    2ere can these system tools be found? Within the system itself or the research and analysis first.?

    An important phase in the development of the new system is the documentation of the information flow within the existing system. In this step, all the data in the system is recorded from when it is received, through manipulation in the system, until the final information is produced. In each phase it is important to note who is providing the system with the data, performing the manipulation and receiving the information that is produced.

    Documentation of information and management the flow information is important for the life of the project not only in the analysis phase. Sure there are specific systems and documents to use during this phase but it is important to identify that this action/tool whilst in the intial planning phase establishing controls mechanism and executed from this point.

    Documenting the flow of the data will help the analyst to design a system that would be appropriate to the needs of all parties involved.

Information flow within the company showing how the various employees interact with each other in the system. An important phase in the development of the new system is the documentation of the information flow within the existing system. In this step, all the data in the system is recorded from when it is received, through manipulation in the system, until the final information is produced. In each phase it is important to note who is providing the system with the data, performing the manipulation and receiving the information that is produced. There are a number of tools that are used to represent these features - Data flow Diagrams (DFDs), Context Diagram and Entity Relationship diagrams. The reason why this stage is so important, is that it allows the analyst to develop a complete understanding of the way in which the various parties interact with each other in the system, and thus design a system that will be responsive to the needs of all of the parties involved. It also has the benefit of identifying the areas in which the company has direct control, and those for which it must rely on outside sources. Obviously, when designing a new system, there is no point in changing areas which the company has no control over, such as specifying data must be received in a particular way, when the person who is supplying that data is under no pressure or obligation to change the way in which they supply the data.

    At this stage the information is documented to enable the smooth flow of information within the new system.
