Downtime stands for:
Defects.
Overproduction.
Waiting.
Not utilizing talent.
Transportation.
Inventory excess.
Motion waste.
Excess processing.
Also to know is, what is the definition of lean manufacturing?
Lean manufacturing or lean production, often simply “lean”, is a systematic method for waste minimization (“Muda”) within a manufacturing system without sacrificing productivity. Lean also takes into account waste created through overburden (“Muri”) and waste created through unevenness in work loads (“Mura”).
What are the concepts of lean?
Lean manufacturing includes a set of principles that lean thinkers use to achieve improvements in productivity, quality, and lead-time by eliminating waste through kaizen. Kaizen is a Japanese word that essentially means “change for the better” or “good change.”
What is the lean manufacturing process?
Simply, lean means creating more value for customers with fewer resources. A lean organization understands customer value and focuses its key processes to continuously increase it. The ultimate goal is to provide perfect value to the customer through a perfect value creation process that has zero waste.
What are the 8 Wastes of lean manufacturing?
The 8 wastes of lean manufacturing include:
Defects. One of the most easily recognizable wastes in lean manufacturing is the production of Defects.
Excess Processing.
Overproduction.
Waiting.
Inventory.
Moving.
Motion.
Non-Utilized Talent.
What are the 5 S stands for?
5S stands for sort, set in order, shine, standardize and sustain. By: Kevin Mehok. Thursday, September 1, 2011 – 00:00.
What are the 5 wastes?
The Seven Wastes of Lean Manufacturing are;
Transport.
Inventory.
Motion.
Waiting.
Over-Processing.
Overproduction.
Defects.
Who introduced Six Sigma?
Six Sigma (6σ) is a set of techniques and tools for process improvement. It was introduced by engineer Bill Smith while working at Motorola in 1986. Jack Welch made it central to his business strategy at General Electric in 1995.
What is value stream in Six Sigma?
Value Stream Mapping. Value stream mapping is typically used in Lean, it differs from the process mapping of Six Sigma in four ways: 1) It gathers and displays a far broader range of information than a typical process map. 2) It tends to be at a higher level (5-10 boxes) than many process maps.
What is waste motion?
Motion Waste. The waste of motion is one of the seven wastes attributed to Taiichi Ohno, the father of modern Lean. Walking to printers and fax machines, excessive clicking, or searching for supplies in a messy cabinet are all examples of wasted motion.
What is a process waste?
Waste is any step or action in a process that is not required to complete a process (called “Non Value-Adding”) successfully. When Waste is removed, only the steps that are required (called “Value-Adding”) to deliver a satisfactory product or service to the customer remain in the process.
What is the meaning of yield in Six Sigma?
Throughput Yield is a Lean Six Sigma metric indicating the ability of the process to produce defect-free units. The Throughput Yield (Yt) is calculated using the Defects per Unit (DPU).
What is lean waste?
Lean manufacturing or lean production, often simply “lean”, is a systematic method for waste minimization (“Muda”) within a manufacturing system without sacrificing productivity. Lean also takes into account waste created through overburden (“Muri”) and waste created through unevenness in work loads (“Mura”).
How many Sigmas can be fit between UCL and LCL?
The Upper Control Limit (UCL) is set three sigma levels above the mean and the Lower Control Limit (LCL) is set at three sigma levels below mean.
What is a stable process?
Process Stability refers to the consistency of the process with respect to important process characteristics such as the average value of a key dimension or the variation in that key dimension. If the process behaves consistently over time, then we say that the process is stable or in control.
What is the lean method?
A lean organization understands customer value and focuses its key processes to continuously increase it. The ultimate goal is to provide perfect value to the customer through a perfect value creation process that has zero waste.
What are the fundamental elements of lean?
There are five basic principles of lean thinking highlighted by Womack and Jones.
Value. Every company needs to understand what value the customer places upon their products and services.
The Value Stream.
Flow.
Pull.
Perfection.
What are the 7 types of waste?
The seven wastes consist of:
Overproduction. Simply put, overproduction is to manufacture an item before it is actually required.
Waiting. Whenever goods are not moving or being processed, the waste of waiting occurs.
Transporting.
Inappropriate Processing.
Unnecessary Inventory.
Unnecessary / Excess Motion.
Defects.
How is the Lean Six Sigma Dmaic process?
DMAIC is the problem-solving methodology behind Lean Six Sigma. It consists of five Phases: Define, Measure, Analyze, Improve and Control. It is pronounced “duh-may-ik”.
What is Six Sigma quality?
Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process – from manufacturing to transactional and from product to service.
What is waste of transportation?
Transportation waste is the unnecessary movement of parts, double-handling of materials, or shuffling of inventory to get access to the right components. Transportation waste is one of the seven wastes that Taiichi Ohno identified as barriers to flow. It is obvious why moving parts further than necessary is wasteful.
What is downtime in lean methodology?
Having used the DOWNTIME acronym for the 8 forms of waste (defects, overproduction, waiting, not utilizing staff talent, travel, inventory, motion, excess processing) I am curious as to who originally developed this acronym.
How does Lean Manufacturing eliminate waste?
Each operation will benefit from lean in unique ways, but here are four common ways lean can help decrease warehouse waste:
Reduce waste caused by excess inventory and over-production.
Minimize labor expenditures related to unnecessary motion.
Decrease transportation-related waste.
Reduce over-processing waste.
