This has enabled enormous increases in product sophistication and the ability to manage high rates of product change over time. Similarly, disciplined production and management of "Enterprise definition" (i. e. the set of models identified in the Framework for Enterprise Architecture) should provide for an accumulation of a body of Enterprise knowledge to facilitate enormous increases in Enterprise sophistication and accommodation of high rates of Enterprise change over time.

The analytical approach employed by both BSP and BISC is "top down". The implications of the words "top down" are multiple and varied, and all apply to these analysis. For instance: Top down implies scope - that is, looking at the business as a whole as opposed to looking at pieces or subparts of it. Top down implies level of detail that is, looking at the highest level of summarization and then decomposing hierarchically to lower levels of detail as required. Top down implies perspective - that is, the perspective of the highest levels of management as opposed to the operational levels of management.

Underlying the BSP and BICS analysis are the data management problems that result from systems design approaches that optimize the management of technology at the expense of managing the data.
