The purpose of this step is to have sufficient input to operate and test the model. Solution of the model: After selecting the appropriate data input, the next step is to find a solution.

If the model is not behaving properly, then updating and modification is considered at this stage. Validation of the model: A model must be applicable for a longer time and can be updated from time to time taking into consideration the past, present and future aspects of the problem.

The implementation of the solution involves so many behavioural issues and the implementing authority is responsible for resolving these issues. The gap between one who provides a solution and one who wishes to use it should be eliminated. To achieve this, O. A properly implemented solution obtained through O.
