First story is not exclusive to private equity. Sales and even business owners have no idea how long things take. We once had a project that would take about a year, sales signed the contract to be done in like 1 month. The saving grace was the client delayed their start date, giving us the time we needed. Another one: guy buys an old building with plans to tear it down and build a new one. Tells the news “we’ll break ground next month”. Two years later they break ground.
