Five phases of TPM implementation Phase 1 of TPM—Initial cleaning； At this stage, through thorough 5S implementation at the site and the repair of equipment, we transform our workplace into a neat, clean, comfortable, and aesthetically pleasing environment. Through the implementation of the first phase, the most important outcome was a change in employees’ mindset, an increase in their willingness to take action, enhanced execution capabilities, and the development of their ability to identify problems on site during the implementation process ； TPM Phase 2—Countermeasures for Difficult Points/Root Causes ； During the process of improvement, issues that were previously invisible often come to light; we address them and work on improving the elements around us, achieving tangible results, and strengthening our confidence amid the joy of success. At this stage, we have gradually cultivated our employees’ ability to make improvements. TPM Phase 3—Total Inspection ； The focus at this stage is to enable employees to gain a thorough understanding of the equipment as well as the production site they work in on a daily basis, and to establish an autonomous management system through regular inspections; furthermore, a mechanism for preventing problems before they occur is created through standardized daily management. The employees’ willingness to participate in management and their improved ability to make improvements on the job have laid a solid foundation for us to ultimately establish a system of autonomous management. TPM Phase 4—Improving inspection efficiency (visual management) ； To improve the implementation of our daily management, we should establish a visible management framework that is clear at a glance. The fourth phase aims to achieve this by using visual management as a tool to improve the efficiency of inspections and boost labor productivity. TPM Phase 5 – Establishment of a self-managing system ； By implementing TPM over the long term within a company, we can achieve our goal of establishing a self-managing system with full employee participation. Under this system, we can not only resolve various “icebergs” on our own, but also proactively prevent their occurrence, thereby achieving the goal of “zero” faults, defects, and waste. Reasons for the failure of TPM implementation: 1. Lack of appropriate technology. Enterprises lack TPM technical expertise, and are unable to resolve technical issues. For example: they do not truly master some of the necessary implementation methods, control methods, testing techniques, etc., for TPM. 2. Lack of management tools. This includes support from senior management, appropriate TPM promotion strategies and communication, as well as corresponding human resources policies. Without integrating TPM into daily management, true continuous improvement is not possible. 3. Treat TPM as a “sport” and engage in tactical combat. There is a rush to achieve results, a lack of the \"TPM mindset,\" which seriously violates the fundamental philosophy of continuous improvement in TPM; moreover, the strategies and approaches for advancing TPM are incorrect. 4. Overemphasizing the “tool”. There is no deep understanding of TPM; instead, the tools are simply copied, with those tools themselves being regarded as the goal, which results in an imperfect integration of the tools with the actual situation of the enterprise. Just as one drinks coffee with a spoon, but the spoon itself is not the coffee. Appendix: The Application of Japan’s TPM Management Model in Construction Enterprises 1. Implementing the “5S Activities” \"The environment influences people,\" has always been a fundamental principle in behavioral science; it is the responsibility of every manager to create an environment that facilitates improved work quality and efficiency. The so-called “5S” refers to “Seiri,” “Seiton,” “Seiso,” “Seiketsu,” and “Shitsuke.” Since Japanese pronunciations all start with “S”, it is called “5S”. The following is an item-by-item analysis. First, organize. Separating the materials, tools, equipment, and reports that are needed from those that are not, and then getting rid of the unnecessary items, is the first step in improving the environment. Railway construction companies accumulate a considerable amount of equipment and materials due to changes in the projects they work on; over a certain period of time, this not only fails to generate value for the companies but also takes up space and incurs maintenance costs. Such equipment and materials should therefore be disposed of. Second, rectification. Place the desired items in the correct quantities and locations. Materials in the material room, tools, and oils should be arranged in proper quantities and neatly organized; rails and sleepers should be stacked in appropriate quantities as well. Equipment must be stored in categories, and machinery that needs repair should be placed in designated areas – random storage is not allowed. Third, cleaning. Clean the dust and dirt from the construction site, the surrounding area, equipment, and materials. After work, operators spend about 10 minutes cleaning the machinery they use. Fourth, cleaning. It refers to thorough maintenance after “organizing,” “tidying up,” and “cleaning.” Cleaning is the first step in safe production. Fifth, literacy. It refers to developing good working habits, abiding by the organization’s rules and regulations, and making every effort to enforce them. One’s sense of obedience and spirit of teamwork should be akin to that in the military. “The “5S” initiative is the first step in total equipment management; if it is not carried out properly, any attempts at reform will be meaningless. The “5S” initiative relies on all employees. 2. End-of-month work meetings and daily shift handovers Planning is the primary function of management; it serves as a bridge between the current situation and goals, and it ensures that those goals are achieved. To maintain construction operations, it is necessary to carry out planned maintenance and repairs of machinery. At the end of each month, the civil engineer in charge of construction, the mechanical engineer in charge of machinery, and the electrical engineer in charge of power systems meet together for a work meeting. They first summarize the actual work carried out that month, discuss the existing problems, and finally outline the work plan for the following month. Both the construction plan and the machinery maintenance plan are presented in the form of a report, making them easy to understand at a glance. Management is a dynamic system, and deviations may occur during the implementation of plans; therefore, adjustments must be made in a timely manner based on the actual situation. The daily handover meeting system can be used to supplement and improve the implementation of monthly plans. A shift handover meeting is held at 5 p.m. every day, where civil, mechanical, and electrical engineers report to the company manager on the work completed that day as well as the plans for the next day. The work completed and the plans are presented in the form of reports. The implementation of shift handover meetings ensures that all tasks are carried out in a highly planned and directive manner, enabling company managers to make strategic decisions from a distance. 3. Clear division of labor and unified authority Organizational functions are an important aspect of management; an effective organization must ensure unity among responsibilities, duties, and authorities. Therefore, TPM management requires a very clear division of roles among managers. Each construction team should have only one project manager, with no deputy positions. There should be two civil engineers, one responsible for construction and the other for surveying, as well as one mechanical engineer and one electrical engineer. Each shift is assigned a technical supervisor who is responsible for providing guidance on the construction work and filling out the daily construction report for that shift. Each engineer has clear job responsibilities, manages the tasks under their responsibility on their own, generally does not interfere with one another, and enjoys full autonomy. The engineer directly assigns tasks to the technicians or team leaders, providing technical instructions, safety guidelines, and schedule information. The company manager doesn’t handle construction details; he only handles coordination. Each engineer has the authority and responsibility to carry out integrated management of production and technology. Whoever is responsible for something must take care of it properly. Whoever is responsible for making a decision should be the one to make it. The manager’s responsibility is to conduct two meetings well, namely the daily handover meeting and the monthly work summary meeting. 4. Daily operation report and weekly mechanical inspection The driver must fill out the \"Daily Mechanical Operation Report\" every day, indicating when the machinery is in use and when it is under maintenance ； How much fuel was added and what problems existed are all clearly recorded in the operation log. At 8 a.m. every day, the driver delivers the daily reports to the engineer. A comprehensive inspection of the machinery is carried out once a week, namely the weekly check. The weekly inspection is carried out by engineers together with drivers, who carefully observe and examine the machinery and various components according to the items listed in the weekly inspection sheet. The items checked in the weekly inspection form vary depending on the machine. By implementing daily operation reports and weekly inspections, on the one hand, it provides a basis for maintenance work, and on the other hand, it improves the skills of drivers. Through repeated weekly inspections, drivers are generally able to achieve the ‘three understandings and four skills’, after which they can carry out weekly inspections on their own. Any issues identified during the weekly mechanical inspection must be addressed promptly, and it is not allowed for the same problems to reappear during the next weekly inspection. 5. Daily inspection system: Mechanical and electrical engineers must inspect all mechanical and electrical equipment on a daily basis to identify potential faults in a timely manner, so that they can be resolved before the equipment fails. Nearly 70% of potential failure risks can be identified from the operation daily reports and weekly mechanical inspection forms filled out by the drivers; combined with daily inspections, these risks can essentially be eliminated, resulting in a failure-related downtime rate for the machinery that is close to zero. 6. Mandatory maintenance: In addition to routine maintenance during downtime, major construction machinery must undergo two rounds of mandatory maintenance per month. It is generally scheduled to take place on the weekdays of the second and fourth Sundays of each month. On this day, no construction work is scheduled. On the mandatory maintenance days, mechanical and electrical engineers organize skilled repairmen to carry out maintenance and repairs on the machinery that is difficult to fully service under normal circumstances, with the assistance of drivers. 7. Individual unit accounting: A card is created for each piece of equipment. Carry out single-unit cost accounting management, and conduct monthly statistics and summaries on the equipment’s usage, maintenance, repairs, and various consumptions. Conduct a cost-profit analysis by the end of the month. The profit and loss situation for each individual machine is published on a monthly basis, and employees are rewarded or punished accordingly. Implementing unit-cost accounting can effectively control the consumption of spare parts and fuel, manage repair costs, and improve the integrity and utilization rate of machinery.
