As an ERP expert, it is quite clear to me that even the best systems will fail miserably if they don't possess talent. Don't even bother to select and implement an ERP system if you don't have the "right" people on the bus. Start with executive support and continue on down through every position – everything is a team effort.
Lately, we've been called into several clients with ERP challenges that directly impact business growth and success. Do you desire profitable growth? If so, add ERP into your strategic discussions. Would you delegate a decision that could literally "make or break" your customer service, profit margins (or lack thereof) and ability to grow? I think not!
We cannot tell you how many clients call thinking they need a new system to support their business when it isn't true! Certainly there is a time to upgrade to a new system - when you've outgrown your old one (often-times QuickBooks with add-on's like Fishbowl), your old system is highly customized and unsustainable or you are in the midst of a merger or acquisition.
