SIX SIGMA PRINCIPLES

DAY 5: MARCH 25, 2020

HOUSEKEEPING

• Engage in today’s learning session by utilizing the voting & chat features in Zoom

• All lines have been muted

• Today’s session is being recorded and will be available for review on the program website

• Bookmark the Resources & Templates web page https://www.neomed.edu/lss/resources-templates/

LEARNING OBJECTIVES• Review critical activities that occur during the Analyze Phase

• Explore four tools to improve understanding of the relationship between KPIV &KPOV

– Value Analysis

– Waste Analysis

• Discuss two Root Cause Analysis tools

DMAIC FRAMEWORK

Control

DMAIC is a systematic process to solve problems & improve business performance

ANALYZE PHASEKey Actions

• Investigate both the process & data to determine what the biggest contributors are to the problem

• Hypothesize about causal relationships between KPIV & KPOV

• Study patterns & data to support observations

• Utilize data to prove what the major contributors are to the undesirable outcome

** Refer to Chapter 14 in the Green Belt self study guide under Supplemental Reading

ANALYZE PHASE TOOLSSubjective Tools – Often Used First• Process Flow Analysis

– Value Analysis– Waste Analysis

• Cause & Effect Analysis – Fishbone Diagram– 5 Whys

Analytic Tools – Used to Verify Subjective Tests• Pareto• Checksheets• Control Charts• Regression Analysis• Hypothesis Testing• Capability Analysis

ANALYTIC TOOLS• Pareto: A pareto chart is a bar chart that displays by frequency, in

descending order, the most important defects.

• Checksheets: Forms, tables, or worksheets facilitating data collection and compilation; allows for collection of stratified data.

• Control Charts: Specialized time plot or run chart showing process performance, mean (average), and control limits

• Regression Analysis: A statistical analysis assessing the association between two variables.

• Hypothesis Testing: The process of using statistical analysis to determine if the observed differences between two or more samples are due to random chance or to true differences in the samples

• Capability Analysis: Determination of whether a process, with normal variation, is capable of meeting customer requirements

VALUE ANALYSISA process that enables you to determine how much of the process is dedicated to activities the customer values

Benefits• Identify & target hidden costs that do not add value to the customer

or product

• Improve product quality by simplifying the process

• Improve Lead Time for the process (Time from customer request to product/service delivery)

VALUE ANALYSISInstructions

1) Select a different color for each of the Value Classifications

2) Review each step in the Process Map & determine which Value Classifications applies

Value Added: Activities defined by the customer as valuable; Customer is willing to pay for it; Transforms an input to output

Business Non-Value Added (Waste): Activities that provide no value to customers, but are necessary given current process limitations – AQ, approvals

Non-Value Added (Waste): Activities that provide no value to internal or external customers

VALUE ANALYSIS

WASTE ANALYSISUtilize process flow tools to identify specific areas of waste in the process

• Delays

• Errors

• Bottlenecks

• Unnecessary Movement / Transportation

• Loop Back / Re-Work Point

• Non-Value Added activities (BNVA & NVA)

ROOT CAUSE ANALYSIS (RCA)Utilize Open-Narrow-Close modelOpen: Gather as many ideas as possibleNarrow: Narrow the list of possibilities to bigger impact ideasClose: Utilize data analysis to validate selected ideas

Level the Playing FieldPerform RCA exercises in a way that is inclusive & neutralizes judgement / bias• Group Activities: Writing ideas on paper instead of vocalization• Individual: Complete exercises independently & submit for

compilation

What else?

CAUSE & EFFECT: FISHBONE DIAGRAMTool that presents all possible causes for a problem grouped by a category

CAUSE & EFFECT: 5 WHYSTool that enables discovery of root cause by asking “WHY” until you’ve reached the point where the true cause is identified.

ACTIVITY1) Think of a problem you are trying

to solve

2) Complete 5 Whys Analysis

3) Share

VALIDATION THROUGH DATA

• Checksheets• Control Charts• Regression Analysis• Hypothesis Testing• Capability Analysis
