    1. 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. 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. 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. 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. 5 Remember TMU ? Time for therbligs is measured in Time Measurement Unit (TMU) 1 TMU = 0.00001 hour = 0.0006 minute = 0.036 second 1 hour = 100,000 TMU 1 minute = 1,667 TMU 1 second = 27.8 TMU

    9. 9 Example 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

    10. 10 Example Get cover, and place in front. Reach 24, grasp, move 24 in front. A1 B0 G1 A1 B0 P1 A0 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. A1 B0 G3 M1 X0 I0 A0 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 A1 B0 G3 A1 B0 P1 A0

    11. 11 Example Close the cover. Reach for the cover flap in other hand, turn the cover to close, apply slight pressure A1 B0 G1 M3 X0 I0 A0 Put the cover aside. Move it back to previous position in 30 A0 B0 G0 A1 B0 P1 A1
