22、sibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade
23、 Association.

DIN EN 16602-10-04:2014-12 EN 16602-10-04:2014 (E) 5 Introduction Early identification of potential critical items provides valuable inputs to design engineering for their avoida
26、nce or elimination. Critical-item control provides management with acceptance rationale for those critical items that cannot be eliminated from the critical-item list, and identifies the means by which emanating risks can be controlled. This Standard provides the requirements for the implementation
27、of the critical-item control process as described in ECSS-Q-ST-10. DIN EN 16602-10-04:2014-12 EN 16602-10-04:2014 (E) 6 1 Scope This Standard defines the principles, process, implementation and requirements for critical-items control. Clause 4 is the informative part of this Standard whereas clause
28、5 and Annex A form the normative part. This standard may be tailored for the specific characteristics and constraints of a space project, in accordance with ECSS-S-ST-00.

33、 of the critical-item control process are to prevent the occurrence of failures in or problems with items through: provision of inputs to the risk management programme, identifying technical risks; identification of specific items likely to cause problems (critical items); identification of appropri
34、ate prevention and control measures; monitoring, implementation and verification of the control measures. 4.2 Critical-item control process 4.2.1 Critical items and critical-item control Critical items are potential threats to the performance, quality, dependability and safety of a system that are c
35、ontrolled by a specific action plan in order to mitigate emanating risks and to prevent undesirable consequences. 4.2.2 Interfaces between critical-item control and risk management By their nature critical items have the potential to introduce risks into a project. The potential threats to safety, d
36、ependability, performance and quality can be triggered within risk scenarios, which are dealt with by risk management. While critical items are controlled through the CI control process, the associated risks are managed through the risk management process. The interfaces between the risk management
37、and critical-item control processes include (refer to Figure 4-1): critical item inputs to the risk identification activity, risk classifications used to prioritise critical items, references between risk reduction and critical-item control measures, status of critical-item control implementation.

Results
39、from various PA analyses provide considerable inputs for critical item identification (e.g. RAMS: FMECA results, hazard analysis results; PMP: non-qualified parts materials and processes; EEE: non-qualified parts or new technology; lessons learned from previous programmes). 4.2.4 Interfaces between
40、critical-item control and product engineering Critical-item control requirements affect both the specification of a product and the realisation of the product. Therefore, the inputs and the outputs of the engineering process (e.g. technical specifications, and design documents) are reviewed for the
41、identification and classification of critical items (taking into account the lessons learned from previous programmes). Critical-item control measures can establish constraints on the design and development process and are agreed with engineering. Step 1 Define CI control requirement Step 2 Identify
42、 and classify the critical items Step 3 Decide and act Step 4 Communicate and close-out Critical-item (CI) control process Step 1 Define risk management implementation requirements Step 2 Identify and assess the risks Step 3 Decide and act Risk management process ECSS-M-ST-80 Step 4 Monitor, communi

The lower level activities are integrated into the system level activities. The CIL evolves through
44、out the project life cycle starting with a preliminary CIL at PDR.

The supplier shall classify critical items a
45、ccording to the nature of their criticality. c. The supplier shall establish and maintain the critical-item list (CIL) for the project throughout all the project phases to allow the tracking and monitoring of all the critical items identified, in conformance with Annex A. d. The supplier shall defin
46、e specific control measures for the critical items. e. The supplier shall define evaluation points for assessing the implementation of critical-item control measures. f. At each evaluation point, the supplier shall evaluate the need to retain each item in the critical-item list. g. The supplier shal
47、l report the status of the critical items and of the related control measures as part of the project progress reporting and at milestone reviews. h. The supplier shall reduce the criticality of an item either by design or by procedural means. NOTE A critical item for which the associated risk is con
48、trolled by means of procedures receives particular attention in the further processing of the item. i. The supplier shall list all design, manufacturing, and test documentation related to critical items in the CIL. NOTE Document traceability is maintained by document number and issue. j. The supplie
49、r shall monitor manufacturing, assembly, integration, testing, maintenance and operation involving a critical item for problems that can affect the performance of the item during the operational phase.
