Dotsourcing + script and modules are 2 different things. Modules are great to collect/group functions and cmdlets that you would use in a script. If you have functions that you want to use interactively(you call a function in a console), then module can be a great fit.

If you have one big script that you run to .. let's say "migrate a file share", or a single script that you call regulary using Task Scheduler, then dot-sourcing easier.

It depends on what you need. Summary:

• If you just use the the functions/scripts in THIS situation(script/job) = use dot source.
• If you use common functions/script that are used in other scripts too OR you want to call some of the functions interactively etc. = use module.
