37、he Functional Need Analysis, Functional Need Expression and Functional Performance Specification and determines the compliance requirements for the parties involved. It extends the generic standard on Value Management, EN 12973. It separately presents the requirements applicable to the processes tha

38、t have to be implemented and those applicable to the deliverables derived from these processes. 0.2 Basis In highly competitive markets, the durability and the development of organisations depend on their capacity to provide competitive products which are best suited to satisfy the need, whether exp

39、ressed or implicit, of the users. The statement of the need in a functional form, i.e. in terms of purpose, without reference to solutions (technical, administrative, procedural, and organisational, etc.) likely to satisfy it, ensures there is every chance that competitive and innovative solutions w

40、ill emerge at the design stage. The statement of the need in a functional form is essential. It permits the expression of the: reference of this need in validated terms (in terms of obligations, expected services, rather than in terms of means) which can be used to control the evolution of this refe

41、rence at the later stages of the products life; level of importance of the main requirements which make up the cost of a product. Using a structured need statement approach in a functional form promotes the: offer of competitive and innovative products; mobilisation of all the interested parties to

42、obtain a unified expression of the need which can be used at each step - from the development to the evaluation of offers satisfying the same need; dialogue between the partners, while respecting the responsibilities of each partner and with a clearer relationship between the customer and the provid

43、er. This European Standard addresses the quality of specification under the responsibility of the enquirer, the handling of the customer/provider relationship and the search for the optimum solution in relation to the expressed need. The standard also addresses the performance levels and the grade o

44、f quality required by the enquirer. 0.3 Organisation and presentation of processes and deliverables Figure 1 below shows schematically the relationship between the three key processes (Functional Need Analysis (FNA) process, the Process for drawing up the Functional Performance Specification (FPS),

45、and the FPS utilisation process: The Functional Need Analysis (FNA) process: this enables the defining of the result named Functional Need Expression (FNE). The process for the drawing up of the Functional Performance Specification (FPS) from the FNE: this process generates a document (FPS) used wit

46、hin the framework of external enquiries, calls for tenders, the Design To Objective (DTO) approach, or internally by certain organisations.
