Analisi dei processi aziendali. This thesis has been motivated by the author’s lack of information when having to implement a new demand planning system at a multinational company and having to parameterize all factors affecting demand forecasts. When assigned this task, different factors were identified by the author before the parameterization. However, some of the factors were not identified until the system was already implemented and some parameters had not been considered. Thus, the author wondered if a list of factors to consider when planning demand forecasts was available or had been studied by other researchers. Due to the lack of information in this area, the author decided to conduct a study on this topic.
