The owner matrix or rights matrix is based on a category and sub-category definition that you can chose freely. You then give it a title / path or URL and description. Further do you assign employees to this matrix entry and you can leave a note with details what the employee in there that can state like secondary approve, additional approve etc..
If you set an entry inactive, the inactive date will auto-fill by default, you always can remove it.
To make sense of this imaging the following file-system example:
You have a departments folder with a sub-folder per department, e.g. IT, Accounting, Marketing – all those departments have managers or directors that actually can approve who will gain access to their department folder.
Now an employee requests access to a certain department folder, you now need to know who can approve this request. You go to the rights or owner matrix and look it up.
What you would see in the data is for example this – depending on how you structure it
Now you chose the entry you need to know about and see who are the owners and whom to contact about the request to approve.
Of course you are not only able to do that with the file-system, you can fill in to those fields what ever you feel fit, in the end you have three fields to divide and categorize and you then can add employees directly with further notes and instructions on what they can decide etc.
