Look here: http://schemas.dmtf.org/wbem/cim-html/2.34.0/CIM_ConcreteJob.html
Search for "PercentComplete" property. You may also provide indications user can subscribe to.
This way he doesn't need to poll for status. With asynchronous invocation there are just a few
possible values you can return: "Unspecified Error" (2) or "Method Parameters Checked - Job Started" (4096).
Return the first one if parameters are invalid or the job could not be started, otherwise start the job, make instance of CIM_ConcreteJob, return it as an Out parameter and make 4096 the return value of method.

What optional features you want to implement (like Ordered Dependencies, Software Bundles etc.).
What other functionality you are missing in the profile (verification)?
Whether you are content with synchronous methods? - easy to implement.
And when you choose asynchronous, whether to make indications to notify clients?
How to represent your jobs in separate thread or process?
