1. Continual Improvement:
We should focus on continual improvement in terms of processes than in terms of product.
To improve a process it is necessary to understand it completely and to identify external factors
causing special causes of variation.
Role of SPC in process improvement:
SPC lets improvements be applied in a controlled environment, measuring results scientifically ,
and with assurance.
Example:
Breakfast cereal packing line.
Predictability of process:
It is difficult to predict about a process that how is it going to respond or work .
To perform efficiently your process should be predictable.
Role of SPC in predictability of process:
SPC ensures you about your capability because now processes are under control, repeatable,
and predictable.
Example:
Company have a contract to manufacture 300 units but it cannot complete it because of its
unpredictable process.
