A few years ago I heard about a Scrum developer that got a $10 million contract to deliver software for a big construction company. The two parties agreed on a twenty-month time frame. But the Scrum company inserted a clause into the contract. If the construction firm wanted to terminate at any time, they could—they’d just have to pay 20 percent of the value of the remaining contract. Basically, if the software worked the way the construction firm wanted, they could stop the Scrum shop from building any more.
