Unit Testing: Applicable only if modifications will be made to accommodate customer-specific needs<\/li>\n\n\n\n
Performance Testing: Vendor should provide a SLA (Service Level Agreement) for product performance\n

If the system will handle heavy load\/peak processing (e.g., Class Registration), the ND customer group should consider performing their own load testing for the applicable business function(s)<\/li>\n<\/ul>\n<\/li>\n\n\n\n
Security Testing: Typically involves the assigned ND Developer or Technical Lead (and possibly Identity Access Management or Information Security for consultation) in conjunction with the Vendor<\/li>\n<\/ul>\n\n\n\n
