“Lean transformation” is the process of moving from the “old” way of thinking to “lean” thinking. The lean process involves focussing on value streams. i.e. The way that information and “materials” flow. In our case the “material” we deliver is health care. This is delivered through face-to-face or telephone consultations; it is also provided by writing letters, certificates, filling in forms, referring for further care and prescribing. Formal feedback from our patient group and our own day-to-day feedback provides insight into what are our patient values. We can start to use this insight to look at our process and consider how we can best provide value to our patients. This involves reorganisation along customer/patient value orientated lines.
