Analyze organizational processes to identify information systems requirements

For this discussion, you will practice analyzing processes to identify functional requirements for a system to improve a process.

This week’s discussion topic focuses on system requirements that need to be clearly written so that the people who are developing the system or evaluating a system for use can discern whether the requirements are met or not.

The requirement statement:

  • Is a complete sentence, with a subject (system) and predicate (intended result, action or condition)
  • Identifies only one requirement; does not include the words “and,” “also,” “with,” and “or.”
  • For Functional Requirements, states what tasks the system will support or perform
  • For Non-Functional Requirements, states how the system will perform.
  • Includes a measure or metric that can be used to determine whether the requirement is met (time or quantity), where appropriate
  • Is stated in positive terms and uses “shall” (not “may” or “should”); “the system shall xxxx” not “the system shall not xxx”
  • Avoids the use of terms that cannot be defined and measured, such as “approximately,” “robust,” “user friendly,” etc.
  • Is achievable; avoids terms such as “100% uptime,” or “no failures”

Explain your assessment as to why the information is or is not correct and/or complete, providing correct information to enhance the discussion.

1. Drawing from your own experience, select a process used at your place of work or in your interaction with an organization that you would like to see improved. Explain why you picked that process.

2. Imagine that a system is to be implemented (or an existing system improved) to make that process better and identify five (5) requirements that the system would need to satisfy. Each requirement is one sentence in length and addresses one thing the system must do. Here we are interested in “functional requirements” – the activities the system must perform to support the identified process. We are not including “non-functional requirements” that include how the system would perform. Use the information

above to create your requirements statements.
