Hi all. Ive been in my job for a year. The person who trained me has moved to a different team, so I am the only person in my department doing that job (think project manager type job). Since she left, I have been asked to take on different types of projects (while also managing the ones that she taught me to do), and im struggling a bit with the process. There is another department that do exactly the same job as me, exactly the same tasks, but just for their department. Their job is fully specced out, they have accurate job descriptions, a list of skills they need to get a promotion, training courses that would be useful, the process is fully outlined with workflow diagrams- basically everything i have been asking for for the year ive been here (im on my 4th manager and haven't been given much direction on anything).
A few weeks ago, I took the initiative to spend a day with that other department to learn and get some of the things that ive been needing for a year. It was the most useful day EVER, they were so so helpful and it was just so productive.
After that, I had a 121 with my manager and he joined the call stressed. I told him that I had spent the day with them and I had a load of stuff that I could use as a "starting point" for all of my stuff. He didnt have the positive reaction I was expecting 🤣. He kept asking "why did we go for them for it?". When I explained that it was a new process to me, and they had everything I needed, he just kept having awkward silences that I tried to fill by over explaining.
I want to spend more time with this department to learn what they do and why. They have refined their process over years, so even though im doing it "ok", they would know the best way to do things after so much refinement. They are very willing to share with me.
How do I approach my manager to ask for this when he has already been resistant to me spending one day with them?
