When To Use Histogram And The Benefits To Your Business

1/12/2020

When you look at a glance at a graph with bars, it may look like you are looking at a bar graph when you are looking at a histogram. The truth is that they are both very similar but there is a huge feature that sets the difference between the two. The reality is that in bar graphs, the bars are always separated by continuous intervals. However, in histograms, this doesn't happen and the bars are always touching. Besides, it is also worth to mention that in a histogram, the x-axis is measured in ranges to define various parts of the data.

When To Use Histogram

One of the things that you need to know about histograms is that they are an excellent way of describing numerical x-value data. Here's an example: graphing the height of several merchants on the x-axis versus weight on the y-axis. But why should you use a histogram? Well, the reason is that the x-values have arithmetic values.

Learn to make a histogram.

Usually, bar graphs are used when relating uncompromising data, and histograms are used when linking arithmetical data. At times when not sure of what to do with a big set of measurements shown in a table, you can use a histogram to arrange and display the data in a more user-friendly and understandable format. It makes it easy to see where most of the values fall in a measurement scale, and how much difference there is. It is also helpful to create a Histogram when you want to perform the following activities.

So, when you need to summarize large data sets graphically, you should use a histogram since it will be a lot easier to understand. Besides, when you need to compare process results with specification limits, you can do it easily with a histogram. This way, you will be able to quickly know if the current procedure was able to produce good products. The specification limits may be the length, weight, density, the quantity of the materials to be delivered, or any other that may be crucial for the product of a given process.

Are you trying to construct a histogram?

In what concerns to communicate information graphically, a histogram is very intuitive for everyone. Besides, a histogram is also a great tool to help you in decision making. However, and even if you use a histogram, it is important to always make sure that the data that you have in hand is current. When it isn't or you simply don't know how or when it was collected, you shouldn't even consider wasting time trying to chart it.

Discover all you need to know to construct your histogram.

Benefits Of Using A Histogram

When you use a histogram, you will be able to improve your decision-making process since it will be easier to view the data graphically.
A histogram allows you to display the frequency of occurrences of data within an interval.
When you use the data that is displayed in a histogram, you can regulate statistical information.
A major benefit of histograms is that they allow you to determine trends.
You can use a histogram to make your picture clearer to read and to categorize your data into many diverse classes.

What Is a Histogram?

Simply put, a histogram is a type of graph that has a wide range of uses in statistics.
One of the best things about histograms is that they deliver a visual interpretation of numerical data. And they do it by showing the number of data points that lie within a range of values.
The frequency of the data which falls within each class is then shown by the use of a bar. So, the higher the bar in the histogram, the greater the frequency of data values.

Histogram Vs Bar Graph

Many people tend to confuse a histogram with a graph bar. However, and even though they are similar in shape since they both use vertical bars to display data, they are different.

Discover how to make a histogram.

Overall speaking, the height of a bar corresponds to the relative frequency of the amount of data in the class. So, the higher the bar, the higher the frequency of the data. On the other hand, the lower the bar, the lower the frequency of data. However, appearances may be deceiving. It is here that the similarities end between the two kinds of graphs.

The truth is that both graphs are different and the main difference is related to the level of measurement of the data.
If you think about it, bar graphs tend to be used for data at the nominal level of measurement. So, as you can easily understand, bar charts measure the frequency of categorical data, and the classes for a bar graph are these categories.

Not sure how to construct a histogram?

In what concerns the histogram, histograms are used for data that is at least at the ordinal level of measurement. The classes for a histogram are ranges of values.
However, this isn't the only difference between a histogram and a bar graph. After all, there is also a different way to order the bars.
When you are using a bar graph, it is normal that rearrange the bars in order of decreasing height. However, when you are using a histogram, you simply can't reorder the bars. They need to be displayed in the order that the classes occur.

Histograms And Probabilities

One of the uses of a histogram is related to probabilities. The truth is that discrete probability distributions can be represented with a histogram.
In case you are looking to construct a histogram that represents a probability distribution, then you will need to start by choosing the classes first. Notice that these should be the outcomes of a probability experiment. In terms of the width of each one of these classes, it should be only one unit. Looking at the heights of the bars of the histogram, you will be able to see the probabilities for each one of the different outcomes. So, when you construct such a histogram, you can also say that the areas of the bars are also probabilities.

Other Applications For Histograms

The truth is that histograms can be quite handy in a wide range of areas and not only for probabilities. In fact, when you are trying to compare the frequency of occurrence of quantitative data, you can use a histogram to depict your data set.

8 Supporting Activities Of The TPM

1/12/2020

0 Comments

TPM or Total Productive Maintenance program has the main goal of helping professionals achieve the goals that are set for a higher rate of utilization and productivity.

However, in order to start implementing TPM, there are 8 supporting pillars that you need to know about.

8 Supporting Activities Of The TPM

#1: Focused Kaizen:

During this first activity, you need to identify the problems related to equipment failures as well as set improvement goals in the kaizen event. The most important aspect during this stage is to ensure that the entire team is working together so that they can be able to discover the root of the problem and apply the solutions needed to the continuous improvement.

Learn more about TMP here.

#2: Autonomous Maintenance:

During this second activity of the TPM, the operators of the machines are the ones responsible for any machine adjustments that are required as well as for the minor maintenance of that specific machine. This may include cleaning, inspection, and lubrication.

#3: Planned Maintenance:

This activity of the TPM includes both preventive as well as predictive maintenance routines that should be based on the monitoring of the machines' behavior. The goal of scheduled maintenance is to make sure that no major breakdowns occur as well as to reduce the number of unplanned stops. So, this should lead to an increase in the productive capacity.

#4: Education And Training:

The goal of this activity in TPM is to make sure that there is a continuous improvement of the skills of the employees.

#5: Early equipment Maintenance:

The main objective here is to ensure that in the design stage, the piece of equipment that is added needs to be easy to maintain and operate. This includes the lubrication, cleaning, inspection, and even the accessibility of the machine's parts.

#6: Quality Maintenance:

When you implement the TPM process, you want to make sure that you get only quality products at the end. So, as it is easy to understand, this activity serves to detect and prevent errors during the production. So, by using lean tools such as andon and jidoka, machines will be able to detect and report when there is any abnormal condition.

This is what you need to know to start implementing TPM.

#7: The TPM Administration:

This is often an activity that is forgotten but is incredibly important. After all, the goal of the TPM administration is to improve the order processing procedures, the procurement, and even the scheduling. The main idea remains the same: waste elimination.

#8: Safety, Health, And Environment:

The last activity of the TPM is to set standards for the working conditions of all employees. This ensures that there is an elimination of potential health and safety risks. These can include the implementation of work standards or guards to ensure that all the machines are safe to use.

Bottom Line

While these may seem a lot to learn, the truth is that there are many advantages when you implement TPM. After all, some of the main benefits that this implementation can bring to your company include cost savings, more efficient workforce, optimized working schedule for all employees, equipment reliability, safer and cleaner workplace, and minimized delays, breakdowns, and production stops.

How to Implement TPM

1/12/2020

2 Comments

As you already know TPM stands for Total Productive Maintenance which is based on different Lean Manufacturing principles. And the truth is that when you want to implement TPM, you need to adapt it to the specifics of your own business or company. Nevertheless, you also need to keep in mind that there are 7 basic steps to implement TPM the right way.

How to Implement TPM

#1: Announce The Plans For TPM Implementation:

When you want to implement TPM, you need to keep in mind that the program will only succeed if the management is there to support. The support needs to come from the top. After all, there are always operators and employees who don't like changes and are always skeptical about what these changes can bring. So, to ensure that everyone can embrace the TPM program, you need to ensure that you announce it and that you also talk about the benefits such a program can bring.

Discover the pillars of TPM.

#2: Make Use Of A Pilot TPM Program:

One of the things that you can do is to find an area for a pilot TPM program. Maybe there is an area that is problematic and this is a great way to start with the TPM program and identify the SMART goals: Specific, Measurable, Attainable, Realistic, and Timed.

#3: Focus On Restoring Targeted Equipment To Prim Working Condition:

As soon as you have defined the pilot area, then you need to record a baseline standard for current productivity. Then, you need to use the 5S methodology (Sort, Set, Shine, Standardize, Sustain) to implement TPM.

Your focus should go first to the execution of an autonomous maintenance program, and then provide the needed training to equipment operators.

Learn more about the TPM process.

#4: Start Measuring Overall Equipment Effectiveness (OEE):

No matter how you want to track OEE. you need to ensure that all the unplanned stop times are well-documented. You need to make sure that you don't forget to add the reason for the stop. This is very important since it will help you identify major loss causes that will come up in the following step.

#5: Adress Major Loss Causes:

During this step, you will need to gather between 4 to 6 employees to discover one major cause of downtime. This team will be the one responsible for eliminating the loss cause as well as for scheduling planned stop tome to execute this initiative. As soon as the action is complete, the team will then need to measure OEE and restart the process in case it is needed.

#6: Implement Proactive Maintenance:

During this step, the main goal is to prevent stop times or breakdowns. So, you will need to clearly identify the pain points that can cause equipment failure as well as you should create a schedule of preventative maintenance over regular intervals.

In the end, there should also b taken the time to implement a feedback process that will allow you to continuously track your TPM program effectiveness.

Discover the tips of maintenance under the TPM process.

#7: Implement Specific TPM Concepts As Needed:

One of the things that is always important is to consider your needs before you implement TPM. After all, you may need to optimize the design of new equipment so that it can be easily cleaned and maintained. Besides, in case there are any delays, you will need to find the bottlenecks and implement TPM directly in this area.
