12、 is a document through which a customer expresses his needs (or those that he is responsible for expressing) and the related environment and constraints in terms of technical requirements. The technical requirements contained in the TS allow for potential suppliers to propose the best technical and
13、programmatic solutions. NOTE The intention of the technical requirements specification is not to assume or refer to specific solutions. The TS is the technical reference for the qualification of the design and for the acceptance of the end product. In that scope, the technical requirements contained
14、 in the TS are subject to the agreed change process defined in the business agreement. They are attainable and verifiable. NOTE The change process itself can change in between project phases (Phase 0, A, B, C/D). 4.2 TS content A technical requirements specification is typically composed of three ma
15、jor sets of information: General information related to the context of the document (e.g. administrative information, normative documents and informative documents); General information related to the context of the project, the product or system; Technical requirements (described in clauses 6 and 8
16、). DIN EN 16603-10-06:2014-11 EN 16603-10-06:2014 (E)12 The specification provides the general information related to its context: Administrative information: to provide all the information regarding, for example, the owner, status, identification, distribution list, and management rule; Scope: to d
17、efine without ambiguity the subject of the TS and aspects covered, thereby indicating limits of applicability; References: to list all the normative (applicable) documents and standards, with titles, issue revision, and dates that are referred to in the TS; Terms, definitions and abbreviated terms:
18、to list the specific terms and abbreviated terms used in the TS. It also provides general information related to the context of the project, product or system: to provide a clear and rapid understanding of the project and the main needs or mission statements; to give indications of the market as add
19、itional information, as well as information about the context of the project and the objectives (situation of the project in a larger programme, further developments); to provide information on the environment and its constraints; to detail the different situations of the product or system life cycl

The suc
21、cessive states of a product are characterised by initially a “high level” (e.g. rather of functional type) definition of needs / requirements (e.g. at Phase 0), evolving progressively to a more precise (e.g. at phase B) or frozen (e.g. Phase C, or procurement of an equipment) definition of all requi
22、rements. The procurement of products is governed by business agreements between two parties - the customer and the supplier. At any intermediate level, the supplier of an item acts as customer in specifying components towards its suppliers. A business agreement results from a process between a custo
23、mer with a problem to solve, and a supplier with potential solutions. This results in a set of requirements that engages both parties. The list of technical requirements constitutes an important part of the business agreement and is adapted to the nature of the expected outcome. This list is contain
24、ed in the technical requirements specification. 5.2 Process for establishing a technical requirements specification The process to establish the technical requirements specification during Phase 0 of a project starts with the identification and evaluation of the different possible concepts to establ
