Model This

When I first started modeling, my boss came to me and said “Model this…” and then proceeded to describe an area of the plant that he thought “might benefit from having a model”. Unfortunately there were no specific objectives beyond that.

To me, a new simulationist, that sounded like an ideal project. Nothing to prove… Nothing specific to evaluate… No one waiting on specific results (because none were asked for)… It even sounded like a good opportunity to learn how to model. But it was not.

“Model this” generally results in a useless project. A waste of time. Without clients or clear objectives, I could not know what to model. Without clear objectives, I had little motivation to learn how to model tricky situations; I instead tended to bypass them to work on aspects more fun or interesting. In fact, for the same reason I often did not even recognize modeling challenges, so I never learned to deal with them.

Moreover, when it was all done, what did I have to show for my time? Perhaps a cool-looking animation. It probably did not have many aspects of reality to it. Reality is driven by close interaction with the stakeholders – oops, I did not have any of them. Why should anyone waste his or her time sharing domain knowledge with me, when I was basically just modeling for fun?

And worse, after I “finished” the model, I was overconfident of my modeling skills – after all, I modeled everything I set out to model, right? Of course I was never forced to really verify and validate against the real system, so I never really had any idea how good the model really was.

Avoid “model this”. Always push for clear project objectives. More on that next time.

    This article clearly reiterates the fact that building a model for a project should always start with clear cut objectives. Making a model of any process without knowing who the stakeholder is and what his critical parameters are or what the model is going to exactly achieve in terms verifiable and valid results adds no value to the project. Instead it might turn out to be a ‘cool’ looking animation.
    It is always advisable to start any project by first establishing the objectives clearly.
