The worst part of DD is when your report clearly states some massive red flags and that the deal should not happen, and the money guys go forward anyway. Why? Because then 6-12 months later they’re angry that what you said was true and you get tasked with fixing it. I recently had to quit a company because they money guys kept wanting me to do dumber and dumber things because they refused to acknowledge the fundamental failure of their plan and were determined to do it their way. I quit, and then everything I was holding up fell down as they tore out the supports to do it their way. Within months the board finally fired the CEO and COO, asked me back, and I declined. It was a purely ego driven failure.
