areas you need to handle or transform.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">But before you start gathering data, you need the following information first:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Clearly defined goals for data collection,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Purposes for data gathering, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Expected insights.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">It is also necessary to ensure the accuracy of measurements and establish a standardized data collection system.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">You can ensure measurement accuracy by verifying the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Whether the data enables you to achieve your goals,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Whether or not the data needs to be refined, and<\/li>\n\n\n\n<li class=\"translation-block\">Whether you need any additional information.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Also, you can use <a href=\"https:\/\/plaky.com\/learn\/project-management\/what-is-project-management\/\" target=\"_blank\" rel=\"noreferrer noopener\">project management<\/a>

wp-block-paragraph\">Using project management software allows you to organize all your business processes and track how well they\u2019re performing and quickly determine which processes need your attention.<\/p>\n\n\n\n<h3 id=\"principle-3-focus-on-continuous-process-improvement\" class=\"wp-block-heading translation-block\">Principle #3: Focus on continuous process improvement<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Six Sigma methodology is based on the concept of continuous improvement.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">In other words, an organization practicing Six Sigma never stops improving.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Once it has improved one area, it instantly moves to another.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">The goal is to reach the highest possible Sigma level for organizational processes \u2014 the Six Sigma level \u2014 with an accuracy of 99.99966%, while still maintaining other goals and requirements, such as financial stability.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">The closer you are to the Six Sigma level, the better.<\/p>\n\n\n\n<h3 id=\"principle-4-reduce-the-variation\" class=\"wp-block-heading translation-block\">Principle #4: Reduce the variation<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Simply said, variation is a lack of consistency.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Reducing variations improves the process leading to a more consistent customer experience.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Here\u2019s an example to make the variation concept clearer:&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Imagine running a burger bar and having 25 different burgers on the menu.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Your workers must know which ingredient combination goes into each burger and how many ingredients to use.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">With many ingredient options available, there is a higher chance of errors occurring.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">To reduce the variation, you can instruct your employees to use a certain amount of each ingredient for every burger.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Moreover, ingredients should always come from the same suppliers to avoid burgers tasting differently.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">This way, you can ensure consistency in the final product as well as a more consistent customer experience.<\/p>\n\n\n\n<h3 id=\"principle-5-eliminate-waste\" class=\"wp-block-heading translation-block\">Principle #5: Eliminate waste<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Eliminating waste implies removing what\u2019s unnecessary to improve the process outcome, and it may relate to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">People,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Actions, or&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Items.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Simply put, we should remove everything in the process that does not add to the customer\u2019s value.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Eliminating waste reduces:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Costs,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Processing time, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Chances of errors.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">At this point, you might be wondering how exactly are you supposed to know what should be eliminated.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">To answer that question, take a look at the following example.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Imagine running a small pizza place.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">To eliminate waste in your operations, you can ask yourself the following questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><em>Do I need 5 people to put the pizza together and serve it, or can <\/em><em>a single <\/em><em>person prepare a pizza while the others serve the customers?<\/em><\/li>\n\n\n\n<li class=\"translation-block\"><em>How many suppliers do I really need?<\/em><\/li>\n\n\n\n<li class=\"translation-block\"><em>Which pizza options are the most popular?<\/em><\/li>\n\n\n\n<li class=\"translation-block\"><em>Can I optimize the process by including only the best-selling pizzas in the menu and eliminating those nobody ordered in the previous <\/em><em>3 <\/em><em>months?<\/em><\/li>\n\n\n\n<li class=\"translation-block\"><em>How much money do I spend on the ingredients for pizzas that are rarely ordered?<\/em><\/li>\n\n\n\n<li class=\"translation-block\"><em>How much money do I get from the best-selling pizzas compared to other pizza options I currently offer?<\/em><\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">By identifying what is critical for your pizzeria, you will be able to find out what you can eliminate without compromising quality (and gain).<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">\n<div class=\"banner banner-dark plaky-gradient-landing-3\">\n    <div class=\"banner-text lg:pr-[6rem]\">\n        <h2

<\/p>\n\n\n\n<h3 id=\"principle-6-provide-training\" class=\"wp-block-heading translation-block\">Principle #6: Provide training<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">The people on the team need to be trained and have knowledge of the Six Sigma methods of operation.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Forming a <a href=\"https:\/\/pumble.com\/learn\/collaboration\/cross-functional-collaboration\/\" target=\"_blank\" rel=\"noreferrer noopener\">cross-functional team<\/a> consisting of team members with various skills and expertise will help identify any variation.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Experts in different domains can analyze the processes from several angles as well as point out potential defects and discover solutions for them.<\/p>\n\n\n\n<h3 id=\"principle-7-be-flexible\" class=\"wp-block-heading translation-block\">Principle #7: Be flexible<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Six Sigma requires adaptability and having a flexible and responsive system.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Changes will inevitably happen as you eliminate faulty or inefficient processes.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Employees from all departments involved in the process should be able to adapt to these changes easily.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">So, processes should be designed in a way that enables rapid and easy adoption.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">For example, breaking down the processes into steps is a great practice.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">This way, we can apply changes to the step that needs our attention, without having to change or adjust the entire process.<\/p>\n\n\n\n<h3 id=\"principle-8-control-the-process\" class=\"wp-block-heading translation-block\">Principle #8: Control the process<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">As Six Sigma improvements deal with processes that are out of control, the goal is to bring those processes back within the state of statistical control.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">After implementing improvements to your process, you can use certain tools to make sure the process remains in control, e.g.:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Measurements,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Statistics, or<\/li>\n\n\n\n<li class=\"translation-block\">Other Six Sigma tools.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"what-are-the-2-six-sigma-methodologies\" class=\"wp-block-heading translation-block\">What are the 2 Six Sigma methodologies?<\/h2>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">According to <em>Six Sigma: A Complete Step-by-Step Guide<\/em>, Six Sigma teams usually use the following 2 methodologies to make improvements and develop process controls:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><strong>DMAIC <\/strong>(<strong>D<\/strong>efine, <strong>M<\/strong>easure, <strong>A<\/strong>nalyze, <strong>I<\/strong>mprove, and <strong>C<\/strong>ontrol), and<\/li>\n\n\n\n<li class=\"translation-block\"><strong>DMADV<\/strong> (<strong>D<\/strong>efine, <strong>M<\/strong>easure, <strong>A<\/strong>nalyze, <strong>D<\/strong>esign, and <strong>V<\/strong>erify).<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Let\u2019s explain what each methodology entails.<\/p>\n\n\n\n<h3 id=\"approach-1-dmaic\" class=\"wp-block-heading translation-block\">Approach #1: DMAIC<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">DMAIC is a Six Sigma approach to improving company processes, which doesn&#8217;t involve a complete redesign of the processes \u2014 only readjustments.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">DMAIC in Six Sigma incorporates the following 5 phases:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><strong>Define <\/strong>the problem, opportunities for improvement, project goals, and customer requirements,<\/li>\n\n\n\n<li class=\"translation-block\"><strong>Measure <\/strong>how the process performs,<\/li>\n\n\n\n<li class=\"translation-block\"><strong>Analyze <\/strong>the process to determine what causes poor performance (i.e. defects) and identify areas of improvement,<\/li>\n\n\n\n<li class=\"translation-block\"><strong>Improve<\/strong> process performance by addressing and removing the causes of poor performance, and<\/li>\n\n\n\n<li class=\"translation-block\"><strong>Control<\/strong> how the process is implemented in the future.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"686\"

sometimes, fixing or improving a process doesn\u2019t solve the problem, organizations must instead completely replace or redesign processes to achieve desired goals.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">In such cases, when developing a new product, service, or process, organizations may use a modified version of DMAIC called \u2014 DMADV.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">The first 3 process steps of DMADV are similar to DMAIC, however, DMADV\u2019s last 2 steps are oriented toward rolling out and testing a completely new process.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">So, DMADV incorporates the following 5 steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><strong>Define<\/strong> the purpose of a product, service, or project,<\/li>\n\n\n\n<li class=\"translation-block\"><strong>Measure<\/strong> and determine the product,

class=\"translation-block wp-block-paragraph\">Six Sigma has nothing to do with martial arts, though they have a couple of terms in common.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Namely, Six Sigma practitioners hold different color belts corresponding to the ones used in martial arts.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">There are 5 types of Six Sigma certification levels and belts, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Six Sigma White Belt,<\/li>\n\n\n\n<li class=\"translation-block\">Six Sigma Yellow Belt,<\/li>\n\n\n\n<li class=\"translation-block\">Six Sigma Green Belt,<\/li>\n\n\n\n<li class=\"translation-block\">Six Sigma Black Belt, and<\/li>\n\n\n\n<li class=\"translation-block\">Six Sigma Master Black Belt.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">In addition to belts, there are 2 more Six Sigma roles that serve for setting the direction for selecting and deploying projects, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Six Sigma Champions, and<\/li>\n\n\n\n<li class=\"translation-block\">Six Sigma Executives.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Now, let\u2019s analyze the belts and roles in more detail.<\/p>\n\n\n\n<h3 id=\"six-sigma-white-belt\" class=\"wp-block-heading translation-block\">Six Sigma White Belt&nbsp;<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">White Belt holders are those with an elementary level of Six Sigma training.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">A White Belt training is an excellent option for auxiliary staff members as it can help them understand why <a href=\"https:\/\/plaky.com\/learn\/project-management\/project-roles\/\" target=\"_blank\" rel=\"noreferrer noopener\">project teams<\/a> work in a particular way.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">According to the American Society for Quality, White Belts <em>\u201ccan work on local problem-solving teams that support

style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"translation-block wp-block-paragraph\"><strong>Based on <\/strong><strong>the table above<\/strong><strong>, our Sigma level is between 3.90 and 4.<\/strong><\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">That means we can take certain actions to reduce the number of defects and achieve the best-case scenario, i.e. 3.4 DPMO.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Now, let\u2019s calculate the number of defects for the Six Sigma process using the data we have.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\"><strong>Units: <\/strong>580&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\"><strong>Defect opportunities per unit:<\/strong> 3 (size, color, clothing type)<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">At the Six Sigma level, the number of DPMO (defects per million opportunities) is 3.4.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">So, we can calculate the DPO (defects per opportunity) by using the formula for DPMO, as we already know the value for DPMO.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\"><strong>DPMO = 3.4<\/strong><\/p>\n\n\n\n<p class=\"has-background translation-block wp-block-paragraph\" style=\"background-color:#e5f6fe\"><strong>DPMO = DPO x 1,000,000<\/strong><\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">3.4 = DPO x 1,000,000<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">DPO = 3.4 \/ 1,000,000<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">DPO = 0.0000034<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Now, we have the value for DPO, and we can use the formula for DPO to calculate the total number of defects.<\/p>\n\n\n\n<p class=\"has-background translation-block wp-block-paragraph\" style=\"background-color:#e5f6fe\"><strong>DPO = number of defects \/ (number of units x opportunities per unit)<\/strong><\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Defects = (units x opportunities per unit) x DPO<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Defects = (580 x 3) x 0.0000034<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\"><strong>Defects = 0.005916<\/strong><\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Let\u2019s compare our process performance at the current Sigma level to the one at the Six Sigma level.<\/p>\n\n\n\n<figure class=\"wp-block-table responsive\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>Defects per million opportunities at the

class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">As we can see from the table, the number of DPMO is significantly lower at the Six Sigma level than the one we are currently at (between 3.90 and 4).<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">This further means that we might want to use the DMAIC approach to improve the process and try to reach the Six Sigma level.<\/p>\n\n\n\n<h2 id=\"what-are-the-benefits-of-six-sigma\" class=\"wp-block-heading translation-block\">What are the benefits of Six Sigma?<\/h2>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">At this point, we\u2019ll analyze the benefits Six Sigma brings to <a href=\"https:\/\/plaky.com\/learn\/project-management\/what-project-managers-do\/\" target=\"_blank\" rel=\"noreferrer noopener\">project managers<\/a>, including the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Better decision-making,<\/li>\n\n\n\n<li class=\"translation-block\">Less waste,<\/li>\n\n\n\n<li class=\"translation-block\">Improved quality and customer satisfaction,<\/li>\n\n\n\n<li class=\"translation-block\">Decreased operational costs, and<\/li>\n\n\n\n<li class=\"translation-block\">Increased productivity.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Let\u2019s take a closer look at each benefit.<\/p>\n\n\n\n<h3 id=\"benefit-1-better-decision-making\" class=\"wp-block-heading translation-block\">Benefit #1: Better decision-making<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Without proper measurement and analysis, organizations often make bad judgments that lead to poor performance.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">When applying Six Sigma, all decisions are data-driven, so you don\u2019t need to rely on intuition or <a href=\"https:\/\/plaky.com\/blog\/project-assumptions\/\" target=\"_blank\" rel=\"noreferrer noopener\">project assumptions<\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Six Sigma enables better decision-making by relying on data analysis and improving processes based on measurements and metrics.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Having accurate data allows you to make the right choices and find the best solution for process improvement.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Furthermore, using Six Sigma helps organizations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Determine what is wrong,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Validate their assumptions,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Brainstorm potential solutions for problems, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Plan the necessary steps to avoid unwanted consequences.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 id=\"benefit-2-improved-quality-and-customer-satisfaction\" class=\"wp-block-heading translation-block\">Benefit #2: Improved quality and customer satisfaction<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">There is a direct connection between the quality of products and customer satisfaction \u2014 the better your products are, the more satisfied the customers will be.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Six Sigma helps reduce variations and defects, contributing to the better overall quality of products and services.<\/p>\n\n\n\n<h3 id=\"benefit-3-less-waste\" class=\"wp-block-heading translation-block\">Benefit #3: Less waste<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Six Sigma relies on a set of statistical tools to identify and validate a process\u2019 root problem.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">It helps your company optimize processes and decrease total waste.<\/p>\n\n\n\n<h3 id=\"benefit-4-lower-operational-costs\" class=\"wp-block-heading translation-block\">Benefit #4: Lower operational costs<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Organizations often spend extra time fixing defective products and dealing with dissatisfied customers.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">By reducing problems to 3.4 DPMOs, Six Sigma significantly reduces expenses, as defective processes cost you money.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">In other words, an efficient manufacturing process is less expensive, and Six Sigma makes it possible.<\/p>\n\n\n\n<h3 id=\"benefit-5-increased-productivity\" class=\"wp-block-heading translation-block\">Benefit #5: Increased productivity<\/h3>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Applying Six Sigma to your processes boosts efficiency and allows for better <a href=\"https:\/\/plaky.com\/blog\/project-time-management\/\" target=\"_blank\" rel=\"noreferrer noopener\">project time management<\/a>.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">By identifying problematic areas and optimizing your processes, you help your teams operate more efficiently.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">In addition, you avoid having the same problems repeat in the future and eat up your time, as Six Sigma helps you identify their roots.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">\n<div class=\"banner banner-dark plaky-gradient-landing-4\">\n    <div class=\"banner-text lg:pr-[6rem]\">\n

may significantly improve your business processes if you apply it to the right project in the right way<\/h2>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Six Sigma is a data-driven methodology that enables companies to achieve optimal business processes by identifying any weak points and acting on them.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">By focusing on statistics, Six Sigma helps remove defects, reduce variations, and improve productivity, which ultimately leads to reduced costs.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">In addition, Six Sigma emphasizes the value of focusing on customers\u2019 needs with the aim of improving customer satisfaction.<\/p>\n\n\n\n<p class=\"translation-block wp-block-paragraph\">Although Six Sigma to a great extent deals with statistical analysis, it\u2019s important to remember that this methodology isn\u2019t solely about the numbers, but also about the people involved in the process, or as Dr. Kelley explains:&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-columns pro-blockquote is-layout-flex wp-container-core-columns-is-layout-8f761849
