Introduction Highlight and discuss the considerations required to reuse, buy or build components and services in order to deliver the required solution to the business. We ve identified three areas we think are worthy of discussion; an Evaluation Framework, Forces and a Balancing Act.

Balancing Act Business Technical Requirements Maintenance Cost Support Delivery Time Maturity Business Drivers Complexity
Fit With Services Evaluation Framework Reuse Probably less interesting, because services as highly likely to be reused Buy Integration, the same priority Customisation, should be less of a priority Build Skill, the same priority Core , the same priority Additional dimension to the Evaluation Framework Service Level Agreement Forces and Balancing Act Apply to services in the same way they do with components
