    Dear Willard,

    The straightforward Waterfall Model process for system development was
    devised by W. W. Royce in 1970 [1]. There are more realistic/less
    simplistic models for system development, such as the Spiral Model by
    Boehm [2]; a high-level overview can be obtained from [3].
          [There are many other models, such as the German 'V Model' or, more
    recently, eXtreme Programming (XP), but they are perhaps not worth
    mentioning in a 'Computing for the Humanities' curriculum.]

    And what happens when the layered cake is replaced in your introduction by a cascading waterfall? Notwithstanding your not yet having the benefit of consultations with students, I would be curious about your speculations.
