The article discusses methods of project progress control, focusing particularly on the Earned Value Management (EVM) method. The limitations of EVM are identified, to address them, such as Earned Schedule (ES) and Earned Duration Management (EDM), are explored. The issue of incorporating project quality is highlighted, and the grеy method of earned requirements is proposed as an alternative to existing project monitoring methods. The mathematical framework of the proposed method is presented, and its application in a project model using the MS Project environment is demonstrated. This research successfully addresses the significant scientific task of providing mathematical and informational support for decision-making, especially in adapting projects to changing stakeholder requirements. The research findings enable effective adaptation of projects to changes in stakeholder requirements using mathematical and informational tools. The use of MS Project tools helps to determine the progress of project progress in terms of meeting stakeholder requirements. For example, information on tasks lagging in terms of meeting requirements provides an opportunity to plan resources more efficiently under constraints.
