If you are already a company, or you are planning on becoming one, then it is a good idea to have a strong quality assurance plan in place. By making intelligent use of the iNTERFACEWARE tools, setting up a good quality assurance plan should not be an expensive undertaking. The msgtransform and msgdiff tools mean that even if you are a small company having a good quality assurance program is quick and easy to set up.
Regression testing becomes very important for your quality assurance by the time you have a few dozen customers using HL7. Fortunately you already have the perfect tool for testing your parsing with the msgtransform tool.
By keeping a decent sample of messages from each of your customers you can easily set up an automated nightly regression test to ensure that each release of your software will parse the HL7 from each flavor in the same way.
