An entirely new way to review models
Few kudos are awarded for accurate models - but errors certainly get senior attention.
Welcome to the "downside-only" task of model checking.
When we were in your seat, the only way we could be 100% confident in a model's accuracy was to build one of our own on the side.
That's what Mosaic solves for - cross check an Excel model to our independent system in a few minutes and either (i) confirm its accuracy or (ii) quickly surface and address errors.
The only way to be 100% sure a model is right is to re-run it through an independent system
Quickly and confidently validate model math
Manually checking each cell in Excel is a nightmare alternative. We’ve studied dozens of final round bid models and counted an average of 50,000 populated cells per model.
Even glancing at each cell for 1 second would require a staggering 14 hours of review time (which no one would ever do). So what’s the practical alternative today without Mosaic?
High-level checks of a subset of the model with high probability of an error slipping through.
Running Mosaic is the first thing I do when I receive a new model to review and the last thing I do before sharing with my MD.
If the outputs line up perfectly – or if I understand and accept why they don’t – I have full confidence in my Associate’s model.
Achieving that level of certainty without Mosaic used to take me hours.
The only thing worse than building Excel models is reviewing them...
