Description

FIELD

The embodiments discussed herein are related to an operator evaluation support device and an operator evaluation support method for supporting evaluation of an operator at a call center.

BACKGROUND

In recent years, importance has been placed on improving the quality of an operator's telephone calls at call centers. The evaluation of the call quality of an operator is made by, for example, a supervisor controlling the operators. As one viewpoint of evaluating the call quality, for example, there is the length of the call time.

In the conventional technology, examples of an index for determining whether an appropriate service has been provided to the customer (i.e., customer satisfaction) are the length of time the customer has waited for his call to be taken, the number of times the customer's call has been transferred, and the time length of silence of the customer (see Patent Document 1).

By using the length of time the customer has waited for his call to be taken, the number of times the customer's call has been transferred, and the time length of silence of the customer, the supervisor estimates the customer's psychological state, and determines the customer satisfaction.

However, in addition to determining the customer satisfaction of a customer with respect to each operator, the supervisor is also to grasp whether the operator's response to the customer is appropriate. There is known the following conventional technology of evaluating the operator's response to the customer.

For example, the average time per call is calculated based on the time length of all of the calls with customers; the time of a call between an operator and a customer, which is an evaluation target, is compared with the average time; and the service skills of the operator are estimated (see Patent Document 2).

Alternatively, time information of a service sequence when servicing the customer is received for each operation task, the service time according to the operation task is estimated based on the time information for each of a plurality of service sequences, and the operation skill of the operator is estimated based on the estimated service time (see Patent Document 3).

However, even if the supervisor recognizes that there is a problem in the call between an operator and a customer due to the difference between the service time and the average service time of all operators, the supervisor is unable to easily find the portion of a problem in a call from a customer attended to by an operator.

That is to say, the supervisor is to appropriately supervise how the operator is to make services, based on the evaluation on the operator as described above. Therefore, the supervisor is to confirm the factor causing the call to exceed the average service time. However, unless the call record is played, the supervisor does not know the specific contents of the call. Furthermore, even when the call is played, the supervisor is to sequentially listen to the call from the beginning, because the supervisor is unaware of where the problem is in the call. This confirmation method is time-consuming and inefficient. Thus, there have been cases where the supervisor is unable to sufficiently confirm the contents of the call, and consequently incapable of giving appropriate supervision.

The server 1 is connected to the operator terminal 2, the administrator terminal 3, and the customer terminal 4 via a predetermined network such as the Internet, a LAN (Local Area Network), and a public network.

The server 1 includes a customer DB 11, a question DB 12, a FAQ DB 13, a product DB 14, an operator DB 15, a voice DB 16, a speech time DB 17, a manual DB 18, a page switch DB 19, an evaluation DB 20, a call program 21, an OP (operator) evaluation program 22, and an information search program 23. Furthermore, the operator terminal 2 includes an operator program 31. The administrator terminal 3 includes an administrator terminal program 41. The administrator terminal 3 is operated by a supervisor, who is an example of the administrator.

The server 1 executes the call program 21, the OP evaluation program 22, and the information search program 23. By executing the call program 21, the server 1 connects with the customer terminal 4 and the operator terminal 2, records calls, and sends information of the customer to the operator terminal 2.

Furthermore, by executing the OP evaluation program 22, the server 1 creates information used by the supervisor for evaluating the operator, and sends information used by the supervisor for evaluating the operator to the administrator terminal 3.

Furthermore, by executing the information search program 23, the server 1 searches the manual DB 18 for information, sends the search results to the operator terminal 2, and records the contents of the information sent to the operator terminal 2 and the times at which the information is displayed and hidden at the operator terminal 2.

The operator terminal 2 executes the operator program 31. By executing the operator program 31, the operator terminal 2 displays information of the customer received from the server 1, and displays the search results of the information from the manual DB 18. The administrator terminal 3 executes the administrator terminal program 41. By executing the administrator terminal program 41, the administrator terminal 3 displays information used by the supervisor for evaluating the operator, which has been received from the server 1. Note that the customer terminal 4 may be any device having a telephone function, such as a telephone, and a PC having a telephone function.

The customer DB 11 records information relevant to the customer. The question DB 12 records information relevant to inquiries from the customer. The FAQ DB 13 records information relevant to FAQ (Frequently Asked Questions). The product DB 14 records information relevant to products.

The operator DB 15 records information relevant to the state of the operator (attending to a call, available, etc.). The voice DB 16 records information relevant to a voice file. The speech time DB 17 records information relevant to the speech of the customer and the operator, such as the timing of the speech of the customer and the operator.

The manual DB 18 records the screen data and the standard duration of each section (page) of the manual. The page switch DB 19 records information relevant to the operation of displaying or the hiding of the manual performed by the operator. The evaluation DB 20 records information relevant to the evaluation based on the difference between the standard duration and the actual duration.

FIG. 2 is a hardware configuration diagram of the server. The server 1 illustrated in FIG. 2 includes an input device 51, a display device 52, and a main body 53. The main body 53 includes a main storage 61, a processor 62, an interface device 63, a recording medium reading device 64, and a secondary storage 65, which are interconnected by a bus 67. The input device 51 and the display device 52 are connected to the bus 67.

The input device 51, the display device 52, the main storage 61, the processor 62, the interface device 63, the recording medium reading device 64, and the secondary storage 65, which are interconnected by the bus 67, may exchange data with each other under the control of the processor 62. The processor 62 is a CPU (Central Processing Unit) that controls the operations of the entire server 1.

The interface device 63 receives data from the operator terminal 2, the administrator terminal 3, and the customer terminal 4, and passes the contents of the data to the processor 62. Furthermore, the interface device 63 sends data to the operator terminal 2, the administrator terminal 3, and the customer terminal 4 according to instructions from the processor 62.

The secondary storage 65 stores an operator evaluation support program that causes a computer to perform a process in at least the operator evaluation support device, as part of the program for causing the server 1 to exhibit the same functions as the operator evaluation support device. The operator evaluation support program includes the call program 21, the OP evaluation program 22, and the information search program 23.

Then, as the processor 62 reads the operator evaluation support program from the secondary storage 65 and executes the operator evaluation support program, the server 1 functions as an operator evaluation support device. The operator evaluation support program may be stored in the main storage 61 accessible by the processor 62. The input device 51 receives input of data under the control of the processor 62. The operator evaluation support program may be recorded in a recording medium 66 readable by the server 1.

The recording medium 66 readable by the server 1 may be a magnetic recording medium, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording medium are a HDD, a flexible disk (FD), and a magnetic tape (MT). Examples of an optical disk are a DVD (Digital Versatile Disc), a DVD-RAM, a CD-ROM (Compact Disc-Read Only Memory), and a CD-R (Recordable)/RW (ReWritable). An example of a magneto-optical recording medium is a MO (Magneto-Optical disk).

When distributing the operator evaluation support program, for example, a portable recording medium 66 such as a DVD and a CD-ROM recording the operator evaluation support program may be sold.

For example, in the server 1 executing the operator evaluation support program, the recording medium reading device 64 reads the operator evaluation support program from the recording medium 66 recording the operator evaluation support program. The processor 62 stores the read operator evaluation support program in the main storage 61 or the secondary storage 65. The server 1 reads the operator evaluation support program from the main storage 61 or the secondary storage 65 that is a storage device included in itself, and executes a process in accordance with the operator evaluation support program.

FIG. 15 is a flowchart of a process according to the call program 21. In step S1, the call receiving unit 105 of the server 1 waits until a call is received from the customer terminal 4. When a call is received from the customer terminal 4, the call receiving unit 105 generates a call ID in step S2.

In step S3, the operator determining unit 104 refers to the operator DB 15, and determines whether there is an operator whose “status” data item is not “attending to a call” (available). When there is no operator who is not “attending to a call”, in step S4, the operator determining unit 104 places the customer from which a call is received in a queue.

Then, the operator determining unit 104 waits until it is determined that there is an operator who is not “attending to a call”. When the operator determining unit 104 determines that there is a operator who is not “attending to a call”, the call connection unit 103 selects one operator who is not “attending to a call”, and connects the operator terminal 2 of the selected operator with the customer terminal 4 (step S5).

In step S6, the operator determining unit 104 sets the “status” data item of the selected operator in the operator DB 15 to “attending to a call”. Then, in step S7, the call connection unit 103 starts to record the call. The recording process of step S8 is executed after the recording of the call is started.

When the recording of the call is started, in step S9, the customer information acquiring unit 102 acquires information of the customer based on the telephone number of the call from the customer DB 11. The customer information sending unit 101 sends the information of the customer to the operator terminal 2.

In step S10, the operator determining unit 104 waits until the call ends. When the call ends, in step S11, the operator determining unit 104 adds a record relevant to the ended call to the question DB 12. In step S12, the operator determining unit 104 sets the data item “status” of the operator whose call has ended in the operator DB 15 as available. In step S13, the call connection unit 103 closes the voice file. In step S14, the call connection unit 103 registers, in the voice DB 16, a record relevant to the voice file of the ended call.

FIG. 16 is a flowchart of a recording process. In step S21, the call connection unit 103 opens a voice file. In step S22, the customer voice recording unit 106 sets the speech state of the customer as “no speech”. The OP voice recording unit 107 sets the speech state of the operator as “no speech”. In step S23, it is determined whether the call has ended, and the customer voice recording unit 106 and the OP voice recording unit 107 repeat steps S24 through S26 until the call ends.

In step S24, the customer voice recording unit 106 receives 20 milliseconds of the voice data of a customer among the voice data of the customer that has been cut by the voice cutting unit 108, and writes the received voice data in the voice file. The OP voice recording unit 107 receives 20 milliseconds of the voice data of an operator among the voice data of the operator that has been cut by the voice cutting unit 108, and writes the received voice data in the voice file.

In step S25, the customer voice recording unit 106 performs an operator speech confirmation process described below, confirms the speech start time and the speech end time of the operator, and writes the speech start time and the speech end time in the speech time DB 17. Furthermore, in step S26, the customer voice recording unit 106 performs a customer speech confirmation process described below, confirms the speech start time and the speech end time of the customer, and writes the speech start time and the speech end time in the speech time DB 17.

FIG. 17 is a flowchart of an operator speech confirmation process. In step S31, the OP voice recording unit 107 acquires the maximum sound volume (v1) of 20 milliseconds of the voice data of the operator.

In step S32, the OP voice recording unit 107 compares the maximum sound volume (v1) of the voice data of the operator with the sound volume (v0) determined as silent, and determines whether v1>v0 is satisfied.

When the OP voice recording unit 107 determines that v1>v0 is satisfied, the OP voice recording unit 107 determines whether the speech state of the operator is “no speech” in step S33. When the speech state of the operator is “no speech”, in step S34, the OP voice recording unit 107 records the present time as the speech start time of the operator, in the speech time DB 17.

In step S35, the OP voice recording unit 107 sets the speech state of the operator to “during speech”, and then ends the operator speech confirmation process of FIG. 17. When the speech state of the operator is not “no speech” in step S33, the OP voice recording unit 107 ends the operator speech confirmation process of FIG. 17.

When the OP voice recording unit 107 determines that v1>v0 is not satisfied, in step S36, the OP voice recording unit 107 determines whether the speech state of the operator is “during speech”. When the speech state of the operator is “during speech”, in step S37, the OP voice recording unit 107 records the present time as the speech end time of the operator in the speech time DB 17.

In step S38, the OP voice recording unit 107 sets the speech state of the operator to “no speech”, and then ends the operator speech confirmation process of FIG. 17. When the speech state of the operator is not “during speech” in step S36, the OP voice recording unit 107 ends the operator speech confirmation process of FIG. 17.

FIG. 18 is a flowchart of a customer speech confirmation process. In step S41, the customer voice recording unit 106 acquires the maximum sound volume (v1) of 20 milliseconds of the voice data of the customer.

In step S42, the customer voice recording unit 106 compares the maximum sound volume (v1) of the voice data of the customer with the sound volume (v0) determined as silent, and determines whether v1>v0 is satisfied.

When the customer voice recording unit 106 determines that v1>v0 is satisfied, in step S43, the customer voice recording unit 106 determines whether the speech state of the customer is “no speech”. When the speech state of the customer is “no speech”, in step S44, the customer voice recording unit 106 records the present time as the speech start time of the customer in the speech time DB 17.

In step S45, the customer voice recording unit 106 sets the speech state of the customer to “during speech”, and then ends the customer speech confirmation process of FIG. 18. When the speech state of the customer is not “no speech” in step S43, the customer voice recording unit 106 ends the customer speech confirmation process of FIG. 18.

When the customer voice recording unit 106 determines that v1>v0 is not satisfied, in step S46, the customer voice recording unit 106 determines whether the speech state of the customer is “during speech”. When the speech state of the customer is “during speech”, in step S47, the customer voice recording unit 106 records the present time as the speech end time of the customer in the speech time DB 17.

In step S48, the customer voice recording unit 106 sets the speech state of the customer to “no speech”, and then ends the customer speech confirmation process of FIG. 18. When the speech state of the customer is not “during speech” in step S46, the customer voice recording unit 106 ends the customer speech confirmation process of FIG. 18.

FIG. 19 is a flowchart of a process according to an information search program 23. In step S51, the information search receiving unit 116 determines whether a manual display request is received from the operator terminal 2.

When a manual display request is received, in step S52, the information searching unit 115 searches for information in line with the manual display request, in the manual DB 18. The information sending unit 114 sends the information in line with the manual display request to the operator terminal 2.

In step S53, the information searching unit 115 records, in the page switch DB 19, a record of information in line with the manual display request sent to the operator terminal 2 (for example, the time, a call ID, a manual ID, a section no., an operation), and then ends the process of the flowchart of FIG. 19.

Meanwhile, when the manual display request is not received, in step S54, the information searching unit 115 determines whether a manual hide request is received from the operator terminal 2. When a manual hide request is received, in step S55, the information searching unit 115 records, in the page switch DB 19, a record of information that has been hidden in line with the manual hide request (for example, the time, a call ID, a manual ID, a section no., an operation), and then ends the process of the flowchart of FIG. 19. When the manual hide request is not received, the information searching unit 115 ends the process of the flowchart of FIG. 19.

FIG. 20 is a flowchart of a process according to the OP evaluation program 22. In step S61, the speech selecting unit 113 waits until a speech display request is received from the administrator terminal 3. When a speech display request is received from the administrator terminal 3, in step S62, the speech selecting unit 113 sends a process range selection screen described below to the administrator terminal 3.

The administrator terminal 3 that has received the process range selection screen displays the process range selection screen described below and prompts the administrator to input selection information of the process range. The administrator terminal 3 sends the selection information of the process range input by the administrator, to the server 1. In step S63, the speech selecting unit 113 receives the selection information of the process range from the administrator terminal 3.

In step S64, the call status acquiring unit 112 acquires, from the question DB 12, a record of the first call ID corresponding to the selection information of the process range received from the administrator terminal 3.

In step S65, the call status acquiring unit 112 uses the operator ID included in the record acquired from the question DB 12 in step S64 to acquire an operator name from the operator DB 15.

In step S66, the call status acquiring unit 112 uses the first call ID corresponding to the selection information of the process range received from the administrator terminal 3, to acquire a start time and an end time of a section, from the page switch DB 19. The start time of the section is the time associated with the display operation. The end time of the section is the time associated with the hiding operation.

In step S67, the call status acquiring unit 112 acquires the manual ID and the section no. from the page switch DB 19, by using the first call ID corresponding to the selection information of the process range received from the administrator terminal 3. The call status acquiring unit 112 acquires, from the manual DB 18, the standard duration of the section displayed by the operator, by using the acquired manual ID and section no.

In step S68, the call status acquiring unit 112 sets, as the scheduled end time of the section, a value obtained by adding the standard duration to the start time of the section acquired in step S66.

In step S69, the call status acquiring unit 112 calculates the difference between the end time of the section acquired in step S66 and the scheduled end time of the section calculated at step S68.

In step S70, the call evaluating unit 111 acquires, from the evaluation DB 20, an evaluation point corresponding to the difference between the end time of the section calculated at step S69 and the scheduled end time of the section. In step S71, the call evaluating unit 111 adds a record to the speech table data (work)-section table described below.

In step S72, the call status acquiring unit 112 determines whether there is a next section. When there is a next section, the call status acquiring unit 112 performs the process starting from step S67 again.

When there is no next section, in step S73, the call evaluating unit 111 refers to the speech table data (work)-section table, and sets a value obtained by adding the evaluation points of all sections to the perfect 100 points, as the evaluation point of this call. Then, the call evaluating unit 111 creates the speech table data (work)-call summary information described below.

In step S74, the speech table creating unit 110 uses the first call ID corresponding to the selection information of the process range received from the administrator terminal 3, to acquire the start time and the end time of each speech from the speech time DB 17, and creates the speech table data (work)-speech time table described below.

In step S75, the speech table creating unit 110 performs a speech table creating process. In step S76, the speech table sending unit 109 sends the speech table to the administrator terminal 3 that received the speech table display request. In step S77, the call status acquiring unit 112 determines whether there is a record of the next call ID corresponding to the selection information of the process range received from the administrator terminal 3, in the question DB 12.

When there is a record of the next call ID, in step S64, the call status acquiring unit 112 acquires the record of the next call ID from the question DB 12, and performs the process of step S65 and onward. When there is no record of a next call ID, the call status acquiring unit 112 ends the process of the flowchart of FIG. 20.

FIG. 21 is an image diagram of a process range selection screen 200. The process range selection screen 200 is used by the administrator for inputting selection information of the process range. The process range selection screen 200 prompts the administrator to specify a call ID or to specify a condition (date range or operator ID), as the selection information of the process range.

FIG. 22 illustrates a configuration of a speech table data (work)-section table 201. The speech table data (work)-section table 201 includes data items such as a manual ID, a section no., a section summary, a section start time, a section end time, a scheduled section end time, and an evaluation point.

FIG. 23 illustrates a configuration of the speech table data (work)-call summary information 202. The speech table data (work)-call summary information 202 includes data items such as an evaluation point, an operator name, and a call time. The data item “evaluation point” is a value obtained by adding the evaluation points of all section points to the perfect 100 points.

FIG. 24 illustrates a configuration of a speech table data (work)-speech time table 203. The speech table data (work)-speech time table 203 includes data items such as the start time and the end time of each speech, and the speaker. The speech table data (work)-speech time table 203 is for recording the start time and the end time of each speech and the speaker in association with each other.

FIG. 25 is a flowchart of a speech table creating process. In step S81, the speech table creating unit 110 acquires an evaluation point and an operator name from the speech table data (work)-call summary information 202, and renders these items in the screen.

In step S83, the speech table creating unit 110 sequentially acquires records from the speech table data (work)-speech time table 203. In step S84, the speech table creating unit 110 determines whether the record has been acquired.

In step S86, the speech table creating unit 110 determines the size of a box (frame of speech) indicating the speech in the screen, based on the time of the speech (speech end time-speech start time). In step S87, the speech table creating unit 110 renders the frame of the speech in the screen.

In step S88, the speech table creating unit 110 acquires the next record from the speech table data (work)-speech time table 203. The speech table creating unit 110 repeats steps S84 through S88 until it is not possible to acquire the next record.

In step S84, the when the speech table creating unit 110 determines that it is not possible to acquire a record, in step S89, the speech table creating unit 110 sequentially acquires records from the speech table data (work)-section table 201. In step S90, the speech table creating unit 110 determines whether a record is acquired.

When a record is acquired, in step S91, the speech table creating unit 110 renders vertical lines at the positions of the section start time and the section end time. In step S92, the speech table creating unit 110 renders an arrow between the vertical lines rendered at step S91, and renders the section no. and the section summary.

In step S93, the speech table creating unit 110 renders a vertical dashed line at the position of the scheduled section end time. In step S94, the speech table creating unit 110 renders an arrow between the vertical line rendered at the position of the section start time and the dashed vertical line rendered at the position of the scheduled section end time, and renders the section no. and the standard duration.

In step S95, the speech table creating unit 110 performs a filling process. After the filling process, the speech table creating unit 110 performs the process of step S90. The speech table creating unit 110 repeats steps S90 through S95 until it is not possible to acquire a record. In step S90, when the speech table creating unit 110 determines that it is not possible to acquire a record, the process of the flowchart of FIG. 25 ends.

FIG. 26 is a flowchart of a filling process. In step S101, the speech table creating unit 110 determines whether the section end time has passed the scheduled section end time.

When the section end time has passed the scheduled section end time, in step S102, the speech table creating unit 110 acquires, from the speech table data (work)-speech time table 203, a record of a speech that has stared or ended between the scheduled section end time and the section end time.

In step S103, the speech table creating unit 110 determines whether a record has been acquired. When a record has been acquired, in step S104, the speech table creating unit 110 determines whether only the speech start time is included between the scheduled section end time and the section end time.

When only the speech start time is included between the scheduled section end time and the section end time, in step S105, the speech table creating unit 110 fills in the space between the speech start time and the section end time, with a color α.

When only the speech start time is not included between the scheduled section end time and the section end time, in step S106, the speech table creating unit 110 determines whether only the speech end time is included between the scheduled section end time and the section end time.

When only the speech end time is included between the scheduled section end time and the section end time, in step S107, the speech table creating unit 110 fills in the space between the scheduled section end time and the speech end time, with a color a.

When only the speech end time is not included between the scheduled section end time and the section end time, in step S108, the speech table creating unit 110 fills in the space between the speech start time and the speech end time, with a color a.

After the process of steps S105, S107, and S108, the speech table creating unit 110 performs the process of step S103 again. In step S103, when it is not possible to acquire a record, the process of the flowchart of FIG. 26 ends.

In step S101, when the section end time has not passed the scheduled section end time, in step S109, the speech table creating unit 110 determines whether the section end time is before the scheduled section end time.

When the section end time is before the scheduled section end time, in step S110, the speech table creating unit 110 acquires, from the speech table data (work)-speech time table 203, a record of a speech that has started or ended between the scheduled section end time and the section end time.

In step S111, the speech table creating unit 110 determines whether a record has been acquired. When a record has been acquired, in step S112, the speech table creating unit 110 determines whether only the speech start time is included between the scheduled section end time and the section end time.

When only the speech start time is included between the scheduled section end time and the section end time, in step S113, the speech table creating unit 110 fills in the space between the speech start time and the scheduled section end time, with a color β.

When only the speech start time is not included between the scheduled section end time and the section end time, in step S114, the speech table creating unit 110 determines whether only the speech end time is included between the scheduled section end time and the section end time.

When only the speech end time is included between the scheduled section end time and the section end time, in step S115, the speech table creating unit 110 fills in the space between the section end time and the speech end time, with a color β.

When only the speech end time is not included between the scheduled section end time and the section end time, in step S116, the speech table creating unit 110 fills in the space between the speech start time and the speech start time, with a color β.

After the process of steps S113, S115, and S116, the speech table creating unit 110 performs the process of step S111 again. In step S111, when it is not possible to acquire a record, the process of the flowchart of FIG. 26 ends.
