Demand forecasting
2001 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

The telecommunications company Ericsson has outsourced a large part of the production. Material purchase and the production are based on forecasts that Ericsson makes. These have a great importance, since false forecasts can either cause costly inventories or delayed customer deliveries. Ericsson’s forecasts have exceeded the actual market demand for the last year, which has forced Ericsson to compensate their suppliers for excess and obsolete material. In order to reduce these costs and to secure future deliveries it has been decided to improve the forecasting and planning process. The purpose of this Master Thesis is to improve Ericsson’s forecasting and planning process for switching and access products. To restrict the extent of the thesis it was decided to make a case study of only one product, Engine Access Ramp. Further, only the hardware production at the suppliers Solectron and Flextronics in Europe was examined. To fulfil the purpose of this thesis, depth interviews and a broad study of internal material have been accomplished. Two other companies working with forecasting have also been studied. This material together with a literature study has been the base for the recommendations that are the outcome of this work. Even though many problems were identified, the forecasting and planning process is generally performed in an appropriate way. Both the theories and the suppliers support the way Ericsson is working. However, some areas can be improved and it is recommended that Ericsson measures MRF and MRP deviation, rewards the MUs’ forecasting performance, implements a forum for discussions of improvements, only sends trend information for month 7-11, adds revision statuses to the MRP, deletes cabinet types as forecast objects, and stops making the SRP in present form. Through accomplishment of these recommendations several improvements can be achieved. The most important are better in-data, better feedback, and more understanding from the suppliers, which together can lead to a mutual trust between Ericsson and their suppliers.
