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 |
