To increase probability of your asks being successfully completed, you need to say the following four things:
(1) I want
(3) to do X
(4) by Y date.
Simple enough, but regularly we forget about this simple rule and for the sake of “politeness” we use vague terminology along the lines of: “It would be great if someone took care of our social media”.
Yes, there will be situations when this vague approach works, but if you are after consistency in your workflow and you delegate a lot – stick to the “four elements” principle.
NB: depending on the cultural differences, you may need to pad the message out a bit and start with small talk or spread the message across several paragraphs, but make sure all four elements are present otherwise the chances of successful completion are squashed from the get-go.
