SAF and RFLP

[napdynamite]

A general question for someone wanting to use SAF. I've been modeling systems using RFLP approach which is what SAF is pretty much all about.

Question: RFLP is a multilevel approach with levels such as context level, system level, subsystem level and component level. Follows the Vee cycle downhill. Each level has RFLP and decomposed further down each subsequent level. Is SAF still applicable here? For example, in the component level how would one model the operational domain viewpoints? or is it something to be dealt smartly with?

This mapping aligns SAF viewpoints with the RFLP approach across multiple levels, ensuring that each viewpoint is appropriately placed within the systems engineering process.

Hello Anas, thanks for contributing to SAF. I am going to move this thread to the discussions area.
