How to Resolve Resource Availability Conflicts in Microsoft Project

Resource availability conflicts are a common occurrence in project management, especially when dealing with complex projects. Resource availability conflicts occur when multiple tasks require the same resources at the same time, causing delays and cost overruns. These conflicts can be avoided by properly scheduling resources in advance, but when they do occur, it is important to resolve them as quickly as possible to keep the project on track.

In this article, we will discuss how to resolve resource availability conflicts in Microsoft Project, one of the most popular project management tools used today. We will cover the basic concepts of resource allocation, identify common causes of resource conflicts, and provide step-by-step guidance on how to resolve these conflicts using Microsoft Project’s powerful resource management features.

Understanding Resource Allocation in Microsoft Project

Before we dive into resolving resource conflicts, it is essential to understand the basics of resource allocation in Microsoft Project. Resource allocation involves assigning specific resources to individual tasks within a project, such as people, equipment, or materials. To ensure that resources are assigned efficiently and effectively, Microsoft Project allows you to define resource types, assign resources to tasks, and track resource utilization throughout the project life cycle.

The key to successful resource allocation is to balance resource availability and project requirements. When resources are overutilized or underutilized, it can lead to conflicts that delay the project and increase costs. To avoid these conflicts, project managers must carefully monitor resource allocation and make adjustments as necessary.

Identifying Resource Availability Conflicts in Microsoft Project

The first step in resolving resource availability conflicts is to identify when they occur. In Microsoft Project, there are several indicators that can help you identify conflicts, including:

  • Overallocation: This occurs when a resource is assigned to more hours of work than are available in their schedule.
  • Underallocation: This occurs when a resource is assigned to fewer hours of work than are available in their schedule.
  • Double booking: This occurs when a resource is assigned to more than one task at the same time.

To identify these conflicts in Microsoft Project, you can use the Resource Sheet view or the Resource Usage view. The Resource Sheet view displays all resources and their assignments, while the Resource Usage view displays each resource’s work hours over time. By reviewing these views, you can quickly identify any overallocation, underallocation, or double booking conflicts.

Resolving Resource Availability Conflicts in Microsoft Project

Once you have identified a resource availability conflict, the next step is to resolve it. There are several ways to resolve resource conflicts in Microsoft Project, including:

  1. Adjusting task schedules: If a task is causing an overallocation conflict, you can adjust its start and end dates to reduce the resource’s workload. You may also need to adjust the schedule of other tasks that depend on this task to maintain consistency.
  2. Reassigning resources: If a resource is causing an overallocation or double booking conflict, you can reassign them to another task with lower priority or a different timeframe. Another option is to add additional resources to the task to spread the workload across multiple resources.
  3. Leveling resources: Microsoft Project has a built-in feature called resource leveling, which automatically resolves conflicts by adjusting task schedules, reassigning resources, or adding new resources as needed. To use this feature, go to the Resource tab and select “Level All.” Microsoft Project will then analyze the project and resolve any resource conflicts automatically.
  4. Splitting tasks: In some cases, it may be impossible to resolve a resource conflict through the above methods. An alternative solution is to split the task into smaller pieces and assign them to different resources. This approach requires careful planning to ensure that each piece is completed on time and in the correct sequence.

It is important to note that resolving resource conflicts may require you to adjust the project plan, which can impact the overall schedule and cost. Therefore, it is essential to communicate any changes to stakeholders and get their approval before making any adjustments.

Best Practices for Resource Allocation in Microsoft Project

To minimize the occurrence of resource availability conflicts in Microsoft Project, there are several best practices that project managers should follow:

  • Define resource types: Before assigning resources to tasks, define resource types such as equipment, materials, and people with different skill sets.
  • Estimate resource requirements: Identify the number of resources required to complete each task and ensure that they are available during the scheduled time frame.
  • Assign resources carefully: Carefully assign resources to tasks based on availability, skill set, and priority.
  • Monitor resource utilization: Continuously monitor resource utilization and adjust assignments as necessary.
  • Use resource leveling: Whenever possible, use Microsoft Project’s built-in resource leveling feature to automatically resolve conflicts.

By following these best practices, project managers can avoid most resource availability conflicts and keep their projects on track.


Resource availability conflicts can be a significant challenge for project managers, but with the righttools and techniques, they can be resolved efficiently. In Microsoft Project, project managers have a range of resource management features at their disposal to identify, analyze, and resolve conflicts. By understanding the basics of resource allocation, identifying conflicts early on, and following best practices for resource allocation, project managers can minimize delays and cost overruns and ensure that their projects are completed on time and within budget.
