I have to test some functionality related to user access rights.
Now a user can be granted the following access rights: View, Add, Edit, Delete, Archive, Reports, Security or combinations of these rights.
I want to be able to construct a matrix where I have userís 1-n listed (in rows) and the access right (in columns).
I want to be able to construct the matrix so that I get full (or nearly full coverage) of all the possible combinations of access rights, using the least number of users?
Can you suggest a method of doing this that is quick and efficient?
A matrix is the best way to "see" what you seek,
Knowing the spreadsheet software you use to create the Matrix, he shortcuts that can be used and giving it a little thought or some planning before you start is your best bet.

You might consider using an orthogonal array (sometimes known as "pair-testing"). This site has a free download that walks through Taguchi's orthogonal approach.
Thanks for the reply. I've downloaded the document and this looks like what I'm after.
I'll let you know how I get on.
One other tool to try named AllPairs:
I haven't used it before (I'm more familiar with Taguchi's approach) but it's free, so might be worth your time.
