Given our understanding of the current system’s scope, problems, and opportunities, we can now establish system improvement objectives (Whitten & Bentley, 2007).

In addition to identifying objectives, any known constraints must also be identified. Constraints place limitations or delimitations on achieving objectives. Deadlines, budgets, and required technologies are examples of constraints (Whitten & Bentley, 2007).

It is an academic/professional discipline bridging the business field and the well-defined computer science field (Whitten & Bentley, 2007). This process contains a theoretical foundation with more common legacy to include people, procedures, data, software, and hardware that is used to gather and analyze digital information.

Clerical and service workers perform most of the day-to-day transaction processing in the average business (Whitten & Bentley, 2007). The...
