Scope creep has a significant impact on construction projects, often leading to delays, budget overruns, and reduced project quality. The main objective of this paper aims is to review, explore and integrate the key factors contributing to scope creep and its impacts on project outcomes. Hence, the most proactive and effective strategies which can be introduced to mitigate that impact. Some of these key factors such as inadequate project scope definition, unmanaged stakeholder communication, and changes in project requirements are identified as primary contributors to scope creep. These factors are illustrating that how poor planning, ineffective communication, and a lack of coordinated management efforts have significant adverse effects on project timelines, costs, and performance. Various strategies of scope creep, such as clear and detailed scope definition at the outset, early and ongoing involvement of stakeholders, and the implementation of rigorous change management processes throughout the project lifecycle have signific proactive strategies. By addressing the root causes of scope creep and improving communication and planning practices, these strategies aim to minimize its negative impacts on construction projects. This study is adding value to the project managers and construction professionals, by introducing practical recommendations to mitigate scope creep and improve project outcomes in the construction, particularly in Egypt.
