2 by Gerrit Muller Buskerud University College Abstract Most s fit in a larger family of s. The members of such a 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 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. customer Customer Business drivers information order support Distribution This article or presentation is written as part of the Gaudí project.

3 Typical Examples of Generic Developments Platform Common s Standard design Framework Family ure Generic aspects, functions, or features Reuse s (in project environment) 3 Gerrit Muller GDnames

4 Claimed Advantages of Generic Developments Reduced time to market Reduced cost per function Improved quality Improved reliability Improved predictability Easier diversity management Increases uniformity Employees only have to understand one base system Larger purchasing power Means to consolidate knowledge Increase added value Enables parallel developments of multiple s Free feature propagation building on shared s build every function only once maturing realization modularity economy of scale not reinventing existing functionality -to- or project-to-project less learning 4 Gerrit Muller GDclaims

5 Experiences with reuse, from counterive to effective bad longer time to market high investments lots of maintenance poor quality poor reliability diversity is opposed lot of know how required predictable too late dependability knowledge dilution lack of market focus interference but integration required good reduced time to market reduced investment reduced (shared) maintenance cost improved quality improved reliability easier diversity management understanding of one base system improved predictability larger purchasing power means to consolidate knowledge increase added value enables parallel developments free feature propagation 5 Gerrit Muller SWRexperiences

6 Successful examples of reuse homogeneous domain hardware dominated cath lab MRI television waferstepper car airplane shaver television limited scope audio codec compression library streaming library 6 Gerrit Muller SWRsuccessful

7 Limits of successful reuse struggle with integration/convergence with other domains how to innovate? TV: digital networks and media cath lab: US imaging, MRI poor/slow response on paradigm shifts TV: LCD screens cath lab: image based acquisition control software maintenance, configurations, integration, release MRI: integration and test wafersteppers: number of configurations 7 Gerrit Muller SWRlimits
