The triad constraints, (also known as the “Iron Triangle”)
- SCOPE
- COST
- SCHEDULE
Traditional vs. Agile
1) WATERFALL: We define the scope and plan cost and time. Since cost and time are our variables, we need to control their variance towards the baseline through EVM* or buffer (if using a critical chain project management approach)
2) AGILE: We define cost and time (a.k.a Time Bucket Approach) and plan the scope. Since scope is our variable, we need to control its variance towards the baseline (using tools like the a “ Functionality Backlog”)
*EVM = Earned Value Management
