problem solving
what is a problem?
• A GAP between the current state and
the desired state.
• All problems are opportunities for
continuous improvement
problem solving?
• Solving problems by finding real root causes
• Taking action that permanently removes the
problem
• Involves two main strategies
• Data Collection/Analysis
• Correction/Prevention
when?
• When our customers require it
• When we wish to solve recurring problems in a
manner that is permanent
• As a continuous improvement tool
• To satisfy a documentation requirement
why this approach?
• A structured approach
that helps build a
common problem
solving language

WIIFM
• Communications
describe the problem
• The goal is to:
• Specify the internal/external customer problem by
identifying in quantifiable terms (who, what, when,
where, why, how, how many) for the problem.
• Use an “Operational Definition” that has a common meaning to
everyone who reads it
• Use verifiable criteria
• Symptoms are often mistakenly used to describe a problem

• Poor: Our customers aren’t happy with us lately.
• Better: The customer retention rate has declined
from 92% to 89% in the last 12 months and is not
meeting our goal is 91% or better.
• Poor: We need a new phone system.
• Better: Our current phone system has capacity for
only 50 extensions and we currently have 65
employees who require a phone.
process flowchart
• A flow chart/value stream map (VSM) is a tool that
helps to identify the actual flow of sequence of
events in a process that a product or service
follows.

containment
• The goal is to:
• Define and implement containment actions to isolate
the effect of problem from any internal/external
customer until corrective action is implemented
• Verify the effectiveness of the containment action
containment
• Minimize the effect of the problem on the customer by
implementing immediate containment actions
• 100% sorting/inspection
• Quarantine
• Temporary SOP’s
• Do/Perform/Make in-house vs outsource
• Temporary company policies
• Additional approvals (signoff)
• Single source
• Certified people
• Additional resources
common problems
• Considered as permanent solution
• Easily forgotten
• Costly
• Typically only address an effect and not
root cause
• Same problem/effect will surface again
define root causes
• If you don’t address the root cause… the
problem will come back.
root cause analysis?
• Process to arrive at the preliminary causes of a
problem
• Finding the reason a problem exists and eliminate
it with corrective actions
• Front-end work
• Defining the problem in quantifiable terms
• Testing potential root causes
• Verifying the root cause
common barriers?
• Problem described incorrectly
• Problem solving effort expedited
• Poor team participation
• No logical process
• Permanent corrective action not implemented
• Over-reliance on experience
define root causes
• The goal is to:
• Identify all potential causes that could explain why the
problem occurred
• Isolate and verify the root cause by testing each
potential cause against the problem description
identify potential
causes
• Identify all potential causes
that could explain why the
problem occurred
• Develop a complete picture of
all of the possible causes of the
problem

• Continue to ask the repeated “Why” statements

Guidelines for
Brainstorming
• Don’t critique ideas.
• Use your imagination!
• Build on others’ ideas.
• Piggybacking
• Aim for QUANTITY.
• Record each idea.
Brainstorming
Process
• Select a facilitator.
• Give everyone 1-2 minutes to silently think about
the problem.
• Invite everyone to contribute ideas.
• Write down all ideas.
• Continue until you run out of ideas.
• Discuss and narrow down ideas using Nominal
Group Technique or Multi-Voting.
cause & effect
diagram
• A Cause & Effect Diagram is a tool that helps to
identify, explore, and display in increasing detail all of
the possible causes related to a problem or condition
in order to discover its root cause(s).

No-one returning phone calls promptly
Lack of cross-selling, lack of touch-points with clients

develop permanent
corrective actions
• Define the best permanent corrective
actions
• Choose on-going controls and measures
to ensure the root cause is eliminated
identify solutions
• Investigate several methods to fix the
problem
• Brainstorm solutions
• Identify similar problems previously solved and
corrective actions
• Review FMEAs
• Consider new technology for the possible solution

Nominal Group Technique is useful
when individual ideas and
judgments need to be tapped and
a group consensus is the desired
outcome.
Consensus is reached when all
members who contribute to a
decision feel their contributions
are given a fair hearing, and are
satisfied with the decision.
getting to consensus
• Consensus means that all members of the team agree
upon a single alternative which is:
• reached fairly and openly, and
• is the best alternative at the time it is made.
• Ask, “Is there anyone here who cannot live with this
decision?”
guidelines
• Review and clarify the list of ideas.
- Eliminate overlap.
- Include all ideas.
• Rate ideas using three prioritized votes per person.
• Most important = 3
• Second most important = 2
• Third most important = 1
• Total the scores for each idea.
• Rank the ideas and attempt to reach consensus
from among the 2 or 3 highest ranked ideas.

• Put the action plan into place
• Verify corrective actions before the actions are
permanently implemented
