The correct implementation of the Last Planner® System has been proven to increase the reliability of the planning and performance levels of projects by managing commitments. However, the current management of commitments in weekly planning meetings has not been sufficiently analyzed to teach people how to make reliable promises. Therefore, it is essential to deepen the measurement indicators of the Linguistic Action Perspective to generate reliable commitments that reduce uncertainty and variability in the projects. This study, based on "design science research", shows the first results of the indicators of the fundamental elements of language and action in construction projects in Chile. The results are an improvement over the previous indicators. Previous indicators have only been validated in a classroom setting, whereas this paper presents a validation based on case studies on actual construction projects which carry out weekly meetings using LPS. The authors invite the researchers around the world to measure and compare these indicators.
