Does your company use predictive modeling?

Does your company have multiple predictive modelers to discuss questions and concerns as a team?

If so, what techniques do you use common in your industry?

Are multiple linear regression, time series, experimental design, statistics inference served as good foundation to learn predictive modeling?

If there's only one predictive modeler in your company, how do your actuaries make sure his or her work is completely correct?

Thanks.
