Hey everyone, welcome to the activity solutions lecture. To identify the jidoka solution. You are given two situations and each situation had two solutions. Your job was to identify that solution, which used the lean tool jidoka. I hope you have the correct answers. Let's begin reviewing each answer.

Situation one. Imagine you are a research and development expert at a printer manufacturing organization. The printers that your organization manufacturers are world class. However, these days many of your customers are complaining about issues with the print quality. As an r&d expert, you test the printer for these complaints and observe that at times the paper gets jammed in your printer. Your printer doesn't detect the paper jam and continues to keep working.

As an r&d expert, which of the two solutions would you use to resolve this situation? option one, you will create a mechanism of flashing an indicator whenever paper gets jammed. The indicator will ask the user to stop the printer. However, you will allow the printer to continue its operation until the user stops it manually. You think this will allow the user the autonomy to use the printer at his will option two. Here, you will create a mechanism of stopping the printer completely if the paper gets jammed.

The indicator will also flash stating that the paper is jammed and the printer will start only when the user removes the jammed paper from the internal roller. Okay, given the two solutions for the problem The correct answer where jidoka is used is option two. jidoka means automation with human intervention. That is, when an error occurs, the process stops completely until a human intervenes and corrects the error. In the second solution when the paper jam occurs, the printer stops completely until a human intervenes and removes the jammed paper manually. This is a classic example of judoka situation to you are working as a plant manager in a cold cream manufacturing process.

When I refer to cold cream, I'm referring to cold frames such as Vaseline, bonds, and others. In this process, the series of cold cream boxes move on a roller bait and the cold cream is automatically poured in each box. Your organization has invested heavily in this type of an automation. However, there is one problem. At a few instances, the machine that pours cold cream automatically in each box doesn't remain calibrated. As a result, if it is supposed to pour 50 grams of cream, it pours more or less than the required amount.

This had further cause this satisfaction amongst your customers. How would you solve this situation as a plant manager option one, you will implement 100% or rating of each cold cream box in the next step. That is you will ask an employee to measure the weight of each cold cream box manually. After the cream is poured in the box. Option two, you will automate the cold cream weighing process. That is as soon as the cold cream box is filled Then, the roller belt throws the box into a weighing machine.

Now if the weight of the box is within the threshold, the process continues its operations. However, if the weight goes beyond the threshold, this signals the machine to stop the entire process immediately. An employee is then required to calibrate the machine to pour the cream in the right amount again. so in this situation, option two is the correct choice. You are automating the process by allowing a weighing machine to check the weight of each cold cream box automatically. Then, if the weight of any cold cream box goes beyond the given threshold, the machine stops asking a human to intervene and remove the error.

This is effective use of jidoka. That brings us to the end of this lecture. Thank you for attending. See you in the next one.
