Designing a Test Fixture with DFSS Methodology

Table 2

Current test fixture VSM summary.

Process step	H/T	T/T	Opportunity for improvement?	Description
Move test fixtures	10 min	0 min	Yes	If test fixture can be made easier to handle and not require a forklift, this time can be reduced
Insert test plugs	2 min	0 min	No	Line must be plugged; plug is simple and will be needed regardless of the remaining fixture design
Place test fixtures	18 min	0 min	Yes	If test fixture can be made simpler, this time can be reduced
Fill line	0 min	5 min	No	Line must be filled for test and the test fixture does not affect this step
Perform test	0 min	15 min	No	Pressure test must be run for set amount of time per requirements
Unthread and remove fixtures	29 min	0 min	Yes	If test fixture can be made simpler, this time can be reduced
Remove plugs	1 min	0 min	No	Plug is already simple and time is already very short
