1. To give students an understanding of Quality principles.
2. To give students an opportunity to apply Quality principles.
3. To give Students a better understanding of the nature of work and how business operates.
Using APS fundamentals recommend a visual management system for Potroom Crucible repairs
Crucible repairs is from the time the Crucible leaves the Potroom for Maintenance until the Potroom pick up the Crucible for use in Production

PotroomsPotrooms•Must have 11 crucibles
•Must have 9 lids
•Life of Crucible is unpredictable
•No communication with all groups that are involved with repairs
•Don’t know when a crucible is completed
•Have to wait for the crucible
S & BS & B
•Don’t know when a
crucible is coming
Don’t know the priority
Crucible must be cold
•Can only work on one at a
time
Must wait for room in the
shed
Heavy engineeringHeavy engineering•Have other work
•Don’t want management
interfering
•Can only do one at a time
•Need to hire contractors
when there is extra work
•Complete rebuild takes
around 3 weeks
•Average repairs take 7
weeks
BricklayersBricklayers
•Can only brick one at a time
•Can only cure one at a time
•No warning when a crucible is arriving
•Refractory work is 2 days
•Curing is normally 4 days
Use a Visual Management SystemMANUALlocated in Bld 107 (and possibly in each other work area)
Develop a “pull” system for maintenance of crucibles
Implement counter measures for incidents where more than one crucible enters the maintenance system at one time, or when processes such as HE workshop take longer than the average time eg.3 weeks
ELECTRONICe-mail on computer network

Heavy Engineering,RefractoryS&B Sandblasting
*E-mail from Bld 107 to•Bill Van Berkel•S and B•Heavy Engineering
*Bill Van Berkel raises a work ticket to S&B and Heavy Engineering
*Danny Hooper raises a work ticket for refractory
*Bld 107 do not know if a crucible is completed
*Danny Hooper does not know when a crucible is arriving(cannot plan his workers and shifts)
*E-mail from Bld 107 sent when crucible is out of service to “start the clock” to:
Bill Van BerkelS &BHeavy Engineering includingWayne Durbidge
•Danny Hooper
*Heavy Engineering to notify S&B of estimated completed date
*Establish a central board in Bld 107 that show the status of each crucible in the various repair stages (supported electronically)
Possibility to reduce the number of crucibles in maintenance system
Designated pick-up and drop-off crucibles locations
Suitable machinery to demolish crucibles
Potential for Heavy Engineering Workshop to pick up crucible from S & B
Alter red cure tags to green - in line with basic principals of APS
Extend e-mail systems to include all relevant parties
Determine whether there is a requirement for second hot top
