METHODS OF GATHERING INFORMATION – CDE

In this case, try to collect a series of common requirements that you separated from the group in a faster manner than if an interview with each of them.

To articulate use cases easier for the user, although the use cases have to be distilled later into the more specific, detailed requirements..

  1. This requires a separation of the functions of the system into their logical constituents and the production of a logical model, the processes and the data flows necessary to the implementation of this.
  2. You summarize the two articles and, based on your reading, prepare a list of arguments, why this type of system would be useful in a JAD session.
  3. We will first study the more traditional requirements determination methods and progress to more current methods for the detection of the system requirements.
  4. But there are certain techniques that are commonly used: written materials, interviews, questionnaires, observation, and measurement.
  5. If a migration project is not enough documentation of the current system, reverse engineering will determine what the system has.

The entire process by which current methods are replaced, which is referred to with radical new methods in the rule, as business process reengineering or BPR. This iterative process is continued until the product has the critical mass meets business needs or for an agreed number of iterations.

  4. Some of the options for dealing with these problems include training in team development, group dynamics, conflict management; multiple interviewers work together; and technical assistance such as CASE or GSS.

Through the observation of the user, a process flow, pain points, awkward steps and possibilities can be determined by an analyst for improvements. It is investigated whether a well-managed portfolio of projects is more valuable than the sum of the value of each project. It forms the core of classical analysis, and also contains new and accepted tools such as data flow diagrams. Therefore, the usefulness of a technique is determined by your need and the type of benefits it offers in a particular project.
