I'm currently on a project to POC a product from a bunch of different vendors. These products require integration with tools that my team doesn't manage which means (you guessed it!) I have to talk to and work with people from different teams. We are on fairly strict timelines with these products due to licensing and milestones set by the project team, so I need to get things integrated as soon as possible so that I can get the products working and do my analysis on their performance.
This brings me to an unnamed employee that we'll call "Alex", because that is a gender neutral name. Alex is the contact I was given on a team that manages a software we need these product to monitor for the POC. However, Alex won't answer my emails asking about getting the integration set up. I've sent a follow up email every day for the past 3 days and on the last email I cc'd our project manager and my leader. I'm beyond frustrated at this point, because this isn't this first time Alex has done this. I've had to reach out to this person before for help with their software and they never responded then either. That previous issue was less of a priority and I didn't feel the need to follow up, but now it just seems ridiculous.
Update! Alex finally answered me after the email that cc'd my leader and PM
For those of you who have been in my situation, what did you do? How did you get an unresponsive person (who might be blocking your project) to respond to your emails?
