1. MOST – Maynard Operation Sequence Technique
In MTM:
the elements are stand alone and do not relate to the sequence of the operation
In MOST:
The compete sequence of the operation, which consists of smaller elements, is addressed

2. What is MOST ? Maynard Operation Sequence Technique
Developed by Zandin (1980)
Utilizes larger blocks of fundamental motions than MTM-1
General Move
A B G A B P A
Controlled Move
A B G M X I A
Tool Use
A B G A B P _ A B P A

3. Three activity sequences in MOST
The General Move Sequence (for a free movement through air)
The Controlled Move Sequence (for a movement in which the object remains in contact with a surface or is attached to another object during the movement)
The Tool Use Sequence (for the use of common hand tools)

4. Why MOST?
It is much faster than traditional time study technique (e.g. Basic MOST is 40 times faster than MTM-1)
Accuracy of up to 95% can be obtained
It requires less documentation

5. Remember TMU ?
Time for therbligs is measured in Time Measurement Unit (TMU)
1 TMU = hour
= minute
= second
1 hour = 100,000 TMU
1 minute = 1,667 TMU
1 second = 27.8 TMU

9. Example Reach 24”, grasp, move 24” in front.
Get cover, and place in front.
Reach 24”, grasp, move 24” in front.
Open cover.
Reach the cover with other hand by 30”, grasp the flap of cover, disengage the flap with normal effort, turn flap by 120 degree.
Remove spec from the cover, and place aside on table.
Grasp the spec inside the cover, move it out of the frame by 4”, move it on the table by 30”
Close the cover.
Reach for the cover flap in other hand, turn the cover to close, apply slight pressure
Put the cover aside.
Move it back to previous position in 30”
