Implementors are the technical experts who implement the system defined in a RIDDL specification. These people are most often Software, QA, and DevOps Engineers. Of course, throughout implementation they will be supported by the Author(s), Domain Experts, and other related staff. Implementors use the output from the RIDDL tools to aid in their comprehension and coding of a solution that corresponds to the RIDDL system specification or model.
It is incumbent on the author and implementation team members to keep the RIDDL sources up to date and accurate as the system evolves. The implementation team members must notify the author of changes to the model that the technical implementation necessitates.
Implementors should be experts in Reactive Architectures. In addition, software engineers, and to a certain extent, other implementors need to be well versed in the implementation tech stack. The creators of the RIDDL language have found that Scala and Akka deployed into a cloud environment provide the best tooling and support for implementing a reactive system. It is not surprising then, that some concepts and constructs found in RIDDL have strong parallels to these tools. It must be noted, however, that reactive systems can be implemented using a variety of languages, frameworks, environments, products and tools. Cloud native offerings can be used with great effect. The critical point is, throughout implementation, reactive principles must be forefront in mind as implementation choices are made.
It must also be stated at this point that even though it may conflict with reactive principles, the business has final say in major implementation choices. It is incumbent on the implementation team to advise decision makers on the risks and challenges that are posed by making choices that conflict with reactive principles. Factors like time, cost, user experience, business rules, availability of technical talent, strategic partners, and so on are all extremely important and may conflict with the choices of the implementation team and sound reactive architecture.
