When you are implementing your DAM, you are introducing a large change into your organization. Companies have a limited capacity for change, and if you are leading the charge, in order to succeed, you should be mindful of several things.
Do a few things well, rather than many things badly.
We in IT all have limited resources to complete projects. Even given large amounts of money, staff for development and training, outside/vendor resources for fixes and adaptations, the people inside, your customers, that are using a new DAM or related system still have to do their daily jobs, go on summer break, and sleep.
They are dealing at the same time with other changes, like OS and MS Office upgrades, laptops filled with spilled coffee, customers of their own who want things yesterday, and filling out expense reports. So, try not to shove too much change through your company at any given time, or you can impede its core mission, or even break it.
