Introduction. Ingenuity in management tactics nowadays is getting popular among the researchers in Project management field. Researchers are coming up with lots of updates regarding Management system with major and minor illustrates. Since last decade, the architecture, engineering, and construction (AEC) industries have observed the growth of the Lean Construction Management Systems and the rise of the Building Information Modeling (BIM). Not only individually but also in combination, they are acting as they have lots of synergy in their implementation pattern. There are numbers of case studies that show the benefits in Management functionality due to these systems. But how is that affecting the performance of Project or an organization? that is going to be the area of focus for the discussion.
The performance evaluation of categorized projects and their organization structure maturity comparison are the key parameters, which have been used to assess project management practices. Performance and maturity are generally evaluated based on the Project Management Maturity Model (in this case PMMM Third Edition). Which results in the maturity rating of the project management team practices on the Projects in various Project Management area of Knowledge. When those results are converted in the radar charts, Weakness and strength of each Project management system can be identified and compare with each other. After processing more than forty ongoing/completed Projects with these process, the clear picture of the behavior of each management has been explored.
Project Management System bifurcation
To evaluate the performance of the project management systems, the clear definition and the clear bifurcation must have done. Thus, based on various literature available, four different systems are identified to carry out performance analysis.
Figure 1. Bifurcation of Management systems according to their characteristics
Lean Construction management system
Project Management practices which are done with the help of Lean principals and Lean tools are classified under Lean construction management system.
BIM-based Management System
Project management practices which are implementing Building information modeling to achieve project objectives are classified under BIM-based management system.
Lean & BIM integration based Management System
Project management practices which are implementing both systems together are classified under Lean & BIM integration management system.
Conventional Management System
The project management practices which are not classified under above-defined categories are considered under conventional management systems.
Conventional Management System
From the obtained results of maturity ratings of the projects, it is clearly inferred that the conventional systems have the lowest maturity ratings in terms of performance of project management(PM) area of knowledge. As Shown in figure 2, they are lacking in all the PM areas of knowledge with having the average of 2.5 only.
Figure 2. Management maturity Radar Chart Conventional Projects.
The value of its rating indicates that there are in the phase in which they are know all standard practices about each area, but they are lacking in the execution. Implementation of standard practices required strong systems and tools along with the basic infrastructure to follow the standards. Lowest performances are observed in the risk management area. In which several explanations like inadequate education, Lack of experience and insufficient knowledge about the field has been found as the key reasons, during elucidation with professionals.
BIM Project Management System
As its name suggests, building information performed extremely well in Project Integration, Quality and stockholder management, still, it has some drawbacks as a Conventional management system in execution as shown in figure 3, BIM-based management systems are quite robust in visualization and communication areas.
Figure 3. Management maturity Radar Chart of BIM based projects.
But due to its inefficiency in execution and physical delivery environment, it’s maturity has been restricted to an overall average of 3.1 in all parameters suggest that the project following this system has knowledge about the standard system and through this system, we can target specific areas for improvement. Some of the areas including safety and Equipment management are yet unexplored in this system. The overall summary from the figure 4 suggests that heavy investment does not increase the maturity of the Management team.
Lean principal and tools based Management
Lean principal and tools are following the concept of reducing the waste and adding more value to the activity. There are 14 lean principals and various lean tools like Lean Project Delivery System TM and The Last Planer systems are available in the market. The essential assistance which is provided by the Lean construction and Management systems that help to grow the project management organization as shown in figure 4.
Figure 4. Management maturity Radar Chart of Lean principal & tools based projects.
The projects covered under the lean project management systems are found more mature and persistent in terms of maturity. However, risk management is the field which is not falling under the same foil. But as Whole Lean construction systems for management provides overall growth of maturity by covering all areas of Knowledge. Average maturity score for lean implemented management systems is 3.5, that expresses the performance of organizations under lean management has reached to the level of following standard practices in the current state.
Lean and BIM integration based Project Management
Lean and BIM integration focuses on every area of knowledge as it is functioning on both concepts. Characteristics of both systems reflect the maturity rating chart. Lean construction principals provide the balanced performance and BIM supports the technical assistance to achieve overall average maturity rating of 4.1 for the samples (see Figure below).
Figure 5. Management maturity Radar Chart of Lean & BIM integration based projects.
Both systems help each other to gain superior maturity than individual systems. However, it is observed that sometimes safety management is compromised. But as far as we concerned about the project management area of knowledge, the entire performance is better than individual systems.
Limited sight cannot restrict the pace of growth. Project management system’s maturity assessment reveals lots of clarity about system’s behavior on the overall maturity. The study clearly reveals that conventional management system’s performance is found significantly deprived that cannot sustain in the present scenario of growing construction Industry. Technical enhancement helps to improve maturity in a certain area of knowledge. But to increase the overall performance of the management system lean principals and tools are vital. BIM and Lean systems have various synergies between them. and it is derived from the research that Integration of advanced technology and sound principles leads to a balanced maturity empowerment in project organization. Thus, Lean & BIM integration is the direction to achieve our objectives rapidly and efficiently as its implementation causes progression in maturity.
