When analyzing the current state, the business analyst avoids considering only parts of the whole situation to avoid working on certain aspects in isolation from other parts. The business analyst must know how all the parts work and fit together in order to recommend changes that will be effective once implemented.

The existing business architecture typically meets a variety of current business and stakeholder needs and therefore must be carefully considered to ensure the desired future state also caters to those needs in order to prevent a loss of value to the organization and its stakeholders.

To better understand this, let's again consider the example of daily parts delivery in the car dealership scenario:

• The business need for being able to service a customer within a day by having access to all required parts in a timely fashion has been established.
• An infrastructure need was identified and addressed by building warehouses closer to the central metropolitan areas, as well as the enhancement of the actual stock delivery process to and from this warehouse.
• The processes within the dealerships were enhanced in order to do real-time stock receipting and invoice reconciliation in order to streamline this process even further. 

If any of these needs were considered in isolation, the solutions and introduced changes would potentially have been much less effective or caused a loss of value in one or more of those business areas.
