Making Better Standards Steve Randall, STF217 or You’ve read the book now see the web site!
In the beginning . . . …was The Word
How did it start? • In 1994 MTS was generally viewed as ‘Academic’ • Output from MTS was becoming more practical with guides rather than strict rules • Something was needed to get these guides used and to improve the MTS image • PT69V set up to promote new methodologies • The “Making Better Standards” book was the outcome
Why “Making BETTER Standards”? • This is not the best wording. The implication is that our standards aren’t so hot and need improving! • Alternatives could have been: • Making Even Better Standards • Making Good Standards • Making The Best Standards • Making High Quality Standards • Editorially, “Making Better Standards” sounded right • Now we are stuck with it!
So Why Bother with an Update? • The MBS book was a remarkable success • Sent to all members • Demand means no spares left in ETSI now • Even hardened standards writers STILL use it - and are prepared to admit it! • BUT . . . . It is out of date now! • Based on MTS Rules rather than Guidelines • Reflects a much stricter regulatory regime in Europe • No Interoperability Testing • No TTCN-3 • No Descriptive SDL • No UML • Nothing substantial on MSC and ASN.1
MBS 2 • New and revised guidelines available • Different thinking on the role of MTS • New and improved specification languages available • Changed emphasis on conformance testing • Increased emphasis on interoperability testing • Testing and regulation not so closely coupled • What about publishing on a web site?
Why a Web Site? • More Hi-Tech than a book – the right image for ETSI • Lower cost Publication • Easier to search and navigate • Much easier to maintain • Available to a much wider audience • Distribution on CD if something “physical” needed • Simpler language is possible And anyway, why NOT a web site?!!
So What’s On It? • Introduction • Market Expectations • What Makes a Standard “Better” • Planning • Non-behavioural Standards • Protocol Standards • Using Specification Languages • Test Specifications • Validating Standards • European Regulatory Regime
Introduction • Introduction to the MBS site • How to use the MBS site • Simple guide to navigating MBS • Introduction to standardization • What to standardize? • Why Standardize?
Market Expectations • What is “The Market” in standardization terms? • Market factors affecting the success of a standard
What Makes a Standard “Better” • Characteristics of a good standard • Accurate and complete technical content • Standard is easy to read • Clear and unambiguous requirements
Planning • Planning Validation and Testing activities • Which Validation method to choose • How much Validation to include in the plan • Estimating the effort involved • Building a plan • Some example scenarios
Non-behavioural Standards • Physical characteristics • Tolerances
Protocol Standards • Protocol engineering within a standards environment: • Layered modelling • Other modelling and visualization methods • 3 stage design approach
Using Specification Languages • SDL • Including Descriptive SDL • MSC • ASN.1 • UML • TTCN(-3)
Test Specifications • Conformance Testing • Interoperability Testing • Comparison of Interoperability and Conformance Testing • Development Cycle • Certification
Validating Standards • Validation methods • Walk-Through (Design Review) • Formal validation methods • SDL model simulation • SDL model exploration • Prototyping & Early Implementation • Test Development
European Regulatory Regime • R & TTE Directive and its implications for Operators and Manufacturers: • Harmonized Standards • Interface Descriptions • Declarations of Conformity • Other important Directives
Overall Approach • Original MBS book reproduced text from a number of standards and reports • MBS 2 gives limited introductory text then links to the necessary standards and guides
