Projects cost money. You pay employees their salaries and contractors their fees. You buy materials and tools. You rent space and pay for equipment. You allocate funds for travel and other expenses.
If you have a big budget, you can employ more people to speed up project delivery. Or use better materials. Or better technology. If the budget is tight, you may have to scrimp and save here or there to provide wiggle room for more important aspects of the project.
Bottom line: No matter how big or small the allocated project budget, you have to keep expenses within the project’s financial limits -- exactly why cost management is such a critical piece of overall project management.
Project cost management, in a nutshell, is estimating the project’s budget and putting in place cost monitoring and control measures to keep expenses from exceeding that budget.
It’s one of the 10 knowledge areas within the Project Management Institute’s PMBOK Guide, a collection of project management standards and best practices, and is made up of four processes (more on these below), namely:
Small businesses fail for many reasons, and cash flow or funding problems often top the list. So, when working on projects, project managers should carefully watch where the money goes.
Budget plans can go haywire in a number of ways -- suddenly sick critical personnel, late materials shipment, inaccurate expense forecasts, factors totally out of your control, etc. -- but if you’re paying close attention, and you have a cost management system in place throughout the duration of the project, you’re likely to make it through unscathed.
There are three major cost management advantages for small businesses.
According to the PMI’s 2018 Pulse of the Profession, the average percentage of budget lost when a project fails is between 27% and 37%, while the average percentage of projects completed within budget is between 43% and 67%.
Organizations with mature value delivery capabilities -- meaning those that can quickly adapt to changing market conditions, balance creativity and efficiency, and espouse continuous improvement -- fare better than their counterparts with low value delivery maturity.
This simply emphasizes just how crucial cost management is to every project. It may not prevent your project from going over budget, as the numbers above show, but it can help keep the overrun to a manageable level.
A dependable cost management strategy lets you estimate, with a certain degree of accuracy, how much money is needed for each project task, which you can then track, manage, and control throughout the project’s life cycle.
It also allows you to effectively allocate resources when and where they’re needed so work goes as planned, without delay.
Project cost management ensures you don’t overspend, or it will at least allow you to contain spending as much as possible, on projects -- all while meeting timeline expectations and ensuring project quality. A penny saved is a penny earned, after all.
If you’re a small business operating on a small budget, effective cost management enables you to make the best use of your finite resources and pursue other value-adding projects.
Inefficient project cost control is one major reason projects fail. But project cost management isn’t about control alone. According to the PMBOK Guide, it’s made up of four processes, each equally important.
A project plan contains several subsidiary plans, and the cost management plan is just one of them. Other secondary plans are the resource management plan, the communication plan, and the risk management plan, to name a few.
During the plan cost management process, the project manager, with the help of the project team, creates a project cost plan that outlines how project expenses will be estimated, allocated, communicated, and controlled. Again, the aim is to prevent cost overruns.
A cost management plan can be customized to fit your project’s specific needs, but it typically includes:
To create your project management plan, you’ll need these input documents:
Estimating costs is the process of approximating or forecasting the necessary financial resources to complete a project. To do that, you need a thorough understanding of the project’s scope, who’s doing which work, and the required length of time to complete the work.
Let’s say you want to digitize your company’s data. Depending on data amounts and how soon you want everything digitized, you may need a few people to a few dozen people working day and night to finish the work. From there, you can start estimating your costs.
Common techniques used for cost estimation include:
The project budget is the total amount you’re allowed to spend on a project and is based on the cost estimate created in the previous process. The budget also serves as the cost baseline to compare the project’s cost performance against.
To determine the budget, you need the following information:
Techniques and tools used to determine the project’s budget may include:
Cost control is the process of tracking and monitoring actual project expenses, and then comparing them against the cost baseline to see if the budget needs to be adjusted.
Said differently, it compares how you’re doing budget-wise versus how you should be doing. This is so you can immediately spot plan variances or deviations, then make the necessary corrective adjustments to minimize risk.
Take note that adjustments to the project’s authorized budget follow an agreed-upon change control process.
Some tools and techniques to control costs include:
Operating under constrained circumstances is not a rarity in project management. It’s, in fact, a reality project managers contend with on an ongoing basis. But with the right cost management techniques up their sleeves, project teams have better chances of meeting agreed-upon budget guidelines.
