Like many companies, yours probably has a zero-accident objective, and maybe also a zero-defect objective. But you can also aim
for zero-breakdown. To implement this, you will need to adopt a more proactive approach when it comes to maintenance either
with a time-based or age-based plan, or even through condition monitoring.
Basic preventative maintenance usually takes the form of a time-based maintenance schedule. It includes activities such as:
Here is an example of a time-based preventative maintenance plan for pumps:

There are a series of questions you need to ask to establish which kind of preventative maintenance approach best suits your factory.
Here is a flowchart to sum up different maintenance approaches with the questions:

For example, if it's not technically and economically feasible that condition monitoring will detect a gradual loss of the function, then a time-based maintenance approach might be more feasible.
