Which of the following is a disadvantage of User Application Development?

User Application Development refers to the process where end-users create their own applications, typically to meet specific business needs. While this approach has several advantages such as fostering innovation and increasing user engagement, it also comes with some notable disadvantages.

One significant disadvantage is the greater likelihood of reinventing existing functionalities. When users develop their own applications, they may unintentionally create solutions that duplicate capabilities that are already available in existing systems. This can lead to inconsistencies within the organization, as various apps may attempt to solve the same problem independently. Instead of leveraging established solutions, users risk misunderstanding existing systems, which can undermine efficiency and lead to wasted resources.

Additionally, this duplication of functionalities can create challenges regarding maintenance and support. It can lead to a fragmented ecosystem where different versions of similar applications exist, complicating training, user support, and system integration. Overall, the risk of reinventing the wheel makes option C a credible answer, highlighting a key downside of User Application Development.
