The concept of approval refers to the act of formally agreeing with, authorizing, or accepting something as satisfactory, good, or acceptable. It involves granting permission, conveying a favourable opinion, or confirming that something meets specific criteria before it can proceed or be finalized. Approval serves to maintain quality, ensure compliance, and control project progress in various contexts, from personal decisions to complex business processes. At KBS we worked on this and achieved thru system development.
