5. Scope and Approach
Focuses on the way standards should be written to achieve technical quality
structure
expression of requirements
Based on good practice and use of real examples
Takes into account different deliverable types
Readability of the guidelines is very important
Complements, not replaces, other material such as the ETSI Drafting Rules, Rapporteur’s Guide, Validation Guidelines
Role of testing is addressed but not a guide on how to write a good test suite
Does not cover aspects such as IPR, voting, commercial drivers etc.
Not a guide on formal techniques as such but advice is given on when they may best be applied
