Single Minute Exchange of Die (SMED)

Single Minute Exchange of Die (abbreviated SMED) is one of the many lean manufacturing techniques designed to speed up product switching processes and decrease wasteful manufacturing practices. SMED is essential in increasing productivity while reducing waste levels in manufacturing operations.

Shigeo Shingo, an internationally acclaimed industrial engineer and expert on the Toyota Production System, devised SMED. His efforts reduced changeover time for transfer stamping machines from hours to 180 seconds, saving both time and resources for production lines alike.

What is SMED?

SMED is an innovative process that significantly shortens changeover times between production runs. This is achieved by categorizing changeover elements as internal or external to machine operation time and then adapting or simplifying them during normal machine operations - thus significantly decreasing changeover times, often down to mere minutes!

An SMED project can lead to substantial savings for any company. For instance, an action figure manufacturer selling them at $20 each could lose one sale every 60 seconds as they switch from mold to mold; with proper planning and execution, an SMED project may reduce this to 10 or fewer seconds!

An SMED pit crew can serve as an analogy for SMED, with process setups and changes representative of pit stops. Pit crews employ various strategies to streamline their work - prepositioning all tools before beginning an actual pit stop, using standard attachment points and methods, etc. Their aim should be to reduce tire swap times from 15 minutes to sub-10 seconds as quickly as possible.

SMED projects at manufacturing plants may involve switching products, moving between dies, modifying jigs, gauges, materials, and more to modify processes or modify equipment while it runs or shuts down; some steps may even need to be completed when the machine shuts down - SMED projects look at ways of streamlining or eliminating these steps to reduce changeover times from hours or days down to minutes (or single digits).

Once a baseline for your changeover process has been established, elements that can be completed while the machine runs are prioritized. Internal setup processes that remain are examined for opportunities for optimization and simplification, such as eliminating motion, waiting, adjustments, creating parallel operations, or standardizing hardware.

SMED can significantly decrease manufacturing costs by streamlining processes and reducing changeover times, improving OEE, increasing machine startup rates, and helping smaller lot sizes meet customer demand faster while reducing WIP and inventory levels.

What are the benefits of SMED?

SMED (short for "Simple Manufacturing Equipment Changeover") is an equipment changeover process developed in the 1950s by industrial engineer Shigeo Shingo to assist manufacturing companies in reducing inventory levels and boosting production efficiency. Lean practitioners use SMED in virtually every setting, from factories and fast food restaurants to offices.

SMED (Source for Manufacturing Excellence and Delivery) aims to eliminate non-value-adding procedures and streamline those remaining so teams can focus on only those critical steps needed for production efficiency and reduce waste while improving employee morale.

Initial die exchange processes were called Quick Die Change; however, Shingo later changed it to Single Minute Exchange of Die to reflect his goal of shortening setup times as much as possible. Unfortunately, "single minute" can be misleading since changeover procedures do not need to take only a minute; single-digit minutes (less than 10) would be more suitable.

SMED can save time, but its other advantages also include:

Reduced manufacturing costs. Shorter changeover times lead to reduced downtime periods and lower material, labor, and energy costs. Increased flexibility. Shorter changeover times give manufacturers more ability to produce just enough products at any time while decreasing inventory carrying costs and carrying costs.

Increased Quality. Rapid changeover times allow for quicker product switches with increased frequency, meaning higher levels of consistency in quality.

Implementing the SMED process can be difficult and complex, impacting every aspect of business operations. Training your team on new procedures to explain why they will increase efficiency is crucial to ensuring the transition runs smoothly; also, developing standard work instructions helps ensure everyone knows exactly what needs to be completed and when.

Last but not least is to reduce unnecessary motion by organizing storage. Hence, it is easier for team members to find what they need quickly, using point-of-use storage where appropriate and clearly labeling equipment settings. This will also help mitigate human error during context-switching processes.

How can SMED be implemented?

Once your team is prepared to implement SMED, they must become organized. Create a list of all the elements involved in changeover processes and prioritize which can be completed while running while others must wait offline; this can speed up transitioning to single-digit minute setup times as quickly as possible. Also, consider whether any elements can be done simultaneously, such as tool prep while another part is produced; similar to how NASCAR pit crews operate, this can streamline processes further while using easily accessible standard tools can simplify processes further.

Once you have documented all of the internal elements, the next step should be identifying waste - both motion-related and time-based. To do this, simplify procedures, remove steps, and eliminate interactions that are no longer needed; equipment modification may also be required; designing highly portable machines reduces interface requirements while modular components enable moving them quickly between production lines.

Finally, it's essential to establish an initial changeover time baseline. This will enable a comparison of SMED implementation results against those from other companies that have already adopted the method. It should also recognize any Hawthorne Effect that might help your changeover times improve simply through watching and learning from the process itself.

SMED can be applied effectively in factories that manufacture action figures for children, which sell for about $20 each. The manufacturer can produce one every 60 seconds, so each time they switch molds, they lose out on sales worth $20.

To reduce these costs, the company started employing SMED strategies, such as switching from manual mold changes to one-touch systems for mold changes and cutting preparation time down from hours to minutes; lean manufacturing practices allowed them to achieve just-in-time production goals and cut inventory levels significantly.

What are the challenges of SMED?

SMED strives to reduce the time needed to change equipment from one product to another by identifying and eliminating unnecessary steps from its process and changing internal setup elements into external ones.

Industrial engineers have long understood the need to shorten changeover times. Shigeo Shingo, an engineer who worked at Toyota, developed the SMED system in the 1970s; quickly becoming popular, its usage has resulted in documented reductions of changeover time averaging 94%.

SMED can be invaluable for shortening changeover times, but companies must remember that it will only solve some of their production woes. To maximize its use and reap maximum returns from SMED, companies should focus on optimizing human and machine processes as part of a comprehensive approach to improvement.

Human improvements can be accomplished through organization and preparation, while machine improvements may involve engineering or optimization. Examples of human improvements would be creating standard work instructions, placing tools near the changeover area for easy access, labeling equipment settings, and eliminating wasteful motion.

Once a company has identified areas to improve, it must devise a plan for implementing SMED. This may involve assigning a project leader, holding brainstorming sessions, and training employees on how the new process works. Furthermore, they should set a timeline for reaching their desired results.

An unfortunate hazard of SMED processes is their tendency to prioritize speed over quality, leading to rushed or incomplete changeovers that compromise productivity and increase the risk of defects. Furthermore, it should be remembered that any successful implementation will still involve some downtime - even if only for minutes at a time.

Implementing SMED requires considering that learning its processes may take some time for teams, mainly if changes to production are significant. To combat this, new employees should receive training on SMED before beginning production work; this will give them a deeper understanding of its workings and facilitate more straightforward adaptation.

Eight Pillars of Total Productive Maintenance

Total Productive Maintenance (TPM), in contrast with reactive maintenance, which waits until equipment breaks before taking action, takes preventative steps to boost machine performance and prevent slowdowns, defects, or speed losses. TPM strives to maximize machine utilization while decreasing delays, imperfections, or speed losses.

TPM utilizes lean manufacturing and 5S principles to organize and standardize facility procedures while framing maintenance as an integral element of overall equipment effectiveness (OEE).

Identifying Problems

Total Productive Maintenance (TPM) is a lean manufacturing philosophy that seeks to achieve near-perfect production without small stops, breakdowns, defects, or accidents. TPM involves all facility employees, from floor plant technicians to senior facility managers, working collaboratively to improve equipment availability and quality while using preventive maintenance techniques and featuring eight pillars.

Step one in any TPM program should be to identify issues that could impede production and take corrective actions. This involves an in-depth evaluation of the current production process, including a review of downtime losses, defect losses, and speed losses and identifying the root causes of these losses.

Problem-solving techniques combined with automated tools like condition monitoring can be used to achieve this objective. Condition monitoring provides real-time information on equipment status, allowing facilities to quickly pinpoint its root cause (such as excessive wear and tear ) to prioritize future actions and limit downtime.

Preventative maintenance checklists can also help identify problems by increasing employee awareness of what must be done and when. They also reduce the time and effort needed for routine tasks performed by maintenance personnel.

Problems that impede production can often be easily identifiable, for example, when a machine stops functioning due to sensor or power surge issues. Other issues, however, may be more challenging to detect or pinpoint, such as improper operator training, lack of organization in the workplace, and inconsistent inspection schedules.

TPM provides an effective solution to these issues by shifting responsibility for basic equipment upkeep to its primary users: machine operators. This enables them to perform autonomous maintenance like cleaning and safety checks without needing assistance from technicians - potentially cutting production losses significantly while improving overall equipment effectiveness (OEE).

TPM stresses the significance of streamlining administrative functions to eliminate wasteful organizational practices, such as expediting order processing, purchasing, and scheduling, to avoid delays in finding necessary parts or materials for production.

Preventative Maintenance

Total Productive Maintenance is a framework for optimizing facility maintenance to eliminate resource waste, employee accidents, product defects, and unplanned downtime. However, its success relies upon effective maintenance practices used to support it; an excellent CMMS makes identifying issues simple while tracking maintenance and repair costs, helping avoid breakdowns or unexpected repairs that might otherwise cost more than anticipated.

Step one of implementing Total Productive Maintenance is setting goals for your most crucial assets and equipment using quantifiable and measurable metrics. For instance, if a critical piece of machinery consistently breaks down or produces products below quality standards, set an annual goal to reach zero production losses; this will motivate your employees for continuous improvements and help get your TPM program off the ground.

Once your targets have been set, the next step should be creating a preventative maintenance schedule for your most valuable equipment. Begin with the frequency the manufacturer recommends, adjusting as necessary to avoid over or under-maintain them. In addition, create a preventative maintenance checklist to keep track of team tasks and ensure all required tasks are accomplished; mandatory charges should be addressed immediately, while non-mandatory ones may be completed without risking equipment failure or productivity losses.

After establishing a preventive maintenance routine, training employees is critical for increasing autonomy and decreasing over-reliance on reactive maintenance. A CMMS can assist this effort by offering quick access to maintenance logs and controlling inventory. Hence, you always have spares and centralizing information about each asset (OEM recommendations, fault patterns, inspection procedures).

Once your employees are trained, they should begin identifying problems and taking measures to address them using the practice of Kaizen (continuous improvement to optimize processes and eliminate waste). As you implement changes, you must measure progress to know which areas need further improvement while tracking what changes work well and which require additional work from your team.

Restoring Equipment to Prime Operating Condition

Each piece of equipment must be in top operating condition to maximize performance. This can be accomplished through adhering to TPM principles to eliminate waste in manufacturing. TPM helps eliminate unscheduled downtime, scrap, rework, and product quality issues that adversely impact equipment failure that require costly repairs or replacements.

TPM requires all employees to assume some responsibility for equipment maintenance management to improve equipment availability, allowing everyday users to take on essential upkeep duties like cleaning, lubrication, and inspection while freeing up facility and maintenance staff to focus on more critical tasks. This allows people with intimate knowledge of equipment like cleaning machines to take ownership of basic upkeep such as cleaning, lubricating, and inspecting them themselves while freeing facility and maintenance teams up for more pressing duties.

Step two of TPM involves identifying and addressing significant losses in production processes. A cross-functional team of employees should gather to conduct root cause analysis on all available data sets to pinpoint areas that should be considered. Once problem areas have been identified, an action plan can be developed to address them.

Training operators on identifying and fixing issues quickly and devising simple preventative maintenance procedures they can promptly implement can also be very beneficial. Visuals that track equipment health and performance, such as color-coded charts showing when lubrication should occur, may help identify any under or over-lubrication problems; using visuals to spot potential problems early can improve OEE while reducing downtime.

Implementing Total Productive Maintenance can be challenging, yet can yield significant improvements to manufacturing processes. By eliminating six big losses in production, TPM can increase profitability through lower operational costs and improved product quality while raising worker morale by placing maintenance as part of a company's core value system.

Measurement

An effective total productive maintenance implementation relies on robust measurement and data collection techniques. This involves collecting and analyzing production and maintenance data to assess each piece of equipment's status and identify any critical problems while simultaneously identifying significant losses - the six leading causes of failure in industrial environments that must be addressed through root cause analysis of OEE data to pinpoint its causes and solve any related issues.

TPM seeks to shift responsibility for equipment maintenance away from an independent maintenance department and onto all plant personnel by assigning tasks typically reserved for dedicated crews, such as cleaning and lubricating equipment, performing regular safety checks, and identifying signs of trouble early. This approach blurs the distinction between manufacturing and maintenance by investing every employee in its success - making everyone part of an organization's machinery's success!

TPM may seem challenging to implement in a factory environment, but companies that commit themselves and take the necessary time and care will see results over time. TPM can reduce equipment stoppage costs while increasing productivity, resulting in greater profits for your company.

TPM calls for developing a culture of continuous improvement, or Kaizen. This means gathering small groups of workers to brainstorm ways to enhance equipment and processes within their facility, including finding early adopters to lead this initiative and spread knowledge throughout.

Though TPM may seem ideal for production facilities, its applications extend to offices and administrative functions. By applying TPM tools in these areas, businesses will find that waste reduction increases along with organizational efficiency in procurement, order processing, scheduling, and more consistent production processes that ultimately boost worker morale and quality of life.

Pros of Total Productive Maintenance (TPM)

• Reduced Downtime: TPM aims to minimize equipment downtime, increasing productivity and efficiency.
• Improved Quality: By maintaining equipment in optimal condition, TPM helps produce high-quality products.

• Limited to Manufacturing: TPM is most effective in manufacturing settings and may not apply to all types of businesses.
• Requires Cultural Shift: Successful TPM implementation may require a change in organizational culture, which can be challenging.
• Risk of Inconsistency: Withorts can become inconsistent over time without proper train consistent-through.
• High Expectations: Promising significant improvements can lead to high expectations, and failure to meet them can be demotivating.

The Four Lean Principles That Transform Service Delivery

Lean Principles are a Scrum project management methodology that promotes waste elimination. While initially developed for manufacturing purposes, these principles have since found widespread application within service delivery.

Lean begins by identifying value. Any process or activity that doesn't add actual worth should be seen as waste and eliminated from operations.

Identifying Value

The first step of lean is identifying value, ensuring that all stages in the workflow are needed, and providing value to customers. This can be accomplished by performing a value stream mapping exercise that monitors every step from beginning to the end of your product’s journey. This ensures all processes are streamlined and eliminates unnecessary ones, saving time (speeding up your workflow), energy, and resources.

A key aspect of identifying value is learning from your past mistakes. This can be done by creating a system that encourages experimentation and analysis of your current processes. This enables you to identify bottlenecks blocking workflow and implement a solution to reduce these barriers. For example, an organization's standard problem is storing too much inventory, which increases costs and decreases productivity. Using the just-in-time method of production, like Dell did when it revolutionized the computer industry, minimizes waste by only producing what is needed at each production stage.

Another source of waste is excessive movement. This can be caused by people or driven machines moving around unnecessarily. Implementing lean tools such as Kanban can help streamline these processes. This removes the need for excess inventory, which can increase efficiency and productivity.

While lean practices have their roots in manufacturing, they can be applied in any industry. From healthcare to software development, lean principles can reduce waste and inefficiencies that cost projects time and money. Poor project management is self-reinforcing and allows teams to create a continuous process improvement cycle through iterative experiments, customer feedback, and knowledge sharing amongst team members. To start your Lean journey, consider enrolling in a Green Belt certification training course to understand the methodologies involved.

Mapping the Value Stream

As part of the Lean process, mapping your value stream is one of the first vital steps. It provides a structure to analyze how products and services reach customers cost-effectively while helping you identify waste.

At this stage, teams should carefully consider all stakeholders and the value they expect from the value stream to better focus their analysis and improvement efforts around these needs. They should also create a charter to guide their mapping effort, outlining desired future state and expected improvements such as decreased lead/cycle time/handoffs between departments/wait times, etc.

An essential concept in this stage is flow, or "rate of movement," which describes how quickly items pass through the value stream. A good way of visualizing this concept is a timeline or "time ladder," which shows the time it takes from the starting point (first fence post) through the development cycle to completion (last fence post).

At this step, the objective is to expedite all actions that contribute to product or service value as quickly as possible, emphasizing eliminating those that do not contribute directly to customer value. Although this can be challenging at times, reaping significant benefits such as shorter lead and cycle time, increased productivity, cost savings, customer satisfaction rises, and faster cycle time; 5S, poka-yoke, kaizen balanced workflow SMED inventory reduction are among several methods of implementation which may assist.

Flow

Flow is at the core of any Lean implementation; its aim should be achieved as efficiently and painlessly as possible. When operations move through with no delays or waste being created or reduced as one unit to deliver value to customers - an effect many senseis I worked with revered; some fancy terms for it include Continuous Flow, One Piece Flow, or Single Piece Flow.

The initial step should be mapping your entire value stream to facilitate flow. A Value Stream Map (VSM) shows this exact flow. Once complete, implement a pull system by decreasing inventory or work-in-progress and connecting as many value-adding steps as possible.

By streamlining production processes, companies can reduce the steps required to produce finished goods, shorten cycle times, and increase throughput. They also make it easier for teams to respond more efficiently to customer needs, so communication with customers, listening to feedback, and making changes accordingly are essential for business growth.

Implementing a pull system has several critical advantages over its traditional counterparts in Lean manufacturing, such as eliminating overproduction and inventory waste. By restricting production to what's needed, production becomes less likely to contain defects - this can be accomplished through Just-In-Time delivery of raw materials (JIT), designing processes to minimize defect risks (Poka-Yoke and Jidoka), or standardized work. Hence, all workers follow identical methods (Standardized Work).

As you continue implementing lean principles, you continually refine your operations. This will accelerate customer value delivery and allow teams to identify additional means of providing their clients even more excellent products and services.

Pull

The fourth lean principle involves employing a pull system to reduce waste. This ensures that only goods needed by actual customer demand are produced - thus eliminating waste and keeping production processes running efficiently.

Pull systems help companies decrease the inventory they keep on hand, which helps cut storage costs and other related expenses. However, implementing such a process is complex; it requires communication among departments and significant time and effort in setting up systems. Once companies have implemented three lean principles, they're in an ideal position to implement such strategies and establish pull systems.

One of the biggest mistakes a company can make when trying to implement a pull system is failing to understand what makes a product or service valuable for their customer base. Most people tend to assume it's all down to them, but listening and understanding their needs can help avoid making this errorful assumption.

Pacing production to match customer demand (Takt Time) can lead to issues when companies need more capacity. To prevent this issue, buffers must be reduced or removed entirely between production steps.

At its core, lean manufacturing demands continuous improvement - companies must constantly search for ways to optimize production processes and eliminate wasteful practices to stay slim. Continuous improvement is integral to lean manufacturing and can boost productivity levels across an organization.

Perfection

Root Cause Analysis (RCA), one of the central tools of lean methodology, helps ensure every process operates at peak performance. By pinpointing specific issues affecting your process and offering systematic approaches for improving, solving, or taking control over them - root Cause Analysis also supports continuous learning and improvement as a cornerstone principle of lean.

Whether you own an online store or construction firm, ineffective processes can drain resources and hinder optimal performance. Employing lean tools like RCA and poor project management can save time and money while increasing productivity for excellent customer value creation.

Implementing lean principles is an ongoing journey that requires team members to adapt their culture to eliminate and prevent waste. Unfortunately, top management often resists this cultural transformation, thus hindering its successful implementation in an organization.

Failure of many organizations to increase efficiency through lean tools has contributed to their ineffective implementation, and lack of knowledge surrounding lean methodologies is a contributing factor. Thus, understanding their workings is essential before adopting them in your workplace.

Lean project management tools, such as Kanban boards and sprints, can increase productivity at your company by eliminating obstacles that hinder its journey to providing value to its customers. However, waste must also be minimized; to do this effectively, you should implement four of Lean's five principles - identifying value, mapping the value stream, creating flow, and adopting a pull system. The fifth principle, "Pursue perfection," makes skinny thinking part of your organizational culture.

Six Sigma

Six Sigma employs statistical tools and techniques to enhance processes for greater accuracy. Teams equipped with special training carry out this methodical improvement strategy.

Friedrich Gauss' work established the bell curve that forms one of the fundamental pillars of Six Sigma theory.

Define

Six Sigma is a methodology to reduce defects that could cause products or services to fail and reduces output variations to as few as 3.4 defects per million opportunities (DPMO). Six Sigma's collection of tools for process improvement is widely utilized by businesses worldwide to increase profits and customer satisfaction - it combines two concepts from the 1920s: Total Quality Management and Zero Defects.

Six Sigma can help improve productivity and efficiency in any business process - from manufacturing to data analysis - including statistical methods like Design of Experiments and Taguchi for continuous improvement. It can even contribute to increased profits! It can improve both productivity and efficiency. Processes with efficient processes will have fewer defects and produce results more quickly, resulting in greater profits for the business. With great success, Six Sigma can be applied across any field, from manufacturing to data analysis.

Implementing Six Sigma involves altering how an organization conducts business, so success depends on having upper management support and staff understanding its motivation to change. A training program should be put in place for employees of all levels to assist with this transformation - White Belts receive an introduction to process improvement theory and terminology, while Yellow Belts may take an active part in Six Sigma projects; Black Belts lead the charge on individual projects while Master Black Belts oversee larger-scale Six Sigma strategies.

DMAIC improvement begins by identifying the current state and any problems within their approach, then identifying root causes before creating solutions to address them. After installing their answer, they test it thoroughly to make sure it works and make changes if necessary before controlling it to maintain improvements made.

Measure

Six Sigma is an approach to increasing internal processes' efficiency by eliminating waste. This saves time and money while yielding improved results; whether your manufacturing company needs to reduce defective products or you're trying to boost donor satisfaction - Six Sigma can assist.

The measure is the second phase of the DMAIC process and assesses current project or process performance through surveys, interviews, or observation. Your team can also use data from previous projects as a benchmark performance indicator.

Six Sigma teams must further define and define measures they will collect data on at this stage. This may involve measuring customer satisfaction levels or analyzing average call handling times; understanding these measurements and their objectives will help ensure accurate and valid data collection.

Six Sigma teams must conduct an MSA, create a data collection plan, and select their metrics. This requires coordination among departments as well as using appropriate software programs; an experienced Six Sigma Green Belt should be able to handle this step effectively as it involves Gage R&R concepts covered during training programs.

Six Sigma in healthcare has proven invaluable for numerous reasons. It helps reduce medical errors and service variation, which increases patient safety while improving hospital and outpatient organizational effectiveness. Furthermore, Six Sigma supports interprofessional collaboration among nurses, allied health professionals, and clinicians for more innovative solutions that improve patient outcomes.

Analyze

Six Sigma strives to give a clear view of a process by gathering and analyzing data, which is done during the Analyze phase of Six Sigma. This can help identify areas for improvement and any process mapping, root cause analysis, or statistical analyses that might be utilized during this process.

At this stage, a team analyzes every element of a process in search of the root causes of its defects and defects that must be fixed during subsequent DMAIC steps. They aim to pinpoint these problems so Six Sigma specialists can resolve them during the following DMAIC steps - this may prove challenging but essential in increasing efficiency within your company processes. Analysis tools used at this stage include detailed process maps, Pareto charts, and various statistical analysis methods such as ANOVA or regression analysis.

The analysis phase is an integral component of Six Sigma because it allows teams to assess how a problem impacts all areas of operation. An example would be overproduction in manufacturing plants when factories produce more than is desired or needed. Overproduction often leads to excess inventory, costly storage fees, and additional forms of waste such as rework or scrap, thus impacting company bottom lines negatively. Analysis helps teams understand this impact more fully and take appropriate actions.

At this stage, it is necessary to form theories regarding the cause of problems using subjective and observational tools like Fishbone diagrams and Process Maps. Next, using mathematical rigor through means like ANOVA and Chi-Square statistics tests these theories until they find those responsible.

Improve

Six Sigma is an approach to quality management that integrates proven quality principles with data-driven processes to help organizations eliminate waste and improve outcomes across various industries and organizational structures. Training for Six Sigma courses ranges from yellow to black for individuals and organizations.

Six Sigma provides teams with an iterative process with clearly outlined steps, which enables them to effectively manage projects and track progress using the DMAIC (Determine, Measure, Analyze, Improve, and Control) methodology. Every step builds upon itself to avoid making changes simply for its own sake or addressing root causes that do not directly address these changes.

Step one of the Six Sigma DMAIC methodology's Improve stage involves identifying potential solutions. Here comes the Five Whys information gathering technique, along with tools like affinity diagrams and multi-voting to generate and select possible solutions; then, using must and want criteria, the team determines which will most reliably fix the issue.

Once a solution has been identified, the team can implement it. Ideally, this should take place for observers to assess its impact before being re-evaluated to see whether it has been successful. Here, the team should identify best practices while noting areas needing further improvement.

Six Sigma may only apply to for-profit companies, but nonprofits can also use its principles to enhance employee satisfaction or increase donations per appeal. Six Sigma has even been implemented within sports to assist athletes in reaching their goals through analytics and tailored training plans.

Control

Control Phase. The goal of the Control Phase is to make process improvements part of daily operations and to establish them permanently. In this phase, teams implement control plans, monitor new processes for compliance with Six Sigma parameters, and train staff members who will now execute them.

Six Sigma originated in manufacturing but is applicable across numerous business settings. Healthcare organizations, in particular, can benefit significantly from incorporating Six Sigma practices, which help reduce medical errors and increase patient safety. As a data-driven quality strategy focused on customer satisfaction, Six Sigma uses the DMAIC method - defined, measured, analyzed, improved, and controlled.

A DMAIC project begins by selecting a process needing improvement, then the team defines its issues, identifies opportunities for change, and establishes a target quality level. After measuring current process performance against its previous ones and creating a baseline to compare future ones against, DMAIC projects analyze measurement results by pinpointing any root causes or creating action plans to address each issue identified during measurement.

Implementations. After making changes and testing them for effectiveness, the team implements and tests improvements and monitors the new process to prevent any reversion to prior performance and ensure high-level performance is sustained; here is where a well-developed Six Sigma control plan comes into play. Finally, after updating lessons learned and getting management's approval to officially close the project. However, if the project yields significant dollar savings, the team must document these savings amounts and get the financial controller's agreement before moving on to other phases of improvement work.
