Meet the Culprits: The 7 Wastes of Lean

Imagine money leaking from various holes in your business. That’s essentially what these wastes represent: lost opportunities and resources. Now, let’s shine a light on each culprit:

1. Overproduction:

Making more than customers need leads to excess inventory, tying up capital, taking up space, and risking obsolescence. Fight back with tools like Kanban (visual production cues) and demand forecasting.

2. Inventory:

Stockpiling raw materials or finished goods beyond immediate needs. This creates a hidden monster,obscuring quality issues and increasing the risk of damage. Tame the beast with Just-in-time (JIT) delivery, ABC analysis (prioritizing high-value inventory), and consignment inventory (suppliers manage on-site stock).

3. Defects:

Products not meeting quality standards. Imagine unhappy customers and wasted resources. Strike back with quality control measures, Poka-Yoke (mistake-proofing), and a zero-defect culture that empowers employees to own quality.

4. Motion:

Unnecessary movement of people or materials. Think wasted energy, lost time, and potential injuries. Get things moving efficiently with workflow optimization, improved plant layout, and automation for repetitive tasks.

5. Waiting:

Idle time for people or equipment. This waste screams lost productivity and longer lead times. Unleash your full potential by identifying and eliminating bottlenecks, implementing preventive maintenance, and empowering employees to solve problems proactively.

6. Transportation:

Moving materials or products more than necessary. This adds unnecessary costs and hurts the environment. Optimize your routes with efficient planning, consider sourcing materials nearby, and leverage cross-docking for direct transfers between suppliers.

7. Over-processing:

Performing unnecessary tasks that don’t add value. This extends lead times and increases costs. Simplify your processes by eliminating non-value-adding activities. Use value stream mapping to identify and eliminate waste, and involve customers to ensure processes truly meet their needs.

Beating the 7 waste of lean : Paving Lean frameworks through Zero loss mindset

Lean Manufacturing has a Lot of tools to beat the 7 waste. However It is not Like Exact math, You need to understand which Losses are causing your Cost bleeding. After that Plan the Continuous perth based on bussiness Condition and organization Priorities. there are two key tools to as Zoro Step during Lean framework Deployment.

Cost tree analysis

this tools Like detective which give you alert who are the Culprits. Cost tree analysis Putting all your manufacturing Cost and See which  Part are the bleeders. By finding ger-prominent Bussines part or process bleeder, You can Step forward into the details.

Zero loss Journey

this tools Emphasis What the doal Looks Like as ideal as possible. It not consider Current Complexity and Current machine or technology limitations. By defining What the good Looks like we can Understand the path to Lean manufacturing.

Hoshin Kanri

Hoshin Kanri Put all of item above into action across the Organizations. yo need fo ties back all your program with the departement Success metrics. Also in the most of Cases ties aswell with Individual metrics. Hosin Kanri Usually done Annually the aim wore to drive Zero loss Journey into motion in cach annual year.

Observing your production processes is key. Utilize tools like Process Maps, Takt Time, and Skill Matrix to identify wasted motion, unnecessary steps, and areas for improvement. Track metrics impacted by each waste, and apply specific Lean tools like Kanban, Just-in-time, and Poka-Yoke to address them directly.

Which Waste is the Big Bad Wolf?

7 waste of lean which harmfull to the business were inventory and defects.

Based on study after covid 19 many industries due to high level inventory and causing money doesn’t flow. Inventory also create domino effect of the increased defect due to lack of ideal storing condition.

In operation side defect and inventory pose some risk which. Excess inventory strains your operational efficiency area storing,forklift movements, risk of safety and many more. while defects impact customer satisfaction and brand reputation in operation side reworkmay hinder operation pace and labor efficiency. Pay close attention to these areas for maximum impact.

The Cost of Inaction: Counting the Wasteful Dollars

Studies reveal that the 7 wastes of lean can drain up to 30% of a company’s operating budget. Consider the impact:

• Overproduction: Excess inventory ties up capital that could be invested in growth initiatives.
• Inventory: Storage costs, product obsolescence, and potential markdowns eat into profits.
• Defects: Rework, scrap, and warranty claims significantly impact the bottom line.
• Motion: Employee fatigue, potential injuries, and lost productivity erode efficiency.
• Waiting: Idle time, missed deadlines, and potential lost sales directly impact revenue.
• Transportation: Increased fuel costs, environmental impact, and longer lead times hinder competitiveness.
• Over-processing: Extended development cycles, increased labor costs, and potential product delays affect market responsiveness.

7 waste of lean Real-World Examples: Bringing the Wastes to Life

Overproduction:

Imagine a clothing manufacturer churning out winter coats in July, anticipating a harsh winter that never materializes. The excess inventory becomes a burden, requiring costly storage and risking potential markdowns.

Inventory:

Think of a supermarket overflowing with expiring perishable goods. Not only is valuable shelf space wasted, but disposal costs add insult to injury.

Defects:

A car manufacturer producing vehicles with faulty paint jobs not only incurs rework costs but also risks brand damage and customer dissatisfaction.

Motion:

Picture an employee walking across a vast factory floor multiple times to retrieve tools or materials. Each unnecessary step translates to lost productivity.

Waiting:

An assembly line halted due to a lack of necessary components creates frustrating idle time for workers and delays production.

Transportation:

Consider a company unnecessarily shipping raw materials across continents when closer suppliers exist, increasing lead times and carbon footprint.

Over-processing:

Imagine a software development team manually testing every line of code, neglecting automated testing tools that could save significant time and effort.
