It should state

What  - is the problem- should be stated in terms of results, not causes.

Where  - the problem occurred

When  - the problem occurred

Who  - is involved 

In short, a good problem statement should explain the

Characteristics of weakness orientation:

• Focus on facts - base actions on facts, not opinion

• Focus on process, not results

• Focus on root causes, not solutions

encourages objective analysis of causes (“What caused the delays?”), not

 jumping first to solutions (“What can we do to improve”) 

(Strength orientation focuses quickly on solutions without dwellingon data and analysis)

• Stratify the data to the extent possible

•  All the data (Quantitative),observations (Qualitative)

should be tabulated

While Srinivasan and Kurien s have new

imported sewing machines. Fatima has an old

local machine which gets stuck frequently.

*What do you think of Fatima‟s performance? 

Most of Srinivasan and Kurien‟s work is steady, simple

garment stitching, yet they have considerable number

difficult jobs and her work is practically errorless.*What do you think of Fatima‟s performance? 

Fatima does her stitching easily without much strainwhereas Srinivasan and Kurien struggle to stitch the

•Use checksheets for collecting data

•Design your own check sheet to collect data

•Do not believe in the past data;always suspect it

•If you design the experiments for collecting data,

collect and record as much data as possible –

experiments are costlier.

Example: Record the roundness errors and cylindricity

errors and the direction of the high points (orientation) etc.,

while collecting data on diameter

Stratification of data

•  Design the data collection sheet which will help stratification of

data

Major categories for stratification

1) Within unit variation

2) Unit to unit variation

3) Time to time variation

Variation is the subset of variability. Variation is present due to

common causes whereas variability is present due toassignable causes as well as common causes.

• Identify whether the problem is chronic or sporadic.

• Select appropriate tool depending on problems

• For chronic problems, cause verification to bevalidated statistically.

• Never assume things.

• Select appropriate countermeasures from alternate

countermeasures.• Countermeasures should be for root causes and not

for phenomena / problem

• Check for side effects.

„The quality level in any case should not deterioratefrom the existing level‟

The scrap to be brought down to zero.

The tearing was due to burr carried by coolant to the cutting

edge.

The burr was not filtered due to conveyer not working.

The conveyer was not working since component got jammed in

between conveyer and coolant tank.

Component falling into the tank was avoided by providing a filter

on the coolant flow path by VBS, during wk.10

How to Check

• Compare the results before and after implementation

of countermeasure.

• Use the same charts, measures used in

define/ observation phase.

• Monitor the results at least for 3 months.

• Monitor that the actions are in place.

QC Story Methodology - Summary

8/10/2019 QC Story.ppt

http://slidepdf.com/reader/full/qc-storyppt 131/146

QC Story-Executives Page 141

QC Story 

is a systematic method to solve

problems.

Steps involved

Meas re & Impro e

8/10/2019 QC Story.ppt

http://slidepdf.com/reader/full/qc-storyppt 132/146

QC Story-Executives Page 142

Measure & Improve

1. Define  problem 

. 2. Observation for clues, nature of occurrence. 

3. Analysis for root cause / causes.

4. Action  implement countermeasures.

5. Check  for results.

6. Standardisation  of  the learning.

7. Horizontal deployment  of benefits.

Golden Rules in Problem Solving

1 Go with an open mind

8/10/2019 QC Story.ppt

http://slidepdf.com/reader/full/qc-storyppt 133/146

QC Story-Executives Page 143

1. Go with an open mind.

2. Observe the Genba where it occurred for clues.3. There is no “Bhramhastra” for solving all our problems. 

4. Select the appropriate tool and apply them effectively.

5. Involve more than one person and especially people atthe Genba.(Ten persons idea is better than one

person‟s knowledge) 

6. Validate the countermeasures for effectiveness and

side effects.

7. Standardise the learning.

8. Never give up.

Guidelines for Use of QC Story

„For small problems without much of data analysis,use kaizen sheets.‟ 

„For other problems, use QC Story

with data analysis.‟
