Lean practices have shown their potential in reducing environmental, economic, and social impacts during the construction phase, with an increase in the parameters of sustainability in the development of projects. Last planner system® (LPS) has gained prominence in recent times for its ability to increase the possibility of timely construction project delivery. However, LPS is yet to gain sufficient confidence from industry for wide spread implementation. The present paper intends to present the benefits, critical success factors, barriers and drawbacks of the LPS with the intent of promoting the applications in industry. An extensive review of literature published over last two decades has been done. The study has identified that improvement in the reliability of planning, visualization of future and planning transparency, reduction in project time as the major benefits, commitment from top management, training of the participants as the critical success factors, resistance to implement LPS, involvement of many parties in the project as the most significant barriers of implementation. The study has also presented the difficulties faced during LPS implementation which if addressed shall be able to improve the process of implementation, translate to project success, and instil confidence in the industry practitioners to implement the system widely.

建筑项目实施last planner system®的经验

随着项目开发中可持续性参数的增加，精益实践已显示其在减少施工阶段的环境、经济和社会影响方面的潜力。最近，Last planner system® (LPS) 因其能够增加及时交付建设项目的可能性而备受瞩目。然而，LPS 尚未获得业界对广泛实施的足够信心。本文旨在介绍 LPS 的好处、关键成功因素、障碍和缺点，旨在促进工业应用。对过去二十年发表的文献进行了广泛的审查。研究表明，提高规划的可靠性、未来的可视化和规划透明度，项目时间的减少是主要的好处，高层管理人员的承诺，参与者的培训是成功的关键因素，实施 LPS 的阻力，项目中多方参与是实施的最大障碍。该研究还提出了 LPS 实施过程中面临的困难，如果解决这些困难，将能够改进实施过程，转化为项目的成功，并为行业从业者灌输广泛实施该系统的信心。
