12. Flow Question Framework Create Can we produce what the customer wants when it is needed? Can we deliver what the customer wants and prepare for the next according to real demand? Maintain Organise Measure Can we keep the flow going so that it does not stop? Can we maintain a predictable flow rate in order to achieve planned performance? Are we organised to support flow through the whole process chain? Can we deal with variation? Can we react quickly to resolve problems and recover? Do we measure to promote actions which support flow? Do we know what it needed at each point in the process chain to achieve the overall goal? Are we developing the right resources and skills? VISION REWARD CUSTOMER NEEDS SATISFACTION DESIGN DELIVER

Editor's Notes
Runner – a product or service having sufficient volume and familiarity to justify dedicated resources and standard processes Repeater – a product or service at intermediate volume and regularity which is handled by reconfiguring existing resources and processes Stranger – a product or service which is required intermittently and at low volume but still profitable or necessary to satisfy customers which is disruptive to resources and processes
Six Rights (Peter Hines): Right product, place, time, quantity, quality, cost Principle 4 is important to service management – in happens naturally or should in simultaneous production and consumption 99% of a product becomes waste within 6 weeks of sale
25 themes – and more? What classification – input, process, output, policy, etc
A more rigorous approach
WORMPIT (variant on Ohno) : Waiting, Over-production, Rework, Motion, Processing, Inventory, Transport Other wastes: making wrong product, untapped human potential, excessive information/communication, time, systems, natural resources, knowledge Six Sigma techniques should be used: Measles chart Fishbone Lead and takt time calculations Box and whisker Frequency plots Confidence intervals Correlation Regression and trends Failure mode and effect analysis (FMEA)
Waste: anything other than the minimum amount of equipment, material, parts, space and human resource which are absolutely essential to add value to the product [or service]
More Peter Senge: The easy way out usually leans back in Cause and effect are not closely related in time and space Small changes can produce big results - but the areas of highest leverage are often the least obvious You can have your cake and eat it – but not all at once Dividing an elephant in half does not produce two small elephants There is no blame
