Luobian Huayuan Sanming Workshop - Class 1 (2025 Cohort) - Lesson 3: "Management Accounting in TPS"
On October 18, 2025, the third lesson of the first Luobian Huayuan Sanming Workshop, titled "Management Accounting in TPS," was held as scheduled in the Luobian Fiberglass Employee Activity Room. This training session delved deeply into the core role of management accounting in business operations, uncovering the "secrets of profit and cash flow" behind the Toyota Production System (TPS).
Previous Results: Steady Progress on Policy Plans
At the beginning of the course, the Mingyang, Ganfeng, and Luobian Business Units delivered in-depth reports on the practical outcomes from the previous lesson on "Policy Management." Invited mentor Mr. Luo Yijun from Oufeng Consulting fully affirmed the achievements of each team in his comments, laying a practical foundation for subsequent lessons.
Management Accounting: The Mindset Shift from 'Bookkeeping' to 'Management'
The core of management accounting is value creation. Unlike traditional financial accounting's focus on bookkeeping and reporting, its essence lies in being a management system that uses data as its language, processes as its path, and profit and cash flow as its outcomes. Five Toyota-affiliated Fortune Global 500 companies utilize management accounting tools to translate management objectives into production practices, achieving cost control and efficiency improvements. Their core "management code" consists of three formulas:
Return on Assets (ROA) = Profit Margin × Asset Turnover
Profit Margin = Net Profit ÷ Sales Revenue
Asset Turnover = Sales Revenue ÷ Total Assets
Mentor Luo Yijun emphasized that when sales revenue is constrained, enterprises need to focus on "reducing costs, increasing turnover, and boosting profits," with the key to cost reduction lying in the elimination of waste.
Cost Structure: The Management Progression from 'Reduction' to 'Improvement'
Cost structure is divided into production costs (direct materials, direct labor, manufacturing overhead) and non-production costs (administrative, sales, etc.). Mentor Luo emphasized: identify the top 3-5 wastes as key targets for improvement. "Kaizen" (improvement) focuses more on being systematic, continuous, and collaborative. Cost management needs to distinguish between easily imitated (achieving industry average) and difficult to imitate (striving for industry best) aspects. In manufacturing, manufacturing costs often account for over 80% of total costs. Reducing manufacturing overhead means reducing waste (corresponding to the "Seven Wastes"). At the organizational level, break down process barriers, promote process flow, achieve fixed cost minimization, and improve space and time efficiency.
Profit ≠ Cash Flow: The Essence of Management is 'Time Management'
The essence of management is managing time. Cash flow turnover rate relates to the process cycle time. It can be improved without additional equipment investment by shortening changeover times, reducing stagnation, and optimizing processes, thereby improving cash flow. Cash flow is the lifeblood of an enterprise. Profit does not equal cash flow: profit is an accounting concept, while cash flow is the baseline for survival. This is why a company can be profitable on paper but often "short of cash."
The Seven Wastes: Identifying and Eliminating 'Cash Flow Killers'
TPS categorizes production work into value-added work, waste, and incidental waste. Among these, the "Seven Wastes" are key factors affecting cash flow:
Overproduction
Defects / Rework
Overprocessing
Transportation
Inventory
Motion
Waiting
Overproduction is not only the greatest waste but also an "invisible killer" of cash flow. Identifying these wastes and gradually eliminating them through "Kaizen" is the starting point of lean management and a key path to improving cash flow.
Rooted・Transformed・Win-Win: Inspirational Growth from Electrician to General Manager
In the "Sharing Café" segment, Mr. Zhang Yunzhong, General Manager of the Luobian Fiberglass Business Unit, shared his story titled "Rooted in the Enterprise for Two Decades, Growing Together." He recounted his journey starting from a workshop electrician in 2004, gradually transforming into the Business Unit General Manager leading the chopped strand project. "Being rooted in the grassroots, embracing change, driven by responsibility, and achieving team win-wins" were his growth tenets, while "once the arrow is shot, there's no turning back; no matter how difficult, find resources, make improvements, and persist to the end" was his choice when facing challenges.
This experience allowed the attending students to genuinely feel that lean is never just cold tools, but a path that accompanies personal growth.
Growing Through Responsibility, Transcending Through Lean
Ms. Qiu Guilan, Vice Chairwoman of Huayuan New Materials, serving as a facilitator, conveyed key insights in her summary: managers cannot do without management accounting skills, and finance personnel lacking a management mindset can hardly serve as core helpers. She stated plainly that if management cannot achieve a 10% profit margin, it is not considered qualified. To meet this standard, one must closely adhere to the essence of management accounting – compressing process cycles, reducing waste, and increasing turnover rates – to achieve multiplied cash flow and a virtuous cycle of operations. Simultaneously, she mentioned that a General Manager must be responsible to investors, the team, and customers. This sense of responsibility towards multiple parties, seemingly a heavy burden, is actually a catalyst for accelerated growth.
This "Management Accounting" lesson deeply integrated lean thinking with management accounting, revealing that the essence of business management is not merely pursuing profit, but also managing time and cash flow. From formula analysis to waste reduction, from mindset shifts to talent growth, each step points to the same core – using management accounting to translate management objectives into daily concrete actions. When data becomes the language and improvement becomes the path, lean is no longer just a set of cold tools, but a living force that helps enterprises navigate cycles and achieve sustained profitability, guiding every manager to transform from a "bookkeeper" into a true "manager."
