Truth Is Time-Dependent

Every project generates a truth. The problem is that truth tends to expire, quickly. Whether it’s the schedule, the budget or even the scope, what was accurate last week rarely remains the same today. It's a moving target, and the exact opposite of what we all like to call a “shared truth.” 

Instead, they're working from competing memories of an old one.

So that begs the question: How do you keep truth current when dozens of stakeholders are all changing it at once?
