A detailed financial plan was created for the overall long-life strategy. Documentation on all of the planned expenditures and expected sales was presented to senior Philips management for approval prior to launching the program. These documents were then updated from time to time as the plan unfolded. Thus far the numbers on Marathon and Halogena are holding as planned. Consumers are definitely trading up to these premium products in large numbers . DuraMax was only launched in 2001, which is too recent to make a final judgment on its success, but it looks very good so far.
