  1. What is a Block Diagram? A block diagram is a specific, high-level flowchart utilized in engineering, hardware design, electronic design, software design, and process flow diagrams. It is used to design innovative systems or to describe and enhance existing ones. The block diagram represents, at a sketch level, how a process flows from function to function or from unit to unit within an establishment. The diagram uses blocks to reflect the essential activities and links them together by connecting lines representing elements or communication flows. Essential Components of a Block Dia
  2. The Triple Constraint The project management triangle is practiced by project managers to analyze or understand the challenges of implementing and completing a project. Every project, irrespective of its dimension, will have typical constraints. Although there are many such project limitations, these should not be barriers to triumphant project execution and effective decision-making. There are three main interdependent constraints for all projects; time, cost, and scope, also known as the Project Management Triangle, Iron Triangle, Project Triangle, and Holy Trinity. L
  3. The Quality Tools - Interrelationship diagram The purpose of Six Sigma is to improve quality by minimizing variability. In variation reduction, several statistical methods are employed to verify the quality at different project stages. The seven management tools are used primarily for planning and managing are: The activity network diagram (AND), or arrow diagram Affinity diagram (KJ method) Interrelationship diagram Tree diagram Prioritization matrix Matrix diagram Process decision program chart (PDPC) Interrelationship diag
  4. Morphological Matrix Morphological Analysis (MA) is coined by a Swiss-national astrophysicist - Fritz Zwicky. MA is a creative problem-solving technique for systematically structuring and exploring all the possible solutions to a multi-dimensional, complex problem and a powerful tool for generating creative ideas and designing a new product and service. For any significant part of business, success comes from agility and quality of decision-making. Such good decision-making leads to performance enhancements by diminishing rework and driving benefits to the bottom line faster. Lean Six Sig
  5. Dunning Kruger Effect The Dunning Kruger effect is some cognitive bias in which people wrongly exaggerate their understanding or ability in a specific area, which tends to occur because a lack of self-awareness prevents them from accurately assessing their skills. Understanding the Dunning-Kruger Effect The Dunning-Kruger effect concept is based on a 1999 paper by Cornell University psychologists David Dunning and Justin Kruger. The duo tested participants on their logic, grammar, and sense of humor, and found that those who finished in the bottom quartile rated their skill
  6. Johari Window The Johari Window is one of the best-designed communication model used to enhance understanding among individuals within a team or a group. It was coined by American psychologists Joseph Luft & Harry Ingham in the 1950s. The word "Johari" is a combination of Joseph and Harry's first names. Johari Window can further used to improve a group's relationship with other groups. Through disclosure, self-disclosure, and feedback, There are two critical ideas behind the tool: • Individuals can build confidence between themselves by disclosing knowledge about themselves; and

  8. What Is ShuHaRi? The concept of ShuHaRi originates from the Japanese Noh-theater. It is a model practiced to illustrate the pathway a beginner requires to take from each moment someone expresses the interest to study something until that person becomes a master. Though this theory began from the world of theater, it became famous in martial arts. Numerous people still believe today that this is a martial arts technique. + The ShuHaRi principle describes the 3 main stages of learning. Shu, ha, and ri are the various stages of learning. The belief is that each person who embarks t
  9. What is a Box-Cox Transformation? A Box-Cox transformation is a method to remodel non-normal dependent variables into a standard pattern. Normality is a vital hypothesis for many statistical techniques; if the data is not standard, applying a Box-Cox signifies that it can run a broader number of tests. The Box-Cox transformation is coined by two British statisticians, namely George Box and Sir David Roxbee Cox, who researched on a 1964 paper and developed it. Running Box-Cox the Test The essence of the Box-Cox transformation is an exponent, lambda (λ), ranging from -5 to 5. All val
  10. Defect Concentration Diagram Also, know as: check sheet, concentration diagram, location diagram, defect location, defect map Description Statistical process control involves seven essential tools for quality control. One quality control tool is called the defect concentration diagram. A defect concentration diagram is a type of check sheet using an actual image of the object or area where problems could occur. During data collection, observed defects, mistakes, or problems are marked within the picture. When to Use • When we investigate defects, mistakes,
  11. What is the HiPPO Effect? HiPPO, the acronym for the “Highest-Paid Person’s Opinion.” This theory refers to the impact of rank or authority in a meeting where members often fall quiet, admitting, for various reasons, to the view of the person with the absolute power and most distinguished salary. This term is coined by Avinash Kaushik in his book Web Analytics: An Hour a Day. HiPPOs can get within the way of ethical Data-driven decision-making. Having a HiPPO within the meeting room can control an agreement as it often carries a lot more weight than other opinions. Mem
  12. Lean Six Sigma is a process-focused strategy for achieving new levels of performance throughout any company. We need to focus on a process as a system of inputs, activities, and output(s) to provide a holistic way to all the factors and the method they interact together to create value or waste. Many products and services, when used productively, are also processes. An ATM takes account information, personal identification number, and money and processes a transaction that dispenses funds or an account refill. A computer can take inputs, energy, and software to process a Word document. A proce
  13. What is Multicollinearity? Multicollinearity is a known statistical event in which two or more variables in a regression model rely upon the different variables to be linearly predicted from one other with a significant degree of accuracy. It is generally used in observational investigations and less popular in empirical studies. An easy way to understand Multicollinearity is as follows; No Multicollinearity: In the following diagram, we can observe that Xs don't overlap with each other and have a mild correlation with Y. Moderate and Extreme Multicollinearity:
  14. Andon System The origin of the “Andon” word in Japanese comes from the utilization of traditional lighting equipment employing a burning lamp made out of bamboo and paper. This “Andon” idea translated for manufacturing in Japan. The “Andon” became used as a proof to spotlight an anomaly (i.e., a flashing light). This signal would amplify potential defects in quality. When an error was suspected, an indication board would display a sign to the precise workstation having an issue. The signal event would also show that it stopped the system for the defect and expected the matter to be resolved
  15. Queueing Theory Many of us have encountered the frustration of having to await in line. Unfortunately, this experience remains to be popular in crowded, urbanized, “high-tech” environment. We remain in line in our automobiles in traffic jams; we await on-hold for an executive to pick up our phone calls; we wait in line at fast-food joints and we wait in line at outlets to check out. We, as consumers, hardly like these delays, and the organizers of the establishments at which we await also condemn us to wait, since it may yield them business. Why is there awaiting? The
  16. What is a Venn diagram? John Venn who coined the Venn diagram in 1880 was an English mathematician, logician and philosopher. He also called them Euler diagrams after Leonhard Euler, who checked them out a century before. This is an extraordinarily flexible technique of combining circles useful for identify the contrast between overlapping areas of uniqueness. This representation of how groups relate to one another are generally called “sets”. There must be minimum two number of circles, and also the probability of maximum for many uses is 3. However, there can be more shapes
  17. Heijunka is one of the underlying concepts of the Toyota Production System (TPS), shown in below Figure. Levelling any work isn’t easy, but it's the inspiration of Toyota’s celebrated production system. The Japanese coined this idea as Heijunka, extending the concept to include the requirement for ‘standard work’ – the processing of work consistently. The TPS consists of two columns – Jidoka and Just- in-Time both are supported by Heijunka. Heijunka involves production and smoothing processing on using levelling, sequencing and standardising . For a process to run smoo
  18. Kubler-Ross model, involving the following stages: shock, denial, awareness, acceptance, experimentation, search and integration. The below figures illustrate how people typically react to change. Lean Six Sigma projects are about changing things for the better. We’re trying to improve processes–so change is inevitable. Blindly hoping that doing the same things in the same way will magically improve your product or service is head-in-the-sand (HITS) thinking. This is what all the organisations learn from the current pandemic situation.
