Methods-Time Measurement (MTM) is a predetermined motion time system that is used primarily in industrial settings to analyze the methods used to perform any manual operation or task and, as a product of that analysis, to set the standard time in which a worker should complete that task.
In economics and industrial design, planned obsolescence (also called built-in obsolescence or premature obsolescence) is the concept of policies planning or designing a product with an artificially limited useful life or a purposely frail design, so that it becomes obsolete after a certain predetermined period of time upon which it ...
Most predetermined motion time systems (MTM and MOST) use time measurement units (TMU) instead of seconds for measuring time. One TMU is defined to be 0.00001 hours, or 0.036 seconds according to MTM100 and 0.0000083 hours, or 0.030 seconds according to BS100. [1] These smaller units allow for more accurate calculations without the use of decimals.
In business and for engineering economics in both industrial engineering and civil engineering practice, the minimum acceptable rate of return, often abbreviated MARR, or hurdle rate is the minimum rate of return on a project a manager or company is willing to accept before starting a project, given its risk and the opportunity cost of forgoing other projects.

Maynard operation sequence technique (MOST) [1] is a predetermined motion time system that is used primarily in industrial settings to set the standard time in which a worker should perform a task. To calculate this, a task is broken down into individual motion elements, and each is assigned a numerical time value in units known as time ...
A blanket order, blanket purchase agreement or call-off order [1] is a purchase order which a customer places with its supplier to allow multiple delivery dates over a period of time, often negotiated to take advantage of predetermined pricing. It is normally used when there is a recurring need for expendable goods.
In the manufacturing batch production process, the machines are in chronological order directly related to the manufacturing process. The batch production method is also used so any temporary changes or modifications can be made to the product if necessary during the manufacturing process. [3]
The third step is to compute the predetermined overhead rate by dividing the estimated total manufacturing overhead costs by the estimated total amount of cost driver or activity base. Common activity bases used in the calculation include direct labor costs , direct labor hours , or machine hours.
