended purpose.<\/li>\n<li><strong>Reporting:<\/strong> Once the validation process is complete, a report is produced summarizing the results of the validation process. The report usually contains information on the verifications and validations carried out, the results, the deviations and the corrective measures.<\/li>\n<li><strong>Follow-up:<\/strong> After the validation process has been completed, follow-up measures may be necessary to ensure that the product or service continues to meet the requirements. This can include, for example, monitoring trends, conducting reviews or carrying out revalidations.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"Best_practices_to_ensure_successful_validation\"><\/span>Best practices to ensure successful validation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Some best practices for using verification and validation in the singular and plural are:<\/p>\n<ul>\n<li>Clearly define what verification and validation mean in context<\/li>\n<li>Ensure that all steps in the validation process are clearly defined and documented<\/li>\n<li>Check whether the verification and validation processes meet the requirements<\/li>\n<li>Involvement of experts and stakeholders in the validation process<\/li>\n<li>Continuous monitoring of data using automated tests and monitoring<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Why_is_data_validation_so_important_in_software_development\"><\/span>Why is data validation so important in software development?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Validation<\/strong> is therefore of <strong>central importance<\/strong> in the <strong>qualitative improvement of software <\/strong>.<\/p>\n<p><strong>Data validation<\/strong> is therefore essential during the development and use of software.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Validate_data_from_the_first_prototype_to_the_current_software_release\"><\/span>Validate data from the first prototype to the current software release<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>According to this understanding, validation must be continuous over the entire development period in all software releases. <a href=\"https:\/\/rock-the-prototype.com\/wiki\/release\/\" target=\"_blank\" rel=\"noopener\"><br>\n<strong>software releases<\/strong><br>\n<\/a> and with the start of the first <a href=\"https:\/\/rock-the-prototype.com\/en\/prototypes\/\" target=\"_blank\" rel=\"noopener\"><br>\n<strong>prototypes<\/strong><br>\n<\/a> from the beginning.<\/p>\n<p>This is the only way to ensure that the software can later be used without errors.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Potential_of_data_validation_to_increase_software_quality\"><\/span>Potential of data validation to increase software quality<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The potential and positive effects of early detection of problems and errors are correspondingly high. However, due to time and cost constraints, which practically all software development processes are subject to, it is not possible to validate as extensively as desired. The aim must therefore be effective and efficient validation based on an understanding of the system and model. Unfortunately, from today&rsquo;s perspective, validation is neither comprehensively formalized nor universally valid and consistently methodologically supported. Rather, validation is essentially experience-based and characterized by the individual skills of the software developers as well as discipline-, task- and application-specific.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"With_methodology_and_standardized_analysis_for_established_data_analysis\"><\/span>With methodology and standardized analysis for established data analysis<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>By applying methodical principles as well as continuous and standardized documentation and analysis, routines and models can be reused and specific reference processes can be derived that can be used for future software developments.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Practical_examples_of_data_validation\"><\/span>Practical examples of data validation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Validation provides a statement as to whether a created model adequately describes a real system and thus also fulfills any unspecified requirements.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Validation_Are_specified_requirements_fulfilled\"><\/span>Validation: Are specified requirements fulfilled?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>To illustrate this, here is a current example of <strong>problems<\/strong> that have occurred in the past <strong>with the air conditioning systems of the ICE fleet<\/strong>: At very high temperatures, the air conditioning systems of the ICE3 trains repeatedly fail. Deutsche Bahn ultimately confirmed to the Federal Railway Authority that the cooling system for the older ICE3 fleet was only specified for outside temperatures of up to 32 &deg;C.<\/p>\n<p>The specified requirement &ndash; cooling up to an outside temperature of 32 &deg;C &ndash; was met and certainly verified. However, it appears that it has not been conclusively determined whether this requirement also corresponds to customer needs over the useful life, i.e. whether it is valid.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Initiate_feature_requests_and_optimization_based_on_validated_data\"><\/span>Initiate feature requests and optimization based on validated data<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>As a consequence and countermeasure, today&rsquo;s systems are designed for outside temperatures in the range of 40 &deg;C and are therefore better suited to the changes in climatic conditions over the past 20 years. In industrial practice, the term &ldquo;safeguarding&rdquo; is often used. This summarizes all test activities of a development project, from material testing to test drives or endurance tests.<\/p>\n<p>Air conditioning systems are also software-controlled components, so the example provides a practical and easy-to-understand example of the central importance of validation.<\/p>\n<p>With the <a href=\"https:\/\/rock-the-prototype.com\/algorithmen\/clustering-algorithmus\/\" target=\"_blank\" rel=\"noopener\"><br>\n<strong>clustering algorithm<\/strong><br>\n<\/a> you will find an <strong>algorithm-based<\/strong> and<strong> concrete solution<\/strong> on how to validate data.<\/p>\n<\/div><a class=\"fusion-modal-text-link\" data-toggle=\"modal\" data-target=\".fusion-modal.Spotify - ENGL - Episode 7 - Agile Testing - The Key Role for Successful Software Development - Rock the Prototype Podcast\" href=\"#\"><iframe class=\"lazyload\" style=\"border-radius: 12px;\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27100%27%20height%3D%27352%27%20viewBox%3D%270%200%20100%20352%27%3E%3Crect%20width%3D%27100%27%20height%3D%27352%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-orig-src=\"https:\/\/open.spotify.com\/embed\/episode\/47bnghLFREAGn0IhYkGzLB?utm_source=generator\" width=\"100%\" height=\"352\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/a>\n<\/div><\/div><\/div><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-2 fusion-flex-container has-pattern-background has-mask-background nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"--awb-border-radius-top-left:0px;--awb-border-radius-top-right:0px;--awb-border-radius-bottom-right:0px;--awb-border-radius-bottom-left:0px;--awb-flex-wrap:wrap;\"><div class=\"fusion-builder-row fusion-row fusion-flex-align-items-flex-start fusion-flex-content-wrap\" style=\"max-width:1144px;margin-left: calc(-4% \/ 2 );margin-right: calc(-4% \/ 2 );\"><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-1 fusion_builder_column_1_1 1_1 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:100%;--awb-margin-top-large:0px;--awb-spacing-right-large:1.92%;--awb-margin-bottom-large:0px;--awb-spacing-left-large:1.92%;--awb-width-medium:100%;--awb-order-medium:0;--awb-spacing-right-medium:1.92%;--awb-spacing-left-medium:1.92%;--awb-width-small:100%;--awb-order-small:0;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-column-has-shadow fusion-flex-justify-content-flex-start fusion-content-layout-column\"><a class=\"fusion-modal-text-link\" data-toggle=\"modal\" data-target=\".fusion-modal.Rock the Prototype - Software development &amp; Prototyping Podcast iTunes\" href=\"#\"><iframe id=\"embedPlayer\" style=\"width: 100%; max-width: 660px; overflow: hidden; border-radius: 10px; transform: translateZ(0px); animation: 2s ease 0s 6 normal none running loading-indicator; background-color: #e4e4e4;\" src=\"https:\/\/embed.podcasts.apple.com\/us\/podcast\/rock-the-prototype-software-development-prototyping\/id1684835330?itsct=podcast_box_player&amp;itscg=30200&amp;ls=1&amp;theme=auto\" height=\"450px\" frameborder=\"0\" sandbox=\"allow-forms allow-popups allow-same-origin allow-scripts allow-top-navigation-by-user-activation\"><\/iframe><\/a><\/div><\/div><\/div><\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Validation is a central activity in data processing.
