Managing The "Six" Triple Constraint

Scope, time and cost were the first 3 original constraints. A change to any one of them affected the other, and this basic principle is what is called the triple constraint. As the project management profession matured 3 more constraints were added: quality, risk and customer satisfaction. These 3 are almost always affected by any change in the original 3. Let’s see how they are represented and how they work.
