What are the key qualities of a REQUIREMENT? - (CORRECT ANSWER)- It must be properly DEFINED.
- It can be MODELLED (at least for functional reqs).
What is "Natural Language" regarding requirements? - (CORRECT ANSWER)- It is used for writing
requirements
- Requirement = natural language + diagrams + tables
- Writing requirements this way allows it to be understood by both users and customers
Ex:
The system shall measure the blood sugar and deliver insulin, if required, every 10 minutes. (Changes in
blood sugar are relatively slow so more frequent measurement is unnecessary; less frequent
measurement could lead to unnecessarily high sugar levels.)
What are the advantages of "Natural Language"? - (CORRECT ANSWER)- well-established practice (been
used forever)
- flexible (requirement is easy to write out)
What are the disadvantages of "Natural Language"? - (CORRECT ANSWER)- lack of clarity (more precise =
harder to read the document)
- requirement confusion (functional and non-functional requirements get mixed up)
- requirements amalgamation (several different requirements may be expressed together)
