Our Plain English service management standard is designed to be used as
a Checklist. That's because we’ve used a task oriented approach to translate
the original ISO IEC 20000-1 standard into Plain English. This means that our
Plain English product (our Title 15) consists entirely of tasks or actions.
So if you want to implement the ISO IEC 20000-1 standard, all you have
to do is carry out the tasks that we have listed.

As you study these tasks you may realize that you’ve already performed
some of them. In order to keep track of what you’ve already done and what
you still need to do to meet the ISO IEC 20000-1 2011 requirements, we’ve
provided a way of recording this information. For each task, two responses
are possible: TODO or DONE. If you haven’t done the task, select TODO.
If you’ve already done the task, select DONE.

To see what our checklist looks like, please have a look at the following free
sample PDF: ISO IEC 20000-1 2011 Checklist (Part 7 of our Title 15 product).
