Avoiding cost overrun is key to closing a successful project. The quality of deliverables and a timely execution can go out the window if the project is delivered over budget.

Of course, it’s easy to say you’re going to keep a tight budget. But cost overrun can happen in so many places that keeping costs down can sometimes feel like a game of whack-a-mole.

What Is Cost Overrun?

The term cost overrun refers to unexpected costs that end up exceeding a project budget. Cost overrun can occur in any project and it’s particularly common in construction, manufacturing and software development projects. Cost overrun is also known as a cost increase or budget overrun and can be caused for several reasons.

Before we delve into the reasons that projects can go over budget, let’s look at project management software that can help you prevent cost overrun. ProjectManager is software that collects real-time data to help you better monitor your expenses. Our Gantt chart is a great way to plan and track your costs. All of this data automatically transfers to our other project views such as the dashboard. Unlike lightweight tools, there’s no setup required. Get started with ProjectManager for free today.

Main Causes of Cost Overrun

Cost management can be an exhausting task. As a project manager, you’ll constantly need to check your project costs to make sure things are going well at all times. In addition to this, you’ll also need to monitor other project constraints such as time, scope, risk and quality.

We’ve listed the main causes of cost overrun below so you can avoid this issue and deliver your projects on time and under budget.

  1. Bad project estimates: Cost estimation is critical for success in project management because every project manager must estimate all project costs before creating a project budget. Make sure to use all the tools at your disposal such as historical data or a panel of experts to help you define project costs. If your project budget is insufficient, you’re very likely to face cost overrun.
  2. Scope creep: Scope creep occurs when your project scope isn’t well defined. In simple terms, this means that you’ll have unexpected tasks popping up during the execution phase. Executing unforeseen tasks increases your costs, making it very likely to exceed your project budget and cause cost overrun.
  3. Poor risk management: Any project faces many potential risks. It’s the responsibility of the project manager and the project management team to create a risk management plan that describes all the potential risks and the mitigation strategies to be implemented if needed. When a risk management plan is not created, you can have unexpected risks affect your project, which brings costs up and therefore, causes cost overrun.
  4. Lack of communication: A project is an endeavor that requires teamwork and communication. As a project manager, you must be the glue that keeps your project sponsor, project team and project stakeholders together. Lack of communication can result in unexpected changes to the project plan or prompt other issues that could cause cost overrun.
  5. Poor change management: Without effective change management processes, scope creep can result in additional work and costs. Not prioritizing changes can divert resources and delay work, increasing overall project costs. The timeline and workflow can also be disrupted, impacting the budget.
  6. Equipment failures: This leads to downtime, which increases labor costs, but also can create extra repair or replacement costs. It also impacts productivity, which can lead to additional shifts and costs. Or it can create delays in delivery that disrupt the supply chain. Quality can also be affected.
  7. Unforeseen risks: Risk is always possible and can interrupt the project and create added costs. These risks vary from “acts of God,” such as environmental issues, to regulatory or market changes. Theft is also a risk that’s often neglected but can hurt production.
  8. Inflation and other economic conditions: This can be considered part of managing risk, but some issues related to inflation and the economy can be easier to predict. For example, managers can likely forecast resource scarcity and fluctuations in the price of resources. Still, many economic conditions can occur suddenly and must be prepared for in advance.
  9. Lack of project controls: Monitoring projects as they’re executed isn’t simply to keep stakeholders informed. It’s a way to measure the plan against actual progress, cost, etc. Therefore, when discrepancies are identified, controls should be put in place to get the project back on track before it negatively impacts the budget.
  10. Inefficiencies in the project team execution process: The project may be well planned, but if the team members fail to perform, these delays will generate additional labor costs. Or they might waste materials, which results in resource scarcity. This is why monitoring and controlling is so important. It captures these inefficiencies and responds quickly to them.
  11. Inefficient resource allocation: Project managers might allocate too many resources for certain tasks such as assigning two employees to a task when one is required. If this occurs throughout the project, the labor costs will exceed what was budgeted.
  12. Supply chain issues: There are issues outside of the project planning and execution that can end up costing the company more than expected. For example, supply chain issues. These can be a poor performance by contractors or suppliers, which causes delays, quality problems or rework. Any of these issues will result in cost overruns.

How to Avoid Cost Overrun

Cost overrun, or any sort of expense that pushes a project past the agreed-upon budget is something with which a project manager must be constantly vigilant. There are several ways one can prevent cost overrun.

Here are seven tips to help keep reigns on your budget.

1. Thorough Project Planning

The best way to stop cost overrun is to plan against it before executing a project. The more thorough and accurate your estimates, the more likely you’ll stay within budget. The project risks can be accounted for with an exhaustive risk management plan. When planning for any project, you must consider all possible scenarios and use historical data, interviews and experience. Once that plan has been detailed, the stakeholders of the project should sign off on it so everyone is on the same page in terms of expectations.

2. Know Your Vendors

Many projects require assistance from outside vendors, whether to help with specific tasks or supply materials and equipment. A relationship with any outside vendor opens your project up to cost overruns that are often beyond your control. This makes it critical to do due diligence before relationships are cemented.

First, understand the capacity of the vendor and if they’re going to meet your needs. When the vendor quotes a cost, make sure it’s accurate. Then, before signing the contract, do a bit of background-checking to see if the vendor meets deadlines and see what others have to say about working with them.

3. Keep to Planned Scope

Scope creep is one of the biggest threats to sending a project into cost overrun. Change requests always bog down the desks of project managers. These come from stakeholders or clients, but also from team members. They all have wants and needs. Many of them may be appropriate and even beneficial to the project. However, too many changes can drastically impact the project, making cost overruns unavoidable. Put thought into the big picture before you increase project scope.

4. Use a Project Planning Tool

It’s a given that a powerful tool will make a project manager’s work easier, add to the productivity of the project and increase efficiencies. It also assists in keeping cost overruns at a minimum. A scheduling tool like a Gantt chart can help keep the project on track and prevent cost overruns.

5. Keep Stakeholders Updated

If there isn’t a clear line of communication between stakeholders and project managers, delays are inevitable. Delays lead to cost overruns and there’s too great of a risk that work will start on the wrong task at the wrong time. This wasted time threatens to send the whole project off track.

Stakeholders, as well as teams, need proper communication, but each should get the right information. Teams want details while stakeholders want broad strokes to make sure the project is progressing as planned.

6. Monitor Progress

The real-time dashboard from ProjectManager is also ideal for tracking the progress of a project as it happens. Before issues become problems that threaten the project’s schedule and budget, they can be resolved. The real-time dashboard measures not only the project’s progress but the team’s workload and timelines for planned and actual completion, including project slippage and more.

7. Reassign Resources

If you discover a project that’s spending more than budgeted, you’re going to respond by reallocating resources. But you can also prepare for that scenario by evaluating resources beforehand and placing them where they’ll be most effective. This is especially true with your most valuable resource: your team.

By assembling the most experienced and skilled team members, you can have a more productive and efficient project. These resources might cost more, but if you’ve done your planning and set aside funds, you’ll save money on the backend when there are fewer issues to handle.

8. Make a Work Breakdown Structure

Another way to avoid cost overruns is by using a work breakdown structure. This hierarchical tool identifies all project deliverables and in so doing every task and subtask that produces them. This knowledge will lead to more accurate cost estimation, resource allocation and timeline management. Because it’s so thorough, a WBS is an essential tool to forecast costs.

9. Establish Project Controls

By monitoring the project as it’s being executed, and tracking performance, budget and schedule progress, project managers can quickly identify when there are discrepancies that will lead to cost overruns. These issues then can be quickly resolved to get the project back on track. Using project controls is a proactive way to intervene and keep the project running as planned.

10. Establish a Change Management Process

By formalizing the process of identifying, reviewing, approving or rejecting change in the project, those changes are evaluated for their impact on budget, scope and schedule. This change management process prevents unplanned modifications that could lead to cost overruns and ensures that only cost-effective changes are implemented. This reduces disruption to the project, which often has a steep price tag.
