Hi!
I have chosen Scenarios A, B and C.
For Scenario A, it DOES make sense to use a template. This is because you will be mass sending thank you letters to your purchasers.
For Scenario B, it DOESN’T make sense to use a template. This is because the letter you are writing will probably just be a one-off letter, and you won’t need to write another one.
For Scenario C, it DOESN’T make sense to use a template. As mentioned above, the report will probably just be a one-off report, so it doesn’t make sense to use a template.
I hope that this helps you out!
