How should changes in the project be managed according to best practices?

Managing changes in a project according to best practices involves a structured and formal approach to ensure that all modifications are effectively controlled and documented. The best practice of documenting changes through a formal change order establishes a clear record of what changes were made, why they were necessary, and how they impact the project scope, timeline, and budget.

This formal documentation serves multiple important functions. First, it provides a reference that can help manage stakeholder expectations by clarifying what has been agreed upon. Second, it helps maintain accountability, as all parties involved have an agreed-upon record of the changes. This reduces the likelihood of misunderstandings or disputes later on. Finally, formal change orders facilitate better analysis and decision-making, allowing project managers to assess the implications of changes comprehensively before implementation.

The other options lack the structured approach that is essential for effective change management. Ignoring changes could lead to unaddressed issues that escalate into larger problems, while immediate implementation without documentation may result in chaos and misalignment with project goals. Informal discussions may provide some value but do not create the necessary accountability or clear communication pathways that formal documentation does.
