I hope you are hearing that infamous line from Cool Hand Luke with Strother Martin's sweaty, smarmy, southern drawl. It needs to be heard that way to get the full dramatic effect.
This may be a bigger problem organizationally than any shortcomings you may have in DAM and the state of your respective physical and digital assets. You may not even fully recognize the true scope and impact of this failure.
One of the key steps in getting to the (previously mentioned) DAMsta's paradise is to effectively communicate...and then of course, effectively listen. Business needs to foster a free and open exchange of information and ideas that helps get to the core of problems and ultimately make things better. It's all about teamwork.
While this seems simple it can be frustratingly difficult. The conflict in styles between the left-brained techies and the right-brained creatives can exacerbate the problem. Add this to the daily challenges of supporting business goals, disconnected silos, company politics, personalities, etc....and it can get well-intentioned, but ugly.
Poor communication can undermine the perception of value. You need to market your efforts within the organization (not shamelessly...but don't be shy). For example, if you are dealing with fire drills to fix critical problems preventing the company from meeting critical deadlines...just doing it isn't enough.
If a tree falls in the woods and no one is around to hear it does it make a sound? I dunno...but I do know that if you drop everything to feverishly work to fix a critical problem and no one knows about it...then no matter how hard you worked on it people will always be complaining about the lack of support. Bad communication or no communication can be the enemy of productivity and create the perception of bad support EVEN when that is far from the truth.
So what do you do? Proactive communication, simple proactive steps will go a long way toward disarming negativity...knowledge is power and in this case knowledge is comfort.
A quick update to confirm acknowledgment of the problem, followed by an action plan and timeline and then by a status update will go long way. These don't need to be novels; a sentence or phrase will in most cases be plenty and they can be standardized or auto generated. The value is that it tells the person or group that is stuck in deadline hell that someone is on it and there is a supportive partner now vested in the solution and helping to assure you meet deadline.
Let's not forget, we are all on the same team. Can we tawk?
