About DOORS

https://www.youtube.com/watch?v=Reff4ELfwrM

  • Similar to a word document.
  • Database under the hood.
  • Tree structure for readability (hierarchy).
  • Columns with properties.
  • Filterable.
  • Keeps track of changes (baselines, etc...).
  • Also similar to an spreadsheet.
  • Ability to generate reports.
  • Links between requirement items (dependences).
  • Architecture can be described using DOORS (product tree).
  • Links between requirement items and architecture items.
    • Consistency checks between arch & req.
  • Validation plans can be described using DOORS.
  • Links between req or arch items and validation items.
    • Consistency checks between arch & req & validation steps.
  • Too expensive.
  • From the software development point of view, is a very simple tool.
  • “Closed and de facto industry standard”.
  • Poor interoperability.
  • Poor workflow support.
  • Poor role support.
  • Poor collaborative work support.
  • Needs specific server & specific clients.
  • Tayloring using specific scripting language.
  • Plugin development out of the scope of the clients.
  • Does not allow offline modification.

An hybrid alternative using Redmine + Git.

  • Redmine has:
    • Database under the hood.
    • Redmine + Git can be put in sync.
    • Strong REST API for total interoperability.
    • Strong team support.
    • Strong workflow support.
    • Based on roles.
    • Strong colaborative work support.
    • Need Specific server.
    • No specific client needed (web).
    • Open source & free.
    • Tayloring using:
      • Strong configuration panel.
      • Standard ruby language via plugin development.
      • Any other language (javascript, python, etc..) through REST API.
  • Git is:
    • Roughly speaking, the leader and best tool for version control.
    • The reference tool and vastly documented.

Redmine is a task management tool. We can transform it to be a requirements management tool.
In combination with Git, the requirements can be uploaded/downloaded to/from the BD from/to the filesystem, keeping track of the changes and allowing baselining.

cosmoSys-Req

  • Is is able to include all the functionalities of DOORS.
  • It can provide the same functionality with greater quality.
  • It is providing more features than DOORS right now.
  • It can be extended and improved easily without needing to learn specific scripting tools.
  • It is more visual.
  • It generates better reports.
  • It generates diagrams, complete or requirement centered.
  • It can also be extended (near future) to arch and validation plans.
  • Focused for public or private entities with small budgets.
  • It can be used in offline mode.
  • It is free.
  • It is open source.
  • It is just the beginning.
  • Little (but growing) support.
