Check out Tim Minahan's detailed and timely critique of Forrester's findings from their recent supply chain survey. Given his background, Tim "the antidote to the pusher-man" Minahan is particular potent in this short entry. I particular like Tim’s analogy to addiction when it comes to ERP functionality extensions: "Just as an addict often acts irrationally, making decisions that are often against his or her self interest. Many companies continue to act the same way when selecting business software. Supply management executives often know their next ERP investment may be bad for them. They know there are "healthier" (read: more innovative) options available. And they know that with each new investment, they are becoming more beholden to their dealer ... er ERP provider. Yet they continue to buy that next module."
