Whether it is to guarantee passenger safety, ensure driver comfort or efficiently inform customers about their journey, the slightest bug is excluded in this multitude of data.\u00a0To better anticipate what could go wrong with its car ranges, the prominent French car manufacturer has been using Expleo&#8217;s expertise in data science, textual analysis, and <a href=\"https:\/\/expleo.com\/global\/en\/services\/product-engineering\/\">RAMS (Reliability, Availability, Maintainability &amp; Safety)<\/a> engineering to conduct an extensive 360\u00b0 study of all reported quality returns.\u00a0\u00a0Faced with thousands of after-sales exchanges every month, analysing this great quantity of data is a challenge.

The team included the RAMS engineers in charge of studying the operating safety of the targeted vehicle ranges; the data scientists specialising in natural language processing to better analyse the numerous written information sources; and the data analysts in charge of working on the design of the data visualisation dashboards.\u00a0 AFor the time being, the solution deployed by Expleo covers our client&#8217;s vehicle fleet in France.\u00a0 For this project Expleo relies on the combination of the Python programming language, a data analysis method based on natural language processing (NLP), as well as the TIBCO Spotfire, R Shiny or Dash data visualisation platforms.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-61bb8fb gg-font-v8 gg-custom-dark-purple-color elementor-widget elementor-widget-heading\" data-id=\"61bb8fb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Outcome - Improved understanding of customer's feedback <\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c288712 gg-font-v9 gg-class-for-iphone8 elementor-widget elementor-widget-text-editor\" data-id=\"c288712\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Ehe first significant benefit for our client is a drastic reduction in the time and technical or human resources required to analyse its field reports.\u00a0For example, several days of manual transcription are reduced to just a few minutes of data processing. Thanks to Expleo\u2019s NLP algorithms sophistication, false alarms about incapacitating breakdowns have been significantly reduced in keyword searches.\u00a0\u00a0Following a specific test phase, Expleo&#8217;s algorithms can now reduce the readback rate by 50%, with a margin of error of only 5%. The advantage was quickly noticeable for our client&#8217;s quality department on a word like &#8216;traffic light&#8217;, whose many possible interpretations (low beam, positional light\u2026) could lead to a lesser relevance in the diagnosis.\u00a0Beyond this example, the correct diagnosis is, of course, the overall objective. And the results are more than notable there, too, with the combination of data intelligence and data visualisation tools. Thanks to the dashboards set up by Expleo, processes have been automated, and correlations between the information collected can be highlighted faster.\u00a0Currently, Expleo&#8217;s algorithms classify potential quality problems in 600 failure scenarios with an accuracy of at least 80%.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-7a3e43fe gg-quotation gg-container-small-ptb-72 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"7a3e43fe\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1f224d58\" data-id=\"1f224d58\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-20bd6f89 elementor-blockquote--skin-clean elementor-blockquote--align-left elementor-widget elementor-widget-blockquote\" data-id=\"20bd6f89\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"blockquote.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<blockquote class=\"elementor-blockquote\">\n\t\t\t<p class=\"elementor-blockquote__content\">\n\t\t\t\tWith the automation, comfort, and speed of use of the Expleo solution, our client's quality teams benefit from improved reproducibility of the identification criteria for their field reports.
