Nelson uses Savance's Warehouse Management System. Since our implementation we have noticed a marked improvement in accuracy of both inbound and outbound material handling. As we implement new modules we continue to tweak our processes to take full advantage of the functionality. The integration with Array is exceptional. Information flows both to and from Array seamlessly. The WMS decision is one we can pat ourselves on the back for. 
To OrderSavant,
This is an endorsement of a third party Warehouse Management System that works with Array. Nelson has installed Savance's Warehouse Management System, and I feel it has dramatically improved our operations (Savance is the same people who have developed the Order Savance application that provides a GUI for Array). Their web site is http://www.savance.com/
We have been happy with the WMS. The way we have installed it may be different from the way that others have done it. If you are interested in seeing more about how it works here at Nelson we made some (very) amateur videos to show how it works. You can see those videos here: https://mail.nelson-electric.com/webshare/Warehouse_Management_Processes/
We did not spend much time on the screens because they are better shown via Webex, these are just quick looks at how we pick orders, make manifests for trucks, receive, and putaway.
Savance asked for an endorsement of their WMS product- and I am happy to give it. If you would like to more know I would be happy to talk to you about it. If you want the official pitch from Savance then go to their web site http://www.savance.com/ and arrange a Webex. Several of their products are designed to work with Array - so they will probably give you a quick look at all of them.
I should make clear that Nelson is not the first to use the WMS with Array. Others have paved the way. Also, there are other users of other Savance products within the AUG - you may want to get their experiences as well.
Thank You,
