What the differences between corrective action, preventive action & defect repair.
In the project management world, you'll hear terms like corrective action, preventative action, and defect correction all the time.
Corrective Action.
Preventive Action.
Preventive action is
an activity that ensure the future performance of the project work is aligned
with the project management plan. The differences between corrective action and
preventive action is corrective actions are taken based on happened / actual
results while preventive actions are taken for future anticipated risks.
Consider that one of the senior project team members may retire in two months, and if he does, there will be no one to hand over his duty, and hiring a new engineer to hand over his task will take time, which will affect the project schedule. As you can see, this is a risk that has not occurred, but there must be a response strategy in place to meet the impact of this risk if it occurs.
Defect Repair.
Defect repair is an
activity to modify a nonconforming product or product component. Once a product
or deliverables are completed, it must be checked that whatever it is meets the
requirements. If there are problems with the product or deliverables, this
problem must be fixed by the project team before handing it over to the customer.
Consider the camera of the smart phone built in the project, which does not automatically activate the flash at night. If this was a need specified at the start, it must be corrected, which is known as defect repair.
Approved change
request in a project can be corrective action, preventive action, or defect
repair because change requests are submitted if there is a new requirement in
the project to correct variances, prevent the impact of any kind of risk and
fixing defects.
Very good definitions of these concepts, they helped me a lot in a job that I have to do and involves part of this topic.
