I am in IT and have a business partner who is at times very difficult to deal with. I work closely with him to set our work priorities going forward and provide updates to our project sponsers as a normal IT project manager would with their business partner.
Today, I received an email from this gentleman that suggested that we should a) only tell the project sponsers what we needed them to do to help us rather than ever sharing anything positive b) get my IT house in order because I wasn't getting all this high priority stuff done and it was making us look bad (when he is the primary driver for our priority setting and we are on schedule to meet current priorities as laid out prior to today) and c) I should stop worrying about "looking good" to my management chain and tell them everything that was wrong so they would get us plenty of help.
Any advice on how to handle this? I have spent the last year or more while working with him specifically doing everything in my power to do what was right for the business even though I was the one looking bad to my management because of it, so this was like a punch in the gut when I read this email.
How do I respond to this in a way that has a chance of actually moving the relationship forward somehow?
Thanks in advance for your help.
