Technical innovations and increasing international stress of competition have lead wordwide operating companies as well as small and medium-sized companies to bring very complex products in a huge number of variants into the market. Product Lifecycle Management (PLM) is an approach to handle this complexity. In this paper a generic process model for a pragmatic evaluation of PLM solutions in a PLM implementation project is presented. Over the past years large companies, especially in aircraft and automotive industries, have made experiences with PLM and especially PLM implementation which can be adapted directly or indirectly by companies of small and medium sizes.
