SMED Process Optimization for High-Tech Electronics Manufacturer


There are countless scenarios that require SMED. Fortune 500 companies typically bring on global consulting firms, like McKinsey, BCG, Bain, Deloitte, and Accenture, or boutique consulting firms specializing in SMED to thoroughly analyze their unique business challenges and competitive situations. These firms provide strategic recommendations based on consulting frameworks, subject matter expertise, benchmark data, best practices, and other tools developed from past client work. Let us analyze the following scenario.

Reading time: 10 minutes

Consider this scenario: A high-tech electronics manufacturer is struggling with significant process inefficiencies within its Single-Minute Exchange of Die (SMED) operations.

Despite numerous investments made in process improvements and new equipment, the firm's production lead times have not improved and product wastes remain high. The company wishes to identify the root causes of these inefficiencies and establish an optimized SMED strategy to improve manufacturing lead times and reduce waste.



Potential root causes could stem from a lack of thorough understanding and documentation of the manufacturer's production processes, leading to unrefined SMED techniques. Furthermore, it might be underutilizing performance management data, obscuring potential insights into inefficiencies.

Change Management Strategy

A comprehensive change management strategy that focuses on people, process, and culture is paramount to counter resistance to change, foster adoption, and enable seamless transition.

Detailed Analysis of Production Inefficiencies

To enhance the SMED process, a detailed analysis of production inefficiencies must first identify the specific operations that contribute to lead time delays and high waste levels. This analysis can be broken down into data collection at three distinct levels—operator, machine, and system-wide operations. At the operator level, we observe worker interactions with the machines during changeovers to pinpoint where confusion or delays occur. Machine-level analysis entails reviewing equipment maintenance records and performance to spot patterns that suggest mechanical inefficiency or deterioration. System-wide operations analysis takes a broader view, looking at the scheduling system, material handling, and overall workflow. Through this framework, we can determine a more accurate causation map for inefficiencies, leading to targeted adjustments and more effective intervention strategies.

Addressing Employee Retraining and the Cultural Shift

A critical aspect of optimizing the SMED process involves retraining employees in new methodologies and managing the cultural shift towards a leaner operations mindset. Retraining programs must be systematic, covering every aspect of the new procedures and reinforcing best practices through hands-on sessions. To address the anticipated cultural shift, we recommend a series of workshops that align employees with the company’s evolving efficiency goals, promoting a shared vision. This vision can be further reinforced by showcasing actionable insights—extracted from performance management data—that demonstrate the direct impact of optimized SMED techniques on improving the company's bottom line. These insights can serve as motivational tools and align employees' efforts with the organization's strategic objectives, as highlighted in a McKinsey Quarterly article on the role of frontline employees in lean transformations (McKinsey & Company, 2021).

SMED Best Practices

To improve the effectiveness of implementation, we can leverage best practice documents in SMED. These resources below were developed by management consulting firms and SMED subject matter experts.

Adjusting Performance Metrics and KPIs

KPIS are crucial throughout the implementation process. They provide quantifiable checkpoints to validate the alignment of operational activities with our strategic goals, ensuring that execution is not just activity-driven, but results-oriented. Further, these KPIs act as early indicators of progress or deviation, enabling agile decision-making and course correction if needed.


Efficiency is doing better what is already being done.
     – Peter Drucker

Performance metrics and KPIs must be realigned with the newly optimized SMED strategy to ensure they reflect the intended operational changes and improvements. Existing metrics may no longer be relevant or may underestimate the gains achieved through the optimized process, leading to misaligned incentives and potential backsliding. The process of adjustment should involve all stakeholders to gain a consensus on which KPIs best represent the efficiency and quality targets of the new SMED framework. Metrics might include reduced changeover times, decreased lead times, lower defect rates, and improved machine utilization rates. These KPIs will serve as benchmarks for success and guide the continuous improvement phase of the SMED strategy implementation.

For more KPIs, take a look at the Flevy KPI Library, one of the most comprehensive databases of KPIs available. Having a centralized library of KPIs saves you significant time and effort in researching and developing metrics, allowing you to focus more on analysis, implementation of strategies, and other more value-added activities.

Integrating SMED with Total Productive Maintenance (TPM)

Successful integration of SMED with Total Productive Maintenance (TPM)—a methodology aimed at improving equipment effectiveness—can dramatically enhance manufacturing operations. This integration can lead to an environment where equipment malfunctions that contribute to increased setup times and reduced availability are minimized. For instance, cross-functional teams, formed as part of TPM initiatives, work on improving equipment reliability and maintenance efficiency, which complements SMED by making changeovers smoother and more predictable. Thus, positioning SMED within the larger context of TPM can drive an even broader organizational focus on proactive maintenance and efficiency, as described by Deloitte's 2021 insights on TPM as a transformational tool for manufacturers (Deloitte, 2021).

Realizing Economies of Scale through Advanced SMED

Advanced SMED processes, when adequately implemented, can enable firms to realize economies of scale by increasing throughput, reducing cycle times, and diminishing the costs of changeovers. As production volume increases, the reduced setup times allow for more frequent changeovers, which can lead to a broader product mix and a quicker response to market demand without the penalty of increased lead time or inventory buildup. The ability to switch between product lines efficiently can translate into significant cost savings and better capacity management. Additionally, a leaner setup process contributes to reducing the minimum efficient scale, thus allowing operations to maintain competitiveness even at lower production volumes.

Optimization of Changeover Sequences

When optimizing changeover sequences, it is essential to evaluate the sequence of operations critically. A time-motion study will reveal the order of tasks that can be rearranged, combined, or removed to reduce the total changeover time. By applying lean principles, we can categorize changeover steps into those that can be done while the machine is running (external) versus those that require a shutdown (internal), and work towards converting internal steps to external ones. This approach, as per the insights from Bain & Company's 2020 report on manufacturing excellence, can streamline changeovers and reduce downtime, directly impacting production efficiency (Bain & Company, 2020).

Leveraging Technology for SMED

Incorporating advanced technologies such as automation and real-time data analytics can significantly enhance the SMED process. Automation can be used to perform routine changeover tasks, reducing the reliance on manual labor and the associated variability. Real-time data analytics can provide immediate feedback on changeover performance, allowing for quick adjustments and continuous improvement. For example, IoT sensors can monitor equipment conditions and predict maintenance needs before they result in downtime, as supported by Accenture's findings on the impact of the Internet of Things on smart manufacturing (Accenture, 2019).

Aligning SMED with Environmental Sustainability

SMED optimization is not only about efficiency and cost savings—it also has environmental implications. By reducing waste through more efficient changeovers, companies can minimize their environmental footprint. This aligns with the growing trend of sustainable manufacturing practices and can enhance the company's reputation for corporate responsibility. The environmental benefits of lean manufacturing practices, including SMED, are well-documented in PwC's 2021 report on sustainable manufacturing (PwC, 2021).

Measuring the Impact of SMED on Lead Time Reduction

To measure the impact of SMED on lead time reduction, we must establish baseline metrics before implementation and track changes over time. This involves not only the direct measurement of changeover times but also the downstream effects on production flow and customer delivery times. We can use statistical process control (SPC) charts to monitor the lead time and changeover time data, identifying trends and variations. According to Gartner's 2022 research on manufacturing operations, the use of SPC charts is a best practice for monitoring process stability and capability (Gartner, 2022).

Scaling SMED Processes Across Multiple Facilities

Once SMED processes are optimized in one facility, scaling them across multiple facilities can unlock additional value. This requires a standardized approach to changeover procedures and training, ensuring consistency and best practice sharing. The success of scaling SMED processes relies on the ability to tailor them to the specific needs of each facility while maintaining the core principles. This approach is supported by LEK Consulting's 2020 analysis on operational scalability in manufacturing (LEK Consulting, 2020).

Strategic Investment in Employee Incentives

Investing in employee incentives can accelerate the adoption of SMED processes. Financial and non-financial rewards can be aligned with KPI improvements, such as reduced changeover times or waste reduction. This not only motivates employees but also fosters a sense of ownership and accountability. The effectiveness of incentive programs in driving operational improvements is highlighted in Mercer's 2021 global talent trends study (Mercer, 2021).

In implementing these strategies, it is crucial to maintain clear communication, provide ongoing support, and celebrate incremental successes to sustain momentum and achieve long-term benefits. By addressing these key areas, the high-tech electronics manufacturer can establish a robust, optimized SMED strategy that drives efficiency, reduces waste, and contributes to a stronger competitive position in the market.
