The Specification Artist

Helps people see the world in a new

way.

6

The Standards Engineer

Codifies well-understood phenomena

and

applies them to well-known problems

7

Specification vs. Standard

v Starts with a blank canvas • Starts with defined goal

v Free format

v Usually evolves

v Often describes an implementation

v Says many (perhaps different) things to many people

v Sometimes “you had to be there”

v Inspires

• Format dictated by Standard

• Evolution by formal means

• Implementation Independent

• Unambiguous

• All you need to know is right there (or in the references)

• Communicates

802.15.1 SDL

uDerived a picture of what the structure of the BT spec is in IEEE terms.

uHelped to uncover holes in existing spec

uEnables bench testing and validating of components

uProvides a common language between the SIG and the IEEE

uGeneration of TTCN from SDL is possible

14

Implications for the future of Standards

uNormative SDL makes an unambiguous Standard

uWorking SDL models can be used to extend currently working Standards, minimizing the danger of breaking the protocol

uSDL makes the relationship between Standards and Test Suites explicit

Future Bluetooth/IEEE Collaboration

uIEEE 802.15 continues to work with the Bluetooth Special Interest Groupn Submission of Erratan “Early” updates of the Spec from the SIG – current

version of Draft includes v1.1 Bluetooth Specificationn Plans for future revisions ofw Version 1.xw Future versions

uThere now is an overlap of “ownership” of the two documents.

IEEE 802 Standards Principals

uDue Process through established rules and procedures

uConsensus highly desired, near unanimity is generally the rule

uOpenness where all individuals, world-wide, have access to the process

uBalance maintained by having balloting group include both developers and users

uRight to Appeal both procedural and technical issues at any time during the process
