Validate and Adjust
Most of this article focuses on acquiring, modeling, and using data, but this was all done to see real results. So, we must also include measuring the results.
Our model got us started, but it shouldn’t be stagnant. As real projects are completed, new data should be fed into the model.
How much did the solar panel project actually cost? How long did it take? What is the measured improvement in electricity cost and carbon emissions (was there one)?
This is new data that informs our model and helps us to adjust it to align expectations with reality. This (hopefully) increases your confidence in the solutions you are putting in place and that your model is providing valid predictions, which is vital when reporting to customers, other agencies, and shareholders.
