Assistants to exchange are otherwise called business administrations. Administration area incorporates business firms occupied with keeping money, correspondence, transport, protection and warehousing. Business cannot be even imagined in the absence of these services. All these services collectively constitute the Service Sector.
Business service management or business studies and management (BSM) is an approach used to manage business IT services. BSM promotes a customer-centric and business-focused approach to service management, aligning business objectives with IT or ICT from strategy through to operations.
A BSM approach is most commonly applied in an Information and communications technology (ICT) environment, positioned above IT Service Management (ITSM) (which is often exercised according to guidance such as the Information Technology Infrastructure Library – ITIL). BSM is distinctive in ensuring that business and customer objectives provide an input which is considered when defining the IT Service Management approach and the business services to be offered by the IT Service Provider (whether an internal IT department or an external service provider).
According to the 2011 edition of ITIL, business service management is “the management of business services delivered to business customers. Business service management is performed by business units.”
ITIL, according to the ITIL books themselves, is “a set of best-practice publications for IT service management”. ITIL does not, therefore, give guidance on Business Service Management or Service Management outside of the IT domain.
