When you re prototyping a new system, what guideline(s) do you use to mark a stop-and-start-over point?
Typically I write prototypes as part of the architecture/design process, to answer questions that can only be answered by actually working with the code. For example, questions such as:
Usually you can write a prototype fairly quickly to answer such questions. Obviously the code does not have to be production-quality, it just has to go far enough to answer these questions.
Once you run out of open questions, I would scrap the prototype and finish your "design". Then you are ready to begin creating a production version.
When the one I m working on doesn t fit the requirements anymore (functional, usability, or otherwise).
Prototypes are meant to be a dispossable item so I never hesitate when throwing one away.
When you ve de-risked the functionality to a level where you feel ready to write production code.

We re doing mockups/prototyping on a MS Surface device and I wonder if anyone has succeeded in using SketchFlow for this. The problem that I see is that the code generated by the tool uses normal WPF ...
I ve used Douglass Crockford s Object.beget, but augmented it slightly to: Object.spawn = function (o, spec) { var F = function () {}, that = {}, node = {}; F.prototype = o; that = new F(); ...
When you are rapid prototyping for features should you really worry about code quality & optimization?.
I m using selenium in my test suite, but since it s slow to set up, I d like to prototype my xpaths on live pages, rather than waiting for tests to run. Is there a good way to do this? Firebug s $x ...
I am looking for some tool that would help me prototype basic website structure and logistics (or simply user interface). It should be extremely efficient in the matter of time needed to do simple ...
from your experience, which is the most effective approach to implement artificial neural networks prototypes? It is a lot of hype about R (free, but I didn t work with it) or Matlab (not free), ...
I have added a simple .js file to my page that has some pretty mundane common-task sort of functions added to the Object and Array prototypes. Through trial and error, I ve figured out that adding ...
