I think the value of this thread is spending some time thinking through the evaluation process prior to doing the experiment. Often revelations occur while doing the experiment; things you wished you had thought of before you started.
You end up refining the criteria as you go. That is hard to avoid. That is why experiments mature as you repeat them, incorporating lessons learned from previous iterations.
But we don't do this for a living, so it is useful to try to plan criteria as best as possible before hand. There may not be an opportunity for an iterative improvement process.
And what better way to plan than to tap into the collective knowledge of subject matter experts on this forum, as well as the target audience for the results, also on this forum.
This comes down to: "can do", "should do" and "will do" options.
There are a lot of things that are possible to do. Not all are valuable, but, they can be done. These fall in the "can do" category.
Of all the "can do" options, some will prove to strongly support your objective, and thus, should be done. These are the "should do" options.
Going from should to will is where constraints are applied. Constraints are time, money, available equipment, knowledge, desire and others. This is where you pick the options you are actually going to use.
We are going through this process here. So rather than thinking about this as over complicating, think about it as a constructive discussion and analysis of what can be done, what should be done, and ultimately, what will be done.
Obviously, Bentley will make the decision on what will be done, but this discussion could help.
