9、ng verification metrics, and reporting procedures. As audiovisual systems have increased in complexity, the chances of misconfiguration, improper installation, and failure to conform to project requirements increase. Managing expectations and verifying conformance with stated project requirements of

10、 audiovisual (AV) systems is the major goal of this Standard. While many organizations have internal processes and verification procedures, there is an industry-wide need to utilize project documentation along with this Standard to identify elements within an AV system that require measurement and v

11、erification. Use of this Standard supports a comprehensive, systematic, and practical approach to verifying performance of AV systems. This Standard requires that project documentation has been created for the project being verified. Documentation will vary from project to project and the standard d

12、oes not prescribe the nature and extent of the project documentation. Conformance to the Standard is not possible without project documentation. This Standard assumes that a project owners operational specifications have been established in the system/project documentation. This Standard does not pr

13、ovide a “one size fits all” verification pathway, but a means to enable the user of the Standard to develop a project-specific list of system performance verification items based on performance requirements defined in the projects documentation. Being able to assess the performance of the audiovisua

14、l system based on what was defined in the projects documentation should reduce dissatisfaction at the end of the project. Using the Standard, consultants, integrators, manufacturers, technology support staff, owners, third-party commissioning agents, and architects who have system performance verifi

15、cation processes in place can integrate those existing processes into the framework this Standard provides, adding customized items to those already defined in the Standard. Benefits of using this Standard are not limited to but include: Ability to streamline verification tests and reporting; Provid

16、ing a verifiable outcome; Creating a common language between all parties; Aligning outcome and performance expectations at an early stage in the project; Creating reporting that completes the project documentation; and Reducing project risk through early identification of problems, thereby reducing

17、the likelihood of remedial work. This Standard should be used in conjunction with ANSI/INFOCOMM 2M-2010 Standard Guide for Audiovisual Systems Design and Coordination Processes as well as other relevant performance standards. About InfoComm International InfoComm International is the leading non-pro

18、fit association serving the professional AV communications industry worldwide. Founded in 1939, the association offers industry expertise and market research serving press and others seeking information about the industry. Through activities that include trade shows, education, certification, govern

19、ment relations, outreach, and information services, InfoComm promotes the industry and enhances members ability to conduct business successfully and competently.

(ANSI) is the national coordinator of voluntary standards development and the clearinghouse in the United States for information on nationa

21、l and international standards. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially aff

22、ected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered and that a concerted effort be made toward their resolution. The use of an American National Standard is completely voluntary.

23、Its existence does not in any respect preclude anyone, whether he or she has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard.

28、eo Performance Cable Management, Termination, and Labeling Control Performance Electrical Information Technology Operations and Support Physical Environment Physical Installation Serviceability Wireless System and Record Documentation 1.2 Purpose 1.2.1 The purpose of this Standard is to provide a fr

29、amework for the verification and reporting of the performance of an audiovisual system based on the requirements specified in the systems project documentation. The Standard defines 160 potential verification items; a process for determining which items are germane to the project and a way to incorp

30、orate additional items; a process for defining the evaluation metrics for verification; a process for verifying the items; and a process for how and when to report those results. 1.3 Application 1.3.1 This Standard can be utilized by all parties involved in the audiovisual system installation proces

31、s including consultants, integrators, manufacturers, technology support staff, owners, third-party commissioning agents, and architects to verify the performance of audiovisual systems throughout the integration process. 1.3.2 Planning for the use of this Standard should begin with the projects init

32、iation. The framework provided by this Standard should be integrated into the projects project management and/or quality management processes. For organizations that have existing project management and/or quality management programs, the framework provided by this Standard can be integrated into ex

33、isting processes. Conformance to the Standard shall require that all requirements of the Standard are included; this Standard does not provide for partial conformance. ANSI/INFOCOMM 10:2013 2013-12-20 2013 by InfoComm International Page 8 1.3.3 This Standard is aligned with ISO 21500:2012:Guidance o

34、n project management, where the activities of this Standard take place within the Implementing, Controlling, and Closing process groups. The Standard is aligned with ANSI/INFOCOMM 2M-2010, Standard Guide for Audiovisual Design and Coordination Processes, where the activities of the Standard take pla

35、ce within the construction phase. For projects where it is known that this Standard is being implemented at project initiation, it is recommended that users of this Standard begin planning for conformance to the Standard at that time. Figure 1 Illustration of Implementation Phases 1.3.4 This Standar

36、d can be applied to any size (scope and/or value) audiovisual system as long as its project documentation clearly cites (and completes) a project-specific verification list during initiation and then subsequently documents verification through the project phases. 1.4 Exceptions 1.4.1 Specific measur

37、ement metrics This Standard does not provide measurement metrics for any defined reference verification items in Section 9. Metrics (beyond pass/fail) should be determined by following the process in section 6.2 of this Standard. 1.4.2 Measurement methodology This Standard does not prescribe any spe

38、cific methodology for achieving the required metrics. Comparable measurement techniques and methods exist in many cases, and the user of this Standard shall choose a method by using the metrics selection process hierarchy as defined in Section 7 of this Standard once a project-specific reference ver

39、ification item is identified. 1.4.3 This Standard does not include prescription for corrective action. 1.4.4 In addition, this document is not designed as a technical training manual or roadmap for specific actions. It is expected that all parties using this Standard have or will obtain the necessar

40、y training and experience through other means.
