If you were asked to highlight the best of PowerShell for SharePoint to a group with only 15 minutes start to finish which features would you include?
The groups skill level will run the entire spectrum from “never heard of PowerShell” to MS Devs.
For an administrator = Script boring tasks that you have to do often, so you only run the script and they are done.
For the developers = I would say how they can create a script to deploy their solution to avoid any mistakes, and easier install instructions
