Management system audit requirements may include reference to documents such as policies, objectives, processes, procedures, instructions, quality plans, which can when combined with an audit scope statement, deliver internal audits which can be either wide-ranging or focused on any aspect of the organization or part thereof and which has the potential to address risk performance.

ISO 19011 considers that there is a risk associated with delivering an audit program which addresses all the requirements of the various standard or the management system are covered within a year.

Why does this method of scheduling create a risk?

Essentially audit programs which are fitted into an annual 12-month calendar program rarely take risk into consideration.

When a maintenance program is developed, it includes tasks that satisfy the criteria for both applicability and effectiveness.

The applicability of a task is determined by the characteristics of the component or equipment to be maintained.

The effectiveness is stated in terms of the consequences that the task is designed to prevent. The basics types of tasks that are performed by maintenance personnel are each applicable under a unique set of conditions.

Tasks may be directed at preventing functional failures or preventing a failure event consisting of the sequential occurrence of two or more independent failures which may have consequences that would not be produced by any of the failures occurring separately.

Maintenance Program task types include:

(1) Inspections of an item to find and correct any potential failures;

(2) Rework/remanufacture/overhaul of an item at or before some specified time or age limit;
