  • Uba Oguchi Christian Nigeria This is an important phase in the development of the new system (Project) 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.

  • Maria Rosario Acuña-Hilton United States of America I can see here that this special informative flow is to benefit the Analyst and give him understanding on how all these parties interact with each other in the system and also benefit the company from outside source. What's the point? I see more expenses toward the system and what about privacy laws?

  • José Alejandro Villa Cerda Chile I disagree with: 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. Because the company can cancel the contract if the provider doesnt adjust they processes to the company requirements.
