October 19, 2014 status: preliminary draft version: 1.2 Product Families and Generic Aspects by Gerrit Muller Buskerud University College e-mail: [email protected] www.gaudisite.nl Abstract Most products fit in a larger family of products. The members of such a product family share a lot of functionality and features. It is attractive to share implementations, designs et cetera between those members to increase the efficiency of the entire company. In practice many difficulties pop up when product developments become coupled, due to the partial developments which are shared. This article discusses the advantages and disadvantages of a family approach based on shared developments and provides some methods to increase the chance on success. $$ logistics support order product information sales production service $$ e Product related processes Va lu k Needs Technical product Documentation Customer-Oriented Process Feand edb feedback ac product roadmap budget, plan people Technology Process people Technology Process Shared Assets Creation Process people Technology Process generics Needs & feedback budget, plan presales material Product Creation Process Needs & feedback October 19, 2014 status: concept version: 2.3 Budgets This article or presentation is written as part of the Gaudí project.
