Data science models that work with predictive analytics have a series of challenges; they proper quantification of business sanity, a need to operate in a low data environments where the number of data points may be less than the number of input variables, the ability to handle nonlinear dynamics, transparency in the model design i.e. not a "black box".
Standard tools and methods in data science and machine learning are unsuitable to produce predictive models and measurements to handle such challenges, as the tend to be data-hungry, prone to overfitting, and unable to express business dynamics. To overcome this we use Bayesian Inference methodology, which allows us to express business knowledge as "priors" and thus reduce the need of data to train a proper model without overfitting.
