PROFILE
Product: Church Bulletins
Accounts: Approximately 800
Volume: Customer order (Varies)
Time: Weekly
Current Issue● Wrong shipment to wrong
account● Less or more quantity than
ordered
PROBLEM
GOAL
To Establish Acceptable Range of Weights for Shipped Packages by
Account
Our Approach
04 Improve
01 Define
02 Measure
03 Analyze
05 Control
Define
Establish a target weight for orders based on:
1. Quantity of bulletins (including overage)
2. Paper type
3. No of pages in a bulletin
4. Weight of the box
Define
SHIPPED WEIGHT▪ Checked at shipping
COMPARE
THEORETICAL WEIGHT RANGE▪ Formula based calculation
Measure
Paper▪ Regular▪ Gloss
Paper Size▪ 11X17 (4 Pg)▪ 11X22 (5 Pg)▪ 11X25.5 (6 Pg)
Printing▪ Inkjet▪ Offset
Box Size▪ AA ▪ B ▪ C ▪ D
Measure
Available Data
▪ Order Quantity ▪ Quantity Printed ▪ Quantity Shipped
▪ Paper Type ▪ Paper Size ▪ Printing Type
▪ No of Boxes Shipped
▪ Shipped Weight ▪ Number of Pages Per Bulletin
Weight of one sheet of paper for Gloss and Regular and for all three
paper sizes
DATA CALCULATED
Measure
Weight of 4 types of Boxes
Analyze
Analyze
Analyze
Analyze
▪ Calculated weight = (Number of pages in one order) X (Weight of one page)
▪ Lower limit = (Calculated weight) + (Number of boxes) X (Weight of AA box)
▪ Upper limit = (Calculated weight) + (Number of boxes) X (Weight of D box)
*Round Down Lower limit and Round up upper limit
Analyze
Theoretical weight range Shipped weights
Compare
48 - 51 45, 50, 50, 50, 51, 52, 60
53% of all data fits within theoretical ranges
Improve
Using▪ No of Bulletins▪ No of Sheets▪ Weight of each
sheet▪ Box weights
Using▪ Calculated
weight▪ SPC Charts
Using▪ Calculated
range ▪ Shipped weight▪ Minitab & Excel
CALCULATE WEIGHT ADD RANGE COMPARE
Target Weight = (Weight per sheet*No. Of sheets) + Weight of the boxes
● Number of sheets = (No. of printed sides per bulletin) X (Total bulletin quantity)
Improve CALCULATE WEIGHT
No. of sides
11X17 4
11X22 5
11X25.5 6
Weight per sheet
Regular Gloss
0.0051795 lb 0.006944 lb.
Box Weight
AA 0.40 lb.
B 0.50 lb.
C 1.05 lb.
D 1.40 lb.

Control Charts in Minitab
▪ Mean
▪ UCL
▪ LCL
▪ Control charts
▪ Outliers
SPC method in Excel
▪ Mean
▪ UCL
▪ LCL
▪ Control charts
▪ Equations for 95% accuracy
CONTROL CHART - Minitab
CONTROL CHART - Excel
Formula SPC - Excel
SPC Range Given Data
44.5 - 58 45, 50, 50, 50, 51, 52, 60
*Equation calculates for 95%
accuracy
● Set mean and control limits for multiple ranges of
bulletin quantities
● Define how control limits change based on paper type,
number of boxes
● Enable LPi to check box weights against given upper and
lower control limits to ensure 95% accuracy or more
Control
▪ Inkjet printed exact number; offset was manually controlled by operator
▪ Data outliers▫ Reshipments▫ Shipments to two or more locations
