Bob Carpenter has a good rant on grammar.
The test I would urge everyone to use before buying software or even software services is to ask to see their documentation.
Give it to one of your technical experts and ask them to turn to any page and start reading.
If at any point your expert asks what was meant, thank the vendor for their time and show them the door.
It will save you time and expense in the long run to use only software with good documentation. (It would be nice to have software that doesn’t crash often too but I would not ask for the impossible.)
