Each approach has its own benefits.
Some companies set up a cross-functional audit team to encourage identification and adoption of best practices. Others find it beneficial to spread internal knowledge through internal audits. There are also companies that gain efficiencies by combining different audits, for example ISO 9001 and safety.
Outsourcing internal audits to our experienced, certified auditors brings other benefits. We guarantee to find all substantive issues – which is particularly important prior to the certification audit. Sharing our vast experience and providing improvement suggestions and consulting is another good reason to use our service. And then there are some companies that are simply too small or whose personnel is stretched too thin to train auditors and perform audits in-house.
These are just a few of the benefits of each approach but they may give you an idea on how to decide what's best in your particular situation.
