Constraints may be defined as anything which is a hindrance to the operations of the project team or forces the team to operate in a certain way. Constraints typically create a barrier which prevents the project manager from achieving predetermined objectives. Resource constraints usually result in limited budgets; it constitutes a significant barrier to the success of the project. Limited resources cause a reduction in the main materials of the team and could impose limits on the project's scope. For instance, a particular component X may be excluded from the project because there are not sufficient resources to obtain it. The client usually does not have much money to spend on a particular project. In the same way, the company can only take on a specific task for a particular price. To some extent, it would not be worth taking on more. There are other disadvantages of resource constraints. They may lead to delays in the project, large errors resulting from rushed operations, the loss of valuable human resources and high levels of employee stress. In order to address the issue of resource constraints, the project manager should have a viable resource plan. Such a plan allows the manager to carefully examine all future activities and facilitate the development of a strategy, which favors the effective distribution of the limited resources available. A resource plan would also help the project manager evaluate the team’s performance in contrast to the projections made. A resource plan is essential to the proper alignment of activities and helps the project manager make the right decision in terms of staffing. The hiring of new employees should be properly timed because reactive hiring is detrimental to the well-being of the company. Reactive hiring would imply that the manager's plans and projections are not adequate.
