I would say...
- Look for the root cause to the problems you notice. If you have something that is going wrong in your area (missing Unload Goal Times for Log, missing REDcard goals for GE, missing TWT goals in HL etc), always look for the underlying reason this is an issue. Many ETLs think, "Oh, we are missing Unload Goal Times, so I am going to spend the next month pumping the team up".... but this isn't addressing the problem. There is likely something wrong with the line (amount of people, roles not defined on the line, bad custom blocking) that is causing the problem, and those need to be fixed. Don't be a band-aid, be the permanent solution.
- If you are telling someone to do something, always follow it with "because"... this makes it sound like you are teaching the team, not demanding them.
- Remember to think long-term over short-term. Don't make decisions on what is going to make YOUR life easier, make decisions on what is going to make the next ETL's life easier after you leave. That is how you know you are making the right decisions.
