In my case, they find data that&#8217;s so wonky that it does something weird because it&#8217;s at the edges of things. So out of that you think, \u201cHmm, I didn&#8217;t prepare for that one,\u201d but you get better at Failure Modes and Effects Analysis as you go along.<\/p>\r\n<p>&#8220;So here&#8217;s the thing: All of the tools that are out there to help you design a great product will help you a lot. I just saw an article I think it was in ASQ\u2019s Quality Progress magazine: the PPAP application reduced the number of defects by 40 percent in the final launched product. Now there&#8217;s still 60 percent left, but that&#8217;s another story\u2026 but that&#8217;s dramatic improvement. Wouldn&#8217;t you want that in something new that you&#8217;re building? Sure you would, all right?<\/p>\r\n<p>&#8220;So this is the thing, though: it&#8217;s not going to survive contact with the end user. Have you seen all the various recalls on airbags and things like that? Guess what? You&#8217;re not going to survive contact with the end user.<\/p>\r\n<p>&#8220;So that&#8217;s my Improvement Insight for this week: Design it as best you can, but prepare for whatever shows up at the end because it&#8217;s going to maybe be different than you could have imagined. Let&#8217;s create a hassle-free America; let&#8217;s create a hassle-free world. Go out and improve something this week.&#8221;<\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>No matter how well you design something using DFSS, users will find ways to use it or break it in ways you can&rsquo;t imagine! &ldquo;In Six Sigma we have all these tools for designing for Six Sigma, so we have Quality Function Deployment and Failure Modes and Effects Analysis and all this other stuff; PPAP [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":4799,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[290,3,7],"tags":[276,166,118,168,140,170],"class_list":["post-2382","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-improvement-insights","category-lean","category-six-sigma","tag-agile-lean-six-sigma","tag-lean","tag-lean-six-sigma","tag-qi-macros","tag-quality-improvement","tag-six-sigma"],"_links":{"self":[{"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/posts\/2382","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/comments?post=2382"}],"version-history":[{"count":6,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/posts\/2382\/revisions"}],"predecessor-version":[{"id":2428,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/posts\/2382\/revisions\/2428"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/media\/4799"}],"wp:attachment":[{"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/media?parent=2382"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/categories?post=2382"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.qimacros.com\/lean-six-sigma-blog\/wp-json\/wp\/v2\/tags?post=2382"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
