By shifting to more up-to-date computer hardware, Organization were able to provide more computing power for their operations. To select the right computers, management needed to understand :

3.To known the financial and business rationale for hardware technology investments.

Should processing power and data be distributed to departments and divisions, or should they be concentrated at a single location using a large central computer? Client/server computing facilitates decentralization, but network computers and mainframes support a centralized model. Which is the best for the organization? Each organization will have a different answer based on its own needs. Managers need to make sure that the computing model they select is compatible with organizational goals.
