chapter 5 process management Flashcards
(7 cards)
Discuss and compare the major elements of lean and Six Sigma.
elements of lean
* Waste reduction
* Lean supply chain relationships
* Lean layouts
* Inventory and set-up time reduction
* Small batch scheduling
* Continuous improvement
* Workforce empowerment.
Six Sigma and lean thinking have many similarities including:
* All products (purchased, WIP and finished goods) must meet or exceed quality requirements
* A culture of continuous improvement must be adopted
ix Sigma Methodology
Define the problem and the goals of the project.
Measure the different aspects of the existing process in detail.
Analyze data to find the main flaw in a process.
Improve the given process.
Control the way the process is implemented in the future.
Describe why lean and Six Sigma are integral parts of SCM.
Lean Six Sigma is crucial for supply chain management because it combines waste reduction (Lean) with variation reduction and process improvement (Six Sigma), leading to increased efficiency, reduced costs, and enhanced quality. This synergy helps businesses become more agile, responsive, and competitive in today’s dynamic market
Discuss the linkage between lean programmes and environmental protection
Lean principles and environmental protection are strongly linked, as Lean focuses on eliminating waste, which naturally extends to environmental waste like materials, energy, and pollution. By improving resource efficiency and reducing unnecessary transportation, Lean practices can lead to a smaller environmental footprint and improved sustainability
Describe and use the various tools of Six Sigma
- flow diagrams. Flow diagrams are also called process diagrams or process maps. Flow diagrams are typically used as the first step to evaluating any manufacturing or service process.
- check sheets.A check sheet is a simple tool to determine frequencies for specific problems.
3.pareto charts.Pareto charts are useful for many applications such as presenting data in an organised fashion and indicating process problems from most to least severe. Pareto charts work well during continuous improvement projects once problems in a process have been identified. - cause and effect diagram.Once a problem has been identified, cause-and-effect diagrams (also called fishbone diagrams or Ishikawa diagrams) can be used to aid in brainstorming and isolating the causes of a problem. The aim of a cause-and-effect diagram is to identify all causes of an effect and then to select the most likely causes that can be investigated further.
- STATISTICAL PROCESS CONTROL.Once a process has been defined, an important next step would be to determine the pattern of variability. Statistical Process Control (SPC) allows organisations to visually monitor process performance and compare this performance to desired levels or standards. Variability can quickly be identified, and corrective steps taken before the process variability gets out of control and damages products, services and customer relationships.
what are the seven types of waste
- Overproducing
- Waiting
- Transportation
- Over processing
- Excess inventory
- Excess movement
- Scrap and rework.
what is six sigma
Six Sigma as “the continuous reduction in process variation to achieve near-flawless quality
what is lean
The concept of lean focuses on the elimination of waste so that supply chains can be faster, more dependable, produce higher quality products and services while at the same time operating at lower cost
