ANSI ASQ Z1.4-2008 PDF

The numbers, letters and terminology surrounding this table can seem intimidating at first. So importers often leave the details of understanding acceptable quality levels AQLs to QC professionals. This part of using the AQL sampling plan tables is easy— simply choose the lot size range containing your total order quantity. The inspection level you choose is a critical determinant of your ANSI sampling plan and the scope of your product inspection. So carefully consider your product quality standards, customer expectations and time and budget constraints when choosing an inspection level. This typically involves visually inspecting the product to look for quality defects and nonconformances, as well as conducting any on-site tests and checks that cover the main sample size.

It is intended to be a reference for both beginners in Six Sigma and those who are already knowledgeable about process improvement and variation reduction. The author has utilized feedback from Six Sigma practitioners and knowledge gained through helping others prepare for exams to create a handbook that will be beneficial to anyone seeking to pass not only the CSSYB exam but also other Six Sigma exams.

In addition to the primary text, the handbook contains numerous appendixes, a comprehensive list of abbreviations, and a CD-ROM with practice exam questions, recorded webinars, and several useful publications. Each chapter includes essay-type questions to test the comprehension of students using this book at colleges and universities.

Over these years, Govind has been a great source of expertise on lean and six sigma for me to consult. This comprehensive handbook reflects his experiences and insights on how to select and conduct a six sigma project successfully, and on how to make the process improvement sustainable after a project is done. The statistical examples given in the handbook are very informative and easy to understand.

It is indeed an excellent reference for anyone who is interested in process improvement. Tools and techniques appropriate for each DMAIC Phase are introduced with background to provide context and then well covered with how-to instructions and content-rich graphics as examples. I recommend it to anyone in search of a comprehensive handbook.
