 STANDARD MINUTE VALUE (SMV)

SMV means the time that it takes a worker to complete a specific operation or produce a specific garments.

It is a numerical value which is represented the standard time of a process or operation in a standard environment for standard worker.

    A Standard Time

       The work content of a job includes an allowance for adequate rest for that job.

‘Standard time’ is the average for one cycle of an operation that we would measure over a typical day if we had:

• ·         A skilled operative
• ·         Adequate incentives to call form the operatives’ best efforts.
• ·         Plenty of work so that the operator is not necessary to wait for work.
• ·         The workplace and the machinery for which the standard time was specified
• ·         Output at the correct level of quality
• ·         Time allowed for the operative’s personal needs and to overcome fatigue
• ·         Expected delays, due to minor machine maintenance, thread changes etc:

When we measure this standard time in minutes, we call it as Standard Minute Value.

Standard Minute Value (SMV) = Basic Time + Allowances

                                    Observed Time ×Observed rating

    Basic Time =                           

                                              Standard Rating

In the British standard the standard rating is 100% 
 

Calculate the basic times 

Observed time in minutes	0.25	0.31	0.09	0.22
Observed Rating  %	80	90	110	105

Answers: The basic time should be 0.20, 0.28, 0.10, and 0.23 minutes. 

Steps of calculate SMV:

                               Let, Basic time=A & Allowances=10%

                               SMV=A+10% of A

                                        =A (1+0.10)

                                        =A*1.10

Ø Rating

When an operator performs any activity, the time taken depends not only on the activity itself but also on the speed and effectiveness of the operator. This effectiveness is assessed in relation or comparison to the effectiveness of a standard operator. This assessment is termed as rating.

The concept of rating is merely an extension of assessing performance as fast or slow: It involves the comparison between an actual pace of working and the conception of standard pace in the mind of the observer. Rating is not a measurement but an assessment. Therefore it is always a subjective observation of the operator by the observer, converted to the objective calculation of the operation. With lot of training and experience this mental comparison can give a reliable indication of performance.

Performing a Time Study

Ø  Standard Operator

A standard operator is one who is accepted as having the necessary physical attributes, who possesses the possesses the required intelligence and education and has acquired the necessary skill and knowledge to carry out the work in hand to satisfactory standards of safety, quantity and quality. We have to compare out operatives with the standard operatives and rate them accordingly.

Ø  Standard performance

Standard performance is the rate of output, which qualified workers, will naturally achieve without-exertion as an average over the working day or short, provided they adhere to the specified method and provided they are motivated to apply themselves to their work.

Ø  Basic time

 Time recorded by observing an operator while he/she us doing a task.
