Defining What Are Project Constraints?
Project constraints are the limitations that impact a project's execution and overall success. These constraints, which vary depending on the project and industry, shape the project's boundaries and influence crucial aspects like timelines, budget, and deliverables.
Understanding and effectively managing these constraints is critical for any project manager aiming for successful project completion. Successfully navigating these limitations often requires a project manager to utilize their skills and training to navigate various factors. They're often interconnected, with one constraint affecting a team's ability to complete other aspects of the project. For example, if a project's cost increases, the team may limit the project's scope to stay within budget.
7 Types Seven Types of Project Constraints
While many factors can constrain a project, seven primary types of project constraints significantly impact project planning and execution:
These seven constraints are time, cost, scope, quality, benefits, risks, and resources, and managing these factors is essential for project success.
Time Constraint
Most projects have a clear deadline, which is a crucial measure of their success. Delivering on time is critical, as delays often result in increased costs and the need to adjust plans.
Project managers use their experience and knowledge to estimate project duration, considering potential delays, setbacks, and unforeseen events. Effective time management involves planning, scheduling, monitoring, and control.
Cost Constraint
A project's overall cost is another major constraint. Project managers must complete projects within the allocated budget. Cost management is an ongoing task, requiring constant monitoring to ensure spending aligns with budgetary requirements.
If issues arise, project managers develop strategies to limit spending and adhere to the budget. Strategies include analyzing historical data, adding new variables (such as inflation), researching resources, and studying the market to find the best deals.
Scope Constraint
A project's scope defines the deliverables the project manager guarantees to stakeholders. Discussions about scope often focus on the problems the project will solve.
The scope is typically defined at the project's outset to prevent miscommunication or modifications later. A tight deadline and a limited budget typically limit the project's scope, whereas a looser deadline and larger budget usually result in a more satisfactory outcome for stakeholders.
Quality Constraint
The quality constraint demands project teams complete successful work that meets all expectations. Quality is related to scope, and it ensures the deliverables meet stakeholder requirements.
Meeting quality standards ensures that the project meets its objectives and delivers the intended value to stakeholders. This constraint ensures projects meet the required standards.

Benefits Constraint
In many cases, project managers consider the benefits that their work offers to stakeholders and users. Project success often hinges on how well it delivers intended benefits.
Evaluating the benefits ensures the project aligns with strategic goals and provides the desired outcomes. This constraint focuses on the value delivered to stakeholders.
Risks Constraint
The risk constraint requires a manager to consider potential failures during project work and their effects on stakeholders. Risk management involves identifying, assessing, and mitigating potential issues.
Proactive risk management helps to minimize negative impacts and increase the likelihood of project success. This constraint focuses on potential problems.
Resources Constraint
Similar to cost, this constraint involves planning the required resources for a project and considering what's possible with resource allocation. Resource management includes budgeting, scheduling, and allocating personnel, materials, and equipment.
Effective resource management maximizes efficiency and reduces the likelihood of delays or cost overruns. This constraint is often intertwined with cost considerations.
Examples Project Constraint
Here are a few examples of situations where project teams experience constraint issues as they complete their work:
Construction Company Arena Update: A construction company wants to update an arena in time for a sports event. Engineers identify an unexpected issue with 15% of the stands. Since the time constraint is impossible to avoid based on the timing of the event, one or both of the other two may change to allow the project to wrap on time. The project manager can ask for a budget increase, which could allow the team to purchase additional resources to help them deliver the entire project on time. They could also ask for a scope decrease, for example, holding off a proposed bathroom update to focus on the stands instead.
Smartwatch Battery Life: A company plans on making the most inexpensive smartwatch on the market and delivering it by a certain date. Before the project wraps, though, a team member discovers that under the current time and budget restraints, the watch's battery life would be 20% lower than initially planned. With this information in mind, the project manager knows that they may have to modify the project plan to meet their goals. Given that the watch's inexpensive price is its main selling point, modifying the budget is not an option in this situation. Also, considering its low price point, it's likely that sales would not be greatly affected by the battery life decrease. Therefore, the project manager chooses to stay within the project budget and time constraints, while sacrificing the project's scope by delivering a slightly inferior product.
Managing How to Manage Project Constraints
Project managers use various strategies to estimate, understand, and manage each major constraint.
Time Management Constraints: Planning involves defining project goals, methods, and required equipment. Scheduling involves determining realistic timeframes for each task. Monitoring involves constant evaluation to ensure the project stays on schedule. Control involves making adjustments as needed to maintain the schedule.
Cost Management Constraints: Estimating and controlling costs includes labor, materials, licenses, and other expenses. Methods include analyzing historical data, adding variables, researching required resources, and studying the market for the best deals.
Scope Requirement Constraints: Agreeing on project requirements as soon as possible, documenting deliverables, and developing a system to manage changes are essential. Informing all stakeholders and creating an accessible forum for questions and concerns is also crucial.
