LSS Fundamentals
This methodology aids the achievement of corporate strategies and objectives by combining Lean and Six Sigma principles.
What is Lean Six Sigma?
This acronym stands for Define, Measure, Analyze, Improve, Control.
What is DMAIC?
This plan provides a clear, documented strategy for collecting reliable data and ensures data answers the right questions.
What is a Data Collection Plan?
This high-level process map includes customers, outputs, process steps, inputs, and suppliers.
What is theSIPOC?
This diagram creates a structured list of possible causes of a problem.
What is a Cause-and-Effect Diagram?
This acronym stands for Specific, Measurable, Achievable, Realistic, Time-bounded.
What is SMART?
In this phase, potential root causes are identified.
What is the Analyze phase?
Understanding whether data is continuous or discrete is important because different tools can only be used on the right type of data.
What is data space?
This creates a shared view of the process, provides a structure for root cause analysis, and identifies what is actually going on.
What is a process map?
Root causes are validated in this phase of the DMAIC process.
What is the Analyze phase?
This term represents a defect level of 3.4 DPMO.
What is Six Sigma?
Solutions are developed in this phase of the DMAIC process.
What is the Improve phase?
This phase involves establishing a process performance baseline.
What is the Measure phase?
The as-is process map visualizes these:
What are Rework loops, Bottlenecks, Duplicate or unnecessary activities?
To achieve permanent results in removing a defect, focus on these.
What are the root cause(s) or inputs?
This term describes customers’ needs and is used to ensure process outputs align with what is important to them.
What is Voice of the Customer (VOC)?
This phase includes implementing a process control system and project closure.
What is the Control phase?
The most important step in developing a data collection plan is to begin with these.
What are the questions you wish to answer?
This set of measures ensures process outputs are what are important to the customer.
What is Critical to Quality (CTQ)?
These are barriers to root cause analysis:
What are Team resistance to change, Leap to a solution, Preconceived notions for causes?
These are examples of Voice of the Customer information:
What are Interviews, Complaints, Positive letters from customers?
This phase is the best decision point to determine if a project is worth continuing or should be stopped.
What is the Measure phase?
This tool shows a summary across categories for measures of data center, spread, and shape.
What is a Box Plot?
This Pareto chart defect categories Emulsion (65), Other (30), Sewing (20), Grease (15) from left to right.
What is Emulsion, Sewing, Grease, and Other?
When a manager suspects poor performance at a service center, the best approach is to gather raw data to validate and understand the difference in performance.
What is agree to look into it and gather raw data?
