As a company launches more and more products and their portfolio becomes larger and larger, it can become very cumbersome to manage such a large portfolio. Several of their products may be in the decline phase of the product life cycle, yet they remain on the market. It is very important that companies regularly evaluate their portfolio to see if it makes sense to obsolete products that are just stagnant or declining in sales. The reason this is so important is because it costs the company a lot of money to support a product in the field, so if it is not making the company any money they are just losing money on that product. From my experience, for a long time my company did not really ever obsolete any of its products, but we have now started to realize that we are wasting money maintaining such a huge portfolio when we really only have several power products, so we now have begun evaluating some of our legacy products to determine if it makes sense to obsolete them. Does anyone else have experience with PLCM and obsoleting products?
