 PLAN

• Recognize a problem exists

• Form a quality improvement team

• Develop performance measures

• Clearly define the problem

• Document and analyze problem/process

• Determine possible causes

1. Spray nozzles which frequently clog with particles

2. Our Group

3. If nozzles are not clogging anymore, our performance is effective.

4. Occurring bottleneck for whole manufacturing plant

5. It appears that small particles become clogged in the tiny orificies of the nozzles

6. Nozzles have collected particles. It is found to be coated with a layer of hard soap at the bottom of tank. Besides, nozzles are too small

 PROBLEM STATEMENT:

Because of lack of enough space in nozzles the spray nozzles on the Automatic Parts are constantly clogged

 INFORMATION GATHERED

Nozzles don’t spray as freely as they should

On 7 occasions the nozzles clogged entirely.

Two of them occurred in midday

Remainder happened at the end of day.

Why clogging?

There is small particles which clogs orifices of nozzles

Restricts flow of soap & water solution

Finally shutting everything down

 REVISED PROBLEM STATEMENT

In addition to small space of nozzles the soap-water solution clog the nozzles even more and causes the shut Automatic Parts Washer to shut down.
