ABSTRACT The interaction between the classes or within the classes shows the complexity of the design. For one smaller problem, there may be more than one software design but who will be the best; depends on the complexity level of software design. Therefore, coupling and cohesion which shows the interlinking of classes and strength of classes; control the complexity of the design. The best software object oriented design is based upon the low coupling and high cohesion level. In the present work, a real case study of Life Insurance policy for handicapped person is demonstrated through the UML Class Diagram; coupling and cohesion levels are measured and results are demonstrated in the form of tables.
