We use PDCA (plan - do - check - act) when approaching changes to practices along with KISS (Keep It Simple & Sustainable). In the PDCA, we discuss the practice under review, what the afters (desired results) will be, and how we want to approach this (Plan). We then test out the practice in a small form with a few employees or on a small batch run (do). We review the practice and how it worked, asking questions like is there anything to modify to make it work (check). If there's a problem, we work to resolve the issues which arose and test again PDCA - if not, we have that practice/process replace the old (act). Throughout it all we work to ensure the process is simple, editing out unnecessary complications and/or requirements which have no value add and we check to see if the practice is sustainable over time (eg does the new practice cause issues with other processes? Will this practice create increased paperwork or time which doesn't add value to the process and/or work?).
