An order winner is a set of criterion that differentiates the products or services of one firm from another. An order qualifier is a set of screening criteria that permits a firm’s products to be considered as possible candidates for purchase.

Trade-offs occur when activities are incompatible. Simply put, a trade-off means that more of one thing necessitates less of another.

Terms in this set (41) The process when a company seeks to match the benefits of a successful position while maintaining its existing position by adding new features, services, and technologies into its current portfolio is called flexibility.

One of the most widely used measures of productivity is Gross Domestic Product (GDP) per hour worked. This measure captures the use of labour inputs better than just output per employee.

Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time.

Multifactor productivity (MFP) is a measure of economic performance that compares the amount of output to the amount of combined inputs used to produce that output. Combinations of inputs can include labor, capital, energy, materials, and purchased services.

The basic benefit of increased productivity is that more output can be produced with the same quantity of inputswhile some inputs will be of improved quality or there can be changes in production arrangements. Alternatively, the same output can be produced with fewer resources.

You can measure employee productivity with the labor productivity equation: total output / total input. Let’s say your company generated $80,000 worth of goods or services (output) utilizing 1,500 labor hours (input). To calculate your company’s labor productivity, you would divide 80,000 by 1,500, which equals 53.

Change: subtract old value from new value. Example: You had 5 books, but now have 7. The change is: 7−5 = 2. Percentage Change is all about comparing old to new values.

The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it’s energy production or machine efficiency.

The watt is the unit of power. Power is the amount of energy transferred or consumed per unit of time; equivalently, power is the rate of doing work. In standard-speak, the watt is the power which in one second gives rise to energy of 1 joule.

a. An amount produced or manufactured during a certain time. b. The energy, power, or work produced by a system.

1. Basically the overall efficiency is based on the net output and input. Efficiency is the ratio of net work output to the input. The overall efficiency can be written as:
2. n = {(sum of inputs)—(sum of losses)}/(sum of inputs)
3. In case of thermodynamics, it is:
4. n = {(heat supplied)—(heat rejected)}/(heat supplied)

It is not possible to have an efficiency of greater than 1 or an efficiency percentage greater than 100%. This would mean that more energy is being transferred than is being supplied, which would mean that energy is being created. This would break the law of conservation of energy.

Mechanical efficiency (ηm) is described as the ratio between the power input (P) minus the mechanical power loss (PL.m) and the power input itself: Power loss refers primarily to the friction loss in pump bearings (e. g. plain and rolling element bearings) and shaft seals.

Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one.

The volumetric efficiency ηv [-] is defined as the ratio between the actual (measured) volume of intake air Va [m3] drawn into the cylinder/engine and the theoretical volume of the engine/cylinder Vd [m3], during the intake engine cycle.

Since a machine does not contain a source of energy, nor can it store energy, from conservation of energy the power output of a machine can never be greater than its input, so the efficiency can never be greater than 1.
