The role of the Trainer is to train both the Primary and Field Integration Engineers on the use of Chameleon/Iguana and ensure that they have adequate skills to perform their functions. They are responsible for being Chameleon and/or Iguana product experts and for ensuring that best practices are followed by the company with the usage of these tools.

The Trainer is also the vendor's single technical point of contact with iNTERFACEWARE. They are responsible for maintaining good ongoing communication with iNTERFACEWARE to:

• Give feedback on where product improvements could be made to streamline their HL7 operations further.
• Understand the significance of new product features to better streamline their operations.

This role is often performed by the same individual that carries out the Primary Integration Engineer function, however, it does require strong communication skills that the engineer roles do not. It is usually best to keep this role separate from the Primary Integration Engineer role as this is an ongoing operational role, whereas the Primary Integration Engineer role is generally not. This role can, however, be satisfactorily merged with the Quality Assurance Engineer role.
