Six Big Losses

Continuous Improvement, Lean Manufacturing, Maintenance, Overall Equipment Effectiveness (OEE), Problem Solving Techniques, Process Improvement, Productivity, Root Cause Analysis, Six Sigma

Objective:

To categorize and provide a framework for understanding and eliminating the most common causes of productivity loss in manufacturing.

How it’s used:

A key concept in Total Productive Maintenance (TPM), these are: Breakdowns, Setup and Adjustment Losses, Small Stops (Idling and Minor Stoppages), Reduced Speed, Startup Rejects (Defects in Process), and Production Rejects (Rework and Scrap).

Pros

Provides a structured way to identify and prioritize OEE (Overall Equipment Effectiveness) improvements; Helps focus efforts on critical areas of equipment-related waste; Encourages a systematic approach to problem-solving.

Cons

Primarily focused on equipment-related losses, may not cover all sources of inefficiency in a broader business context; Requires accurate data collection to quantify losses effectively.

Categories:

Lean Sigma, Manufacturing, Problem Solving, Quality

Best for:

Systematically identifying and tackling the primary causes of equipment-based productivity loss to improve Overall Equipment Effectiveness (OEE).

The Six Big Losses methodology serves various industries, particularly manufacturing, automotive, aerospace, and food processing, where maximizing equipment efficiency is essential. Applications include assembly lines, CNC machining, and packaging operations, aiding engineers and operations managers in identifying bottlenecks that hamper production rates. This methodology can be initiated during the planning phase of a new production line or as part of ongoing maintenance programs. Cross-functional teams involving maintenance technicians, production operators, and quality control personnel can collaboratively assess and document each loss type, leading to targeted improvement initiatives. For instance, regular analysis of breakdown trends can guide preventive maintenance schedules, while monitoring small stops can lead to adjustments in machinery or training for operators. Implementing the Six Big Losses approach aligns with Lean Manufacturing principles, as it systematically categorizes and prioritizes instances of waste, transforming data into actionable strategies. Encouraging a culture of continuous improvement, this methodology can pave the way for enhanced team collaboration and the adoption of best practices in equipment management, ultimately driving improvements in product quality, operational uptime, and profitability.

Key steps of this methodology

Identify the Six Big Losses relevant to the equipment.
Analyze data concerning each specific loss type.
Prioritize losses based on impact on productivity and OEE.
Implement targeted strategies to address prioritized losses.
Monitor and measure the effectiveness of implemented strategies.
Iterate the process based on results and continued improvements.

Pro Tips

Implement a Root Cause Analysis (RCA) framework specifically designed for each of the Six Big Losses to uncover underlying issues effectively.
Leverage real-time data analytics for continuous monitoring of equipment performance, enabling proactive adjustments before losses escalate.
Establish cross-functional teams including operators and maintenance personnel to collaboratively investigate loss events, fostering a shared ownership of equipment efficiency.
