  2. 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.

  8. SMART Force Examples

  9. Balancing Act

  10. 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

  11. Conclusion • Our experiences with components fits with Services • It depends... • There may be multiple correct answers • However... • Decision should be: • Transparent • Communicable
