PILLAR 2: MANUFACTURER PROCESS RELIABILITY

Process Reliability

Process Reliability is about understanding the manufacturing process, the
inputs, manufacturing activities, the outputs and all of the influences on the
process. It is able achieving a stable process and eliminating variation and
waste. It is also critical to understand whether the losses are due to poor
process control or poor reliability (see Figure 8 below to understand where
defects come from):

Figure 8 : Sources of Loss

Continuous Improvement Techniques are used to improve the above and
drive out waste and variation and include:

▪ TPM (Autonomous Maintenance)

▪ RCA

▪ Kaizen

It is about understanding the losses and using a systematic way to
reduce/eliminate the losses.

Process reliability is a

method for identifying

problems, which have

significant cost reduction

opportunities for

improvements. It started

with the question: “Do I

have a reliability problem

or a production problem?”
