1. A method of evaluation and improvement for a process comprising one or more process operations, said method comprising the following steps:
development of a process map for said process; estimation of value-adding and non-value adding process time attributes: cycle time, total time and lead time; estimation of quantity of parts or service per unit of time by dividing total operation time over total cycle time; making an assessment of meeting a customer's demand in quantity of parts or service; revision of an entire process in case of not meeting customer demand in quantity per unit of time, in order to meet customer demand; if meeting customer demand in quantity, deployment of a risk matrix for subgroups Quantity, Quality and Delivery, in order to take into account risks for Quantity, Quality and Delivery; definition of individual risks for each process operation; estimation of risk values for operations, subgroups Quantity, Quality and Delivery and total risk as a sum of risks of said subgroups; adjustment of expected quantity of parts or service by an estimated total risk value, to obtain an adjusted quantity; making an assessment of meeting an estimated total risk to acceptable value; if said adjusted quantity does not meet customer demand, or if estimated risk of quality does not have an acceptable value, finding a first subgroup with a biggest risk contribution among Quantity, Quality and Delivery, by development of a first Pareto diagram among such subgroups; Selection of a first process operation with a biggest risk sub-contribution within said first subgroup, by development of a second Pareto diagram within said first subgroup; Selection of an improvement action for the first process operation, capable to reduce said biggest risk sub-contribution, followed by implementation of said improvement action; Repeating one or more of previous steps until Quantity meets customer demand and total risk reaches an acceptable level, or until further improvement actions are not cost effective. |
