Problem Solving
"If the only tool you have is a hammer, you
tend to see every problem as a nail"
Abraham Maslow (1908-1970)
The DMAIC Team Based Problem Solving Process
uses a suite of tools, applied within a structured
framework to support the problem solving process
using teams.

Slide 3
The Quality Problem Solving Tools

Ishikawa's 7 Tools of
Quality
 Flowcharts
 Fishbone diagrams
 Pareto charts
 Histograms
 Run charts and
graphs
 Control charts
 Scatter diagrams

Other commonly used
tools:
 Brainstorming
 Multi-voting
 Check sheets
 Dot plots
 Box plots

Slide 4
Types of Problem Solving


Issues driven problem solving, where the focus is
on solving a specific, clearly identifiable and
obvious problem (or symptom). This is usually the
case during the first few years of implementing a
team based problem solving process where many
long standing problems have been flushed out into
the open;
Process Improvement driven problem solving,
where the process improvement process provides
the impetus to analyse the way things are done and
seek out problems to be solved.

The Six Sigma Approach
DMAIC
Control by standardising
solution and monitoring
performance.
Improve by
implementing potential
solutions.
Define the problem or
opportunity.

Develop a Problem/Opportunity Theme
Statement


The problem/opportunity theme statement provides
the initial definition of the problem/opportunity area
to be pursued;
It is on the basis of the problem/opportunity theme
statement that management decide to allocate
resources (the problem solving team) and time to
develop a project team charter and determine
whether the problem/opportunity is worth pursuing.
© Max Zornada (2005)
Slide 10
Problem/Opportunity Theme Statement
Project Title:
Cost of Waste Reduction Project
What is the area of concern? What first brought this problem or opportunity to
the attention of your business?
The cost of waste in the box packaging operations. Now that we are packaging to fulfil 3rd
party contracts, we are having to absorb the cost of waste in order to be cost competitive
on price.
What impact has this problem already had? What evidence is there that it is a
problem worthy of attention?
The impact of this problem is that 3rd party box packaging operations runs at a loss.
Actual costs/box are 44c above recovery rate. This is $1.44 above target.
What will happen if the business does not address this problem?
The remainder of the business will have to continue to cross-subsidise the loss making box
packaging operation or box packaging will have to be shutdown.
Summary problem statement (summarise the above in a concise statement).
The cost of waste in box packaging is excessive and causes box packaging operations to run
at a loss. The cost of waste needs to be reduced to achieve target cost levels.

The Define Stage


During the Define Stage, we:
 Define our problem or opportunity and improvement
objectives;
 Define the customers and their requirements - the
Critical-to-Quality issues (CTQ);
 Define the process that will be affected;
 Develop a plan for completing the project;
Key outputs of the Define Stage:
 Team Project Charter and Work Plan
 Measurable Customer Requirements - Customer
Requirements Statement
 Process Map/Process Analysis.

Problem/Opportunity
Definition
What is the Problem to be solved or the
opportunity this project will exploit.
The cost of waste in box packaging is excessive and causes box
packaging operations to run at a loss. The cost of waste needs to
be reduced to achieve target cost levels.
Objective
Improvement target, impact on Sigma,
COQ/COPQ and Customer Satisfaction
Reduce net spoilage rate by 50% from 6% to 3%. Estimated
Sigma level improvement from 3 to 3.4
Business Case
What improvement in business performance
is expected. $ impact and by when.
Reduction in cost of waste of $253,000 p.a. from a baseline of
$506,000. Will result in target processing cost/box being
achieved.
Team Members
Who are the team members and key experts
to be consulted.
Jane Verde (Team Leader), Paul Black, Rachel Cintura, Roland
Thompson, Sdravo Krysevic, Giovanni Nero (Black Belt)
Project Scope
Which part of the process will be investigated
Box packaging from start of box filling through to placement
of product on buyer shelves.
Customer Benefit
Who are the final customers. What benefits
will they see and what are their most critical
requirements.
The packaging contractees for whom we package and deliver
product to buyers such as supermarkets and wholesalers.
Benefits: competitive costs and more accurate schedule
compliance.

What is this customer’s major complaint? What issue would they want us to work on?
*Note: customer has not complained about price because we are absorbing difference between market price and
actual costs. If customer were charged actual cost we would lose the business.
In addition to price, getting the delivery amount right is a Critical-to-Quality issue for the customer.


Review the previous non-pareto causes to see which
ones have upgraded themselves and assess whether
these are worth going after;
Review any obvious opportunities to apply the
solution in other areas;
Communicate the solution to other parts of the
organisation where it may also apply;
Review and document lessons learnt and
institutionalise the learning.

SEPF Epilogue



The benefit generated by this project was $208,000 per
annum. This is $45,000 short of target;
Addressing the next two highest causes could potentially yield
the following benefits:
 Incorrect coding of contents: $39,000 p.a.
 Box not sealed: $34,000 p.a.
 I.e. a total of $73,000 p.a. if both eliminated. This
would exceed the original target.
Note: The second CTQ characteristic of concern to customers
- schedule compliance - amount delivered benefited as a sideeffect. The main contributor to incomplete orders was the
rejected & returned boxes.
