AB  - Last planner® system (LPS) is an effective tool for continuous monitoring and improvement of the planning. One of the main parts of LPS is the constraint removal discussion. Identifying and removing the constraints before the execution can influence the reliability of the plan and can ultimately improve the project performance. Previous research works have indicated the use of Information theory to quantify the effect of constraint removal discussion on the performance of the weekly work plan while using Percentage Plan Complete (PPC) as an indicator of work plan reliability and considering a limited range of constraints categories. Earlier studies have proved that Task Anticipated (TA) and Task Made Ready (TMR) are better indicators of the project duration than PCC. In this paper, the researchers have used information theory to assess the effect of the constraint removal discussion on PPC, TA, and TMR of the construction projects while considering a wider range of constraints. The results signified that the important constraint categories vary for improving PPC and improving TA & TMR. Identifying and discussing the main constraint categories could improve the work plan reliability indicators up to 18%. The framework can be used repeatedly and the results can contribute to improving the effectiveness of weekly meetings in the future.
