If the three constraints are well-balanced, the project is more likely to achieve high-quality results. On the other hand, if there is an imbalance in any of the constraints, the quality of the project may be compromised.

the project scope.Monitor for scope creep: Regularly review project requirements to ensure they align with the defined scope.Prioritisation
: Use a prioritisation method, such as
MoSCoW, to determine which features are essential, desirable, optional, or not required.Time management approaches
When managing project time, you can try these tips:
Critical path
: Identify the tasks that must be completed on time for the project to stay on schedule.
Resource leveling
: Optimise the use of resources to avoid overloading or underutilisation.
Timeboxing
- : Set a fixed time period for specific tasks or project phases.
- Agile sprints
- : Break the project into short, focused work cycles with specific goals.
- Cost control methods
- When managing project cost, you can try these tips:
| Implement time-boxing techniques to improve focus and productivity.Consider parallel processing of tasks where possible.Negotiate for deadline extensions when necessary. | Budget limitations |

| Limited budgets | can restrict resources, impacting the project’s scope and quality. |
| Solutions | Conduct thorough cost estimation during the planning phase. |
| Implement earned value management (EVM) to track project cost performance. | Explore cost-effective alternatives for resources. |
| Prioritise budget allocation for critical project components. | Balancing constraints may sometimes lead to |
| quality issues | in deliverables. |
| Solutions | Establish and communicate clear quality standards at the beginning of the project. |
| Implement regular quality checks throughout the project lifecycle. | Involve stakeholders in continuous feedback loops. |
| Allocate resources for testing and quality assurance processes. | With preparation of ways to address these hurdles, you will be one step closer to coping with the strain on the project management triangle. Keep in mind that this is where some creative strategising can help you maintain control of all these factors. It’s good to frequently ask “how are things going” and be willing to switch things around to keep them in balance. |
Review the project plan on a regular basis. This will help you to stay on track and make changes as necessary.

If you find that you are off track, you can always make adjustments to get back on track.Decisions based on information to revise project plans.Team collaboration and accountabilityProject managers can also foster collaboration and teamwork among team members by holding them accountable for their part of the work. When team members know that they will be held accountable for their work, they are more likely to collaborate with others to complete the project successfully. There are several best practices for collaborating and holding team members accountable, including the following:Assign clear roles and responsibilities to each team member. This will help everyone to understand what they need to do and be held accountable for their part of the project.Encourage team members to collaborate with each other. This can be done by setting up regular team meetings and encouraging team members to communicate with each other.Track team members’ progress and hold them accountable for their work. This can be done by regularly reviewing each team member’s progress and providing feedback.
Recognise and reward efforts that support successful constraint management.

Tailoring to the project context
Both books also discuss the need for tailoring of the project management approach . In the previous editions of the PRINCE2 manual tailoring always formed its own chapter but that has now been removed. Discussions of tailoring are now embedded within each process or practice chapter. In the What is PMP Certification? | How to Get Project Management Professional CertifiedPMBOK ®Knowledge Train
