Do you 'model early, model often' ?

I was speaking with a services partner today, who coined the phrase 'model early, model often'. We were discussing performance assurance from early in the lifecycle, working with loosely defined designs, and incomplete data.

We already know that modelling is a great way of predicting an outcome, but we can't take the results of a model seriously unless we're always updating them with the most current information. Calibration, and recalibration will ensure that your models retain their value throughout any extent of time - and as designs and business processes become developed, capturing their changing profile within your model-universe will keep your future vision accurate and always useful
