The following describes how to set or input cost and profit factors, which are the basic data for calculating ROI. As described above, the cost and benefit factors can be defined in various ways depending on the company or the type of work performed.

7 is a diagram illustrating a screen in which an interface for inputting a cost element for calculating ROI according to the present invention is actually implemented, and FIG. 8 is an actual implementation of an interface for input of a profit factor for calculating ROI according to the present invention. The figure illustrates an example of a screen.

As illustrated in FIG. 7, the setting or input of the cost element may be implemented together on the display screen for ROI inquiry, but is not limited thereto.

There is a part that can input the total construction cost of the project (task), and the display screen is implemented so that the cost factor can be input the other cost elements for the corresponding task. The cost element is transmitted to the ROI server 110 by each element input in advance, and the ROI server calculates the amount already spent or spent for the corresponding task.

FIG. 8 is a screen where an interface for inputting profit factors is actually implemented, and there is a portion capable of inputting a calculation factor for calculating profit factors for each task. As described above, it may be composed of labor time saving effect, business effect, and other profit factors, and if the preset value of each element is input in advance, the ROI server 110 may benefit according to the work content performed by the work terminal 100. Each element of the element is calculated and the total benefit element is calculated.

The cost factor may be calculated by, for example, inputting the construction cost of the system for performing the task in advance and in the case where the task performer performs the task in order to perform the task. .

The profit factor is, for example, the reduction of labor time by halving the actual cost factor when the task was previously reduced to one hour due to the introduction of profits and other relevant systems that the company actually obtained. And the like can be calculated.

The order in which the ROI calculation according to the present invention is made will be described with reference to the above components. 9 is a flowchart illustrating a process of calculating ROI according to the present invention.

First, an algorithm for inputting and calculating respective elements for calculating a cost element and a profit element for calculating an ROI is set in the ROI server 110 (S900). Each element and calculation algorithm is as described above.

When a business operator inputs a user authentication request to the work terminal 100 to perform a work through the work terminal 100, the work terminal 100 transmits a user authentication request to the ROI server 110 (S902). The server 110 processes the user authentication request and transmits a response to the user authentication to the work terminal 100 (S902).

When the task performer selects a task to be performed by the task terminal 100 (S906) and performs the selected task (S908), the task terminal 100 transmits the performance of the task to the ROI server 110.

The ROI server 110 calculates costs and benefits according to the predetermined cost and profit factors (S912), calculates an ROI according to the calculated costs and benefits (S914), and stores the ROI in the database 112 of the ROI server.

On the other hand, if you want to look up the ROI for each task first, when the query terminal 104 transmits a user authentication request signal to the ROI server 110 (S916), the ROI server 110 processes the user authentication for the user authentication request The response signal is transmitted to the inquiry terminal 104.

When the inquiry terminal 104 transmits an inquiry request signal of a specific task selected (S920), the ROI server 110 searches the database 112 for the ROI for the selected task and transmits the retrieved ROI to the inquiry terminal 104. (S922).

The above configuration and the process of calculating the ROI will be described, for example, when a base station maintenance worker of a mobile communication company performs a maintenance service of a base station. It moves and operates its own work terminal 100 for the repair of the base station. When the repairman drives the work application 102 of the work terminal 100 to detect an abnormal part of the base station, the user login request screen is displayed on the display screen of the work terminal 100 and the repairman enters his ID and password. Enter it. The input user login request is transmitted to the ROI server 110, and the processed user authentication request is transmitted to the work terminal 100. The maintenance staff selects the fault handling of the base station from the work contents displayed on the display screen of the work terminal 100 and performs a task such as radio wave detection for fault handling of the base station according to a function previously implemented in the work terminal 100. Detect. As a result of detection, a failure of RSSI (Received Signal Strength Indication) is detected and output adjustment is performed using an output adjustment function of a work terminal. The work application 102 included in the work terminal 100 records the work performance of the work performer and transmits the work to the ROI server 110. The ROI server 110 calculates a cost element and a benefit element of the base station's maintenance staff according to a predetermined cost factor and benefit factor calculation algorithm, and calculates an ROI according to the calculated cost element and the benefit element.

On the other hand, if you want to query the ROI for the base station repair, when the driving the inquiry application 106 included in the inquiry terminal 104, the user login request screen is displayed on the display screen of the inquiry terminal 100, the person who wants to look up the ROI Enter your ID and password. When the login request is processed by the ROI server 110 and received by the inquiry terminal 104, a screen for selecting work content is displayed on the display screen of the inquiry terminal 100. The inquirer can select the base station repair during the work and check the ROI of the base station repair service. In addition, you can inquire not only by task but also by the details of the work of a specific maintenance worker or a specific base station. In particular, the manager can easily consider that the base station maintenance work method is inefficient when the base station maintenance work of the current method is low ROI, and can consider improving the progress of the base station repair work. In addition, it can be used as an important data for management because it can immediately confirm that many problems occur only in a specific base station or that only certain maintenance personnel have low work efficiency.
