Empirical research suggests that practicing Project Management knowledge may have a considerable influence on project success. Over the last half-century, time, cost, and scope have been inextricably linked to project success. The iron triangle in Project Management is the fundamental success criterion for a project. Indeed, almost every plan dealing with them includes a reference to three of them, demonstrating the importance of measures in project formulation. This is hardly unexpected given that the same features were commonly included in Project Management definitions throughout the same time period. Time and cost are informed assumptions that are often defined during planning phases, but the quality is a mentality that grows throughout the life cycle of the project. The iron triangle was a very well collection of three criteria used to assess a project's success. The degree to which the three limitations can be met determines the project's success.

Project Management Triangle

The triple constraint in Project Management is a critical principle that originates from the project's reasoning and guides the project's architecture. It is an essential component of the project's strategy, as well as the monitoring and controlling process group.

Despite the fact that the triple constraint concept is subject to interpretation, the research shows that the three key elements of the iron triangle in Project Management are project scope, time, and cost.

The time component of the project is in charge of the project's schedule and timeframe, the cost component is in charge of the project's resources and funding, and the scope element is in charge of the project's demands and duties. A time-restricted project is bound by its completion timeline, while a cost-constrained project is confined by its budget. The performance criteria of the deliverables constrained scope-limited ventures. As an intrinsic aspect, the iron triangle in Project Management promotes project quality.

The Project Management triangle is an excellent way to show how changing the triple constraint will affect essential project stakeholders. The triangle shape indicates that three constraints are connected and have trade-offs. If you change one aspect of the triangle, it changes the others. The quality of a project is based on how well the three parameters in the iron triangle work together. It is commonly asserted that triple constraint relationships lie at the heart of the most critical project decisions.

Triple Constraints of Project Management

The following factors must be looked into to figure out what is the iron triangle in Project Management:

1. Cost

The iron triangle's financial constraint is the cost, often known as the budget. Expenses may be split down into a variety of components, such as resources (both physical and human) and any external expenditures that impact a project. Costs are fixed in some cases and cannot be modified to meet needs.

For example, if a project component necessitates the employment of contract labor and the task takes longer than projected, the cost may rise. A client almost never has an unlimited budget (even if they might first claim to have one). Therefore, this constraint is relatively fixed.

To properly control project expenditures, Project Managers must create an initial budget and baseline that includes a combination of the following items:
 

• Data from comparable projects in the past to enable comparison

• Determining unit-level resource costs to help in projecting perspective changes

• Ranges of expected values for the lowest and highest values

• Vendor bid averages, if applicable

2. Scope

This comes from all tasks that must be completed in order to achieve the project's objectives. Controlling project scope is critical since modifications almost always have an impact on cost and timing.

For example, if the original request is for 10 hours of labor but a stakeholder requests an extra ten hours, the project's expenditures and timetable are likely to rise. This delicate balance of stakeholder requests must often be addressed, especially if stakeholders enter and exit the project.

3. Time

The time limit indicated by the iron triangle represents the project's expected completion. Time management is intrinsically related to task management because the calendar is broken down into particular tasks and their expected completion dates. To successfully manage time, Project Managers should identify tasks that must be done sequentially and are interdependent.

Time management consists of the following:
 

• Planning

• Identifying and describing all essential actions over the project's length

• Determining the correct sequence

• Estimating all required resources; the timing may be influenced if resources are scarce or otherwise occupied.

• Determining the length of each action

• Monitor the project's progress about the initial plan.

A project's timeline might be tight at times, adhering to a specific milestone or collection of data. Other projects could have a more flexible timetable. Clients seldom accept any delivery date, just as budgets are rarely endless.

Quality is the fourth variable in the "Iron triangle." When any of the other three variables, Time, Scope, or Cost, are adjusted, this component, which is placed in the center, is instantly impacted.

Advantages of Project Management Triangle
 

1. The Project Management triangle enables Project Managers to assess a wide range of external factors and their potential influence on one or more of the triangle's "variables."
    

2. Project Managers can keep track of the budget, timetable, and scope of their projects. This approach is easily adaptable to almost any project's criteria.
    

3. This model shows that Project Managers must understand how and where to make changes or compromises if any of the variables must change.
    

4. Many initiatives fail as a consequence of insufficient communication. A Project Management triangle is a graphical tool that Project Managers may use to show the link between all three variables, helping team members and stakeholders fully comprehend the needed changes.

Business experts believe that the triple constraint model was beneficial in a corporate culture concentrated on physical product manufacturing, but it is less appropriate in today's digital economy. Wei Lee, a Project Management specialist, did research in which he discovered that the triangle is oversimplified in today's more demanding environment. He underlines that a growing number of variables affecting a project are beyond the manager's command, making it practically hard to adequately manage the demands and repercussions of a project's requirements and implications.

Nevertheless, every projects and project teams aspire to the same result: satisfied customers and a successful outcome for their endeavor. Despite its age, the project constraint triangle is quite relevant and helpful in various contexts.

Conclusion

This article throws light on the question of what are the triple constraint of Project Management.  The management and execution of a project are critical to its success. As a result, competent Project Management is a vital essential player, with the iron triangle of Project Management constraints acting as the primary master. It is critical to complete each project on schedule and within budget while keeping a high level of quality. As a result, this Project Management triangle in certain businesses significantly impacts project success.
