Reference that outlines benefits of determinism?

I was recently working on a simulator that uses pseudorandom numbers to introduce variance into the system. The seed was based on the current timestamp (and therefore changed with every run).

After checking in a new command-line flag to allow specification of a fixed RNG seed, a colleague asked me "Why does this matter?"

I didn't know where to start ... the advantages seem obvious:

• Ensures reproducibility between runs
• Reduces noise between A/B experiments
• Eases debugging

Instead of giving a lecture, I'd like to point to some existing article that elaborates on these points. Does anyone know a good article or text?
