What to know about the Triple Constraint for the PMP exam!

Happy Tuesday to all of our wonderful students! I know it’s been a few days without a post. So, here I am at it again.

Lately there has been a lot of talk about constraints on my project.  I am always asked are there any constraints with your tasks.

Triple Constraints sometimes called the Iron Triangle was introduced by PMI with the following definition is the balance of the project’s scope, schedule (time) and cost. Triple constraint is used to gauge whether a project’s objectives are being met.

So, what does that mean in English terms?  Change is inevitable, changes do occur on projects and when they do they don’t happen in vacuity. When the scope of your project is changed, your time and cost will be affected.

The same is true when time and cost are changed, something in scope will be affected.  The theory is letting us project managers know we must be cognizant of the triple constraint and to help keep others aware of it.

We should not just accept all changes as valid but we need to evaluate how those changes would affect the elements of our project.

How many times has your organization slashed a budget or removed a task without realizing the consequences on other parts of the project. Organizations must know scope, time and cost are interrelated.  When one changes it will definitely have effect on the other.

Let’s fast forward to PMBOK6, the triple constraint has been expanded to represent not a triangle but a hexagon.  Hexagon has sides that represent quality, risk and customer satisfaction.

Did a light bulb turn on, doesn’t this make sense in our everyday project life.  If something in our scope changes we evaluate how it will affect the quality, customer satisfaction and if there will be any risks associated with that.

PMI is letting us know as project managers we must not assume but evaluate, review, assess any change requests and determine their impacts on other elements of your project.

I hope this post clarified project constraints and now you can answer a few more questions correctly on the PMP exam.

Wishing you all a great day!   Watch out for more posts bringing you closer to the finishing line!
