The authors also identify a number of publicly available data sets with the potential to assist in benchmarking performance in strategic, tactical, and operational forecasting. Even though different teams and systems may deal with the different forecasting problems, the problems are connected. Interactions between operational, tactical, and strategic forecasting are complex and difficult to understand, and most organizations erroneously assume independence between these problems, ignoring the interactions. Such a classification can help decision makers understand what resources to draw upon when facing a particular problem and may lead to more scientific discourse about the relevant data sets for benchmarking forecasting performance.
