“Quick Response Manufacturing” (QRM) by Rajan Suri presents a comprehensive strategy designed to reduce lead times throughout the entirety of a manufacturing operation. Published in 1998, the book focuses on reducing manufacturing and office operations lead times to achieve better productivity, lower costs, and improved competitiveness. Suri introduces QRM as a holistic approach that encompasses the entire organization rather than isolated departments. Below is a detailed summary that highlights key points and practical actions derived from the book, organized systematically.

QRM is grounded in the notion that reducing lead times across all functions of a company can lead to significant benefits in terms of rapid delivery, flexibility, and cost reduction. Unlike traditional efficiency-focused manufacturing methodologies, QRM prioritizes time as the main factor of competitiveness.

Action: Assess and document current lead times across all departments—manufacturing, engineering, and administration. Establish benchmarks and set goals for lead time reduction.

Suri introduces MCT, which measures the time from an order being created until the first part is delivered. MCT helps teams focus on areas that have significant time delays and drives the strategic focus on time reduction.

Action: Calculate the MCT for various product lines in your company. Use this metric to identify bottlenecks and prioritize areas for process improvements.

Suri emphasizes the importance of restructuring traditional functional layouts into QRM Cells—dedicated cross-functional teams that work on a complete product or family of products. These cells help minimize hand-offs and waiting times.

Example: Convergent Technology, a case study in the book, transitioned to QRM cells and experienced a lead time reduction from weeks to days by integrating design, manufacturing, and testing departments.

Action: Create cross-functional QRM cells focused on specific product lines. Gradually break down traditional department siloes to enhance coordination and efficiency.

Traditional management often views system utilization as maximizing machine or worker usage. Suri argues that this approach inadvertently increases lead times due to overloading resources and creating queues. Instead, QRM promotes lower utilization rates to increase flexibility and reduce lead times.

Action: Conduct a utilization study. Aim to operate critical resources at 70-80% capacity to ensure flexibility and rapid response capabilities.

To manage workflows and reduce lead times, Suri introduces the POLCA system—a visual production control system tailored for high-mix, low-volume environments. It ensures materials move only when the subsequent cell is ready, avoiding traditional scheduling pitfalls.

Example: Company X implemented POLCA, transitioning from push to pull production, resulting in a 50% reduction in lead times for custom orders.

Action: Implement POLCA in your production cells. Train employees on the system and progressively replace traditional scheduling methods.

Time spent in office processes (quoting, engineering changes, etc.) significantly contributes to lead times. Suri promotes applying QRM principles to office operations, known as Quick Response Office Cells (Q-ROCs).

Example: A manufacturing company restructured its quoting process into a Q-ROC, reducing quote turnaround time from two weeks to two days.

Action: Analyze office workflows and form Q-ROCs to handle tasks such as order processing and quotations. Streamline communication and reduce queue times.

Rather than a broad-brush approach, Suri advises companies to target specific market segments where lead time reduction can offer a competitive edge. By focusing resources on these segments, companies can deliver greater value.

Example: A machinery manufacturer focused on the specialized medical equipment market. By emphasizing QRM, they gained market share by offering the fastest delivery times.

Action: Identify high-potential market segments where reduced lead times can offer a competitive advantage. Redirect marketing and sales efforts towards these segments.

Adoption of QRM often meets resistance from employees accustomed to traditional methods. Suri suggests planned and participatory change management strategies.

Action: Develop a change management plan that includes employee education, involvement, and regular feedback sessions. Highlight successful case studies and quick wins.

Several case studies within the book illustrate concrete benefits. For instance, John Deere Engine Works applied QRM principles and observed a lead time reduction from 75 days to 14 days.

Action: Document and publish internal success stories. Use these to motivate and guide other departments in adopting QRM practices.

“Quick Response Manufacturing” by Rajan Suri is a paradigm-shifting book that presents a robust framework focused on the strategic reduction of lead times. Through detailed explanations, real-world examples, and actionable advice, Suri offers a companywide approach that can transform the efficiency and responsiveness of manufacturing operations. Implementing QRM involves a dedicated shift towards time-centric thinking, restructuring organizational workflows, and fostering a culture that values rapid response.

Final Action: Begin with an organizational audit focused on current lead times and inefficiencies. Develop a step-by-step QRM implementation plan, starting with pilot projects, and progressively expand these strategies across the company, while regularly measuring and reporting improvements in lead times and other success metrics.
