Networking on the Job

The new challenge for me now is how to network my duties and responsibilities in relation with the overall management of a manufacturing plant...although I was used to just managing or handling a single department...HR ...but now my new job has to be able to look out for IT, ACCTG, MKTG, HR, PURCHASING...i need to evolve in the way I have to cope with these various duties...and the bussword for me would be networking...I need to network with the rest of the departments such as TQD, PRODUCTION, and PRDT...thats the challenge that I have to deal with...I don't think that its a difficult one...its more of a heightened awareness of what the right hand and left hand is doing...the need for the right information for the right people at the right time...so much for that stuff...work is starting to get the best of me...I guess that's normal for somebody who is new in the organization and needs to make a mark on others...how one could help and be integrated as a part of "them"...
