The W3C Quality Assurance Working Group has published the second public working draft of the QA Handbook. According to the abstract, "The QA Handbook (QAH) is a non-normative handbook about the process and operational aspects of certain quality assurance practices of W3C's Working Groups, with particular focus on testability and test topics. It is intended for Working Group chairs and team contacts. It aims to help them to avoid known pitfalls and benefit from experiences gathered from the W3C Working Groups themselves. It provides techniques, tools, and templates that should facilitate and accelerate their work. This document is one of the QA Framework (QAF) family of documents of the Quality Assurance (QA) Activity. QAF includes the other in-progress or planned specifications: Specification Guidelines (in progress), and Test Guidelines."
The W3C Quality Assurance (QA) Activity has also published a revised working draft of the QA Framework: Specification Guidelines. Quoting from the abstract, "A lot of effort goes into writing a good specification. It takes more than knowledge of the technology to make a specification precise, implementable and testable. It takes planning, organization, and foresight about the technology and how it will be implemented and used. The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance for a specification. Additionally, it addresses how a specification might allow variation among conforming implementations. The document is presented as a set of guidelines or principles, supplemented with good practices, examples, and techniques."
Finally, the W3C QA Group has published the first working draft of Variability in Specifications:
This document details and deepens some of the most important conformance-related concepts evoked in the QA Specification Guidelines, developing some of the analysis axes that need to be considered while designing a specification and providing advanced techniques, particularly for dealing with conformance variability and complexity.
