2. MTM : a generic term for a family of PMTS
PMTS : Pre-determined Motion Time System
method analysis technique where the times established for basic
human motions (classified according to the nature of motion and the
condition under which is made) are used to build up the time for a job
at a defined level of performance;
Basic human motions classification:
a. Object related
b. Behaviour related
MTM – 2 : uses only the Behaviour concepts
classify the motions according to what they look like to an observer
Example for GET motion : movement of the empty hand for a distance of between
5 – 15 cm followed by a grasping action made by a single closing of the fingers

13. 1. Select the operation and a standard, cooperative worker
2. Select the video camera position to record with accuracy the cycle, the full workplace and surroundings
• Cycle: set of work contents that can be completely repeated
3. Make video recordings of few cycles
4. Divide the operation into MTM-2 elements
• Operation : the smallest work contents that can be done by a worker
• Element : part of operation
• Motion : part of element

5. Analysis of the operation with MTM-2 based timeSSD® elements and calculation of cycle time (basic time)
• Noncyclic and / or long-time cycle work contents are not included and analyzed (these are classified as
allowance)
• Considerations during analysis:
▪ Normal and maximum working area (right hand, left hand; male and female)
▪ Operations which contain both manual and machine processes (separately as a series, partial
overlapping, sweeping overlapping)
▪ Mechanized process time (e.g. finishing) approach:
o Machine data handbook or
o Develop theories with specially designed experimentation or
o Direct time study
6. Standard time = Basic time + Allowances
• Allowances (roughly): Personal (5%); Fatigue (about 5%); Delay (about 5%)
