To your last question, I think you grow in that skill by figuring out how understand the goals / interests of partner orgs, and then reframe both of your interests to the common goal of the overall company. You don't say "here's what I want", you say "here's what our company and our business needs - how can we work together to meet that critical need?". On your question on the net 90 (I know that's an obscure but critical reference), I took multiple paths. Going to net 90 (or as some companies have, to net 120!) is fundamentally unfair - it is IMHO against the J&J credo, and attempting to improve J&J cash flow on the backs of suppliers. I worked hard to build trust and common interests with supplier, and this undercut that goal because it was presented to them as "we're big, you're little, so take it or leave it". So, I took several tacks: - In some cases, i was able to convince finance that we had a contract or other reason to allow shorter payment terms. My finance partners were fine with it as long as I could justify it to their management. - In other cases, I was able to renew an existing Master Services Agreement or the like to preserve their previous payment terms. - I was usually purchasing services rather than materials, so in many cases I was able to work with the supplier to let them raise their prices to mitigate the impact. And, what do you know - that was a win-win, because Finance didn't care if we paid more - they just cared that they could say we were paying at net90. I'm probably outing myself on some of these things, but part of my role was to find ways around the BS to get the job done. I would have gotten in trouble if I had admitted to doing some of these things, but I would have gotten MORE in trouble by losing suppliers and not getting the job done. Anyway, thanks for raising the question and letting me weigh in!
