Once implemented, ISO 20000 sets requirements in order to continually improve your SMS (Service Management System). And, this is a never-ending story. But, to start improvements (or, sometimes, corrections), you need to start somewhere. The internal audit is one of the sources you can use. ISO 19011:2011 is the international standard that sets guidelines for auditing management systems. It’s an excellent source of information needed for the internal audit. But, there are some requirements in the ISO 20000 standard itself that need to be fulfilled in order to get certified (see the article The brain of an ISO auditor – What to expect at a certification audit to learn more about the auditor’s approach). Consequently, there are also side effects of an internal audit.
ISO 20000, like most of the standards, is based on the PDCA cycle (Plan-Do-Check-Act or Deming cycle). Basically, the Plan phase is where you define your SMS and plan all your activities and processes to be implemented. The Do phase is where you really implement what you planned. And then, in the Check phase, you have to make sure that your SMS is implemented and performing as planned. This is where your internal audit takes place.
Before you started implementation, the SMS scope, policy, and plan were set. Your management wants to be sure that the SMS is performing as agreed (which is described in the above-mentioned documents). There are two options for this task. One is measurement and the other one is the internal audit. Let’s focus on the internal audit. Basically, the internal audit should confirm that your SMS and the services it supports are fulfilling service requirements and are performing as agreed. Of course, the internal audit should also confirm that ISO 20000-1 requirements are fulfilled.
The internal audit is a mandatory requirement of the standard. Therefore, the company must ensure that all requirements related to the internal audit are fulfilled. For that, there are two persons who are crucial for the internal audit to succeed.
First of all, you need someone responsible for the internal audit, as such. This person will be responsible for:
Another important person is the internal auditor. The standard doesn’t set many requirements on auditors’ characteristics – only objectivity and impartiality, i.e., auditors should not audit their own work. That means that the auditor can’t be someone who implemented the SMS or is involved in the maintenance of it. But, from my experience, the auditor should be:
These are just some of the auditor’s characteristics. All social skill characteristics of the auditor are a huge advantage as well, e.g., ability to present (his opinion/view or findings) or be a good listener… etc. But, the question is – where to find one? Well, if you are a smaller IT organization, it would be hard to satisfy the standard’s requirement on auditor’s impartiality. This means that you will have to look for an auditor outside the organization. Someone from quality management will be good enough to check whether the standard’s requirements are fulfilled. Maybe there is an internal audit department inside the organization (which is hardly to be the case in smaller organizations). One possibility is to hire someone external. That will ensure impartiality, but it will also bring someone with experience in ISO 20000 and ITSM.
Besides that the internal audit is mandatory, it’s an even better idea to gain as many benefits as possible. I have done internal audits and experienced that the auditee (organization that is audited) tries to gain as much as possible during the audit process. They saw the opportunity to hear someone else’s experience and view on the same thing they do internally.
Here are a few benefits of the internal audit:
Once you perform the internal audit – you know where you are. Although some people (i.e., auditees) find the internal audit as “checking whether they perform their job correctly” – it shouldn’t be like that. The internal audit and the result it produces are prerequisites to take (improvement) action. Improvement actions should not be seen as something that serves the organization to satisfy their customers better. There are many opportunities inside the organization to improve. You just have to know which ones. The internal audit can give that answer.
