THE TOOLS
CATWOE
Developing a Robust Problem Definition
CATWOE stands for:
Customers
Who are they, and how does the issue
affect them?
Actors Who is involved in
the situation? Who will be involved in implementing solutions? And what will
impact their success?
Transformation Process What
processes or systems are affected by the issue?
World View What is the big
picture? And what are the wider impacts of the issue?
Owner Who owns the
process or situation you are investigating? And what role will they play in the
solution?
Environmental Constraints What
are the constraints and limitations that will impact the solution and its
success?
The FOCUS Model
A Simple, Efficient Problem-Solving Approach
Identifying problems is like harvesting fruit.
About
the Model
The FOCUS* Model is a structured approach to Total
Quality Management (TQM), and it is widely used in the health care industry.
The model is helpful because it uses a team-based
approach to problem solving and to business-process improvement, and this
makes it particularly useful for solving cross-departmental process issues. Also, it encourages people to rely on
objective data rather than on personal opinions, and this improves the quality
of the outcome.
It has five steps:
Find the problem.
Organize a team.
Clarify the problem.
Understand the problem.
Select a solution.
Applying the FOCUS Model
Step 1: Find the Problem
· identify a process that needs to be improved
· follow the Pareto Principle, where 80 percent of issues come from 20
percent of problems.
· Start with a simple problem to get the team up to speed with the FOCUS
method.
· If you have several problems that need attention, list them all and use
Pareto Analysis, Decision Matrix Analysis, or Paired Comparison Analysis to
decide which problem to address first.
Step 2: Organize a Team
· assemble a team to address the problem
· bring together team members from a range of disciplines – this will give
you a broad range of skills, perspectives, and experience to draw on
· Select team members who are familiar with the issue or process in hand,
and who have a stake in its resolution
· If your first choice of team member isn't available, try to appoint
someone close to them, or have another team member use tools like Perceptual
Positioning and Rolestorming to see the issue from their point of view.
· a diverse team is more likely to find a creative solution than a group of
people with the same outlook.
Step 3: Clarify the Problem
· define the problem clearly and concisely
· the key to success is to break it down into "sushi-sized"
pieces that can be analyzed and solved more easily
· Use the Drill Down technique to break big problems down into their
component parts. You can also use the 5
Whys Technique, Cause and Effect Analysis, and Root Cause Analysis to get to
the bottom of a problem.
· Record the details in a problem statement, which will then serve as the
focal point for the rest of the exercise (CATWOE can help you do this effectively.)
· The problem statement must be objective.
· be on guard against "factoids" – statements that appear to be
facts, but that are really opinions that have come to be accepted as fact.
Step 4: Understand the Problem
· gather data about the problem to understand it more fully.
· Dedicate plenty of time to this stage, as this is where you will identify
the fundamental steps in the process that, when changed, will bring about the
biggest improvement.
· Consider what you know about the problem. Has anyone else tried to fix a
similar problem before? If so, what happened, and what can you learn from this?
· Use a Flow Chart or Swim Lane Diagram to organize and visualize each
step; this can help you discover the stage at which the problem is happening.
· And try to identify any bottlenecks or failures in the process that could
be causing problems.
· As you develop your understanding, potential solutions to the problem may
become apparent.
· Beware of jumping to "obvious" conclusions – these could
overlook important parts of the problem, and could create a whole new process
that fails to solve the problem.
· Generate as many possible solutions as you can through normal structured
thinking, brainstorming, reverse brainstorming, and Provocation. Don't criticize ideas initially – just come up
with lots of possible ideas to explore.
Step 5: Select a Solution
· select a solution
· Use appropriate decision-making techniques to select the most viable
option. Decision Trees, Paired
Comparison Analysis, and Decision Matrix Analysis are all useful tools for
evaluating your options.
· Once you've selected an idea, use tools such as Risk Analysis, "What
If" Analysis, and the Futures Wheel to think about the possible
consequences of moving ahead, and make a well-considered go/no-go decision to
decide whether or not you should run the project.
Note:
People commonly use the FOCUS Model in conjunction
with the Plan-Do-Check-Act cycle.
Key
Points
1.
The FOCUS Model is a simple quality-improvement tool
commonly used in the health care industry.

Clarify the problem.
Understand the problem.
Select a solution.
3.
People often use the FOCUS Model in conjunction with
the Plan-Do-Check-Act cycle, which allows teams to implement their solution in
a controlled way.
5 Whys
Getting to the Root of a Problem Quickly
How
to use the 5 Whys technique, with James Manktelow & Amy Carlson.
To solve it properly, you need to drill down through
the symptoms to the underlying cause. This article looks at Sakichi Toyoda's 5 Whys
technique – a simple but powerful tool for quickly uncovering the root of a
problem, so that you can deal with it once and for all.
About
the Tool
Sakichi Toyoda, one of the fathers of the Japanese
industrial revolution, developed the 5 Whys technique in the 1930s. He was an industrialist, inventor and founder
of Toyota Industries. His technique
became popular in the 1970s and Toyota still uses it to solve problems today.
Toyota has a "go and see" philosophy. This means that its decision making is based
upon an in-depth understanding of the processes and conditions on the shop
floor, rather than reflecting what someone in a boardroom thinks might be
happening.
The 5 Whys technique is true to this tradition, and
it is most effective when the answers come from people who have hands-on
experience of the process being examined. It is remarkably simple: when a problem
occurs, you uncover its nature and source by asking "why" no fewer
than five times.
When
to Use the 5 Whys
You can use the 5 Whys in troubleshooting, quality
improvement and problem solving, but it is best for simple or moderately
difficult problems.
The simplicity of the 5 Whys tool gives it great
flexibility, too, and it combines well with other methods and techniques. It is often associated with lean manufacturing
(also part of the Toyota Production System), where it is used to identify and
eliminate wasteful practices. It is also
used in the analysis phase of the Six Sigma quality improvement methodology.
How
to Use the 5 Whys
The 5 Whys is a simple, practical tool that is very
easy to use. When a problem arises, simply keep asking the question
"why" until you reach the underlying source of the problem, and until
a robust counter-measure becomes apparent.
Note:
1.
The 5 Whys uses "counter-measures," rather
than solutions. A counter-measure is an
action or set of actions that seeks to prevent the problem arising again, while
a solution just seeks to deal with the situation. As such, counter-measures are
more robust, and are more likely to prevent the problem from recurring.
2.
Each time you ask "why," look for an
answer that is grounded in fact: it must be an account of things that have
actually happened – not events that might have happened.
3.
Keep asking "why" until you feel confident
that you have identified the root cause and can go no further.
Key
Points
1.
The 5 Whys strategy is an easy to use, effective
tool for uncovering the root of a problem. You can use it in troubleshooting,
problem solving and quality improvement initiatives.
2.
Start with a problem and ask "why" it is
occurring. Make sure that your answer is grounded in fact, then ask
"why" again. Continue the process until you reach the root cause of
the problem, and you can identify a counter-measure that prevents it recurring.
3.
Bear in mind that this questioning process is best
suited to simple to moderately-difficult problems. Complex problems may benefit
from a more detailed approach (although using 5 Whys will still give you useful
insights.)
Cause and Effect Analysis
Identifying the Likely Causes of Problems
(Also known as Cause and Effect Diagrams, Fishbone
Diagrams, Ishikawa Diagrams, Herringbone Diagrams, and Fishikawa Diagrams.)
Cause & Effect Diagrams
Find all possible problems.
When you have a serious problem, it's important to
explore all of the things that could cause it, before you start to think about
a solution. That way you can solve the
problem completely, first time round, rather than just addressing part of it
and having the problem run on and on.
Cause and Effect Analysis gives you a useful way of
doing this. This diagram-based
technique, which combines Brainstorming with a type of Mind Map, pushes you to
consider all possible causes of a problem, rather than just the ones that are
most obvious.
About
the Tool
Cause and Effect Analysis was devised by professor
Kaoru Ishikawa, a pioneer of quality management, in the 1960s. The technique was then published in his 1990
book, "Introduction to Quality Control." The diagrams that you create with Cause and
Effect Analysis are known as Ishikawa Diagrams or Fishbone Diagrams (because a
completed diagram can look like the skeleton of a fish). Cause and Effect Analysis was originally
developed as a quality control tool, but you can use the technique just as well
in other ways.
How
to Use the Tool
Step 1: Identify the Problem
· write down the exact problem. Where
appropriate, identify who is involved, what the problem is, and when and where
it occurs.
· write the problem in a box on the left-hand side of a large sheet of
paper, and draw a line across the paper horizontally from the box. This
arrangement, looking like the head and spine of a fish, gives you space to
develop ideas.
Figure 1 – Cause and Effect Analysis Example
Tip 1: Some people prefer to write
the problem on the right-hand side of the piece of paper, and develop ideas in
the space to the left. Use whichever approach you feel most comfortable with.
Tip 2: It's important to define
your problem correctly. CATWOE can help you do this – this asks you to look at
the problem from the perspective of Customers, Actors in the process, the
Transformation process, the overall World view, the process Owner, and
Environmental constraints.
Step 2: Work Out the Major Factors Involved
· identify the factors that may be part of the problem. These may be
systems, equipment, materials, external forces, people involved with the
problem, and so on.
· Try to draw out as many of these as possible. As a starting point, you
can use models such as the McKinsey 7S Framework (which offers you Strategy,
Structure, Systems, Shared values, Skills, Style and Staff as factors that you
can consider) or the 4Ps of Marketing (which offers Product, Place, Price, and
Promotion as possible factors).
· Brainstorm any other factors that may affect the situation.
Step 3: Identify Possible Causes
· brainstorm possible causes of the problem that may be related to the
factor.
· Where a cause is large or complex, then it may be best to break it down
into sub-causes. Show these as lines
coming off each cause line.
Step 4: Analyze Your Diagram
· Depending on the complexity and importance of the problem, you can now
investigate the most likely causes further.
Tip: A useful way to use Cause and
Effect Analysis with a team is to write all of the possible causes of the
problem down on sticky notes. You can then group similar ones together on the
diagram.
This
approach is sometimes called CEDAC (Cause and Effect Diagram with Additional
Cards) and was developed by Dr. Ryuji Fukuda, a Japanese expert on continuous
improvement.
Key
Points
1.
Professor Kaoru Ishikawa created Cause & Effect
Analysis in the 1960s. The technique uses a diagram-based approach for thinking
through all of the possible causes of a problem. This helps you to carry out a
thorough analysis of the situation.
2.
There are four steps to using Cause and Effect
Analysis.
Identify the problem.
Work out the major factors involved.
Identify possible causes.
Analyze your diagram.
Appreciation (Situational)
Understanding the Full Implications of a Fact
Appreciation
Squeeze out as much information as you can, by
appreciating the situation accurately.
Sometimes we're given a piece of information that
seems straightforward, only to find out later that more was going on than we
thought. As a result, we're then
unprepared to deal with the consequences.
One way to deal with these situations is by using
Appreciation. This is a simple but
powerful technique for extracting the maximum amount of information possible
from a simple fact or statement.
About
Appreciation
Appreciation helps us uncover factors that we might
have ordinarily missed, and it can be very useful for brainstorming solutions
to problems.
It was originally developed by the military to help
commanders gain a comprehensive understanding of any fact, problem or situation
that it was faced with in battle.
Using Appreciation starts with a fact, you first ask
the question "So what?" – in other words, what are the implications
of that fact? Why is this fact important?
You then continue asking that question until you
have drawn all possible conclusions from it.
Uses
1.
Appreciation is similar to the 5 Whys technique. The
major difference is that it is often used to get the most information out of a
simple fact or statement, while the 5 Whys is specifically designed to drill
down to the root of a problem.
2.
also use Appreciation in conjunction with Root Cause
Analysis or Cause and Effect Analysis to help you gain a better understanding
of the impact of possible solutions.
Note:
Bear in mind that Appreciation can restrict you to
one line of thinking. Repeat the
Appreciation process several times over to make sure that you've covered all
bases.
Key
Points
1.
Appreciation was originally developed by the
military to give leaders a better understanding of a fact, statement or problem
that they were faced with.
2.
You use Appreciation by asking "So what?"
repeatedly. This helps you to extract all important information implied by a
fact.
3.
Consider using other problem solving techniques with
Appreciation, to make sure that you're not limited to one line of thinking.
