"Analyze and mitigate the bullwhip effect where demand variability amplifies upstream in supply chains. Use this skill when the user needs to diagnose order variability amplification, quantify the bullwhip ratio, or implement dampening strategies — even if they say 'why are our orders so volatile', 'supply chain variability', or 'demand amplification problem'.".

Recommends continuous subcutaneous insulin infusion (CSII) over multiple daily injections (MDI) for adults with type 1 diabetes who have achieved their A1C goal but experience severe hypoglycemia or high glucose variability, provided the patient and caregivers are willing and able to use the device. Consider CSII when clinicians hear 'A1C is at goal but patient has severe lows or glucose swings' or think 'pump for hypoglycemia-prone controlled T1DM'.
