Best Practices for SOAP scenarios (synchronous)

Hi Forum,

I have some critical scenarios in XI,

the scenarios are expected to receive messages via a web service call, i mean, i m going to expose the scenarios as web services,

the client (third party) will send SOAP messge to the XI scenarios, these are mostly synchronous calls,

for the above, i have used the SOAP sender channel,....

the scenarios are working, but i need to use them in production system, and need to evaluate the reliability of these type of scenarios,

Can u please provide me best practices/guidelines to-be-followed, for creating such SOAP scenarios,
