The best practice and RAND approaches to problem solving have been widely debated in the academic world. Best practice is a process where existing solutions and ideas are used as a basis to form a new solution or process. In this case, a successful approach is applied to a new problem. On the other hand, RAND is a process where completely new and innovative solutions are developed from scratch, with no basis in existing practice. Both approaches have their pros and cons, but it depends on the situation and the type of problem. Best practice can be a time-saver, as it requires little research or significant effort. It can also be the ideal approach if the problem is similar to an already solved one. On the other hand, RAND is suitable if the solution to a problem is completely unknown, or if the existing solutions have not been successful.
RAND is more time-consuming, as it requires a great deal of creativity and research. In addition, a RAND solution is not proven to be successful at the onset, and could lead to significant investments if it fails.Ultimately, both best practice and RAND can be effective depending on the situation. However, it is important to determine which approach would be the most suitable before starting any project. Only then can an appropriate and successful solution be reached.
