A Simple Guide to the Triple Constraints Theory of Service Delivery Management

Time, scope, and money. These three make up the Triple Constraint Theory. For many years, it has been the standard within project managers.

If you’ve ever taken a project management course, you are probably familiar with this. But for those who are not, what does it really mean?

There are three challenges that service delivery managers must overcome to ensure that customers are satisfied. When it comes to meeting a project’s objectives, the project manager must effectively manage these three factors.


This is probably the most obvious of the three. It involves managing the money required to complete the project objectives. 

This includes budgeting and controlling costs throughout the entire project.

If a project exceeds its allotted budget then it will most likely exceed its scheduled completion date as well. 

So, when it comes to managing costs, you want to make sure you have an accurate understanding of how much money is available within your budget. Then, you can avoid any issues with cash flow later on down the road.


This is more about scheduling than budgeting. There are many ways to save on costs but only one way to save on time: speed up the schedule. 

The project manager must be able to manage demand and constraints. So, they can meet the deadline for the completion of the project. 

It’s important to note that this does not necessarily mean rushing through it. Rather, it means getting everything done that needs to be done in a timely manner.

Time constraints can affect either your schedule or your budget. So, make sure you have an accurate understanding of how much time you have before your deadline for completion.

That allows you to manage your schedule accordingly. If your schedule is off track, then you need to get back on track as soon as possible.


Scope means that you must deliver something valuable. But, it can also mean delivering something according to expectations. 

You should get your point across while still staying within your budget and timeframe.

In a perfect world, you would be able to deliver the project on time and on a budget without compromising the scope. But, that rarely ever happens. That’s why it’s the most important of the three constraints.

You have to be able to identify if your project is underperforming. If so, then you have to adjust it accordingly. 

This means making sure that you are managing your scope accordingly. You need to know what is going on with it at all times. 

If you are not aware of what is going on, then you could incur additional costs or even miss your deadline for completion.


The Triple Constraint Theory is one of the most effective theories in project management. But, it can also be one of the most difficult to manage as well. 

If you are not careful, then you could get yourself into trouble down the road. 

That’s why managers must be aware of how they are managing their projects and what they can do to improve upon them as well.
