If you're talking about your colleagues and using the word 'should', stop.
Accept that they aren't doing whatever you think 'should' be done.
And think how you can help. Or better still, ask them.
You could start with "I’m curious what's stopping you doing...?"
- Do you want to do it? (Are there any ethical issues?)
- Are you able to do it? (Do you have the skills and experience?)
- Is there something else that's getting in the way? (A broken process or lack of prioritisation perhaps?)
Now you can talk about what will help turn the ‘should’ into action.
Talk is cheaper than assumptions.
