  1. FMEA (Risk priority Number) RPN number is a numerical assessment to evaluate the risk priority level in FMEA analysis. RPN number to help in the prioritize the risk and make a corrective action to mitigation the same. How to calculate the RPN? RPN is calculated by multiplying Severity (S), Occurrence (O) and Detection (D). Score of Severity, Occurrence & Detection is given as per FMEA Index. Severity: - The severity of the failure mode is scored on a scale from 1 to 10 based on risk severity. Occurrence: -The potential of failure occurrence is scored on a
  2. 2 Sample T test 2 sample t test method is a method used to compare the means of two population. We use 2 sample t test when the data of two samples are independent and it is also called independent samples t test. Paired Sample T-Test Paired sample t test is also called dependent sample t test and it is used to determine whether the mean difference between two sets is zero. In a paired sample t test, each entity is measured twice, causing in pair of observation. Commonly uses of paired t test in case control studies or repeated -measured design for example if you
  3. The Process Door and Data Door In DMAIC process, analysis phase is very important phase to analysis the data and there are many tools & techniques which are used for analysing data however some challenges to use right tool & techniques in right situation. Process door and data door are useful to divide the analysis phase into two section which is useful to get the actual analysis. Process Door Process door apply to a section of tools & technique that help to understand and get a clue from process directly. below tools generally use in process door 1.
  4. Curse of Dimensionality: - The term “Curse of dimensionality” used by famous mathematician R. Bellmen in his book Dynamic Programming in 1957. Curse of dimensionality is a problem occur due to adding extra dimensions or attribute in a model. Meaning of Curse of dimensionality is that error increases with increasing the number of features or attributes. Generally, accuracy of any algorithm increases with increase in the number of features or attributes however it is true till threshold limit, after threshold limit algorithm accuracy decreases with increasing the extra num
  5. Block Diagram: Block diagram use to represent process flow diagram, electronic Design, Software design and hardware design, in block diagram main function of process or part are represented with blocks and connected with lines. It uses to make customer or high-level audience understand about the process or drawing with less detail.it is give a quick view of a system to identify the interest or trouble spots. Block diagram give a broad idea of process and not give a minor detail like each pipeline & pumps
  6. Holy Trinity of Project Management Basically, Holy trinity is a ratio of Time, Cost (budget) and Scope of project. In business literature it is called triple constrains. This ratio is important to deliver the successful project – “what is required, within the budget and on time” Project manager can take a decision based on this ratio that project is viable as per customer requirement within the given condition or not. As geometric representation of trinity if we change length of any one then it will impact at least one of other side of tringle
  7. Overall equipment efficiency OEE is the best tool to measuring manufacturing productivity. In simple words it represents the percentage of manufacturing time that is actual productive. Measuring OEE is good practice in industries. We get important insight on how to improve our manufacturing process. OEE is a best matrix for identifying losses benchmarking progress and improving the productivity of manufacturing equipment. Main part of OEE calculation are availability of equipment, Performance of equipment quality of product. OEE = Availability Score × Performance Score × Quality Sco
  8. Quantile Regression: - Linear regression evaluates the mean response of the dependent variable dependent on the independent variables. There are many cases where data is skewed and have outliers when mean do not show the complete pattern of data. Quantile Regression is good alternative of linear regression in the case of skewed data. We can study of distributional relations of variables, heteroscedasticity, dealing with censored variables. We can use Quantile regression to analyze to Major League Base ball salary data at 10%,25%,50%,75% and 90% quantiles. In (Salary) =
  9. Bullwhip Effect Every supply chain has a distribution chain from retailer to manufacture. Goods move from raw materials suppliers to retailer for meeting the customer demand in the distribution chain. Continuous flow of product is important and play a vital role in growing the business in competitive era where many alternative products are available in the market and customer has many choices. Bullwhip effect in supply chain occurs when order of more goods or product than actual demand. The Bullwhip effect follows up in the supply chain its start from retailer, wholesaler, distribut
  10. Fast tracking and Crashing techniques are used in the project management and both techniques have equal importance in the managing of project schedule as per applicability and situations. Fast Tracking: - In this technique project manger perform the project activities parallel instead of series and try to achieve the project timeline. Some risks are involved in the fast-tracking technique because parallel activities might be increased the reworking some time and increase the time. Extra precautions are required when use this technique by the project manager. It is very import
  11. Six Strategies for Fraud Prevention in Your Business Fraud is significantly problem faced by all type of organization. All organization would like to believe that employees are loyal and working for the benefit of the organization (most of them do) Although there are many reasons why employee do fraud. Research shows that the typical organization loses 5% of its annual revenue each year due to fraud. Prevention and detection are important to reducing the loss. Every organization should have a plan in place as preventing fraud is much easier than recovering your losses after fra
  12. Stop The line Philosophy: - Toyota motor corporation’s vehicle production system discovered the thing which are referred in Lean Manufacturing system or “Just In Time” system. Currently these principals are being studying in worldwide. Toyota production system was established based on the many years experience of continuous improvement with the objective of making the vehicles ordered by the customers in fast and efficient ways. This system (TPS) was based on the two concepts 1. Jidoka (Automation with a human touch): - When problem come or identify, the equipment or line stops
  13. Brainstorming: - Brainstorming is technique for generating the idea to solve a problem. Generally, group involves in this technique and thinks under the facilitator, in other word we can say it is group creativity technique. The strength of this technique is that people can think more freely and suggest many spontaneously new ideas. All ideas are noted downed and evaluated post brainstorming session. We must follow below steps during the brainstorming Set a time Focus on problem statements Do not criticism Encourage weird and
  14. Nash Equilibrium: - Nash equilibrium was invented by John Nash an American mathematician. It is a very important concept of game theory. Nash Equilibrium is a decision-making theorem in game theory by which a player can achieve the desired outcome without not disturbing or change in their initial strategy. In Nash equilibrium, each player wins because each player gets their desired outcome. Nash Equilibrium provides a solution concept in a noncooperative game. This theory is used in economics and other disciplines. John Nash got Nobel prize for this w
  15. Median: - Median is a measure of central tendency. We need to arrange the data in order from smallest to largest value for calculating the median, if it is odd number of data then middle value of data would be a median and if there is an even number of data then median is the average of the two middle values. We use the median for measuring the central tendency if data have outliers. For example – if we have data set of (3,13,2,34,11,26,47) and we need to calculate the median then we arrange the data sent from smallest to largest value –(2,3,11,13,26,34,47) . it is an odd number of data s
