Continuous improvement doesn’t happen by accident. It happens when people at every level of an organization are equipped to see opportunities, think critically about the work in front of them, and take action using a clear, structured approach.
In a recent IMEC webinar, Mastering Job Methods: Unlocking Continuous Improvement with TWI, I explored how the Training Within Industry (TWI) Job Methods program gives frontline leaders and teams a practical, proven way to improve how work gets done, every day, on the shop floor.
Originally developed during World War II to rapidly upskill the industrial workforce, TWI remains one of the most effective, and often underutilized, continuous improvement tools in manufacturing today.
What Is TWI Job Methods?
At its core, TWI Job Methods (JM) focuses on one fundamental question:
How can we make the job easier, safer, better, and more efficient—without sacrificing quality?
Rather than relying on large, complex improvement initiatives, Job Methods empowers supervisors and team leads to improve work incrementally. It does this by breaking jobs down and examining each step with intention.
Job Methods follows a simple, four-step approach:
- Break down the job
- Question every detail
- Develop the improved method
- Apply the new method
This structured thinking process helps teams move past “this is how we’ve always done it” and instead focus on practical, sustainable improvements.
Step 1: Break Down the Job
A job breakdown is the starting point for all job methods improvements.
Many organizations skip this step and jump straight to solutions. Listing all details gives a complete record and accurate picture of how the job is done. It also gives us the opportunity to identify many details about a job that may have never realize were there.
Detail means every single movement that is done.
When teams take the time to clearly define the work as it is performed, inefficiencies, redundancies, and safety concerns often become visible for the first time.
Step 2: Question Every Detail
Once the job is broken down, each step is challenged by asking questions such as:
- Why is this step necessary?
- What is its purpose?
- Where is it done?
- When is it done?
- Who does it?
- How is it done?
From there, teams look for opportunities to:
- Eliminate unnecessary steps
- Combine steps where possible
- Rearrange the sequence
- Simplify the work
This step isn’t about criticism, it’s about curiosity. Job Methods creates a safe, structured way to challenge processes without blaming people. The focus stays on improving the work, not pointing fingers.
Step 3: Develop the Improved Method
After questioning each step, the team develops a new method that incorporates improvements while still meeting safety, quality, and production requirements.
One key principle I always emphasize: a good improvement makes the job easier for the operator, not harder.
When workers see that changes reduce frustration, unnecessary motion, or risk, buy-in increases dramatically. Many of the most successful Job Methods improvements are small, adjusting a layout, changing the order of tasks, or clarifying responsibilities, but over time, those small changes add up to meaningful results.
Step 4: Apply the New Method
Even the best idea fails if it isn’t implemented effectively. The final step focuses on making sure the improvement sticks by:
- Gaining approval from the appropriate stakeholders
- Training employees on the new method
- Following up to ensure the change is sustained
This reinforces an important point: Job Methods isn’t a one-time exercise. It is a continuous cycle of learning, improvement, and reinforcement.
Why Job Methods Works
One of the reasons Job Methods is so effective is that it is inherently people-centered.
Rather than relying solely on engineers or outside consultants, Job Methods equips supervisors and frontline leaders to improve the work they know best. This builds problem-solving capability throughout the organization and helps create a culture where improvement is part of everyday work, not a special project.
Job Methods also complements Lean, Six Sigma, and other continuous improvement efforts. It provides a practical way to make improvements at the job level, where value is created.
Real-World Impact
Organizations that consistently use Job Methods often experience:
- Improved productivity and throughput
- Reduced waste and rework
- Safer work environments
- Higher employee engagement
- Stronger leadership skills at the supervisory level
Most importantly, Job Methods helps organizations sustain continuous improvement by embedding it into daily routines rather than treating it as an occasional event.
