I've only been with the organization a little over a year, but I've started to gain a reputation for being willing to take on the projects nobody wants and being able to turn them around in a time much quicker than what they would anticipate (underpromise, overdeliver). 

This is largely because the previous company I worked for, I'd have to turn around large projects in 2-6 weeks where projects of smaller size at my current role I have 10-12 months to turn around. I just never adjusted my pace when I left.

In any event, I got assigned as a secondary on a project with a coworker in a different region (we report to different people, but ultimately all within the same overreaching sub-organization) and she was supposed to be the lead on it and we were given 4 months to complete this project. She's been with the organization about 8 years. 

Basically the project was 200 items that we had to figure out the status of, get approval to update a couple of pieces of information on, and then submit for an update. So we split the list in half straight down the middle.

Then she immediately went on vacation and then just kind of vanished due to illness for a couple of weeks, leaving me on my own.

So I went to work on it and I completed my half of the list in a couple of weeks and since she was MIA, I started working on her part of the list too. Once she finally got back, I had gotten through about 70% of the list and we divided it in half again.

Fast forward a couple of weeks, I've completed the half that was given to me and her status update list hasn't really moved, so I've been asking her if there is anything she needs me to do do so she can complete it since I know she is really busy. She always keeps saying no. 

I send out reports every week with the link to the status sheet (the bosses requested this link be included) and then quick overview reports of where we are on the grand scheme of the project. I purposely don't put which percentage of who did what on the overview reports because I don't think it's relevant to presenting to a director. However, you can look at the status update sheet and see who completed what.

Apparently her boss decided to look at the status update sheet and saw that I had completed something like 80% of the overall list and didn't have any In Progress anymore and her part of the list was still largely set to In Progress and only had a handful of complete items and she got a stern talking to about not taking lead on it.

She was a little touchy with me this morning because of the talking to she got because apparently I made her look bad to her boss. I apologized and told her that I don't really care who does what part of the project, if she does 5% or 100%. I only care that the project gets completed on time and we are on track to completing our part 3 weeks ahead of the other teams that are working on this in their respective areas. I still don't think she's all that happy with me about it. 

Am I the asshole here?
