What issue arises if a project's scope is not clearly defined?

When a project's scope is not clearly defined, it leads to project creep, also known as scope creep. This phenomenon occurs when the requirements or objectives of the project expand beyond the initial goals without proper control or adjustments in resources, timelines, or budget. As new tasks and features are added without a structured process, the project can become increasingly complex and difficult to manage, often resulting in delays and misallocation of resources.

The lack of a well-defined scope means that team members may assume different aspects of the project or have varying interpretations of what needs to be delivered. This confusion can lead to continuous changes and additions to the project requirements, which can divert focus from the original objectives and thus extend the timeline and inflate costs. Understanding the significance of clearly defining a project's scope is critical for effective project management, ensuring that all stakeholders have a shared understanding of the project's goals and limits.
