POKA-YOKE - A Lean Strategy to Mistake ProofingTimothy Wooi
A Lean Strategy in Human Error Prevention aims to detect and correct possible error immediately, eliminating defects at the source.
Poka-Yoke overcome the inefficiencies of inspection through the use of automatic devices that seek,
1.Not to accept a defect for the process
2.Not to Create a Defect
3.Not to Allow a Defect to be passed to the next process
Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.
The concept was formalized, and the term adopted, by Shigeo Shingo as part of the
Toyota Production System.
It was originally described as baka-yoke, meaning "fool-proofing“ or “idiot proofing” but the name was later changed to the milder poka-yoke.
its a general term used in cnhi india to allocate public interest and used as a tern in tractor company to see what things are working properly and what things are not working properly

Jidoka is a technique to provide machines and operators with the ability to detect when an abnormal condition has occurred and immediately stop the work. Also known as autonomation, meaning "automation with human intelligence", Jidoka is the tool of built-in quality and supports just-in-time production. With an effective Jidoka system in place, companies can ensure that defects are not passed on to the customer, equipment breakdown is prevented and operators can work on multiple machines instead of wasting their time watching them.
In this training presentation, you will learn the key concept and principles of Jidoka, understand the tools and the four-step process of Jidoka, as well as gain insights on developing an effective Jidoka system.

Poka-yoke is a quality assurance technique developed by Japanese manufacturing engineer Shigeo Shingo. The aim of Poka-Yoke is to eliminate defects in a product by preventing or correcting mistakes as early as possible. Poka- yoke has been used most frequently in production environments. Production defects or errors are always the key concerns of any production industry. The success of any organization depends on the quality of product especially right product produced.

Poka Yoke - Fundamentals by Praneet SurtiPraneet Surti
A presentation on the Introduction, Purpose, History & Origin, Concept, Principles, Methods, Types & Implementation of Poka-Yoke [Mistake Proofing] in any manufacturing or service setting.
It’s a quality assurance process introduced by Japanese engineer Shigeo Shingo. This term is used in Japanese language as “Poka” meaning mistake and “Yoke” meaning prevent i.e. mistake preventing or mistake proofing technique.
The purpose of Poka-Yoke is to develop processes to reduce defects by avoiding or correcting (design to show alerts or warning messages to the user) mistakes in early design and development phases.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

3. POKA-YOKE
• ‘POKA’ means ‘Mistakes’ & ‘Yoke’ means ‘Avoid’.
• It’s objective is to achieve Zero Defects.
• Poka-yoke is a quality assurance technique, the aim of poka-yoke is to eliminate
defects in a product by preventing or correcting mistakes as early as possible.
• Term adopted by Dr. Shigeo Shingo as a part of Toyota production System in
1960.
• It was originally described as “BAKA-YOKE”, but this name mean “fool-
Proofing” so the name was changed to the Poka-yoke.

• 1. Guide pin
• 2. Blinking light and Alarms
• 3. Limit Switches
• 4. Proximity switches(sensor)

17. The methodology of poka-yoke are:
1. Identify Problem
2. Observation at workstation
3. Brainstorming for idea
4. Select best idea
5. Implementation Plan and Implementation
6. Monitor and sign off
18. Step 1: Identify problem
In this stage the complaints coming from the customers (Both internal and
external customer) are collected. The principle of standard is determine by
considering various criteria’s like number of complaints from the customers&
PDI(pre dispatch classify), the quantity of detected by quality control, materiality
defects and then data is collected broadly. As per the analysis all results of the
collected data company plans for developing poka-yoke system for the selected
problem. In the way in first stage the problem is selected
Step 2 :Observation at work stations
In this step the actual on site study of the problem is carried out. The causes behind the
problem are sort out by using fishbone diagram (fishbone diagram is cause and effect diagram
given by Japans management guru Ishikawa).The causes may be related to man skill, machine,
material or method accordingly the complete sorting is carried out.
19. Step 3: Brainstorming for Idea
This is a technique to capture all creativity and skills of employee’s .In brainstorming
session the problem under study is put forward to committee. Then study problem given by all
members and give various solutions to avoid that defect. As each person has one uniqueness this
step concludes with various alternative solutions for same problem.
Step 4: Select best ideas
After getting all various alternative solutions it is time to select best one out of all
collected solutions. Criteria for selection may be cost, problem create after installation, time
required, changes in existing system, opportunity to develop new solutions, simplicity in
operation etc. By referring all selection criteria’s committee concludes With one best solution.
Step 5: Implementation plan and implementation
This step is concerned with implementation planning& installation. It deals with material
requirement, processing the material and finally manufactured mechanism is implemented at
actual working site.
20. Step 6: Monitoring and sign off
The produced products are checked for defects under study also the performance of poka yoke system is
also monitored and project is shut downed.
