I suggest you do an imagination exercise: try to imagine a client, the most difficult client you have. Add to this customer the image of "very important" even if it is not, the image of "I need and I do not care how you do" even if it generates costs higher than the value it produces, a customer who has some indicators measurable defined for his activity and to achieve those indicators does not care about others around him.
Any attempt to communicate to improve relations and, consequently, of the services you offer hits a wall called "without me you mean nothing", any proposals for improvement are rejected unless you give them even more. much from you, as if it weren't enough for what you've already given him.
How do you feel working with such a client? Motivated and confident in the bright future some would say, toxic relationship others would say ...
This is how the relationship at the warehouse door between Logistics and Production is seen. That, where pride and self-importance are a priority. In my professional activity I had toxic relations and very good relations with the Production department (I being Logistics) - my conclusion is that the kind of relationship and collaboration between the operational departments of a business does not depend only on people, unfortunately the management mode has a harder word to say in this relationship.
As long as Production understands that resources are limited, that it must fall within certain limits, that a business is defined to generate profit not production, and Logistics understands that Production generates value (even if the end customer pays this value) and that SUPPORT department (as are ALL other departments outside Production), Logistics must HELP Production, things are clear, transparent and easy to understand even at the level of operators.
As a Logistic person I started by describing Production for the first time, but as a Logist I also know the biggest flaw (even if it seems quality sometimes) of Logistics: whatever you do is not the fault of Logistics! and they will prove it to you with numbers and estimates - it's always someone else's fault.
How do we manage to reconcile the self-importance of Production and the lack-of-responsibility-based-on-figures of Logistics?
