Design Solution Options

So far, I believe this has been one of the most difficult chapters to read. The IDS and the IT model seem to make great sense. Both models follow a very structural method but not everything in life follows a straight path. The models leave very little room for error, and we all know that things happen. Things are not always going to flow as planed, on the ISD model, one stage is designed for Formative Evaluation and a sub stage that allows room for revision. Once again, this is well designed but what if the problems occur earlier in the model, why not have a similar stage towards the middle of the design, have a Pre-Formative Evaluation, then later in the project, conduct the final evaluation. On the other hand, the IT consulting framework does not have a testing area, from designing the solution, it jumps to selecting solutions but there is no stage to test the selected solution. What if these selected solutions do not function, what if the program still runs as slow as it did before or even slower; what then. Something I like about the IT framework is that it’s direct and to the point. It guides you step by step in what needs to be done to solve the issues at hand.
