What are the three main variables (or triple constraint)? What are the three main variables (or triple constraints) in project management?
If you’ve ever taken a project management course, you’ve probably already answered the question.
Since over 50 years, the triple constraint theory has been the standard for project management. It can be more complex when applied to real-life situations.

What are the Three Constraints of Project Management Management Management?
The “iron triangle”, and the “project management triangular”, are also known as “iron triangle” or “project management triangle”. They refer to the relationship between project scope, time, and cost.
Quality is the key to the iron triangle of project management (scope, time, and cost). Let’s take a closer look at each side to better understand the project triangle.
The scope of a project refers to the scope, breadth, reach, and limits of the work that will be done. It also includes the number of products and services that will be offered, along with the description of what is being done and how many. The complete SoW guide contains more information about scopes and guidelines for writing them.
Simply put, it is the time taken to complete the project/tasks within it.
The project cost is the amount (financial and otherwise) needed to complete the work. These costs can include labor, hardware, and software charges as well as any other fees.
How does The Triple Constraint work
The triple constraint is more than a cute mnemonic device. The three constraints of project management are based upon the fact that all three factors, scope, time, and cost, are interdependent.
Simply put, if you change one side of a triangle, it will also affect the other sides. This will bring you back to geometry class.
The most common triple constraint model shows that quality is dependent upon project scope, budget, and time spent. It places “quality” at the center of the triangle to illustrate this. You must adjust the sides to maintain a consistent quality level or in geometry class, an area within a triangle.
This idea is intuitive, math aside. If you need something faster (time), you will pay more. Sometimes you can save money (cost), by delivering a simpler product (scope).
The triple constraint is especially useful when speaking to clients, both in defining the scope of a project as well as when dealing with change requests. Digital agencies operate in a highly competitive market. They are often under pressure to produce a complete product as quickly as possible. as possible.
It is possible to do this in some situations, but the project management triangle reminds us that projects cannot be simultaneously comprehensive and cost-effective. We need to know our priorities before we can decide “what’s gotta stay”.
The iron triangle teaches us that a Venn Diagram for Dream Project (comprehensive, fast, and cheap) is often just that- a wish. A Triple Constraint is an example
