One approach I recall taking as the in-house developer for a company's warehouse management system was to designate the warehouse I was in to be the "experimental" warehouse: new features (or new systems entirely!) would be developed/configured in coordination with that warehouse's team, and they were generally comfortable with the idea that they would get those new features first (with the risks that entails). Once my local site had used the new feature/system for a few weeks without major incident, it would then get rolled out to the other sites.
