A business analyst (BA) is proposing design options and a number of opportunities are occurring...

 An opportunity is a situation in which it is possible for an organization to perform more effectively or efficiently, or to better meet the needs and desires of its stakeholders1. One type of opportunity is increased efficiency, which means reducing the amount of resources, time, or effort required to produce the same or better results2. In this question, preventing different stakeholders from performing the same function in distinctly different ways can lead to increased efficiency by eliminating duplication, inconsistency, and confusion. References: 1: BABOK Guide v3, Section 3.1 2: Business Efficiency
