What is lean thinking and practice?

A Brief History of Lean

In the realm of manufacturing, the roots of meticulous process thinking trace back to the Arsenal in Venice in the 1450s. However, it was Henry Ford who, in 1913 at Highland Park, MI, truly revolutionized production. Marrying consistently interchangeable parts with standard work and conveyance, Ford introduced what he termed as "flow production." The iconic moving assembly line captured the public's imagination, but the breakthroughs extended far beyond mere spectacle.

Ford strategically organized fabrication steps, utilizing special-purpose machines and go/no-go gauges to craft and assemble vehicle components seamlessly. This departure from the American System's general-purpose machines marked a revolutionary shift. Unlike the traditional approach of fitting parts through subassembly and final assembly, Ford's system delivered perfectly fitting components directly to the line side.

However, Ford's triumph in flow production faced a limitation: lack of variety. The Model T, though efficient, offered minimal choices, confining customers to a single specification. Ford's machines predominantly worked on a single part number, with almost no changeovers.

The pursuit of variety led other automakers to explore diverse models and options, albeit at the cost of longer times. Larger, faster machines filled fabrication shops, increasing costs per process step and escalating inventories. The need for sophisticated information management systems, like Materials Requirements Planning (MRP), became evident.

In the 1930s and post-World War II, visionaries like Kiichiro Toyoda and Taiichi Ohno at Toyota revisited Ford's ideas. Their reflections culminated in the Toyota Production System, a paradigm shift focusing on product flow through the entire process. Toyota emphasized right-sizing machines, self-monitoring for quality, quick setups for small volumes, and efficient communication between process steps. This innovation aimed at achieving low cost, high variety, high quality, and rapid throughput.

The principles of lean thinking, as detailed in "The Machine That Changed the World" (1990) and further distilled in "Lean Thinking" (1996), can be these lean principles even further to five.

1. Specify the value desired by the customer.

2. Identify the value stream for each product and eliminate wasted steps.

3. Ensure continuous flow through value-added steps.

4. Introduce pull between steps where continuous flow is impossible.

5. Manage toward perfection, reducing the number of steps, time, and information needed.

Today, Toyota stands as a global exemplar of lean enterprise, poised to become the largest automaker worldwide. The principles of lean thinking have extended beyond manufacturing, influencing sectors such as logistics, healthcare, services, and even government. As lean thinking continues to permeate every corner of the globe, its impact on diverse industries is only beginning to unfold. The journey of lean thinking is far from over, with leaders across sectors adapting its tools and principles to drive efficiency and excellence.

What is Lean?

• Embracing Lean involves a mindset geared towards generating essential value while optimizing resources and minimizing waste.
• The essence of Lean extends beyond mere thought, manifesting as a continuous practice rooted in experimentation.
• The ultimate goal: attaining flawless value creation with absolute waste reduction. In essence, Lean thinking and practice go hand in hand, creating a symbiotic relationship.

Customer-centricity forms the bedrock of Lean thinking. Initiating with a fundamental question — What does the customer value? Or, in a more actionable context, what problem requires the customer's resolution?

The practice of Lean commences with the tasks at hand — the actions directly and indirectly shaping value for the customer — and the individuals carrying out those tasks. Through a continuous cycle of experimentation, both workers and managers engage in innovative approaches, fostering better quality, enhanced flow, reduced time and effort, and lower costs in their physical or knowledge-oriented work. Consequently, an organization embodying Lean practice exhibits remarkable adaptability within its dynamic environment. This adaptability stems from the systematic and ongoing learning cultivated through the amalgamation of Lean thinking and practice.

A Lean enterprise is meticulously structured to uphold a constant awareness of the customer and their context. This involves:

Specifying value and seeking continual improvements through product and process development.

Ensuring a streamlined journey from order through production to delivery during fulfillment.

Addressing the complete lifecycle of the product or service, from delivery through maintenance and upgrades to recycling.

The Lean Transformation Framework

• Decoding the Lean Transformation Framework

At the heart of Lean methodologies lies the Lean Transformation Framework — a systematic and proven approach designed to tackle challenges spanning the entire enterprise spectrum. Whether steering an established organization or navigating the startup landscape, the Framework serves as a versatile tool to address issues at every level, from strategic decision-making to day-to-day operations. It centers around five pivotal questions, offering guidance on purpose, process, and people, thereby facilitating solutions that align with these core elements.

Drawing from decades of hands-on lean practice, the Lean Transformation Framework evolved through practical insights. The framework encourages practitioners to enhance a specific aspect of their work processes, recognizing that improvement is the key to understanding lean transformation. Embedded within the framework are five essential questions that Lean Enterprise Institute (LEI) integrated for effective problem-solving:

1. What is the value-driven purpose, or the problem to solve?
2. What is the work required to address the problem?
3. What capabilities are necessary to perform the work and solve the problem?
4. What management system, including operating procedures and leadership behaviors, is needed?
5. What fundamental thinking, encompassing mindsets and assumptions, is essential for the organization as a purpose-driven socio-technical system?

These questions exhibit a fractal nature, applicable at both macro and micro-enterprise levels, ensuring usability for individuals across all organizational tiers, from CEOs to frontline supervisors.

For effective utilization of the Framework, a comprehensive understanding of how each question and its corresponding answer interrelate is imperative. This synergy ensures the maintenance of momentum towards achieving a successful transformation.
