Muda (Waste)
Any activity that consumes resources (including time) but creates no value for the customer. e.g. error corrections, producing MI that is not required.
Waste
Any activity that does not add value, as defined by the customer. A property of the process, not the processor.

TIMWOODS
Acronym for the eight categories of Service waste
Standard Work
Aligning everyone to the same way of working creates a baseline for improvement; these documents can discussed during Sit Ins. -Establishes process step sequence -Clear step-by-step instructions for each activity -Creates a standard to build a CI environment from -Drives good leadership beahviors -Establishes best practices -Focuses on the customer and eliminates waste -Demonstrates whats in it for me
Value Stream
All of the activities required to complete an end-to-end process. Pays attention to internal SLAs/KPIs. Looks at who the typical teams and stakeholders. Evaluates a current performance against purpose. Starts with a customer request and ends when that request has been fulfilled and it includes all of the activities within.
Dissatisfiers
Basic requirements (can be known as must haves) that were expected features or characteristics of a service. If these are not fulfilled, the customer will be extremely unhappy.
William Edwards Deming
Co-founder of the PDCA cycle, was a quality management guru who strived for continuous improvement and creator of the 14 points of TQM
Taachi Ohno
Considered to be the father of the Toyota Production System, which became Lean Manufacturing in the U.S. He devised the seven wastes (or muda in Japanese) as part of this system. He wrote several books about the system.
Huddle boards
Create a forum to review performance, raise issues, and set key objectives around quality, cost, people, and delivery Conducted daily and run for 15 minutes
Sit-Ins
Creates a forum to surface deviations, identify best practices, and to support the development of the new starters (and current team members as well). Consist of manager sitting next to the team member and observing production tasks, using a BEST PRACTICE document when available. Manager spends 30-60 min per person every week and are planned in advance on the visual display/whiteboard. Skills matrix is updated after each session
Service
Deeds, processes, and performances. It includes all economic activities whose output is not a physical product or construction. It is generally consumed at the time it is produced and provides added value in forms that are essentially intangible concerns of it`s first purchaser. -Intangible product -Higher variety in demand type -Instant;short-lived experiences -Cannot be stockpiled -Customer is part of the production -Human element is key to the customer -Fantastic service must follow to compensate for original poor service
Opportunity Demand
Demand that presents a wider opportunity to the business
Failure Demand
Demand which exists due to problems, inaccuracy, confusion, etc., for the customer
Delighters
Excitement requirements-Unexpected features or characteristics that impress customers and earn you "extra credit". Needs are typically unspoken.
Individual Variability
Experienced people are working in different ways to complete the same task / process

Jikoda
This term is often regarded as the forgotten pillar of the Toyota Production system. It speaks about quality at source, or built in quality; no company can survive without excellent quality of product and service and this is the route through which this is achieved. It means JUST IN TIME and can be broken down into the below simple steps: -Discover an abnormality -STOP -Fix the immediate problem -Investigate and correct root cause
Visual management boards
This tool allows one to understand the current situation at a glance, exposes problems, and inspires solutions. Structured approach to ensuring quality, waste reduction, and improvements through the process. Used to display the operational performance of a business area, in as near to real time as possible. Provides visibility of performance to everyone who operates and controls operational activity in that area. Shows what good looks like.
