« Ce que l'on conçoit bien s'énonce clairement, et les mots pour le dire arrivent aisément. » Nicolas Boileau L’Art poétique “What is well conceived is expressed clearly, and the words to say it come easily. ” “What is badly conceived is expressed gloomily, and the words to say it come painfully. ” Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 « Ce que l'on conçoit mal s'énonce obscurément, et les mots pour le dire arrivent péniblement. » 8

3 Before starting writing the technical specification…
CERN — 2016 -11 -22 Technical auditing process Purchasing Supplies — Technical Specification Writing 22
Before starting writing… • Collect needs • Confirm constraints (incl. Safety constraints) • Agree supply approach (COTS or build-to-print or functional specification) • Agree supply scope Information gathering Document writing t Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 (pure supply, type of design, type of tests and QCs, installation works, commissioning, maintenance, dismantling, disposal…) 23
4 The writing style Requirement writing
The Writing Style Simplicity • Sentences short and simple • The reader is a technical person CERN — 2016 -11 -22 • Not trying for the Pulitzer Prize! Purchasing Supplies — Technical Specification Writing 25
The Writing Style “Shall” vs. “Will” • “Shall” is used to express a binding requirement • “Will” is used to express • “Should” “may” or “must” Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 a declaration of purpose 26
• “The contractor shall…” • “The supply shall…” • “CERN will…” Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 The Writing Style “Shall” vs. “Will” 27
The Writing Style Active voice Passive voice promotes ambiguity and leads to needlessly complex sentences. Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 Use active voice, not passive. 28
The Writing Style Ambiguities “Flying aircraft may be hazardous. ” CERN — 2016 -11 -22 “Flying” may act as a noun, an adjective, or a verb! Purchasing Supplies — Technical Specification Writing 29
The Writing Style Slash Mark “ / ” It’s the contractor who gets to decide which word is proper! Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 Dictionary “an oblique stroke used between two words to show that the appropriate one may be chosen to complete the sense of the text. ” 30
5 Some typing rules Appropriate use of the uppercase, and of the space
• Same rules throughout the TS • Same font throughout the TS • Avoid using uppercase • Maximum three levels of headings Purchasing Supplies — Technical Specification Writing CERN — 2016 -11 -22 Some Typing Rules Coherency 32
