To continue my series on the nine project management knowledge areas, I would like to discuss the topic of project cost management. Cost management involves knowing the financial and human resources required to complete a project within an approved budget.
The PMBOK describes three areas or processes for effective cost management:
- Estimate Costs
- Determine Budget
- Control Costs
Estimating the Costs
The first step in cost management is to estimate the costs of each activity in the project. Costs include both human resource and physical resource costs. Because this step often occurs in the planning phase, it is important to understand that the estimated costs are your “best guesses” at the actual costs of each activity.
To get a good guess at the costs you can use one of the following techniques:
- Analogous Estimating: estimates are based on past projects. It uses actual costs from a similar finished project to estimate the costs of the new project. The accuracy of these estimates will depend on the similarities between the new project and the old project.
- Parametric Modeling: estimates are based on mathematical formulas, typically following a Regression Analysis or Learning Curve model. The accuracy of these estimates depends on the assumptions made.
- Bottom-up Estimating: estimates are based on individual work item cost and duration estimates. This involves estimating the smallest activities and then adding them up to create an estimate for the whole project.
Determining the Budget
Using your best-guess estimates, the next step is to create a realistic project budget. In this step, you will determine the cost baseline and the funding requirements for the project. A good project budget will help you make key decisions with respect to the project schedule and resource allocation constraints.
To determine the project budget, the PMBOK suggests using several techniques:
- Cost Aggregation: requires you to aggregate or combine costs from an activity level to a work package level. The final sum of the cost estimates is applied to the cost baseline.
- Reserve Analysis: requires you to create a buffer or reserve to protect against cost overruns. The degree of protection should be equivalent to the risk foreseen in the project. The buffer is part of the project budget, but not included in the project baseline.
- Historical Data: requires you to think about estimates from closed projects to determine the budget of the new project. This is very similar to analogous estimation described earlier.
- Funding Limit Reconciliation: requires you to adhere to the constraints imposed by the funding limit. The funding limit is based on the limited amount of cash dedicated to your project. To avoid large variations in the expenditure of project funds, you may need to revise the project schedule or the use of project resources.
Controlling the Costs
Good project managers will carefully monitor the cost of their projects. This includes watching to see where actual cost has varied from estimated cost. Cost control also involves informing the stakeholders of cost discrepancies that vary too much from the budgeted cost.
To effectively control project costs, you will need to regularly monitor and measure the performance of the budget and revise forecasts as required. The PMBOK suggests several tools and techniques to help control costs:
- Earned Value Management: uses a set of formulas to help measure the progress of a project against the plan.
- Forecasting: uses the current financial situation to project future costs. The forecast is based on budgeted cost, total estimated cost, cost commitments, cost to date, and any over or under budgeted costs.
- To-Complete Performance Index (TCPI): represents the level of project performance that future work needs to be implemented to meet the budget.
- Variance Analysis: involves analyzing the difference or variance between the budgeted costs and the actual costs to indicate whether the project is on budget.
- Performance Reviews: used to check the health of a project. Includes an analysis of project costs, schedule, scope, quality, and team morale.
By learning how to estimate costs, determine budgets, and control costs, you can be a better project manager and leader. Effective cost management will you help you get projects done on time and under budget, the golden ticket for any successful project manager.

The knowledge area of time management typically refers to "the skills, tools, and techniques used to manage time when accomplishing specific tasks, projects, and goals." To become an effective time manager, you should be able to clearly understand the activities of the project and have the necessary skill set to plan, schedule, and control a project timeline. Along with these skills, you must also be able to utilize time management tools to help you analyze, measure, and assess your time management techniques. Keeping all of this in mind, may I suggest four steps to help with project time management?
The knowledge area of Scope Management is all about making sure that the project includes only the work required to complete the project successfully. To be effective at scope management, you must learn to control what is and what is not in the scope of the project. Below are some of the best practices for successful scope management.
A work breakdown structure or WBS is a graphical representation of the hierarchy of the project. The WBS forces the project team to think through all levels of the project and identify the major tasks that need to be performed for the project to be completed on time. By starting with the end objective and then successively subdividing it into manageable steps or components in terms of size, duration, and responsibility, the WBS provides a high level view of the entire project. Furthermore, the framework makes planning and controlling the scope of the project much easier since you have a graphical chart to reference point for the tasks and subtasks needed for each phase of the project. As a general rule of thumb, no task within the WBS should be less than 8 hours or more than 80 hours.
Integration management is the knowledge area that includes processes that are required to ensure that all the projects components are coordinated correctly in order to achieve the project goals. To help you better coordinate and manage the various elements of the project, may I suggest four keys to integration management?
Scope Management – Scope statements, work breakdown structures, mind maps, statements of work, requirements analyses, scope management plans, scope verification techniques, and scope change controls.


With such a broad definition of resources, you need to be able to quickly and effectively move around resources to meet the varying needs of each project. The best way to do this is to let project management software do the work for you. With project management software, you can manage multiple projects from a single location. Good software allows you to quickly create projects and task lists, organize teams, and better control the flow of information and resources, saving you valuable time and money.
Resource grids let you see in a calendar where your team is over- or under-utilized and where each team member is allocated. By seeing each team member, you can quickly identify resource conflicts and then resolve those conflicts with the Resource Leveling tool. With the click of a button, resources are reallocated and project completion dates are automatically adjusted to accommodate for the new resource restrictions. Additionally, the Capacity Planner lets you see the impact of adding to or changing your current plan. You can adjust the schedule or the resource budget and push your changes "downstream" to your project managers.
