Determining time by cost

Software cost estimation is an important part of its system engineering economic analysis. It is not only the basis for selecting the best technical design solutions for software, but also the basis for software pricing.

Due to different time-specific economic purposes, the costs used for reviewing each design plan of the software should be the predicted costs, while the costs used for software pricing are the actual costs.

It still maintains its original form during use, but its value gradually decreases due to constant wear and tear. The part of the value of fixed assets expressed in currency that is reduced due to wear and tear is called fixed asset depreciation in accounting.

This part of the value that is gradually partially consumed and transferred to the product cost constitutes a production expense of the product cost. In accounting, it is called depreciation expense or depreciation amount.

Method used

It introduces a value coefficient that depends on function and cost to each subsystem of NIS, so that function/cost analysis can be performed and the target cost can be decomposed into each subsystem based on the value coefficient of each subsystem.

First, classify the objects to be inspected into ABC categories and select key inspection objects.

Then introduce some engineering economic parameters related to cost and schedule for each key object.

During the software development process, these engineering economic parameters are continuously observed, and corresponding measures are taken according to the status of these engineering economic parameters to achieve the purpose of cost control.

It is a method of project management used for comprehensive monitoring of project cost and progress.

Based on difference analysis

The basic idea of ​​earned value analysis method

is the monetary expression of value

For producers, the value of software is the value spent by the development organization in developing the software. Therefore, the price of the software product can use a certain amount of currency as compensation for the cost incurred by the development organization.

For consumers, software price is the amount of money paid to obtain software and services.
