PMT-X is a powerful measurement system designed to provide a simple, effective means of establishing times for low repetition tasks. The data was designed for the evaluation of work where the more detailed MTM-1 and MTM-2 systems are not economic.  
     
  PMT-X is an independent simplified system. Analysts need not be qualified in other PMT System in order to use it in appropriate areas.  
     
  It is a third generation system based exclusively on MTM and consists of simplified motions and combinations of MTM motions. It is not possible to replace any action in PMT-X by other PMT-X actions.  
     
  The data is suited to evaluating the method actually performed by the operator and is independent of type of work, workplace layout and equipment.  
     
  PMT-X is complementary to all other charting and analytical techniques; it does not replace them. It should be used after broader techniques have established the general Necessity and Purpose, Place, Sequence, Person and Means of the tasks to be evaluated.  
     
 
     
  The former UK MTM Association developed PMT-X as MTM-X, by statistical simplification of the more detailed MTM-1 data, after extensive studies of a large range of work. It is the least detailed level of the multi-level PMT (MTM) Core Data System.  
     
  MTM-X accorded to the criteria established for Combined MTM Data Systems by the International MTM Directorate in 1964:  
     
 
  • Consistency

-between Analysts
-between Areas of Application

  • Fast to handle
  • Universally named
  • Easy to understand
  • Descriptive of the method
  • Combinable with other MTM data
  • Based on MTM data
  • Specified in relation to

 

 

 

 

-Speed of Application
-Accuracy of Results

 
     
 
     
  As a system, PMT-X is ideally suited to work measurement of low repetition work. It has the following advantages over Time Study.  
     
 
  • It is faster to use than Time Study for comparable accuracy and methods description.
  • The need to time and rate operator performance is eliminated.
  • It shows a clear and specific relationship between the method used and the time required for a task.
  • Improved methods and Time Standards can be developed by simulation before a new method is introduced.
  • Machine and equipment alternatives can be compared by simulation before commitment of capital expenditure.
  • Optimum manual methods can be compared with automated or computerised alternative methods to quantify the true scope for savings.
  
 
   
     
  There are 9 actions and motions in the PMT-X system. Only GET and PUT are subdivided by their time-determining variables of distance and complexity. All other actions are represented by single average times. Coding is mnemonic and simple.

  PMT-1 contains 19 motion-time standards. The motions are mutually exclusive and no motion can be sub-analysed in terms of others on the data card. No allowances are included in the data for compensatory rest or other purposes.
