Sandy Kemsley: “…agility often depends on the design decisions such as the split between process and decision logic – what do you model in as a decision, and what do you model as a process. Unsurprisingly, many DM practitioners don’t think first about processes, but suggest that you first focus on determining and modeling your business decisions, then build processes to gather the information and execute the steps required to make those decisions. Within those decisions, however, they often use rule flows, which are really processes that link together individual rules/decisions into larger decisions; this starts to muddy the waters.” Link
