We describe a number of strategies for a future service oriented market place. We describe the SLA’s role within the service
framework, and how it enables customers to make value judgements regarding the quality of a service. We also discuss the complexity
of too much choice from both the customer and provider points of view, and advocate a “discrete offer” approach. We discuss
the “cost of negotiation” and argue that it must be carefully balanced with the cost, value and risk of the offering being
negotiated for. We add to the negotiation analysis with presentation and discussion of some results showing a simulated Grid
market place and show that it is possible for service providers to deny themselves work through attempting to offer a high
quality guaranteed service.
