Once the model is agreed, the system is implemented by building a real-world version of the model. The idea of modelling is not new. Almost every engineering discipline builds models to invent, and then to specify, the final system. And like any other engineering model, analytical models are readily understood by the people who are to implement the system. Complete Systems Analysis improves on the original ideas of analysis by modelling all of the system, and using strategies to do it faster.
Analysts find that event-response models give a better partitioning of the system.
Complete Systems Analysis has a clear, effective method for event-response modelling. The use of object langauges means that the systems analysis method must place an equal emphasis on the data, and the processes using that data. Complete Systems Analysis delivers a specification that readily translates to the correct classes. The complexity of today's systems means that the analyst is often overwhelmed by the sheer volume of system information. Using Complete Systems Analysis viewpoints you can filter out unimportant information, and model only the significant aspects of the system.
