The following is an industry experience on using well established concepts, domain-specific language and code generation, to automate the engineering process of sub-system interactions. A domain-specific language was used to improve the communication efficiency among several teams of engineers. A code generator transforms the models formed for communicating into executables that process data. While, the savings in terms of man-effort and schedule-time were high, the single point of failure is end-user adoption. Adoption failure was attributed to two factors: One, the distance between the end-user and the realized benefit. Two, the amount the end-user had to change (become proficient in skills outside of their discipline). In our experience, the lack of an appropriate editor was the dominate cause to both factors in adoption failure.
