The triangle relationship between product Design <-> Product <-> Engineering seems so hard to get right and maintain. You need experts that can straddle these lines and make sure each branch is on the same page and their concerns are appropriatly attended to, regarding the needs of a business. I hate blaming others, it's hard to enact productive solutions when battling against people you need to work with, I like blaming lack of processes. How do we as engineers guide the most efficient solutions for the business problems, and in turn make our product development effective, nimble, less wasteful. I for one have really focused on developing process around design and engineering communications. It seems harder to make an impact between dev and product or design and product, often there is an imbalance of power and that branch is the executive and can order some really dumb and wasteful decisions if they don't have proper consult with and respect towards the other branches.
