Statistical Problem Solving (SPS)

• Statistical Problem Solving

Problem solving in any organization is a problem. Nobody wants to own the responsibility for a problem and that is the reason, when a problem shows up fingers may be pointing at others rather than self.

This is a natural human instinctive defense mechanism and hence cannot hold it against any one. However, it is to be realized the problems in industry are real and cannot be wished away, solution must be sought either by hunch or by scientific methods. Only a systematic disciplined approach for defining and solving problems consistently and effectively reveal the real nature of a problem and the best possible solutions .

A Chinese proverb says, “ it is cheap to do guesswork for solution, but a wrong guess can be very expensive”. This is to emphasize that although occasional success is possible trough hunches gained through long years of experience in doing the same job, but a lasting solution is possible only through scientific methods.

One of the major scientific method for problem solving is through Statistical Problem Solving (SPS) this method is aimed at not only solving problems but may be used for improvement on existing situation. It involves a team armed with process and product knowledge, having willingness to work together as a team, can undertake selection of some statistical methods, have willingness to adhere to principles of economy and willingness to learn along the way.

Statistical Problem Solving (SPS) could be used for process control or product control. In many situations, the product would be customer dictated, tried, tested and standardized in the facility may involve testing at both internal to facility or external to facility may be complex and may require customer approval for changes which could be time consuming and complex. But if the problem warrants then this should be taken up. 

Process controls are lot simpler than product control where SPS may be used effectively for improving profitability of the industry, by reducing costs and possibly eliminating all 7 types of waste through use of Kaizen and lean management techniques.

The following could be used as 7 steps for Statistical Problem Solving (SPS)

• Defining the problem
• Listing variables
• Prioritizing variables
• Evaluating top few variables
• Optimizing variable settings
• Monitor and Measure results
• Reward/Recognize Team members

Defining the problem: Source for defining the problem could be from customer complaints, in-house rejections, observations by team lead or supervisor or QC personnel, levels of waste generated or such similar factors.

Listing and prioritizing variables involves all features associated with the processes. Example temperature, feed and speed of the machine, environmental factors, operator skills etc. It may be difficult to try and find solution for all variables together. Hence most probable variables are to be selected based on collective wisdom and experience of the team attempting to solve the problem.

Collection of data: Most common method in collecting data is the X bar and R charts.  Time is used as the variable in most cases and plotted on X axis, and other variables such as dimensions etc. are plotted graphically as shown in example below.

Once data is collected based on probable list of variables, then the data is brought to the attention of the team for brainstorming on what variables are to be controlled and how solution could be obtained. In other words , optimizing variables settings . Based on the brainstorming session process control variables are evaluated using popular techniques like “5 why”, “8D”, “Pareto Analysis”, “Ishikawa diagram”, “Histogram” etc. The techniques are used to limit variables and design the experiments and collect data again. Values of variables are identified from data which shows improvement. This would lead to narrowing down the variables and modify the processes, to achieve improvement continually. The solutions suggested are to be implemented and results are to be recorded. This data is to be measured at varying intervals to see the status of implementation and the progress of improvement is to be monitored till the suggested improvements become normal routine. When results indicate resolution of problem and the rsults are consistent then Team memebres are to be rewarded and recognized to keep up their morale for future projects.

Who Should Pursue SPS

• Statistical Problem Solving can be pursued by a senior leadership group for example group of quality executives meeting weekly to review quality issues, identify opportunities for costs saving and generate ideas for working smarter across the divisions
• Statistical Problem solving can equally be pursued by a staff work group within an institution that possesses a diversity of experience that can gather data on various product features and tabulate them statistically for drawing conclusions
• The staff work group proposes methods for rethinking and reworking models of collaboration and consultation at the facility
• The senior leadership group and staff work group work in partnership with university faculty and staff to identify research communications and solve problems across the organization

Benefits of Statistical Problem Solving

• Long term commitment to organizations and companies to work smarter.
• Reduces costs, enhances services and increases revenues.
• Mitigating the impact of budget reductions while at the same time reducing operational costs.
• Improving operations and processes, resulting in a more efficient, less redundant organization.
• Promotion of entrepreneurship intelligence, risk taking corporations and engagement across interactions with business and community partners.
• A culture change in a way a business or organization collaborates both internally and externally.
• Identification and solving of problems.
• Helps to repetition of problems
• Meets the mandatory requirement for using scientific methods for problem solving
• Savings in revenue by reducing quality costs
• Ultimate improvement in Bottom -Line
• Improvement in teamwork and morale in working
• Improvement in overall problem solving instead of harping on accountability

Business Impact

• Scientific data backed up problem solving techniques puts the business at higher pedestal in the eyes of the customer.
• Eradication of over consulting within businesses and organizations which may become a pitfall especially where it affects speed of information.
• Eradication of blame game

QSE’s Approach to Statistical Problem Solving

By leveraging vast experience, it has, QSE organizes the entire implementation process for Statistical Problem Solving in to Seven simple steps

• Define the Problem
• List Suspect Variables
• Prioritize Selected Variables
• Evaluate Critical Variables
• Optimize Critical Variables
• Monitor and Measure Results
• Reward/Recognize Team Members
• Define the Problem (Vital Few -Trivial Many):

List All the problems which may be hindering Operational Excellence . Place them in a Histogram under as many categories as required.

Select Problems based on a simple principle of Vital Few that is select few problems which contribute to most deficiencies within the facility

QSE advises on how to Use X and R Charts to gather process data.

• List Suspect Variables:

QSE Advises on how to gather data for the suspect variables involving cross functional teams and available past data

• Prioritize Selected Variables Using Cause and Effect Analysis:

QSE helps organizations to come up prioritization of select variables that are creating the problem and the effect that are caused by them. The details of this exercise are to be represented in the Fishbone Diagram or Ishikawa Diagram

• Evaluate Critical Variables:

Use Brain Storming method to use critical variables for collecting process data and Incremental Improvement for each selected critical variable

QSE with its vast experiences guides and conducts brain storming sessions in the facility to identify KAIZEN (Small Incremental projects) to bring in improvements. Create a bench mark to be achieved through the suggested improvement projects

• Optimize Critical Variable Through Implementing the Incremental Improvements:

QSE helps facilities to implement incremental improvements and gather data to see the results of the efforts in improvements

• Monitor and Measure to Collect Data on Consolidated incremental achievements :

Consolidate and make the major change incorporating all incremental improvements and then gather data again to see if the benchmarks have been reached

QSE educates and assists the teams on how these can be done in a scientific manner using lean and six sigma techniques

QSE organizes verification of Data to compare the results from the original results at the start of the projects. Verify if the suggestions incorporated are repeatable for same or better results as planned

              Validate the improvement project by multiple repetitions

• Reward and Recognize Team Members:

QSE will provide all kinds of support in identifying the great contributors to the success of the projects and make recommendation to the Management to recognize the efforts in a manner which befits the organization to keep up the morale of the contributors.

The Six Sigma Approach: A Data-Driven Approach To Problem-Solving

If you are a project manager or an engineer, you may have heard of the  6 Sigma approach to problem-solving by now. In online Six Sigma courses that teach the Six Sigma principles , you will learn that a data-driven approach to problem-solving , or the Six Sigma approach, is a better way to approach problems. If you have a Six Sigma Green Belt certification then you will be able to turn practical problems into practical solutions using only facts and data.

Attend our 100% Online & Self-Paced Free Six Sigma Training .

This approach does not have room for gut feel or jumping to conclusions. However, if you are reading this article, you are probably still curious about the Six Sigma approach to problem-solving.

What is the Six Sigma Approach?

Let’s see what the Six Sigma approach or thinking is. As briefly described in free Six Sigma Green Belt Certification training , this approach is abbreviated as DMAIC. The DMAIC methodology of Six Sigma states that all processes can be Defined, Measured, Analyzed, Improved and Controlled . These are the phases in this approach. Collectively, it is called as DMAIC. Every Six Sigma project goes through these five stages. In the Define phase, the problem is looked at from several perspectives to identify the scope of the problem. All possible inputs in the process that may be causing the problem are compared and the critical few are identified. These inputs are Measured and Analyzed to determine whether they are the root cause of the problem. Once the root cause has been identified, the problem can be fixed or Improved. After the process has been improved, it must be controlled to ensure that the problem has been fixed in the long-term.

Check our Six Sigma Training Video

Every output (y) is a function of one or multiple inputs (x)

Any process which has inputs (X), and delivers outputs (Y) comes under the purview of the Six Sigma approach. X may represent an input, cause or problem, and Y may represent output, effect or symptom . We can say here that controlling inputs will control outputs. Because the output Y will be generated based on the inputs X.

This Six Sigma approach is called Y=f(X) thinking. It is the mechanism of the Six Sigma. Every problematic situation has to be converted into this equation. It may look difficult but it is just a new way of looking at the problem.

Please remember that the context of relating X and Y to each other would vary from situation to situation. If X is your input, then only Y becomes your output. If X is your cause, Y will not be regarded as the output. If X is your input, Y cannot be called as an effect.

Let’s go further. The equation of Y=f(X) could involve several subordinate outputs, perhaps as leading indicators of the overall “Big Y.” For example, if TAT was identified as the Big Y, the improvement team may examine leading indicators, such as Cycle Time; Lead Time as little Ys. Each subordinate Y may flow down into its own Y= f(X) relationship wherein some of the critical variables for one also may affect another little Y. That another little variable could be your potential X or critical X.

A practical vs. a statistical problem and solution

In the Six Sigma approach, the practical problem is the problem or pain area which has been persisting on your production or shop floor. You will need to c onvert this practical problem into a statistical problem. A statistical problem is the problem that is addressed with facts and data analysis methods. Just a reminder, the measurement, and analysis of a statistical problem is completed in Measure and Analyze phase of the Six Sigma approach or DMAIC.

In this approach, the statistical problem will then be converted into a statistical solution. It is the solution with a known confidence or risk levels versus an “I think” solution. This solution is not based on gut feeling. It’s a completely data-driven solution because it was found using the Six Sigma approach.

A Six Sigma approach of DMAIC project would assist you to convert your Practical Problem into Statistical Problem and then your Statistical Problem into Statistical Solution. The same project would also give you the Practical Solutions that aren’t complex and too difficult to implement. That’s how the Six Sigma approach works.

This approach may seem like a lot of work. Wouldn’t it be better to guess what the problem is and work on it from there? That would certainly be easier, but consider that randomly choosing a root cause of a problem may lead to hard work that doesn’t solve the problem permanently. You may be working to create a solution that will only fix 10% of the problem while following the Six Sigma approach will help you to identify the true root cause of the problem . Using this data-driven Six Sigma approach, you will only have to go through the problem-solving process once.

The Six Sigma approach is a truly powerful problem-solving tool. By working from a practical problem to a statistical problem, a statistical solution and finally a practical solution, you will be assured that you have identified the correct root cause of the problem which affects the quality of your products. The Six Sigma approach follows a standard approach – DMAIC – that helps the problem-solver to convert the practical problem into a practical solution based on facts and data . It’s very important to note that the Six Sigma approach is not a one-man show. Problem solving should be approached as a team with subject matter experts and decicion makers involved.

This one-day seminar provides training on the seven statistical tools. These tools are used in problem solving and continual improvement endeavors. The seven statistical tools were first introduced by Dr. Ishikawa when he introduced problem solving in Japan. Dr. Ishikawa put together seven simple tools that were already available for use. While the entire tool set is not named after him, the cause and effect diagram or the fishbone diagram which has been attributed to his creation has often been also called the “Ishikawa” diagram. When using the seven statistical tools, it is always good to remember Dr. Ishikawa’s words to those doing improvement – “speak with data”. Omnex teaches this course as a standalone one day or in conjunction with our problem solving courses.

Using Statistics to Improve Problem Solving Skills

Problem-solving is an essential skill that everyone must possess, and statistics is a powerful tool that can be used to help solve problems. Statistics uses probability theory as its base and has a rich assortment of submethods, such as probability theory, correlation analysis, estimation theory, sampling theory, hypothesis testing, least squares fitting, chi-square testing, and specific distributions.

Each of these submethods has its unique set of advantages and disadvantages, so it is essential to understand the strengths and weaknesses of each method when attempting to solve a problem.

Introduction

Overview of Problem-Solving

Role of statistics in problem-solving, probability theory, correlation analysis.

Introduction: Problem-solving is a fundamental part of life and an essential skill everyone must possess. It is an integral part of the learning process and is used in various situations. When faced with a problem, it is essential to have the necessary tools and knowledge to identify and solve it. Statistics is one such tool that can be used to help solve problems.

Problem-solving is the process of identifying and finding solutions to a problem. It involves understanding the problem, analyzing the available information, and coming up with a practical and effective solution. Problem-solving is used in various fields, including business, engineering, science, and mathematics.

Statistics is a powerful tool that can be used to help solve problems. Statistics uses probability theory as its base, so when your problem can be stated as a probability, you can reliably go to statistics as an approach. Statistics, as a discipline, has a rich assortment of submethods, such as probability theory, correlation analysis, estimation theory, sampling theory, hypothesis testing, least squares fitting, chi-square testing, and specific distributions (e.g., Poisson, Binomial, etc.).

Probability theory is the mathematical study of chance. It is used to analyze the likelihood of an event occurring. Probability theory is used to determine the likelihood of an event, such as the probability of a coin landing heads up or a certain number being drawn in a lottery. Probability theory is used in various fields, including finance, economics, and engineering.

Correlation analysis is used to determine the relationship between two variables. It is used to identify the strength of the relationship between two variables, such as the correlation between the temperature and the amount of rainfall. Correlation analysis is used in various fields, including economics, finance, and psychology.

Estimation Theory

Estimation theory is used to estimate the value of a variable based on a set of data. It is used to estimate the value of a variable, such as a city's population, based on a sample of the population. Estimation theory is used in various fields, including economics, finance, and engineering.

Conclusion: Statistics is a powerful tool that can be used to help solve problems. Statistics uses probability theory as its base, so when your problem can be stated as a probability, you can reliably go to statistics as an approach.

Statistics are the key to unlocking better problem-solving skills - the more you know, the more you can do. IIENSTITU

What role does probability theory play in using statistics to improve problem solving skills?

Probability theory and statistics are both essential tools for problem-solving, and the two disciplines share an interdependent solid relationship. This article will discuss the role that probability theory plays in using statistics to improve problem-solving skills.

Probability theory provides a framework for understanding the behavior of random variables and their associated distributions. We can use statistics to make better predictions and decisions by understanding and applying probability theory. For example, when calculating the probability of a desired outcome, we can use statistical methods to determine the likelihood of that outcome occurring. This can be used to inform decisions and help us optimize our strategies.

Statistics also provide us with powerful tools for understanding the relationship between variables. By analyzing the correlation between two or more variables, we can gain valuable insights into the underlying causes and effects of a problem. For example, by studying a correlation between two variables, we can determine which variable is more likely to cause a particular outcome. This can help us to design more effective solutions to problems.

By combining probability theory and statistics, we can develop powerful strategies for problem-solving. Probability theory helps us understand a problem's underlying structure, while statistics provide us with the tools to analyze the data and make better predictions. By understanding how to use these two disciplines together, we can develop more effective solutions to difficult problems.

In conclusion, probability theory and statistics are both essential for problem-solving. Probability theory provides a framework for understanding the behavior of random variables, while statistics provide powerful tools for understanding the relationships between variables. By combining the two disciplines, we can develop more effective strategies for solving complex problems.

How can correlation analysis be used to identify relationships between variables when solving problems?

Correlation analysis is a powerful tool for identifying relationships between variables when solving problems. It is a statistical approach that measures how two variables are related. By analyzing the correlation between two variables, researchers can identify the strength and direction of their relationship. For example, a correlation analysis can determine if a change in one variable is associated with a change in the other.

When conducting correlation analysis, researchers often use Pearson’s correlation coefficient (r) to measure the strength of the association between two variables. This coefficient ranges from -1 to +1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and +1 indicates a perfect positive correlation. A perfect positive correlation indicates that when one variable increases, the other variable also increases, and a perfect negative correlation indicates that when one variable increases, the other variable decreases.

Correlation analysis helps identify relationships between variables when solving problems. For example, in a study of the relationship between dietary habits and body weight, a researcher may use correlation analysis to determine if there is a relationship between the two variables. Suppose the researcher finds a significant correlation between dietary habits and body weight. In that case, this can provide insight into the studied problem and help inform solutions.

Correlation analysis can also be used to identify causal relationships between variables. By examining the relationship between two variables over time, researchers can determine if a change in one variable is associated with a change in the other. For example, a researcher may use correlation analysis to determine if temperature changes are associated with changes in air quality. If a significant correlation is found, then the researcher can conclude that temperature changes are likely causing changes in air quality.

Overall, correlation analysis is a powerful tool for identifying relationships between variables when solving problems. By examining the strength and direction of the relationship between two variables, researchers can gain insight into the problem being studied and inform potential solutions.

What are the benefits of using estimation theory when attempting to solve complex problems?

Estimation theory is a powerful tool when attempting to solve complex problems. This theory involves making educated guesses or estimations about the value of a quantity that is difficult or impossible to measure directly. By utilizing estimation theory, one can reduce uncertainty and make decisions more confidently.

The main benefit of using estimation theory is that it allows for the quantification of uncertainty. By estimating, one can determine the range of possible outcomes and make decisions based on the likelihood of each outcome. This helps to reduce the risks associated with making decisions as it allows one to make better decisions based on the available data.

Another benefit of using estimation theory is that it can be applied to many problems. Estimation theory can be used to solve problems in fields such as engineering, finance, and economics. It can also be used to estimate a stock's value, the project's cost, or the probability of a certain event. Estimation theory is also useful in predicting the behavior of a system over time.

Estimation theory can also be used to make decisions in cases where the data is limited. By estimating, one can reduce the amount of data needed to make a decision and make more informed decisions. Furthermore, estimation theory can be used to make decisions even when the data is incomplete or inaccurate. This is especially useful when making decisions in situations where the data is uncertain or incomplete.

In conclusion, estimation theory is a powerful tool for solving complex problems. It can be used to reduce uncertainty, make decisions in cases where data is limited or incomplete, and make predictions about the behavior of a system over time. By utilizing estimation theory, one can make more informed decisions and reduce the risks associated.

How does the application of statistical methods contribute to effective problem-solving in various fields?

**Statistical Methods in Problem-solving** Statistical methods play a crucial role in effective problem-solving across various fields, including natural and social sciences, economics, and engineering. One primary contribution lies in the quantification and analysis of data. **Data Quantification and Analysis** Through descriptive statistics, researchers can summarize, organize, and simplify large data sets, enabling them to extract essential features and identify patterns. In turn, this fosters a deeper understanding of complex issues and aids in data-driven decision-making. **Prediction and Forecasting** Statistical methods can help predict future trends and potential outcomes with a certain level of confidence by extrapolating obtained data. Such prediction models are invaluable in fields as diverse as finance, healthcare, and environmental science, enabling key stakeholders to take proactive measures. **Hypothesis Testing** In the scientific process, hypothesis testing enables practitioners to make inferences about populations based on sample data. By adopting rigorous statistical methods, researchers can determine the likelihood of observed results occurring randomly or due to a specific relationship, thus validating or refuting hypotheses. **Quality Control and Improvement** In industries and manufacturing, statistical methods are applied in quality control measures to ensure that products and services meet established standards consistently.
