Goal Statement
Define; States the desired results of a process improvement project; Written with focus on measurable goals and should not touch on causes or solutions
In Scope v. Out of Scope
Define; You want the scope to be broad enough to achieve the project objectives yet narrow enough to be completed within the project plan timeframe
SIPOC
Define; Supplier-Inputs-Process-Outputs-Customers; Helps teams verify that process inputs match outputs of the upstream process and inputs/expectations of downstream processes
Kano Analysis
Define; Helps you understand what value your customers place on features of your product or service, which can reduce the risk of missing critical-to-quality features
Dissatisfier
Basic requirement; if these needs/features are not fulfilled then customers will be extremely upset
Satisfier
Performance requirements; standard characteristics that increase or decrease satisfaction by the degree
Delighter
Excitement requirements; unexpected features that impress customers and earn you extra credit
CTQ Tree
Define; The key measurable characteristics of a product or process whose performance standards or specification limits must be met in order to satisfy the customer. They align improvement or design efforts with customer requirements
Affinity Diagram
Define; A way to organize facts, opinions, and issues into natural groups to help diagnose a complex situation of find themes; Stick notes are good to use for this
Process Map
Measure; Captures steps within a process and how it flows from start to finish; Many different types; Visual representation of what gets done in certain process
Swim Lane Map
Measure; Tracks a process from beginning to end and puts each process step in a lane; each lane represents an individual person, department, etc.
VSM
Measure; A process map with data; A tool for capturing process data as well as flow; Captures important process metrics
Spaghetti Diagram
Measure; A visual representation using a continuous flow line; Depicts the physical flow of work or material in a process; Used to improve layout of a workspace
Operator Machine Charts
Measure; Graphically represents the relationship between the manual work performed and the machines involved in the different process steps
Continuous Data
Any variable measured on a continuum scale that can be infinitely divided (lead time, cost, etc.)
Attribute/Discrete Data
All other data that is not continuous (count, binary, nominal, ordinal)
Nominal Data
Attribute Data; names or labels
Ordinal Data
Attribute Data; names or labels that represent a value inherent to the object or item
Rule of 10's
The resolution of your data should fit 10 times into the process variation you are measuring (resolution/range > 10)
Measurement System Analysis (MSA)
Measure; Used to determine if measurement system can generate accurate data, and if accuracy is adequate to achieve your objectives; Measurements need to be both PRECISE and ACCURATE
Gage R&R
Measure; Continuous Data; Involves evaluating the repeatability (dealing with the measurement system) and reproducibility (dealing with operator of measurement system) of a measurement system
Kappa Calculations
Measure; Attribute Data; used to check f [Show Less]
