Appendix A Product Category Tables Release 3.6

This document is a revision to Tables A-1, A-2 and A-3 of AppendixA of TL 9000 Quality Management System MeasurementsHandbook, Release 3.5. However, the tables shown here aresubject to revision and may have changed. See the QuEST Forumweb site (http://www.questforum.org/) for the latest version. Thelatest version shall be used in conjunction with registrations.

Release 3.5 or Release 3.6 of the Product Category Tables may be usedfor submitting April, May, and June 2004 TL 9000 measurement data.The software to support Release 3.6 submissions will be available in July2004. TL 9000 data for July 2004 and later must be reported underRelease 3.6 until the next release. A summary of the changes in this

version of the Tables is available at the above web site.

Organizations shall classify their products and report measurementsaccording to the listed product categories. The Measurement

Applicability Table (Normalized Units), Table A-2, lists specificmeasurements that apply to each category as well as the normalizedunits and other information necessary for compiling measurementreports.

b) Product Category Definitions

Table A-1 contains definitions of product categories to be used byorganizations in categorizing their products.

c) Rules for Classification of Products

1) An organization will not be required to report measurements for agiven product in multiple product categories. Therefore, any

product from a given organization must be classified in exactlyone product category.

2) General-purpose products, e.g., computers, will be classified byspecific function, e.g., signaling, when provided as a systemdesigned for that function. Otherwise, they will be classified in a


3/57

Appendix A


A-2

separate category, e.g., Common Systems-Computers, designedfor the general-purpose product.

3) A product will be classified according to its primary function. Forexample, a digital transmission facility product with performancemonitoring will be classified as a transmission product instead ofan operations and maintenance product.

4) The standard for classification is the product category, not thepossible uses for the product. For example, if a productclassification falls in the Outside Plant category, all products thatare consistent with that category will be classified as such, evenif the exact same product is sometimes used in the customerpremises and even if a particular organizations product is soldprimarily into the customer premises market.

d) Principles for Construction 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 canbe logically aggregated.

4) Product categories should have clear definitions, which lendthemselves to unambiguous interpretation.

5) For each category, the level to which measurements may beaggregated shall be defined.

6) Each product category specification shall consist of standardelements.

7) The placement of the product in the hierarchy will reflect thedominant use of the product.

Category Code Category Name Definition Examples

1 Switching Equipment for the physical or virtual interconnection ofcommunication channels in response to a signaling system. Theswitching category is broadly defined to include packet or circuitswitched architectures.

1.1 Circuit Switch Equipment for the termination of subscriber lines and/or trunk linesand the dynamic interconnection of these ports or channels in adigital transmission facility. A circuit switch establishes a dedicatedcircuit, as opposed to a virtual circuit, in response to a signal. StoredProgram Control (SPC) is the most common type of switchingequipment used at end offices and tandem offices. These systems useeither analog or digital switching. The switching system used must havethe capability to send, receive and be actuated by signals, e.g., accessline signals, or inter-office in-band or common-channel signaling. Thiscategory includes all circuit switches regardless of transmission medium,i.e., wireline, or wireless.

2) Measurement Applicability Table (Normalized Units)

a) Measurements Without Normalization Factors

The measurements Fix Response Time (FRT), Overdue FixResponsiveness (OFR), and On-Time Delivery (OTD) areapplicable and required for ALL product categories, with the

exception of OTD for Customer Support Service (category 7.5)where resolution time is the service quality measurement. Themeasurements FRT, OFR and OTD do not require productspecific normalization. In the interest of saving space, they arenot listed in the following table, but data must be submitted foreach of these three measurements for all products. Use Table

A-2 to determine the normalization units and applicability of therest of the measurements.

b) Other Rules and References

i) Where the normalization factor is traffic capacity based, suchas DS1, OC-1, DSL or Terminations, the calculation shall bebased on the true usable traffic capacity. Equipment withinthe system used to provide protection for the main trafficpath shall not be included, as it does not add usable capacityto the system.

ii) Software measurements are based on the three mostdominant releases. % = 100 x Quantity Defective / TotalQuantity. % is applicable to Software Onlymeasurements.

iii) NA means the measurement is not applicable for theproduct category.

iv) None means that no common normalization factor hasbeen identified for the product category; however, data shallbe submitted for the measurement.

v) The column headings in Table A-2 are general descriptionscovering several sub-measurements in some cases. Forcross-references to the detailed descriptions of themeasurements elsewhere in this document, refer to themeasurement and sub-measurement symbols in Table A-6.

vi) A system, for the purposes of TL 9000 normalization factorcalculation, is defined as a collection of hardware and/orsoftware items located at more than one physical locationwhere all items are required for proper operation. No singleitem can function by itself.

vii) For some product categories it may not be clear what is tobe considered a unit. The following is added as an aid forthe listed categories:

7.6.1 total quantity of items procured

7.9 total quantity of items provided or supported

8.6.1 copies/licenses issued

8.6.2 simultaneous licensed users


36/57

Appendix A


A-35

c) Measurement Summary Listing

Table A-6 is a listing of the measurements included in thishandbook with the symbols used in data reporting, theapplicability to hardware, software, and/or services (H, S, V), anda reference to the table in this handbook with data reportingdetails. The symbols listed here are referenced by the

normalization unit and applicability table to clarify the generaldescriptions used as column headings.

Note 1 The information in this table may have changed. The latest release of this table and its effective date are available via the QuESTForum website (www.questforum.org).

Note 2 Measurements FRT, OFR & OTD are applicable and must be reported for all product categories except OTD for 7.5.Note 3 Product Categories listed inRED and italicizedwill be used for possible Data Aggregation only. Measurements must be submitted per the

lower Product Category listing.Note 4 If the normalization factor contains the word shipped, then the quantity shipped in the 12 months ending prior to the month being

reported shall be used.
