A resource is usually a person, but it can also be a piece of equipment, materials, services, or even a room — whatever is required to complete a task. The amount of resources you have can affect the project scope and the time it takes to complete a project. If, for instance, half of your team comes down with the flu, you may decide to cut the scope so that the project can be accomplished by the remaining team members and meet its original deadline. Alternatively, you may decide to maintain the original scope and push out the project deadline.
