Agile Business Analysis Practice

A solution that exists in some manner is best described as an implemented solution. This term refers to a tangible outcome that has been put into practice and is actively functioning within a system or environment. It signifies that the solution is not just theoretical or under consideration, but is actually operational and contributing to addressing a specific problem or need.

In the context of Agile and business analysis, understanding implemented solutions is crucial as it aligns with the iterative nature of Agile practices. Solutions are often developed and refined through successive iterations, and the focus on delivered functionality helps teams to assess real-world effectiveness.

The other terms, while relevant in certain contexts, do not convey the same level of maturity or functionality. For instance, a prototype solution suggests an early version or model that may not yet be fully operational. Conceptual solutions pertain to ideas or plans that have not been instantiated, and temporary solutions indicate a stopgap measure that may not be fully developed or sustainable in the long term. Thus, "implemented solution" is the most appropriate term for a solution that is currently in use.
