USING PREDETERMINED TIME (MTM ANALYSIS) TO DETERMINE STANDARD TIME. General Hospital wants to set the standard time for lab technicians to pour a tube specimen using MTM.^4
APPROACH \blacktriangleright This is a repetitive task for which the MTM data in Table 10.3 may be used to develop standard times. The sample tube is in a rack and the centrifuge tubes in a nearby box. A technician removes the sample tube from the rack, uncaps it, gets the centrifuge tube, pours, and places both tubes in the rack.

| ELEMENT DESCRIPTION | ELEMENT | TIME |
| Get tube from rack | AA2 | 35 |
| Uncap, place on counter | AA2 | 35 |
| Get centrifuge tube, place at sample tube | AD2 | 45 |
| Pour (3 sec) | PT | 83 |
| Place tubes in rack (simo) | PC2 | 40 |
