9、tandardization) is a worldwide federation of 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 ri
10、ght to be represented on that committee. International 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. Internationa
11、l Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
12、an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

14、ion Space systems are very complex, incorporating many different technologies. Space programmes can last for many years, progressing through several different stages from conception to disposal or other disposition. When a space programme advances from one stage to another, substantial changes in th
15、e type and amount of resources required can occur. In addition, there may be attendant risks to either the success of the project or to the well being of project equipment or to personnel. Well-regulated project reviews can be an important factor in ensuring that all factors are ready for these chan
16、ges, and that the risks are well understood and accepted. Use of this International Standard as a basis for the activities comprising a review, their necessary resources, controls, inputs and results is intended to enhance communication between different organizations that participate in a review pr
17、ocess, and to reduce the costs of planning and performing reviews.

18、ty, Thu Dec 20 02:56:21 GMT+00:00 2007, Uncontrolled Copy, (c) BSI 1 Space systems Project reviews 1 Scope This International Standard provides process requirements for project reviews as a set of required functions. The requirements and recommendations cover the function inputs, outputs, mechanisms
19、 and controlling conditions. It is intended for use in implementing the review requirements of ISO 14300-1, ISO 14300-2, ISO 15865 and such other space systems and operations standards that require formal reviews. This International Standard specifies the responsibilities of a review board and gives
20、 guidance concerning review board composition. This International Standard is applicable to reviews for a project at any level within a larger project, as well as for major milestone reviews at the top level of a major project. It is intended to be used either by an independent developer as a basis
21、for enterprise processes, or as a basis for an agreement between a supplier and a customer. This International Standard also provides normative descriptions of the kinds of reviews that are commonly useful in assuring the success of a space project. 2 Normative references The following referenced do
22、cuments are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 14300-1:2001, Space systems Programme management Part 1: Structuring of

27、t 3.6 project expert person well acquainted with the project status and documentation and highly qualified in some area of the technical content of the project review 3.7 project review team body consisting of project experts, charged with preparing all evidence for the review and formulating respon
28、ses to action items NOTE The best practice for conducting a review involves two separate teams of experts: the project review team and the review board (3.8). The project review team is composed of persons well acquainted with the project, and is responsible for assembling information concerning the
29、 actual status of the project. 3.8 review board body, organized into sub-entities, as necessary, consisting of a review board chairperson or delegated person and review board members, charged with evaluating the evidence of project status, along with identifying issues and necessary corrective actio
30、ns, to determine that the objectives and success criteria of a review milestone have been met NOTE The purpose of the review board is to prepare an objective evaluation of the project status. Achievement of an objective evaluation is aided by use of independent experts who have no prior association
31、with the project and no personal conflict of interest with respect to the outcome of the review. 3.9 review board chairperson leader of the review board, who approves the review policy, objectives, success criteria, organization of the review board and nomination of review board members 3.10 review

34、7, Uncontrolled Copy, (c) BSI 3 NOTE The flow of activities to achieve this purpose is one of identifying the participants and the plan, preparing the evidence of the project status, evaluating the evidence relative to milestone criteria, followed by preparation of specific recommendations based on
35、the evaluation and performing actions identified by the review. Typical milestones and their relation to space project phases are defined in ISO 14300-1, and in Clause 6 of this International Standard. 4.2 Process model 4.2.1 Function hierarchy The project review process is presented in the framewor
36、k of a model using the syntax and semantics in IEEE Std. 1320.1-1998. This model identifies the necessary functions to be performed in terms of the function name and purpose, its inputs, outputs, mechanisms and controls. For reference, the essential features of the modelling syntax and semantics use
37、d in this International Standard are summarized in Annex A. This International Standard uses the diagrammatic portion of IEEE Std. 1320.1-1998 as a framework and does not claim full compliance with IEEE Std. 1320.1-1998. For clarity in communicating the relationships between the review functions, th
38、e model is construed as a three-level hierarchy of functions, as shown in Figure 1. This hierarchy can be used for guidance in planning reviews; but for a conforming application of this International Standard, use of this hierarchy to represent the process is not required. In a conforming applicatio
39、n, the twelve functions at the third level of the hierarchy of Figure 1 shall be implemented. Detailed requirements and guidance for these functions are given in Clause 5.

40、 20 02:56:21 GMT+00:00 2007, Uncontrolled Copy, (c) BSI 4 4.2.2 Co-ordination of functions A function may be performed concurrently with any other function and in any order that is appropriate, so long as the necessary inputs, controls and mechanisms are in place for the performance of the function.
41、 The performance of a function may be interrupted if this is appropriate, for example, because of resource conflicts. In many cases the inputs, outputs and controls can consist of many increments of data or other material that are available at distributed times. Similarly, not all personnel particip
42、ating in implementing a function are needed for the production of some specific increment of output. In these cases, outputs may be produced incrementally, rather than held until the total output has been completed. 4.3 Review context The review context, corresponding to level 0 of Figure 1, is show
43、n in Figure 2. The central box represents the function performed by the complete review process. The function of the review process, as stated in 4.1, is to evaluate project status relative to a specified project milestone. For the purposes of the diagram, this is abbreviated to “Evaluate project st
44、atus”. The incoming arrows at the top and bottom, and on the left of the function box represent necessary preconditions for the review to be performed. Specifically, a) the review process is controlled by the project review policy and the milestone criteria; b) the input to the review process is the
45、 total set of project data files; and c) the mechanism for performing the review process includes 1) available independent experts, 2) available project experts, and 3) the project decision authority. Requirements for these preconditions are given in 4.4. The concrete result of the review is an agre
46、ed report of conclusions, recommendations and action items, and an approved plan for resolving any remaining problems. These outputs are shown on the right of the function box in Figure 2. Requirements for these outputs are given in 5.5. Every model is an abstraction and includes only factors that a
47、re important from a certain viewpoint. The review process model used in this International Standard uses the viewpoint of project management.
