The SIR framework is concerned with developing structured designs. A system designed within the SIR framework could be implemented in any programming language, but the transition will be smoothest if the target programming language supports the design constructs directly. If the target language does not offer direct support, then in order to achieve the correct semantics it may be necessary to introduce extra classes and objects that are not present in the SIR design for a particular system, and in some cases there may be no appropriate implementation solution.
