8D

Problem Solving Process

8D is a problem-solving

methodology for

product and process

improvement.


3/28

8D Problem Solving Process

It is structured into eight

disciplines, emphasizing team

synergy.

The team as whole is better and

smarter than the quality sum of

the individuals.


4/28


Each discipline is supported by

a checklist of assessment

questions, such as

"what is wrong with what",

"what, when, where, how

much".


5/28


1. Use Team Approach

2. Describe the Problem

3. Implement and Verify Interim

Actions (Containment)

4. Identify Potential Causes


6/28


5. Choose/Verify Corrective Actions

6. Implement Permanent Corrective

Actions

7. Prevent Recurrence

8. Congratulate Your Team


7/28

1. Use Team Approach

Establish a small group of

people with the knowledge,

time, authority and skill to

solve the problem and

implement corrective actions.

The group must select a team

leader.


8/28

1. Use Team Approach Ensure these people have the

time and inclination to work

towards the common goal.

Get your people on board by

using team building tools such asice-breakers and team activities.


9/28

2. Describe the Problem How can you fix it if you

dont know whats

broken?

The more clearly you

describe the problem, themore likely you are to

resolve it.


10/28

2. Describe the Problem Describe the problem in

measurable terms.

Specify the internal or

external customer

problem by describing itin specific terms.


11/28

2. Describe the Problem Be specific and

quantify the problem

where possible.

Clarify what, when,

where and how much


12/28

3. Implement and Verify

Interim Actions (Containment)

What sticking plaster can you use until youfigure out whats really causing the problem?


13/28



Define and implement those

intermediate actions that will

protect the customer from the

problem until permanent

corrective action is implemented.

Verify with data the effectiveness

of these actions.


14/28



After Implementing a temporary

fix, monitor and measure the

impact to ensure its not making

things worse.

Remember to keep going, as asticking plaster will never cure a

broken leg!


15/28


There will be many suspects causing the

problem, but usually only one culprit.

The key is figuring out which one.


16/28


Identify all potential causes which

could explain why the problem

occurred.

Test each potential cause against

the problem description and data.

Identify alternative corrective

actions to eliminate root cause.


17/28


This is where it can get a bit numerically challenging, as

statistical tools are often used to get a deep

understanding of what is going on in a process.


18/28

5. Choose/Verify Corrective

Actions

You know whats causing the problem how are you going to fix it?


19/28


Actions

Test to make sure that your

planned fixes have no

undesirable side effects.

If so, are there

complementary fixes that

eliminate side effects?


20/28


Actions If your solution just isnt

feasible, you can still change

your mind before you move to

the next go live stage.

Define other actions, ifnecessary, based on potential

severity of problem.


21/28

6. Implement Permanent

Corrective Actions

Go for it! Implement

your permanent and

complementary fixes and

monitor to make sure itsworking.


22/28


Corrective Actions

Choose on-going

controls to insure the

root cause is

eliminated.

Control


23/28


Corrective Actions

Usually you will get it

right, but if not, go back a

few steps and try again

the culprit is there to becaught!


24/28


If youve gone to all this trouble, you dont what the

problem to sneak up on you again!


25/28


Prevent recurrence of the problem byupdating everything related to the

process e.g.

Modify specifications,

update training,

review work flow,

improve practices and procedures

to prevent recurrence of this and all

similar problems.


26/28


Teamwork got you this

far, so put on your

collective party shoes

and celebrate your

success.


27/28


Going public with success

spreads knowledge and

learning across your

organization, and lets face

it, we all like a little

recognition now and again.


28/28


Recognize the collective efforts of your team.

Publicize your achievement. Share your

knowledge and learning.
