Or are there other statistically valid ways to do this?<\/p>\n<blockquote><p>C<sub>pk<\/sub> is ideal for quickly measuring or communicating a single, overall metric that describes the capability of a process.\u00a0 But yes, there are other valid ways of assessing process capability.\u00a0 What is best\u009d depends on the situation.\u00a0 For example, another condensed method is to quantify capability using a Z metric.\u00a0 Or for a more detailed perspective, a control chart shows capability over time.\u00a0 Bottom line: the method you select should fit the level of analysis and level of communication needed for the situation at hand.<\/p><\/blockquote>\n<h2>Introducing Six Sigma to an Organization<\/h2>\n<p>Newbie said,<br \/>\nMay 27, 2007 @ 10:46 pm<\/p>\n<p>For an organization not ready yet for the rigor of Six Sigma, what do you suggest for more of a workout\u009d approach?<\/p>\n<blockquote><p>For an organization that says they&#8217;re not ready for the rigors of Six Sigma, I&#8217;m not apologetic. I tell them the rapid, planned, quantifiable returns of Six Sigma are reserved for those that are ready to take on the raised level of required discipline. That&#8217;s the organization&#8217;s choice. But let me put this in context: I strongly believe Six Sigma is NOT the appropriate starting point for most organizations. Even if they&#8217;re not ready for the rigor of Six Sigma, they still desire organization-wide improvement. As such, I usually introduce Lean to companies first\u201dwhich is something every company should be doing. There is no better practical and cultural foundation for sustained improvement than Lean. Then when isolated pockets in the organization or the organization as a whole is ready for more rigor (and more return), I introduce them appropriately to Six Sigma. But if the organization&#8217;s reception of Lean is lukewarm or the desire for improvement turns out to be localized, I scale back to a targeted workout\u009d approach.<\/p><\/blockquote>\n<h2>Recent Cynicism Toward Six Sigma<\/h2>\n<p>Ron said,<br \/>\nMay 26, 2007 @ 12:30 pm<\/p>\n<p>Craig, as a MBB myself (and former Motorolan) I wonder if you could comment on the recent struggles Six Sigma has met in the mainstream media\u00a6 it seems everyone from Qualpro to Dilbert is on the witch hunt. I am interested in your thoughts.<\/p>\n<blockquote><p>Persistent excellence places you in some peoples&#8217; crosshairs\u201djust ask the New York Yankees! I actually take this type of sniping, like from Mr. Adams (Dilbert), as a compliment; for the most part it&#8217;s good natured ribbing which confirms the speaker recognizes Six Sigma&#8217;s leadership position. At the same time though, there definitely are individuals and organizations within the realm of Six Sigma whose message or tactics provide justification for cynicism. I cringe at some of the stories I hear from the trenches. In the end, I try to value the Voice of the Customer\u201dwhether flattering or not\u201dand use that as data to improve.<\/p><\/blockquote>\n<p>Stay tuned&#8230;more tomorrow.<\/p>\n<!--CusAds0-->\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>Update: To read Craig Gygi&#8217;s responses, visit these two posts: Original Questions posed to Craig Gygi Craig Gygi answers Question on Process Capability Craig Gygi answers Question on Accelerated Life Testing On May 25, I announced a contest whereby the readers of shmula could enter and win a Six Sigma for Dummies Workbook.\u00a0 In the [&hellip;]<\/p>\n","protected":false},"author":12327,"featured_media":9723,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[17],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.0 -
