Six sigma implementation can be done in every department. It can be used in production, sales, marketing, design and administration and service. It will also help you to understand your customer\u2019s needs better and more efficiently. It improves performance and delivery and will make great internal improvements. &nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-is-six-sigma\"><strong>What is Six Sigma?<\/strong><\/h3>\n\n\n<p>Six Sigma methodology means 3.4 defects for every one million opportunities. The objective of six sigma implementation is continuous process improvement and produce stable and predictable results. Six Sigma implementation requires the use of tools and techniques to define and evaluate each step of a process or project. It provides methods to improve efficiencies, quality of the process and increase the bottom-line profit.<\/p>\n<p>Six Sigma implementation helps to uplift the performance of manufacturing processes.&nbsp; Six Sigma has a huge potential in improvising buyer satisfaction levels, generating repetitive customers, improving merchandiser performance, improving processes in purchase and inspection, packing and shipping to reduce rejections at later stages. Further, it helps in reducing the business risks.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-history-of-six-sigma\"><strong>History of Six Sigma?<\/strong><\/h3>\n<p><iframe title=\"History Of Six Sigma | Best Lean Six Sigma Black Belt Tutorial For Beginners | @Henry Harvin Six Sigma\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/uTMOm_tbzjM?list=PL28eq_nhJTOdPvRB-4Gb8QfqTufYe4t8e\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n\n\n<p>Six Sigma&nbsp;(6\u03c3) is a set of techniques and tools for process improvement.

Walmart\u2019s vendor management is long-lasting because there is a win-win situation which ensures both the supplier and the buyer benefits. Regular communication and on-time sharing of information with their vendors is a major key to success of Walmart. Walmart has collaborated successfully with its suppliers over years and ensured demand fulfilment timely.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:paragraph \/--><!-- wp:heading {\"level\":3} --><\/p>\n<h3 id=\"h-cross-docking-a-great-strategic-decision\"><strong>Cross-docking \u201ca great strategic decision\u201d<\/strong><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2020\/06\/05130521\/Cross-docking--300x94.png\" alt=\"\" width=\"300\" height=\"94\"><\/p>\n<p><!-- \/wp:heading --><!-- wp:paragraph --><\/p>\n<p>Keeping the low cost of operations helps Walmart in keeping the cost of products low and its benefits for the customers as they have to pay low prices for everyday products. Cross-docking helps Walmart in keeping fewer inventories in stock and spending less cost on warehousing. Directly transferring goods from inbound or outbound trucks or rails and loading them into incoming truck rails and sending them to the stores, eliminating the need for warehousing. This decision leads to bringing down transportation cost, timing, warehousing cost, excess inventory and increases efficiency of the supply chain and inventory management.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:heading {\"level\":3} --><\/p>\n<h3 id=\"h-technology-innovation\"><strong>Technology innovation<\/strong><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2020\/06\/05130545\/Technology-innovation-300x190.png\" alt=\"\" width=\"245\" height=\"155\"><\/p>\n<p><!-- \/wp:heading --><!-- wp:paragraph --><\/p>\n<p>Walmart reached its pinnacle of success by constantly innovating its operations and mechanisms of performing day to day activities. Technology is used by Walmart to predict accurate demand rate of consumers, efficient customer relationship management, keeping a track of the flow of goods along the supply chain, predicting inventory level and correcting and minimizing its errors. Walmart has strategically implemented technology in everyday operations and inventory management. This helps to cut down operating expenses and increase its profit over years. The main technologies used by Walmart to maintain its supply chain management cost effectively are as follows:<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:image {\"align\":\"center\",\"id\":8908,\"sizeSlug\":\"large\"} --><\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/www.henryharvin.com\/blog\/wp-content\/uploads\/2020\/06\/000-1.jpg\" alt=\"\"><\/figure>\n<p><!-- \/wp:image --><!-- wp:paragraph --><\/p>\n<p><strong>Use of Universal Product Code:<\/strong> It brought about a massive change in retail Chain Corporation. These barcodes help to collect and interpret the store level information immediately. This helped in conducting proper operations of business. This helps in keeping track of inventory in the store and process customer demands as well. It added value to Walmart because now the need for manual data entry is eliminated.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:paragraph --><\/p>\n<p><strong>Retail Link:<\/strong> helped Walmart to connect the demand forecasting analysts to the vendor network as well to the center of Walmart\u2019s distribution sites. This is extremely helpful to all the producers and vendors to accurately forecast the consumer\u2019s demand pattern according to historical data which are already and accurately perform the order fulfilment activities via the satellite network.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:paragraph --><\/p>\n<p><strong>RFID (Radio Frequency Identification Tags):<\/strong> After the recent developments that took place in the field of technology, Walmart adopted the use of RFID. Now both the vendors and Walmart can supervise inventory management. This has facilitated the tracking of the flow of goods along the supply chain from distance very easy. It is better than the Bar Codes as it is capable of storing more data than it.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:paragraph --><\/p>\n<p>RFID and smart tags make the operations of Walmart very efficient as timely transfer of information about the stocks in the store track is done and it ensures that none of shelves will be empty and products are provided to customers as and when needed by them. Because of it none of the products go out of stock in any store of Walmart. This helps in bringing down the bullwhip effect and moreover it does not incur the cost of excess inventory.
