MMUs work best when three fundamentals come together.

First, *clear anchoring: each MMU should be mapped to defined PHC catchments with a fixed micro-itinerary—predictable village days, school and workplace halts, and referral slots pre-booked at the PHC’s. This predictability builds community trust, improves attendance, and helps PHCs plan staff time for referral closures and chronic-care reviews.

Second, *standardized service packages: a small, disciplined list—vitals, basic labs for NCDs, ANC/PNC checks, immunization support, essential medicines, and immediate referrals—prevents mission creep and keeps visits efficient.
