Defining and analysing the problem is the first step of solving any problem. This is an important step, as changing the problem definition will change the solution to the problem. Hence the need to have a Design Pattern concept while defining and understanding any problem. This ensures more efficient and effective way for representing the key aspect of the successfully tested solution to the problem in the arbiter context. Like the Analysis phase, the Designing phase also plays a crucial role in the Software Development Life Cycle (SDLC) model. The Design approach clearly defines overall architecture of the product, along with its relationship, communication and data flow representation with the internal, external, dependent modules as well as third party modules. A Design Pattern encapsulates the intention behind a design by identifying different objects, their distribution of responsibility, and collaboration between them. This provides a method of reducing the complexity of the system by defining and naming the abstraction. Design framework provides a systematic way to be used at each possible stage of SDLC with some new notation and reuse from Unified Modelling Language (UML).
