Does the Iron Triangle fit the agile approach

The three main constraints of any project are Scope, Time, and Money. But what will happen when you inverse it? The Iron Triangle approach is a powerful and helpful tool. It helps in explaining the stakeholders on why some things can’t be done. 

A classic Iron Triangle looks something like this:

Typically organisations try to predict how much it will cost for an application to be build based on their knowledge. This approach is called Predictive Approach. We usually try to predict how much it’ll cost and how long it’ll take to finish a project. 

But what if you want to make it more agile? It can be hard to predict the future then. In this case, the Adaptive Approach comes into the picture. Where developers have to approach a project in an adaptive way and just adjust the plan accordingly. 

Let’s inverse the triangle here:

Let’s take a look at some of the differences between these two methods. In the predictive approach, the scope is always fixed and the time and money can vary anytime, and vice versa for the adaptive approach. In the inverse triangle, the time and money is the only thing which is fixed since that’s the only thing we are aware of. 

Read on to know more about the Iron Triangle in Agile Methodology and the major differences between Predictive Approach and Adaptive Approach.
