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.

Just-In-Time Inventory Management

Just-In-Time was developed in post-World War II Japan as a production model that reduces inventory costs while meeting customer demands in real-time. Accurate demand forecasting is vital to this method of manufacturing and delivery.

JIT relies on local sourcing, which may be more expensive. Furthermore, it requires effective communication among departments and centralized data systems.

Inventory Management

Just-in-time inventory management systems reduce waste and free up valuable space. At the same time, simultaneously rely on careful planning and coordination with multiple suppliers and trust in them to deliver raw materials on time. It works particularly well for manufacturers that produce various products but have limited warehouse storage space - for instance, a car factory might only need to store components required for each model of their cars in addition to the final vehicle itself - so as not to wait until all parts have arrived before starting production on individual customer orders.

JIT also helps reduce waste related to overproduction. Overproduction occurs when manufacturers produce more products than the market demands; this adds up in production expenses, storage fees, shipping expenses, and potentially discarded products, further adding costs associated with production processes. A successful JIT system ensures that only necessary quantities are produced while reducing or eliminating excess amounts altogether.

Utilizing a JIT inventory system can also reduce the risk of lost or defective products during production and when held for too long in storage. Defects caused by manufacturing process errors or storage issues can result in costly rework or inspection processes; JIT minimizes these expenses by ensuring products are made upon customer order with only appropriate quantities sent to customer addresses.

Just-in-time inventory systems offer another significant benefit for companies: increasing efficiency. With fewer raw materials, employees can focus more on processing and distributing orders rather than sitting idle on inventory shelves. Plus, less of your company's cash goes toward keeping things on the frame instead of being spent elsewhere!

Implementing a Just-In-Time inventory strategy can be challenging for some companies, notably smaller enterprises. The approach relies on accurate forecasting, which can be challenging to execute accurately. It requires working with multiple suppliers, which may present additional logistical or quality issues that must be managed.

Customer Service

Customer service relies heavily on providing fast and accurate information to retain customers. Unfortunately, many customer issues arise due to employees needing access to it at the moment of need; digital transformation allows employees to receive what they need just when needed - strengthening your team and improving performance overall.

The Just in Time (JIT) approach to business operations is a logistics strategy designed to reduce inventory costs by quickly delivering products, raw materials, and parts directly to production facilities when needed, thus eliminating storage needs and production waste. Successful implementation requires maintaining close relationships with suppliers while anticipating future orders.

If your business operates on a Just-in-Time production schedule, having a dependable Just-in-Time shipping partner that provides services when they are needed can be crucial. At Expedited Transportation, our expert staff and superior customer service manage your shipments for you - so you don't have to!

Just-in-time learning can help your team respond instantly to customer inquiries and strengthen customer loyalty. Instead of holding training seminars or attending sessions for new hires, this digital transformation allows your team to access the required knowledge and ongoing training into an integrated part of the workflow.

Customer contact centers require rapid and accurate responses to retain customers. Unfortunately, traditional new hire orientation and onboarding sessions do not provide enough information about each unique situation that might arise during an interaction.

Inventory Holding Costs

Inventory holding costs are a significant expense affecting profit and loss statements. By eliminating waste and obsolete or dead stock from lists, just-in-time inventory models help decrease inventory holding costs significantly and cut warehousing expenses as companies only need space for items they produce.

With just-in-time inventory management systems, purchase orders are only sent out once it has been determined how many products need to be made in a given period. Suppliers then dispatch these materials directly to your production facility so you don't have backlogged inventory in your warehouse.

Eliminate these costs altogether with a pull system, which involves replenishing only those materials and parts used during production. This can be accomplished via vendor-managed inventory systems such as Kanban cards or an Electronic Data Interchange (EDI) platform to electronically exchange inventory/purchase information.

Just-in-time inventory systems offer many advantages, including lower operating costs, enhanced customer service, and superior production quality. JIT can also shorten lead times and help respond more quickly to fluctuations in market demand. Unfortunately, JIT may come with certain downsides as well.

One challenge involves the difficulty of reworking orders for customers who change their minds or wish to return items. At the same time, another entails depending on your suppliers for performance and timeliness, which can directly impact your profits. Furthermore, manufacturing processes are exposed to higher raw-material costs, which could force you to raise prices on finished goods.

One issue with long-term inventory storage is inventory degradation caused by incorrect temperature storage, physical damage, and obsolescence. Suppose this becomes an issue for your business; disposing of or reworking old inventory may become costly. In that case, the key to successful inventory management is balancing too much stock and too little.

Timely Delivery

E-commerce has grown dramatically over recent years, accounting for an estimated 13% of global retail sales in 2018. To stay ahead of this explosion of growth, retailers need warehouse space and inventory management systems that are flexible enough to process large orders quickly and efficiently.

ShipBob provides an ideal fulfillment service solution for ecommerce companies seeking to offer fast delivery times - ultimately increasing conversion rates and revenue potential.

ShipBob fulfillment services must work seamlessly with an ecommerce business's warehouse and inventory management systems to make this work. Otherwise, getting products out quickly may become challenging in meeting customer demands.

JIT delivery (Just-In-Time delivery) is a supply chain inventory management strategy in which products are sent directly to manufacturers as needed, thus cutting inventory costs. Accurate demand forecasting ensures that producers do not produce or purchase more than necessary, reducing waste while increasing efficiency.

JIT delivery also reduces warehouse storage and inventory control costs, allowing companies to devote these resources to more productive activities, leading to greater profits overall. JIT delivery also promotes collaboration among suppliers and manufacturers while speeding up production.

JIT delivery offers another advantage: eliminating buffer inventory. Buffer stock typically exists throughout a supply chain to cover any unexpected shortages in production steps without delay. Still, JIT eliminates this by keeping a little list at each stage so any issues can be dealt with immediately when they arise.

Proper supply chain management is essential in all forms of delivery, especially with JIT deliveries, as products must not only move smoothly but also arrive at their destinations on schedule to eliminate waiting or storage costs.

Pros of Just-In-Time (JIT)

• Inventory Reduction: JIT helps reduce inventory levels, lowering the carrying costs.
• Cost Efficiency: By minimizing storage costs and reducing waste, JIT contributes to overall cost efficiency.
• Quality Improvement: JIT often leads to better quality control as defects can be detected and corrected quickly.
• Increased Cash Flow: Lower inventory levels mean less money is tied up, improving the business's cash flow.
• Flexibility: JIT allows companies to adapt more quickly to changes in customer demand.
• Resource Optimization: With JIT, resources are only used as needed, leading to more efficient use of factory space and manpower.
• Simpler Logistics: With fewer items in inventory, handling and logistics become simpler and more manageable.
• Faster Response to Market Changes: JIT enables quicker adaptation to market trends and shifts in demand.
• Enhanced Supplier Relationships: JIT often involves long-term supplier relationships, leading to better terms and reliability.
• Environmental Benefits: Lower inventory levels mean less energy required for storage, contributing to a smaller carbon footprint.

Cons of Just-In-Time (JIT)

• Supplier Risk: JIT is highly dependent on reliable suppliers; any delay can disrupt the entire production process.
• Lack of Backup Inventory: With minimal inventory, there must be more cushion for errors or unexpected demand spikes.
• Initial Implementation Cost: Setting up a JIT system can be expensive and time-consuming.
• Complexity: JIT requires sophisticated planning and coordination between various departments.
• Vulnerable to External Factors: Natural disasters can severely disrupt a JIT system.
• Quality Risks: With rapid production cycles, there's a risk of quality issues going unnoticed.
• Employee Stress: The fast-paced environment can be stressful for employees, potentially affecting job satisfaction.
• Limited Economies of Scale: JIT may not be suitable for businesses that benefit from bulk purchasing or production.
• Market Risk: A sudden change in market demand can lead to shortages or overproduction.
• Requires Cultural Shift: Successful JIT implementation may require a change in organizational culture, which can be challenging.

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.
