Introduction
• It is said the manufacturing industry favours manufactures that are able to apply the
concept of lean manufacturing
− Lean manufacturing entails producing what the customer wants
− In the quantity the customer requires the product in
− And when the customer requires it
− Minimal resources
• Heinz foods is a world renown food manufacture that manufactures frozen and pre-
baked pies
− Strive to be lean in our manufacturing process
− All products that are sent to the customer are packed in an inner & outer carton

Background to problem statement
• The company on an hourly basis can either
be producing goods or not producing
goods
• Illustrated in the graph on the right is data
collected over a period of six months
distinguishing the time between production
and no production.

− no hot filling, power failures and no raw materials
• York
− Situations related to refrigeration such as
refrigeration repair, soft products and product pile
ups inside the York
• Change over
− Chance-over refers to the time lost when switching
from one product to another
• No pastry
− breakdowns occurring on the laminator or
ingredients are not available to produce the pastry
• Cleaning
− production is stopped at the end of the shift prior
completion of the shift
• Klikklok
− breakage on the klikklok and pile-ups that occur on
the klikklok

Background to problem statement
• Klikklok begins to act as a bottleneck
– Team leaders try to apply TOC
– Decreasing capacity, increasing buffer
– More white buckets, more trolleys
– Products can not stay outside refrigeration for
long period of time
– Trolleys are taken to the blast freezer
– Full blast freezer

8
A countermeasure team leaders have taken
in the past
• switch product packaging
– from making 12×6’s to making 1×24’s

Problem statement & project objectives
PROBLEM STATEMENT
The waste produced by the Klikklok machine
is a key contributor to the company not
reaching its desired targets and not being
able to supply the customers with their
desired form of product.
OBJECTIVES
• Raise awareness about the amount of
waste being produced by the Klikklok
• Raise awareness about what transpires
when the klikklok produces waste
• Reduce waste by identifying the root
cause
• Promoting the use of six sigma
methodology for problem solving
• Promoting the use of preventative
maintenance calendar

10
Six Sigma methodology
A feasible way of understanding and dealing
with this problem is to make use of a six
sigma methodology most commonly known
as DMAIC, which is an acronym for Define,
Measure, Analyze, improve and control
ALTENATIVE METHODOLOGY
• Select
• Record
• Examine
• Develop
• Install
• Maintain

11
• Company clients are retails stores
such as Spar and Pick n’ Pay which
distribute Heinz’s products to the
public.
• CTQ characteristic
– Number of units inside
– Condition of the inner packaging box
– Properly sealed box
– Properly dated

• When the machine produces a single
defective box not much information about
the problem can be abstracted from just
that singular box
• However when the machine produces
several defective boxes all sharing similar
characteristics, this provides the perfect
environment for problem solving
The flip on the right hand side, on
the side of the bar code (Bar code is
underneath the box) is not in place.
The box comes out of the klikklok
perfectly sealed but with little or no
units inside.
The flip on the rear end side (right
hand side) of the Litos is glued out of
place also causing a small tear in the
near side of the box.
This Litos is not sealed on either
side and the rear side is wrinkled
and one of the corners is torn.
This Litos jammed whist still inside
the machine hence causing the
machine to stop or risk damaging the
other Litos after it. It is wrinkled on
the side with the bar code and not
sealed on either side

• The cause and effect diagram categorizes variables that may cause variation in the
process leading to an out of control process in four categories namely Man, method,
machine & material.

• Suspicions that the main source of the
problem was due to worn out loader
arms.
• The company purchased the new
equipment
• The repairs were done in week 39
• A great drop in the total waste can be
seen
• Average conformance increased to 98%

• As a means of controlling this process the
P chart can be used again
• This P chart was constructed after the
specialist had come to Heinz to replace
the loader arms on the Klikklok
• The process in technical viewing may still
be seen as being out of control
• however when it is compared to the first
one, a great improvement can be seen.
• 2 points fall outside the desired
specification limits

• Make use of the PM calendar to maintain
the new loader arms
• The main aim of the PM calendar is to
schedule checks that aught to be done
on the machine
• It breaks down the machine in to
individual opponents
• Each component will have a listed set of
tasks that must be done on the e.g.
replace or lubricate
• Each task will also have a frequency
column, which displays how frequent the
task should be done.

Conclusion & Recommendation
Conclusion
• There has been a great improvement in the
waste produced by the Klikklok
• The production figures of have increased
• However there are still points that fall
outside the desired control limits
• This is an indication that the problems
solved up until now are not the only
problems
• And that there is still room for improvement
Recommendation
• Looking at the DMAIC process it is most
beneficial to the organization to go back to
the measure phase
• Study why we have points out of control
after replacing the loader arms
• The use of preventative maintenance in the
form of daily check sheets for individual
parts
• The use of the preventative maintenance
calendar
