Critical success factors Lean must be part of long term Trust strategy This is not a FAD!!! Dedicated service improvement resources accelerate change Staff must be empowered to make improvements Focus on the system, the flow that creates value, then apply the tools Board commitment and clinical leadership is essential Get results quickly deploy a series of rapid improvement events
What is Lean? Lean is the process of identifying the least wasteful way to provide value (better, safer care, with no unnecessary delays at lower cost) to our customers. Value must always be determined by the customer We spend 75-95% of our time doing things that increase our costs and create no value for the customer
Lean focuses on dramatically improving flow in the value stream and eliminating waste SPECIFY VALUE UNDERSTAND DEMAND FLOW PULL PERFECTION IMPROVED EFFICIENCY AND SPEED

Implementation of Lean: benefits Hereford Hospitals NHS Trust Improved quality and safety Fewer mistakes, accidents and errors, resulting in better care Improved service experience Improved delivery/ timeliness Better work gets done sooner (meets targets) Improved throughput (more income) The same people, using the same equipment, find they are capable of achieving more Accelerated momentum Stable working environment with clear, standardised procedures creates foundations for constant improvement Value for money lower costs, less waste Improved staff morale
Lean Sigma complementary not competing Lean goals include Empowered staff Improve flow Doing work on time Identify problems (defects and backlog) before it s too late Learn by doing Eliminate waste Right first time, every time Match resources to meet demand NHS Institute for Innovation and Improvement

Convert non value adding time to value adding time to improve productivity Number of nurses per Trust = 800 Length of a shift = 480 minutes Typically, 50 % of time is value adding = 240 mins per shift 50 % of time is non value adding = 240 min per shift (searching for things, unnecessary movement, chasing results, redoing things) Now, if we can convert 10% of non value adding time to value adding time = 24mins extra value adding time This is the equivalent to 38 extra nurses (23 mins *800 nurses = 18400 extra value adding minutes)

Waste is Anything other than the minimum amount of equipment, materials, space, and worker s time which are essential to add value to the product or service. A symptom, not a cause, of a problem. We need to find and correct causes of waste.

Three Keys to Leadership Go See. Senior managers must spend time in the workplace. Ask Why. Use the Why? technique daily. Show Respect. Respect your people. Learn the dirty details by getting involved and doing. Focus on the work and staff. Learn and revisit Standard Work. Use Value Stream Maps to expose the WASTE Think of yourself not as a firefighter, but as a teacher/coach and process owner/designer.

Learning Points Lean is a very big topic not fully covered today Key points See system from patient s view point Separate out the different value streams Optimise your activity to improve the flow through the whole system for the patients (mapping) Batching is usually bad for flow Reduce waste wherever you see it Create a culture of continuous improvement
