Life sciences companies need to be agile in an often-changing market, and forecasting plays a crucial role in being able to do this. The increasing focus on the use of machine learning (ML) and artificial intelligence (AI) can make parts of forecasters’ jobs easier, but there is room for improvement in these and other areas. A recent IQVIA webinar discussed trends in commercial forecasting based on the company’s second annual survey, which was conducted earlier this year.

“This is a very exciting time to be in forecasting,” declared David Wolter, a vice president in IQVIA’s commercial consulting group. And while forecasting is critical to making business decisions, multiple challenges exist within the process.
