The issue with discovering a perfect solution to a problem is that We cannot predict the consequences perfectly before the perfect solution

Explanation:

While finding the perfect solution we consume a lot of time and the perfections comes when the experiment is repeatedly performed again and again. A tiny mistake can lead us to a very different result therefore it is not sure that the solution that we are finding is a proper and perfect solution.

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
