Waste: anything that adds cost but no value
WWWWHHW: Who, What, Where, When, How, How much, Why
In the terminology of quality management systems, do not confuse:
- anomaly, defect, dysfunction, failure, nonconformity, reject and waste:
- an anomaly is a deviation from what is expected
- a defect is the non-fulfillment of a requirement related to an intended use
- a dysfunction is a degraded function that can lead to a failure
- a failure is when a function has become unfit
- nonconformity is the non-fulfillment of a requirement in production
- a reject is a nonconforming product that will be destroyed
- waste is when there are added costs but no value
- control and optimize
- to control is to meet the objectives
- to optimize is to search for the best possible results
- customer, external provider and subcontractor
- a customer receives a product
- an external provider provides a service or a product
- a subcontractor provides a product or service on which specific work is done
- effectiveness and efficiency
- effectiveness is the level of achievement of planned results
- efficiency is the ratio between results and resources
- objective and indicator
- an objective is a sought after commitment
- an indicator is the information on the difference between the pre-set objective and the achieved result
- process, procedure, product, activity and task
- a process is how we satisfy the customer using people to achieve the objectives
- a procedure is the description of how we should conform to the rules
- a product is the result of a process
- an activity is a set of tasks
- a task is a sequence of simple operations
Remark: the customer can also be the user, the beneficiary, the trigger, the ordering party, the consumer.
