Overall advancement in the construction industry has not been spectacular in recent decades. Furthermore, delays in projects have been a very common issue in the construction sector. The Indian construction industry has grown significantly and follows the traditional methodology for the completion of construction projects. As a result, nearly 80–90% of Indian construction projects are hampered by time and cost overruns. The construction industry should adopt new construction management technologies like lean management and agile management for project performance like on-time completion, within budget, and promised quality. Lean construction is a way to design production systems in the construction environment with the aim of reducing time, effort, and material waste. The Last Planner System is one of the most effective lean construction tools to improve the construction management process. A combination of these systems would provide far more benefits than traditional methods of implementation. This study intends to fill that void by developing an LPS adoption framework for the construction sector. This study examines the implementation of the LPS over the traditional management system by analyzing the critical success factors and barriers' impact. Through relevant literature, structured interviews, and an industry survey, a total of 34 critical success factors and 25 barriers for LPS (Last Planner System) were identified. These parameters were then rated on a Likert scale by 66 experienced professionals using a questionnaire survey. This data is validated by industry LPS experts. An online questionnaire survey was carried out to collect data from the project manager, contractors, planning engineers, and site engineers. The frequency analysis method was used to analyze the data. The main results show that the critical success factors for implementing the Last Planner System were top management coordination, improper implementation plan, and defined roles and responsibilities for monitoring and implementation of the Last Planner System. On the other hand, organizational inertia or resistance to change, lack of commitment to Last Planner System implementation, or negative perspective towards new systems, were the main barriers to LPS implementation.
