TWI Job Methods (TWI JM) is a structured method for questioning every detail of a job, removing waste and creating a safer, simpler and more effective method using available resources.
TWI Job Methods – practical Kaizen led by the people who do the work
Develop daily improvement capability close to the process—without waiting for a large project, a technology investment or an external expert to redesign every job.

When improvement is too dependent on experts
Job Methods is useful when frontline knowledge is abundant but there is no simple, repeatable path from observation to an implemented new standard.
Extra movement, waiting, handling and checking are accepted because the job has always been done that way.
Improvement happens during workshops, while daily leader routines return to firefighting.
Teams seek equipment or automation before simplifying the existing method and flow.
The working method
Question every detail, then design and apply a better method
JM combines close observation with a disciplined sequence. It keeps improvement practical, evidence-based and owned by the people closest to the work.
The Job Methods cycle
5W1H exposes why each detail exists. ECRS turns that challenge into an actionable redesign using existing people, machines and materials.
- Break down the job and list every relevant detail
- Question why, what, where, when, who and how
- Eliminate, combine, rearrange and simplify
- Sell the proposal, obtain approval, put the new method to work, give credit and follow up
From workshop to operating system
How we build a working Job Methods routine
The aim is not a one-off idea campaign. It is a practical improvement habit supported by leaders, standards and clear decision paths.
Choose a real constraint
Start where motion, waiting, ergonomics, cost or capacity visibly limits the process.
Practise on the current job
Break down details, challenge them with 5W1H and create testable options with ECRS.
Run and measure experiments
Compare the new method with the baseline for time, effort, safety, quality and flow.
Standardise and repeat
Update the standard, teach the new method and build a leader cadence for the next improvement.
Management evidence
Measure whether the new method genuinely improves the work
A good JM result is not the number of ideas. It is a safer, simpler and more capable process that the team can sustain.
| Measure | What it answers | Example |
|---|---|---|
| Labour content | Did the method remove work rather than move it elsewhere? | Minutes per unit or operator touch time |
| Movement and handling | Was unnecessary motion or transport removed? | Distance, reaches, transfers or handling steps |
| Quality and safety | Did simplification reduce risk and error opportunities? | Defects, rework, ergonomic exposure and near misses |
| Implementation rate | Can teams turn analysis into a maintained standard? | Tested changes adopted and stable after review |
Proof from real organisations
TWI creates improvement capability that can scale
Job Methods is strongest when it works alongside Job Instruction, leader development and a clear operating system for standards and learning.

FAQ
Frequently asked questions about TWI Job Methods
JM is simple to explain, but its value depends on how it is connected to real work and leader behaviour.
Is Job Methods the same as a suggestion system?
No. A suggestion system captures ideas. JM provides a structured way to analyse the current job, develop a new method, gain support, test it and establish it as the standard.
What is the role of 5W1H in Job Methods?
5W1H is used to question the purpose, place, sequence, person and method of every detail. It prevents teams from improving a step that should first be eliminated.
How does ECRS fit into the method?
ECRS turns questioning into design choices: eliminate, combine, rearrange and simplify. Elimination should be considered before optimisation or automation.
Can JM be used in offices and services?
Yes. The detail may be a handoff, approval, data entry or queue rather than a physical movement, but the logic remains the same.
How do we avoid improvements that create problems elsewhere?
Define the process boundary and measures before testing. Review safety, quality, flow, workload and downstream effects—not only local cycle time.
Where should we start?
Select one repetitive job with visible waste and a supportive frontline leader. A contained pilot makes the method tangible and produces material for scaling.

Turn frontline knowledge into better methods and new standards
Describe a process where waste, ergonomics or capacity is limiting results. We will help you choose a pilot and build a repeatable Job Methods routine.
