Knowledge point: value function evaluation formula

[Calculation of function realization cost] Calculation of cost index:

Cost index CI of the i-th evaluation object = actual cost Ci of the i-th evaluation object / total cost

[Calculation of function evaluation value]

Determine the functional evaluation value F = functional importance coefficient × target cost

[Calculation and analysis of functional value]

Functional cost method:

Value coefficient V of the i-th evaluation object = function evaluation value F of the i-th evaluation object / actual cost C of the i-th evaluation object

①V = 1. Indicates that the function evaluation value is equal to the function implementation cost. It indicates that the evaluation value object is the best and generally no improvement is needed.

②V <1. The implementation cost of this function is greater than the function evaluation value. Functions need to be improved to make the cost-to-function ratio more reasonable.

③V> 1. It shows that the function of this component is more important, that is, the actual cost of the function is lower than the function evaluation value.

Functional Index Method:

Value index of the i-th evaluation object VI = function index FI of the i-th evaluation object / cost index CI of the i-th evaluation object

①VI = 1. At this time, the function proportion of the evaluation object is roughly balanced with the cost proportion, and the reasonable matching can be considered, and the actual cost of the function is considered to be reasonable.

②VI <1. At this time, the cost ratio of the evaluation object is greater than its function weight. The evaluation object should be listed as the improvement object, and the improvement direction is mainly to reduce costs.

③VI> 1. At this time, the cost proportion of the evaluation object is smaller than its function proportion. There are three reasons for this. The first is that the actual cost is low, and the improvement direction should be increased costs. The second reason is that the object currently has more functions than it should have, and the improvement direction is to reduce the function level. The third reason is that the function is important but the cost is very small. Generally, this situation does not need to be listed as an improvement target.
