CONCEPT OF WORK CONTENT, , , , © Itis defined as thi mount of work which has to be done ina given time to complete the job, , ® generally it ts measured in terms of man hours and machine hours., + Work content has two components. They are,, a. Basic work content, , b. Excess work content, , Basic Work Content, , ® This is the minimum time required theoretically to do the job., , This can not be reduced, , @ The basic work content is the work contained ina job in the following bdeal conditions., a. The design of product ts perfect., , b. Planned manufacturing process is followed without any deviation., , © There is no loss of working time., , d. But the above idle condition is not possible in nature.
