ISO 2015 All rights reserved v PD ISO/TS 22317:2015ISO/TS 22317:2015(E) Introduction This Technical Specification provides detailed guidance for establishing, implementing, and maintaining a business impact analysis (BIA) process consistent with the requirements in ISO 22301.

21、This Technical Specification is applicable to the performance of any BIA process, whether part of a business continuity management system (BCMS) or business continuity programme (BC programme). Hereinafter, BC programme means either BCMS or BC programme. Figure 1 notes the relationship of the BIA pr

22、ocess to the BC programme as a whole. The organization should complete a cycle of the BIA process before business continuity strategies are selected. Figure 1 Elements of business continuity management (Source: ISO 22313) The BIA process analyses the consequences of a disruptive incident on the orga

23、nization. The outcome is a statement and justification of business continuity requirements. The BIA process consists of a number of individual BIAs, each focusing of a sub-set of the BC programme scope. The BIA process prioritizes products and services, and continues with prioritizing processes and

24、activities that together cover the entire scope of the BC programme. After a period of time determined by the organization, individual BIAs are repeated to ensure that the BC requirements remain current. NOTE In this Technical Specification, business continuity requirements has the same meaning as c

25、ontinuity and recovery priorities, objectives, and targets (ISO 22301:2012, 8.2.2). The purposes of this Technical Specification are the following: provide a basis for understanding, developing, implementing, reviewing, maintaining, and continually improving an effective BIA process within an organi

26、zation; provide guidance for planning, conducting, and reporting on a BIA; assist the organization with conducting a BIA in a consistent manner that reflects good practices; enable proper coordination between the BIA process and the overarching BC programme. vi ISO 2015 All rights reserved PD ISO/TS

27、 22317:2015ISO/TS 22317:2015(E) The outcomes of the BIA process include the following: endorsement or modification of the organizations BC programme scope; identification of legal, regulatory, and contractual requirements (obligations) and their effect on business continuity requirements; evaluation

28、 of impacts on the organization over time, which serves as the justification for business continuity requirements (time and capability); identification and confirmation of product/service delivery requirements following a disruptive incident, which then sets the prioritized timeframes for activities

29、 and resources; identification and establishment of the relationships between products/services, processes, activities, and resources; determination of the resources needed to perform prioritized activities (e.g. facilities; people; equipment; information, communication and technology assets; suppli

30、es; and financing); understanding of the dependencies on other activities, supply chains, partners, and other interested parties; determination of how up to date the information needs to be. NOTE For purposes of this Technical Specification, supply chains produce supplies of goods, works, and servic

31、es, which are referred to as supplies throughout the remainder of this document. The following diagram displays the BIA process, together with prerequisites and its relationship to strategy identification. The clauses referenced in the diagram are subsections of this Technical Specification. Figure

33、ain a formal and documented business impact analysis (BIA) process. This Technical Specification does not prescribe a uniform process for performing a BIA, but will assist an organization to design a BIA process that is appropriate to its needs. This Technical Specification is applicable to all orga

34、nizations regardless of type, size, and nature, whether in the private, public, or not-for-profit sectors. The guidance can be adapted to the needs, objectives, resources, and constraints of the organization. It is intended for use by those responsible for the BIA process. 2 Normative references The

NOTE All terms and definitions contained in ISO 22300 are available on the ISO Online Browsing Platform: www.iso.org/obp. 4 Prerequisites 4.1 General As noted in

37、 the Introduction, this Technical Specification is consistent with ISO 22301, but it could be used to develop, implement, review, maintain, and continually improve a BIA process addressing other standards or regulatory requirements. Whether part of a BCMS or a BC programme, the organization should c

38、onsider a number of prerequisites before starting the BIA process. Clause 4 summarizes these prerequisites, many of which are from ISO 22301. The organization should take a number of steps within the BC programme before beginning the BIA process, which include the following: define the context and s

39、cope (4.2); define and communicate roles and responsibilities (4.3); obtain leadership commitment (4.4); allocate adequate resources (4.5). NOTE For additional information, see Annex A for a mapping of each step to ISO 22301. TECHNICAL SPECIFICATION ISO/TS 22317:2015(E) ISO 2015 All rights reserved

40、1 PD ISO/TS 22317:2015ISO/TS 22317:2015(E) 4.2 BC programme context and scope 4.2.1 BC programme context Successful BIA process outcomes are dependent on the organization understanding the following: the external environment in which it operates so that it can achieve its purpose by delivering its p

41、roducts and services to customers; the internal operating environment, inclusive of processes, activities, and resources, as well as the potential impact caused by disrupting the delivery of products and services; and laws and regulations mandating the BIA process and how it is performed. NOTE In or

42、ganizations operating within a non-commercial environment, the customer can be the public or an overseeing authority, such as government. 4.2.2 Scope of the BC programme Before determining the BIA process scope, the organization should define and document the scope of the BC programme in terms of it

43、s products and services. The BIA process may assist the organization to review the scope of the BC programme. Following the definition of the BC programme scope, the organization can determine the BIA process scope which may be conducted as a single BIA to cover the whole scope of the BC programme;

44、or undertaken in a number of phases that, over time, covers the whole scope of the BC programme. NOTE If the organization chooses to undertake the BIA process in phases, it should first determine the prioritization of all products and services (see 5.2) and then continue with the remaining individua

45、l BIAs. 4.3 BC programme roles 4.3.1 BC programme roles and responsibilities Prior to performing the BIA process, top management should ensure that the responsibilities and authorities for relevant roles are assigned and communicated within the organization. 4.3.2 BIA pr oc ess-specific ro l e s and

46、 co m p e t e n c i e s Following the assignment of BC programme roles, top management should provide resources necessary to perform the BIA process, which may include appointing the following roles: the person sponsoring the BIA process; BIA steering committee; the person leading the BIA process; t

47、he person managing the BIA project (project manager); process owners; activity managers. The person sponsoring the BIA process should be an executive representing top management, be well respected within the organization by other members of top management, have an organization-wide perspective, 2 IS

The BIA steering committee should represent top management, provide ongoing advice and guidance on the conduct of the BIA p

49、rocess, agree on the methods and outcomes, make decisions regarding business continuity requirements, and assist the person leading the BIA process and project manager in determining the competences required for BIA process-specific roles and responsibilities and the awareness, knowledge, understanding, skills, and experience needed to fulfil them. The person leading the BIA process should have an understanding of the organization, in partic
