You know what the problem is, but you cannot solve it? The 5 Whys technique will allow you to quickly dissect the problem and reveal its underlying causes. Unpredicted problems may occur in any team or process. However, problems are just symptoms of deeper issues.

This is why your team needs to focus on finding the root cause and tackle it properly. The 5 Whys technique is one of the most effective tools for root cause analysis in the Lean management arsenal. Every team faces roadblocks in its daily work. However, using the 5 Whys will help you find the root cause of any problem and protect the process from recurring mistakes and failures. The 5 Whys method is part of the Toyota Production System. Developed by Sakichi Toyodaa Japanese inventor and industrialist, the technique became an integral part of the Lean philosophy.
One of the key factors for successful implementation of the technique is to take an informed decision. This means that the decision-making process should be based on an insightful understanding of what is actually happening on the work floor. In other words, the root cause analysis process should include people with practical experience.Open dialog javafx
Logically, they can give you the most valuable information regarding any problem that appears in their area of expertise. When applying the 5 Whys technique, you want to get to the essence of the problem and then fix it. Actually, the 5 Whys may show you that the source of the problem is quite unexpected. Often, issues that are considered as a technical problem actually turn out to be human and process problems.
This is why finding and eliminating the root cause is crucial if you want to avoid iteration of failures. You can notice that the root cause of the initial problem turned out to be something completely different from most expectations. Furthermore, it is obvious that it is not a technological, but a process problem. This is typical because we often focus on the product part of the problem as we neglect the human factor.
Therefore, the 5 Whys analysis has the purpose to inspect a certain problem in depth until it shows you the real cause. The 5 Whys technique may help you achieve continuous improvement at any level of your organization.You can access this content by purchasing a subscription. Want to access our free content?

Key vocabulary: area model dividend division divisor quotient rectangular array remainder.Students will begin this lesson with a task question that requires them to apply their knowledge of powers of ten and spatial reasoning. Currently my class is learning about the solar system in science so I devised a story problem centered on this content.
I display the question and allow the students time to discuss the question in their groups.
You bought a telescope that could magnify times. If you are on the satellite, using your telescope, would you be able to watch what people on Earth are doing?
Explain your thinking. You would need a telescope with more magnification or your satellite would need to be orbiting closer to the earth.
In this lesson I want students to focus on the process of multiplying and dividing with a power of ten. I want them not only to solve a problem set with this process but be able to explain their thinking. I provide the students with ten problems and ask them to work on them with their neighbor. I ask them to show and explain their thinking. In previous lessons we have showed the movement of the decimal by drawing decimal jumps underneath the number.
I also want you to explain your thinking in each step of solving the problems.
7. Solve division problems using area models and rectangular arrays (FP)
You can use your decimal diagram for reference if you get stuck. I allow the students about ten minutes to work on the problems. During this time I circulate the room and look for students who might need some extra help. The most common problem I find among students is their inability to determine which direction the decimal goes.
Is the number getting bigger or smaller when you multiply? Then I have them compare that information to the work. Well then, does the number you're working with have to be bigger when you're done with our decimal jumps? This seems to get students back on track. To wrap up this lesson I have students play a quick game with dice. The concept of the game is to have students solidify the idea that powers of ten are multiples of ten. I explain the game to the students and model a turn on the projector.
I allow them to play with a partner for about ten minutes. At the end of the game I bring students back to the whole group and ask them to tell me something they know about powers of ten.Standard: M Use whole-number exponents to denote powers of Standard: Math. Standard: CC. Start Practicing! Ten to a poweror exponentis called a power of tenand is equal to the product of that many tens. In this case, 10 is raised to the power of 3, or the third power.
To multiply a whole number by a power of ten, add the same number of zeros to the end of the number as the power of ten. In this case, the power is three. So, add three zeros to the end of 70 to find the product.

I can explain patterns when multiplying a number by powers of Repeat it with me. Today we are going learn what powers of ten are and the benefit of using them. This worksheet will guide students through the web interactive we are going to use today. I start the interactive at oak tree branch with leaves. We are going to zoom out 10 times which is like multiplying by I fill in the distance only on the first line of the chart.
I then hit the increase button again and it brings us to the nearby trees scene. If we multiply 10 x 10 that is the same as multiplying by what? Explain your thinking? As a class we go back and fill in the "or" column of the worksheet for the second line so it reads x We continue to go through the interactive, filling in the Distance and Or column.
Up until this point in the the unit, I have worked on laying the ground work for understanding powers of ten. Now it is time to introduce what a power of ten looks like and how to write it. Did anyone get tired of writing x 10 while viewing the interactive?
Would you like an easier way to write it? I refer back to the worksheet that we just completed and begin at the second line where the distance is 10 x I ask the students to tell me the number of tens I multiplied. I then show them how to write 10 to the power of 2.
I do the same for the next line this time focusing on how to say the index notation. Say it with me.On this post, I will share how you can get multi-step error analysis math tasks for free! Error analysis is when students analyze an example of student work looking specifically for the error made by the student.
As you can imagine, error analysis is a higher level thinking activity because it requires a deeper understanding of the skill or concept to be able to identify and correct errors. When I received feedback on my error analysis math tasks from a teacher wanting to see more multi-step word problems included, I knew this was a definite need and would be very helpful. My students often struggle with multi-step word problems. Allowing them to analyze and discuss work that shows the same errors they make when solving multi-step word problems would help them see these problems through another lens.
When creating error analysis tasks, I always try and include a variety of errors that I see my students make. The math errors in this free set include:.
