Traditional Approach vs. Agile Approach

The agile approach has the following advantages over the traditional approach:

The triple constraint

Agile flips the triple constraint of scope, schedule and cost upside-down. In a traditional approach, the project scope is fixed and the schedule and cost change to serve this scope. Conversely, in agile we have the scope adjusting based on a fixed schedule and cost. This gives us a lot of flexibility as we do not expend time (the schedule) and resources (the cost) to achieve some distant end-goal (the scope) but rather change this end-goal based on the time and resources available to the team. The total value delivered (the scope) will be optimized in this way.
