1.9  A Standard and Code of Practice for IT Service Management

The British Standards Institute have published 'Specification for IT Service Management' (BS15000) and 'A Code of Practice for IT Service Management' (PD0005), both of which are based on the principles of ITIL; the context diagram from BS15000 is reproduced below. The diagram is not a process model but simply a pictorial description. It can be viewed in the same way as Figure 1.1, i.e. the main principles (of Service Management in this instance) are placed in a coherent context, providing guidance that enables the reader to make links between related process elements.

Figure 1.3 - BS15000 Service Management processes

Considering PD0005 in the context of Figure 1.3, it is obvious that the new IT Infrastructure Library models can be seen as an expansion of the BSI model, taking IT Service Management forward. The process elements are nearly the same, the principle of Change and Configuration Management as a linchpin is the same, the difference relates to the level of detail. Both BSI and OGC promote similar, if not identical, principles of best practice for IT Service Management.
