Notes on State Changes

  1. Review State is just indicated by the attribute value and can be used by any viewer to filter out the requirements in Review State.
  2. When an Owner is assigned to a requirement, the state automatically changes to Assigned.
    1. If the user tries to change the state to Assigned, he/she should be given an error asking to assign a user in order to change state.

Ownership

The ownership will fall into three categories

  • Creator, who owns the requirement in the Unplanned Table.
  • Assignee, who is allocated the requirement by the project Manager.
  • Product Owner,  who has rights over the entire set of requirements in the project.

Permissions

The following set of permissions will be significant for the Requirement Approval Process:

  • Edit Unplanned Requirements.
  • Edit All Planned Requirements.
  • Edit Allocated Planned Requirements.
  • Manage and Approve Planned Requirements.

Implementation Constraints

  1. The workflow should not impact the usability of present system.
  2. This means that there should be no complex configuration screens, no additional popup's. everything should look identical to a user who does not wish to use this feature.
  3. The state changes should be enforced through values assigned to attributes.
