As an ERP implementation expert, I'm used to offering advice on how to make your company's implementation a success. But for a moment, I'd like to talk about failure. Even with all of my experience and expertise, there are ways that my client companies can so thoroughly undermine the implementation process that the only way to dig ourselves out is through more money and time than anyone is willing to spend.
I'm a fan of the NCIS head slap. Problem is, if I really did one, my butt would land in jail and all my money would be taken by a huge lawsuit. So accept this written head slap, folks. Pay Attention! And learn from the failures of projects past.
