1、,Appendix A,Appendix A,Product Category Tables Release 4.0The Product Category Tables listed below are part of the TL 9000 standard.This is Release 4.0 of Appendix A of the Measurements Handbook.It may beused effective February 1,2007 for submitting TL 9000 data dated January2007 forward and must be
2、 used for submitting data dated July 2007 forwarduntil superseded by the next revision.Each revision is an approved release by the QuEST Forum and is identified bya release number.The latest release of these tables and their effective datesare available via the TL 9000 website and shall be used in c
3、onjunction withregistrations per the rules noted in 4.1.1.Organizations shall classify their products and report measurements according tothe product categories listed in Table A-1.The Measurement Applicability Table(Normalized Units),Table A-2,lists specific measurements that apply to eachcategory

6、 shall not classify a product in multiple productcategories.Therefore,any product from an organization must beclassified in exactly one product category.3)General-purpose products,such as computers,shall be classified byspecific function,e.g.,signaling,when provided as a system designed forthat func
7、tion.Otherwise,they shall be classified in a separate category,for example,Common Systems-Computers,designed for the general-purpose product.4)A product shall be classified according to its primary function.Forexample,a digital transmission facility product with performancemonitoring will be classif
8、ied as a transmission product instead of anoperations and maintenance product.5)The standard for classification is the product category,not the possibleuses for the product.For example,if a product classification falls in theOutside Plant category,all products that are consistent with that categoryw
9、ill be classified as such,even if the exact same product is sometimesused in the customer premises and even if a particular organizationsproduct is sold primarily into the customer premises market.TL 9000 Quality Management System Measurements Handbook 4.0,Appendix A,Appendix A,c)Principles for Cons
10、truction of the Product Category Table,1)Product categories shall be defined so that they can be clearly assigned,within a hierarchy of classification.,2)There are well-established rules for classification.,3)Product categories should not be separated artificially if they can be,logically aggregated
11、.,4)Product categories should have clear definitions,which lend themselves,to unambiguous interpretation.,5)For each category,the level to which measurements may be aggregated,shall be defined.,6)Each product category specification shall consist of standard elements.7)The placement of the product in
12、 the hierarchy will reflect the dominant,use of the product.,8)Terminology used shall reflect standard technical meanings;whereverpossible aligned to relevant standards such as ITU-T,ETSI,ANSI,etc.,TL 9000 Quality Management System Measurements Handbook 4.0 Appendix A,A-2,1,1.1,1.2,Note 1,Note 2,Not
