5 Alternative system scenarios to choose from

I have considered making alarm system, but considering that the alarm system is extremely impractical in computer application, this scheme has not passed.

6 Investment and Benefit analysis

6 . 1 expenditure

This software is only used to complete the course learning requirements, do not have to do business, no basic equipment and other expenses and do not consider the post-maintenance issues.

6 . 1. 1 Capital investment

A Houses and facilities: no fixed places, equipment for the crew of their respective computers;
b A DP device: none;
C Data communication equipment: none;
D Environmental protection equipment: none;
E Safety and confidentiality equipment: none;
F Software for ADP operating systems and applications: none;
G Database management software: none.

6 . 1. 2 Other disposable expenses

A Research (Research on research and design of requirements): none;
b Research on development plan and measurement benchmark: none;
C Establishment of the database: none;
D Conversion of ADP software: none;
E Cost of inspection and technical management: none;
F Training fee, travel and the one-time expenditure required for development and installation personnel: none;
G Retirement and transfer costs of personnel: none.

6 . 1. 3 Non-disposable expenses

6 . 2 Benefits

The software interface is simple, easy to operate, and it takes less time or almost no maintenance to maintain the latter.

6 . 2. 1 Disposable Income

A The design of the software memory is small, but also to achieve the functions of the general music player, so it is expected to be welcomed. If you have a cooperative relationship with the enterprise, you can use it as a direct benefit.

6 . 2. 2 Non-disposable benefits

In the operation of the whole system, the cost of maintenance personnel is reduced.

6 . 2. 3 Non-quantifiable benefits

This software is free software, do not want users to charge any fees. As the first work of this group, it is used only as a promotion.

6 . 3 yield/investment ratio

The profit/investment ratio for the entire system lifetime is 1.

6 . 4 Payback period

The cumulative number of proceeds begins to exceed the cumulative number of expenditures for a period of one months.

6 . 5 Sensitivity analysis

In the use of software, consider the possibility that a larger music library will affect the retrieval function of the software, resulting in slower processing speed.
