8 Valuable Lean and Six Sigma Tools To Try
Six Sigma may be a business management methodology that leverages a scientific approach to quality measurement with the aim of reducing variation and defects. the strategy was pioneered by Motorola and Allied Signal so made famous by GE who boasted $10 billion in savings during the primary years of implementation. Lean is another methodology, doctrine, tool set, and management system that also uses a objective problem solving approach, and more. "Lean" may be a generic term that was given to the Toyota Production System, or TPS. the 2 pillars of TPS are usually described as "just in time flow" and "quality at the source." Lean and 6 Sigma are often used together by organizations in multiple industries, bringing methods and attitude from each approach. Many frameworks exist for implementing the methodologies. Many of these tools will be useful to organizations whether or not they fully embrace the Lean or Six Sigma access. Here are some that our customers have found Most worthy.
The 5 Whys
While we’re talking about Lean tools that involve the amount five, we should always mention the 5 Whys. detain mind that one in every of the essential tenets of Lean is that problems should be addressed at the basis cause instead of covered up or worked around. The elemental explanation for a problem can often be found by asking the categorical question, “Why?” five times. the solution to every question is documented, and also the process is repeated until the source of the difficulty is identified and resolved.
A3 reports (named after the metric paper size initially employed by Toyota) are one-page reports that document everything that's necessary for deciding and reporting for a specific process. they're accustomed condense information from many sources into one easily digestible and actionable document. They typically include background, the present process flow, analysis, goals, recommendations, and an implementation plan.
Control charts are accustomed visualize the outputs of a process over time. Control charts are a technique that predate the terms Lean and 6 Sigma and are sometimes related to either method. they often have upper and lower control limits that are each three deviations from the mean. Control charts help managers recognize common cause variation, which indicates the method has not changed, and special cause variation, which indicates a controversy or a shift within the process or system. Control charts represent the baseline upon which improvement will be initiated.
DMAIC stands for Define, Measure, Analyze, Improve, and control. it's perhaps the foremost important Six Sigma tool of all. it's an improvement cycle that's accustomed stabilize, improve, and optimize business processes. Many discuss with DMAIC because the Six Sigma roadmap for problem-solving. Once the cycle is completed, and new Standard Work is documented, it will be repeated to realize additional improvement.
Kanban means “shop keeper’s sign” in Japanese. it's a visualization methodology that enables for just-in-time manufacturing and streamlined workflow in other industries. the thought is to use visual cues to deliver the right inputs a process needs when it needs them. this suggests that stock levels of raw materials, components, add progress and finished goods will be kept to a minimum. Today, many organizations use digital Kanban boards to visualise the movement of labor current through a process.
It's often said that of the first goals of Six Sigma is that the elimination of variation, but Lean focuses thereon goal, as well. to realize consistent, predictable results, it's imperative that every process is performed the identical way on every occasion, no matter who is completing the associated tasks. this can be achieved through the event, documentation, and enforcement of normal Work. the quality represents the present best practice for performing each a part of the method. the quality Work isn't set in stone, however. It represents the baseline upon which improvement measured.
Value Stream Mapping
Value stream mapping may be a Lean tool designed to confirm that each a part of a process delivers value to the customer. Value is defined as something that the customer is willing to obtain. During the worth stream mapping exercise, the present process is documented. Every step, task, or resource expenditure that doesn't directly produce value is targeted for elimination or improvement.
These Lean and 6 Sigma tools will be used independently or together to realize quantitative business goals. Improvement management software is usually expand to unify improvement projects using these capability and to magnify the results. Our clients who’ve made use of those tools have reported measurable leads to terms of cost savings, quality improvement, increased customer satisfaction, and employee engagement.
