12、national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Inte
13、rnational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those int
14、ended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

The SOW shall define the customer management requirements and activities
19、to satisfy the contract requirements. The SOW is the baseline of business agreement to develop the management requirements of a space system.This International Standard contributes to the satisfaction of quality and on time delivery of space systems, subsystems and components.This International Stan
20、dard provides the significant process and tools to meet the contract management requirements and acts as a supplement to ISO 14300-1.This International Standard helps to develop a statement of work applicable to all types of space systems, all product elements, and projects.

31、es what is to be delivered and to be done by the supplier in terms of requirements, not how to accomplish the work by supplier.The SOW is a valuable tool to capture the work to be done by the supplier for contract management.The SOW is one of the attachments in the business agreement and is consiste
32、nt with all sections of the business agreement.The SOW is the major document in the business agreement which forms the basis for effective management of a project. A SOW serves as the standard for determining if the supplier meets the stated management requirements.The requirements in the SOW are st
33、ated in terms of results needed rather than how to proceed in order to achieve those results.5 Process for establishing a statement of work5.1 GeneralA systematic process for SOW development begins with an analysis of what work is to be performed and the work breakdown into components. It ends with
34、a clear description of output requirements.The process for establishing the SOW should be implemented during Phase A of the systems engineering life cycle.2 ISO 2014 All rights reservedBS ISO 17255:2014ISO 17255:2014(E)5.2 Prerequisite for establishing a statement of workA team shall be set up as th
35、e prerequisite for establishing the SOW. The team should:a) Use work breakdown structure (WBS) in developing the SOW. The requirements for WBS are defined in ISO 27026.b) Ensure that only those tasks which add value to the project are included in the SOW.c) Identify the required documents which prop
36、erly authorize the project and define its basic objectives.d) Prepare a bibliography referring to the specific portions of all applicable specifications and standards with which the project must comply.e) Categorize the work described by WBS into that which will be done by the customer and that whic
37、h needs to be contracted.f) Identify all organizations and persons who will participate in preparing the SOW, and determine the participants areas of responsibility.g) Identify the work and resources which the customer needs to provide during the process that the supplier accomplishes the work.h) Pr
38、epare the SOW following the requirements of this International Standard.5.3 Steps for establishing a statement of workThe process for establishing the SOW should comprise 8 steps. Steps 1 to 4 establish a Preliminary SOW which is used for invitation to tender as a part of the Request For Proposal (R
39、FP). Steps 5 to 8 establish a Final SOW which is used for developing as a part of the business agreement. The 8 steps are as follows:1) Step 1:prepare for establishing SOW;2) Step 2:structure the management requirements;3) Step 3: assess the management requirements;4) Step 4: establish preliminary S
40、OW;5) Step 5: negotiate the management requirements in preliminary SOW with supplier;6) Step 6: adjust and complete the management requirements;7) Step 7: agree on the management requirements;8) Step 8: issue the final SOW.The steps for establishing the SOW are summarized in Figure 1.The outcome of
41、this process is an agreed set of management requirements issued by the customer and to be included in the business agreement for development.

45、 a summary of the procedural steps for preparing a SOW (see Figure 2):a) Establish a preliminary scope statement according to the mission statement and need analysis (i.e. the purpose or objective of procurement): Identify the objective or purpose of the procurement; Describe the work to be performe
46、d; Define the magnitude of work to be performed; Define the boundaries of performance and responsibilities.b) List the tasks to be performed: Group similar and related tasks; Categorize tasks as either major or sub-tasks; Add any additional task.NOTE Take care not to overly constrict the methods whi
47、ch the supplier must use to perform the work.c) Organize the tasks in logical sequence: Chronological order, time-phase, discipline; Ensure that each task required meets each mission requirement; Ensure that no unnecessary or repetitive tasks are included.d) Identify the output (Required results or
48、deliverables): Identify required results or deliverables (products, services, meetings, reports); Ensure that each output has been verified to meet the requirements.e) Identify the input: Identify the required resources for each task (may be labour, equipment and material, documentation); Identify a
49、ny operating restrictions or procedures.f) Identify the time limit or frequency of the deliverables referring to lessons learned and historical data.g) Develop the parameters for acceptable quality referring to lessons learned and historical data: Develop a performance standard or acceptance criteria; Include elements such as “what”, “when”, “where”, “how many times”.h) Determine how to monitor the deliverables referring to lessons learned and historical data: Appropriate for the contract; E
