Optimize process, do what the custmer will pay for, TPS, cross training helps improve workflow (assembly line), 7 types odf waste, transport, movement, waiting,
inventory: only store what you need, keep daily supplies, restock at the end of the day
waiting: inform supervisor of delays and lack of work in your area, use time to cross train
defects: be slow and meticulous while working to not scrap the part/operation
transport: move parts after completing process, take more than one job at a time, move minimum distance
motion: locate tools you need and move them near your workplace
overproduction: only make what you'll sell and no more
over-processng: always meet quality requirements, don't go above requirements
See something say something, if you have an idea talk to a supervisor, lean ranges from small projects to large events
The 6S' are an important part of LEAN because it gives you a guide to follow when using LEAN in the workplace.
Lean is a workplace process that helps make workflow more efficient and less wasteful, it gives everyday steps to follow to be more efficient and meet the needed quotas.
There are 2 different types of lean, one is people-centric and the other is profit-centric. People centric is focusing on bettering the process based on people the profit-centric is focusing on bettering the process for making more of a profit.
LEAN is the first step to adding automation.
My experience with lean is in the workplace of my summer job. They didn't have much experience with lean, most paperwork and some of the rooms were cramped and messy. I was tasked with making gift boxes for customers but the room I was in was very cluttered and disorganized, I spent a lot of time making sure I had all the snacks/drinks I needed to put in the boxes within arms length of me so that I could get as many boxes as I could done. I had someone checking on me and getting me things when I needed them but instead of telling them when I ran out of something I would tell them a little before so that they had time to get the materials for me and by the time they got back to me I would only have a couple left. My attempts didn't go unnoticed, they ended up tasking me to reorganize the room, in the end I made the room and the products inside the room easier for everyone to access and making the process of building boxes easier.
Kaizen- continuous improvement, more of a mindset, to follow this means to never be satisfied with how things are in the workplace
MUDA(waste)- every process element that does not create value to product- defects, excessive inventory, process, unnecessary motion, overproduction, waiting, transportation
MURA(unevenness)- fluctuation, imbalance of workload, capacity or workflow
MURI(overburden)- pushing machine/operator beyond their limits, creates quality problems
The house of lean is a simplification of the different houses of lean. It showcases the technical side, the social side, leadership principals, in simplar terms the house of lean is a organization of the different types of lean.
Kaizen is the mindset of continuous improvement. The kaizen mindset is important to have in the workplace because it makes sure there's always someone looking for things to improve.
The 3M's are MUDA, MURA, and MURI. These are important because they all represent different things, MUDA represents waste, MURA represents unevenness in the workflow, and MURI represents overburden.
8 types of waste: defects/missing/incorrect information, overproduction, waiting, non-standard processing, transportation, intellect, motion, and excess inventory.
Waste is whatever doesn't add value to the customer. Examples of NVA are excessive packaging, setting up equipment, inspecting a part, billing a customer
Can trace overproduction back to the types of waste.
Identify what bugs you and improve it.
Common symptoms of waste:
overproduction: delays/disruptions of process, quality issues
transportaton: increased inventory, hanling, costs
inventory: excess things taking up storage space
waiting: increased lead times since process takes longer to complete, reduced efficiency
human potential: reduced engagement, reduced
