There’s an old saying that suggests, “Don't try to fix it unless you understand it.” With those words of wisdom, the next milestone of our project is to study and analyze the existing system. There is always an existing business system, regardless of whether it currently uses a computer. The problem analysis phase provides the project team with a more thorough understanding of the problems, opportunities, and/or directives that triggered the project. Indeed, the analyst frequently uncovers new problems and opportunities. The problem analysis phase may answer the questions, “Are the problems worth solving?'' and “Is a new system worth building?''

The purpose of the problem analysis phase is threefold. First and foremost, the project team must gain an appropriate understanding of the business problem domain. Second, we need to answer the question, “Are these problems (opportunities and directives) worth solving?” Finally, we need to determine if the system is worth developing.

The requirements analysis phase answers the question, “What does the user need and want from a new system?” The requirements analysis phase is critical to the success of any new information system! In this milestone, we need to identify what information systems requirements need to be defined from the system users’ perspectives and draw graphical, logical models to document the data requirements for a new and improved system.

Data modeling is a technique for organizing and documenting a system’s data. Data modeling is sometimes called database modeling because a data model is usually implemented as a database. Data is viewed as a resource to be shared by as many processes as possible. As a result, data must be organized in a way that is flexible and adaptable to unanticipated business requirements—and that is the purpose of data modeling.

Process modeling is a technique for organizing and documenting the structure and flow of data through a system’s processes and/or the logic, policies, and procedures to be implemented by a system’s processes. In this milestone, we focus on using and constructing data flow diagrams (DFDs) and decomposition diagrams to perform process modeling. Data flow diagrams are tools that depict the flow of data through a system and the work or processing performed by that system. A decomposition diagram is a DFD planning tool that shows the top-down functional decomposition and structure of a system. During this milestone, you will first construct a context diagram to establish project scope and boundaries. Secondly, you will draw an event decomposition diagram to partition the system into logical subsystems and/or functions. Thirdly, you will draw event diagrams to model individual processes. Finally, you will construct a system data flow diagram that shows the big picture of the system, and a primitive data flow diagram for a single event process.
