TWI – Training Within IndustryHistory of the TWI methodology:• Developed in 1940’s in U.S.A. to quickly develop and

re-train unskilled work force in the industry

• TWI gave excellent results. All companies applied it reported: increased productivity (> 25%) reduced training time (> 25%)

• After the war USA exported the TWI methodology in Japan to help the industrial rebuilding

• The TWI methodology was adopted by Toyota, improved and become part of the T.P.S.

• Today TWI is part of the “lean management” tools used worldwide to standardize the work, standardize the training of workers and quickly raise skills on production floors.

What is TWI?The Training Within Industry TWI program is all about training and coaching supervisors (“train the trainers”) giving them:

1. Knowledge of the work2. Knowledge of the responsibilities of the job

The 3 J’s programJI — Job Instruction Training — to train supervisors how to train employees to quickly learn and consistently remember how to do any job correctly and safely.

JM — Job Methods Training — to train supervisors how to lead teams to quickly improve job methods to produce more in less time, making the best use of resources.

JR — Job Relations Training — to train supervisors how to lead people in ways that prevent and quickly resolve problems.

The J.B.S. are developed to support this phase of program.

JBS

The J.B.S.• Synthetic way to standardize the work optimizing the skill

transfer to new employees

• It focus on main points and not list each single detailed motion

• It is not a “Complete Instructions Manual” for the job that can be handed to the employees

• The main purpose is to help the instructor organize the job in their mind and determine the best way to convey this knowledge to the employee

• It’s written by the instructor as a tool “from us to our-self”

• They are organizing tools for the trainer, not for handing over to the learner

What is inside a JBS• Complete information about the task, task number, parts and

components used, tools, material, safety equipment, etc…

• Major Steps: As it says – only major steps Always start with a “verb” Single short sentences

• Key points: Safety Quality Tip and tricks (knowledge based on experience)

• Reasons

First part – Task information

Second part – Job breakdown

MAJOR STEPS

Any logical segment of the operation that helps advance the job or adds value to the product.

• List all the steps in the actual sequence performed usually

• Focus on the operator point of view

• Major steps is not a full description of motions to be done

Example:Screw the winch flange on deck Yes – is a M.S.

Get screw driver from the toolbox No - isn’t a M.S.

KEY POINTSAny important issue related to quality, safety and information to know to make the job better.Each M.S. may have more than one K.P.

Typical key points are info that:

1. Make the job 2. Break the job 2. Injure the worker 3. Make the work easier

Use graphic symbol to make the JBS visual:

REASONThere is a difference between child education and adult education.Most of the adults while learning need to know the reason – WHY?

• Quality precautions• Waste prevention• Health precautions• How the final result

should look like• How match one part to

the other

Third part – Pictures / Training aid

USE PICTURE FOR EFFICIENT VISUAL

REPRESENTATION OF KEY POINTS

Check pressure. The right value must be between 0.5 and 2.4 bar

What’s better?

Practical example – Replace a wheel

• Efficient way to standardize the work• Rely on real technical document instead of

memory• Strong tool for a fast and effective training• Starting point for a real “kaizen” on the floor• Give strong value to the “supervisors” (team

leaders)

Benefit of a well done set of JSBs
