Summary

Domain Driven Design (DDD) is about evolving a shared model of the domain letting the domain model drive the design. BDD is about establishing a shared understanding of “done” working from the outside in until you get there. DDD enables the use of BDD effectively creating software and BDD helps structure the conversations for DDD.

  • What is BDD?

    It would be helpful if the presentation's teaser text defined BDD. It defines the well-known DDD acronym, but not BDD??

  • Nothing new

    This presentation defines DDD and BDD and tries to link them. However, if you already know about both these terms then you would have in some way found how both of them can be linked to in order to achieve greater benefit. Would have been great if presentation offered greater insights.

  • Funny how the example scenario violates the definition of BDD (slightly, but still)

    by mgpmul mgpmul,

    The example scenario ends with "...Then I see all the previous treatments" (18:30)
    It is funny to see how quickly Dan North jumps from application behavior to end-user behavior, thus violating the definition of BDD, which is meant to describe the behavior of the application (in interaction with the user though).
    To comply better with BDD, the last line would have been better phrased as: 'Then the application displays all the previous statements.
    Whether 'I see' the treatments cannot be verified. It depends on where the end-user is looking at.
    User behavior is random.
