6. References
References given by the provider may not be related to the provider.
Ensure the provider can give you solid references. Request contact details to allow you to follow up these references. Find out how the provider offers these customers, and how highly the customer values the provider. Ask if you can see the systems developed in their working environment, for example. Ask about all aspects of performance, not necessarily just those you may be interested in. Times may change, and in any case, it is good to make sure the provider has fully encompassing resources and experience.
If the provider is unwilling or unable to provide contact details, see if you can get them yourself (for example from the Software Producer) and contact them yourself. You may find out that the customer was serviced by another provider altogether.
