Elemental Standard Time Data
.Elemental standard-time data are obtained from previous time studies and codified in tables in a handbook or in a computer data bank. Such data are used to develop time standards for new jobs or to make time adjustments to reflect changes in existing jobs. They are more correctly viewed as normal-time data, because tabled values have been modified by an average performance rating, and allowances must be added to obtain a standard time. Calculating a time standard for a new job using elemental standard-time data tables entails the following steps:
1. Break down the new job into its basic elements. Match these elements to the time for similar elements in the table.
2. Match these elements to the time for similar elements in the table.
3. Adjust element times for special characteristics of the new job. (In metal cutting, for example. this is often done by a formula that modifies the time required as a function of type of metal, size of the cutting tool, depth of the cut, and so forth.)
4. Add element times together and add delay and fatigue allowances as specified by company policy for the given class of work.
The obvious benefit of elemental standard data is cost savings in that it eliminates the need for a new time study every time there is a new job. This saves staff time and avoids disruption of the workforce. The main practical requirement of the approach is that the elemental data must be kept up to date and easily accessible
