What are the three types of constraints that projects face; provide examples and suggest ways to address these constraints?

What will be an ideal response?

The three main types of constraints that a project manager faces are time constraints, resource constraints, and mixed constraints. Examples of each will vary.

In the time-constrained project, the work must be finished by a certain time, or date, as efficiently as possible. In the resource-constrained project, the work must not exceed some predetermined level of resource use within the organization. While the project is to be completed as rapidly as possible, speed is not the ultimate goal. The mixed-constraint project is primarily resource constrained but may contain some activities or work package elements that are time constrained to a greater degree.

Time constraints can be addressed by increasing the percentage of worked time until the due date by working overtime or on weekends and holidays. Increasing the labor pool through dedicated personnel or subcontractors or automating processes, buying more powerful or efficient equipment, or improving work methods can all help speed up a project. Resource constraints may be addressed by leveling a project or extending the time available. Mixed constraints can be addressed by some combination of these techniques.
