Final answer:
An advantage of the "best of breed" approach is that it facilitates competency development, allowing businesses to excel in specific core areas by choosing the best systems available for each function, and aligning with the strategy that specialization tends to lead to greater success.
Step-by-step explanation:
One of the advantages of a "best of breed" approach over single vendor options is that competency development is facilitated. This method allows a business to focus on acquiring the finest systems in each separate area of their operations, leading to excellence in specific core areas. By selecting the best system available for each function, businesses can avoid the need to compromise on functionality and performance, as they might have to with a single vendor that offers an all-in-one solution but is not equally strong in every area.
Moreover, this strategy aligns with the concept that businesses focusing on a narrow range of products or services - their core competencies - tend to be more successful because they can offer a higher level of expertise and quality in those areas. A best of breed approach encourages this level of specialization by enabling companies to select the best possible systems and thus, enhance their core competencies.
