CASE STUDY OVERVIEW

WP Inc. manufactures small metal partsUses customer’s designRecurring problem w/ spray nozzles in parts washer that frequently clogCauses parts washer to shut downCauses serious time delays for everythingParts washer is the only option

PARTS WASHER OVERVIEW

Summers, 2010, p. 48, Fig 3.1

Slide5

PROBLEM-SOLVING STEPS

Plan:Recognize a problem existsForm a quality improvement teamDevelop performance measuresClearly define the problemDocument and analyze problem/processDetermine possible causesDo:Identify, select, and implement the solutionStudy & Act:Evaluate the solutionEnsure performanceContinuous improvement

Summers, 2010, p. 49, Fig 3.2

Slide6

BRAINSTORMING

Plan:Recognize a problem exists – spray nozzles clog frequentlyForm a quality improvement team - meDevelop performance measures – how do I know I have made the correct change? The nozzles aren’t clogging anymoreClearly define the problem – spray nozzles clog frequently, causing serious time delays for the entire manufacturing plantDocument and analyze problem/process – create a logDetermine possible causes – nozzles are too small, nozzles are developing soap scum build up-causing it to clog, pump isn’t strong enough

Summers, 2010, p. 49, Fig 3.2

Slide7

PROBLEM STATEMENT RESULTS

The spray nozzles on the Automatic Parts Washer are frequently clogged because the nozzles are too small.

Slide8

INFORMATION GATHERED

Nozzles don’t spray as freely as they should7 times – nozzles clogged completely2 of these times – clogged midday5 of these times – clogged at end of day0 of these times – morningWhy clogging? Small particles clogging orifices of nozzlesRestricts flow of soap & water solutionCausing nozzles to clog even furtherEventually shutting everything downSmall particles are white/flakelike when dry

Summers, 2010, p. 101

BRAINSTORMING REVISITED

Plan:Recognize a problem exists – spray nozzles clog frequentlyForm a quality improvement team - meDevelop performance measures – how do I know I have made the correct change? The nozzles aren’t clogging anymoreClearly define the problem – spray nozzles clog frequently, causing serious time delays for the entire manufacturing plantDocument and analyze problem/process – create a logDetermine possible causes – nozzles are too small causing the small particles to get stuck, causing the soap/water solution to clog it even more, causing the parts washer to shut down

Summers, 2010, p. 49, Fig 3.2

Slide10

REVISED PROBLEM STATEMENT

The spray nozzles on the Automatic Parts Washer are frequently clogged because the small particles to get lodged in the small orifices, which causes the soap/water solution to clog it even more, eventually causing the Automatic Parts Washer to shut down.

Slide12

NOZZLES WON’T CLOG

NO FILTERING SYSTEM

EVAPORATION

HIGH TEMPERATURE NEEDED

CAUSES OF SOAP BUILDUP IN BOTTOM OF TANK

TEMPERATURES IN TANK TOO LOW

HOW SOAP DISSOLVES BEST

UNNECESSARY INCREASE OF SOAP SOLUTION

DISTURBED SOAP PARTICLES

INCREASES SOAP CONCENTRATION

FILTER NEEDED BEFORE NOZZLES

Plan of action

Restraining forces

Reduce shut downsIncrease manufacturing numbersIncrease productionPrevent Future clogs

Must design filtersMust determine where filter will goMust ensure water temp is warm enough

FORCE-FIELD ANALYSIS

Driving forces

Review and plan to install filter in tankDesign and build filterInstall filterIncrease water temperatureTest

Summers, 2010, p. 79

Slide14

MANAGEMENT SUMMARY

Do:Identify, select, and implement the solutionInstall filters for nozzles in the tankIncrease water temperature in the tank to dissolve soap Study & Act:Evaluate the solutionBecause the temperature is warmer the soap dissolvesIn case the water temperature gets too cool, filters are a back up in prevent clogging nozzles Ensure performanceRun with warmer water and filter installed Corrects the problemContinuous improvementMaintain and clean filters daily at the end of the day to ensure the filters don’t become a clogging problemRegularly test the water temperature to ensure soap is dissolving
