Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a system in which a plurality of entities sell merchandise or provide services related to merchandise, and comprehensively manage customer information managed by each entity using network communication.
[0002]
[Prior art]
A plurality of sales companies (entities) that handle products such as automobiles manage customer information such as names, addresses, and telephone numbers of customers of each sales company by individual information management systems. Further, each sales company provides information on new products and aftercare services to customers by direct mail (DM) or telephone based on customer information. As a result, the sales company can advertise the enhancement of its service to the customer, thereby promoting the reuse of the company by the customer when the customer buys a new product or requests repair of the product. In view of such circumstances, a system for issuing and managing a DM has been proposed (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP 2001-306789 A
[0004]
[Problems to be solved by the invention]
However, since customer information is "property" for each sales company, generally, customer information of one sales company is kept private to other sales companies. Therefore, even if a plurality of sales companies have information such as addresses for the same customer, the sales companies cannot know each other. For this reason, the sales company regularly mails the DM to an address different from the actual one, or continuously calls a telephone number different from the actual one, resulting in unnecessary postage and telephone charges. And the like.
[0005]
For example, consider a case in which a customer x purchases a product from a sales company A and then requests the sales company B to repair the product. In this case, (1) after purchasing the product from the sales company A, the customer x changes its base, and the address is changed from “XX prefecture ●● city ‥” to “△△ prefecture ▲▲ city” by the time of requesting repair of the product. To "", and the telephone number may be changed from "0 @ 1502" to "0 @ 1421". In addition, despite the fact that the address “XX prefecture ●● city 、” and the telephone number “0」 1502 ”have not changed since the purchase of the product, when the customer x temporarily returns home, When a repair request is made, a situation may be assumed in which the address of the parent's house “△△ Prefecture ▲▲ City”, the telephone number “0「 1421 ”, and the like are provided to the sales company B.
[0006]
In any of the above (1) and (2), according to the customer information held by the sales company A, the address, telephone number, etc. of the customer x are “XX prefecture ●● city ‥”, “0 ‥ 1502”, etc. On the other hand, according to the customer information held by the sales company B, the address, telephone number, and the like of the customer x are “△△ prefecture ▲ 市 city”, “0 ‥ 1421”, and the like.
[0007]
For the sales companies A and B, the customer information is a property, as described above, and is kept private. Therefore, if the customer x purchases the product from the sales company A and then requests the sales company B for repair of the product, the sales companies A and B each have the same information of the customer x. , Each other can not know the fact.
[0008]
For this reason, the sales company A continuously mails the DM assuming that the address and the telephone number of the customer x are “XX prefecture ●● city ‥”, “0 ‥ 1502”, etc. Or call it. Similarly, the sales company B continuously mails the DM or assumes that the address, telephone number, etc. of the customer x are "△△ prefecture ▲ city ~", "0 ‥ 1421", etc. Or
[0009]
However, in the case of (1), since the actual address of the customer x is different from the information held by the sales company A, the DM mail and the telephone call to the customer x by the sales company A are useless. . In the case of (2), since the actual address of the customer x is different from the information held by the sales company B, the DM mail and the telephone call to the customer x by the sales company B are useless. . As a result, useless postage and telephone charges are incurred for the sales companies A and B as described above. If the number of customers increases, such wasteful costs naturally become enormous, which is a serious problem for a sales company.
[0010]
In view of the above, the present invention provides a system capable of appropriately comprehensively managing customer information of a plurality of entities from the viewpoint of wasteful cost savings caused by redundantly retaining customer information by a plurality of entities. And
[0011]
[Means for Solving the Problems]
A customer information management system according to the present invention for solving the above-mentioned problems includes a product identifier assigned to each product for identifying an individual product, a customer identifier for identifying an individual customer, and a contact address of the customer. Information acquiring means for acquiring customer information managed by a plurality of first entities from a terminal of the first entity via a network, and a customer acquired from the terminal of the first entity by the information acquiring means. Information registration means for registering information in association with the first entity; and, for the product identifier, the same customer information as the new entity information of the second entity acquired from the terminal of the second entity by the information acquisition means. Means for determining whether the product identifier is registered or unregistered by the means, and new customer information for the product identifier by the first determination means. When it is determined that the same customer information is already registered, a second determination unit that determines whether the new customer information and the registered customer information are the same for the customer identifier and the contact information, and a second determination. When it is determined by the means that the new customer information and the registered customer information are different from each other with respect to the customer identifier or the contact information, the information registration means registers the terminal of the first entity registered in association with the registered customer information. On the other hand, among the customer information managed by the first entity, first identification information for identifying which registered customer information is determined to be different from the new customer information with respect to customer identifier or contact information, Information providing means provided via a network.
[0012]
According to the present invention, first, it is determined whether or not the same customer information as the customer information (new customer information) newly managed by the second entity has been registered for the “product identifier”. (First judgment).
[0013]
If it is determined in the first determination that the same customer information as the new customer information has already been registered for the product identifier, then the new customer information and the registered customer information for the “customer identifier” and “customer contact information” Is determined (second determination).
[0014]
If it is determined in the second determination that the customer information is different from the customer identifier or the contact information, the terminal of the first entity that individually manages the registered customer information is managed by the first entity. “First specifying information” for specifying which of the registered customer information is the provided customer information is provided.
[0015]
The fact that the first specific information has been provided to the terminal of the first entity means that a plurality of pieces of customer information that are the same for the “product identifier” and different for one of the “customer identifier” and the “contact information of the customer” Means managed by each entity. The fact that customer information that differs only in the “customer identifier” is managed by a plurality of entities means that a person who was a customer of the first entity can send a product to another person (typically a family member or cohabitant) having the same contact information. Is transferred, meaning that the other party is likely to be a new customer of the second entity. In addition, the fact that customer information having only a difference in “contact information” is managed by a plurality of entities means that the contact information of the customer who was the customer of the first entity fluctuates, and the contact information after the change changes the contact information of the first entity. This means that the customer was likely to be a new customer of the second entity. Therefore, there is a high possibility that the first entity will be wasted even if the DM is continuously mailed to the customer.
[0016]
In view of such circumstances, the first entity determines which customer information has been provided with the "first specific information" through the terminal, and who may be wasted when the DM is mailed or the like. Can be grasped. Then, the first entity confirms the location of the customer based on the customer information managed by the first entity, and based on the confirmation work, can determine whether or not the DM should be continuously mailed to the customer. . This work is significantly less burdensome than checking the locations of all customers, including those who are likely to have not relocated.
[0017]
Therefore, according to the present invention, the first entity can omit unnecessary mailing of the DM to the customer, and can save unnecessary cost related to the mailing.
[0018]
Also, the first entity and the second entity do not directly exchange each other's personal information, and the personal information of the customer can be kept secret and mutually protected.
[0019]
Also, according to the present invention, the information providing means may release, from the terminal of the first entity to which the first specific information has been provided, the specification of the registered customer information based on the first specific information according to the operation of the terminal by the first entity. When the information is obtained by the information obtaining means via the network, the specification of the first entity among the customer information managed by the second entity for the terminal of the second entity is canceled by the first specific information. It is characterized in that second specifying information for specifying the customer information is provided via a network.
[0020]
According to the present invention, if the first entity determines that it is meaningful to continuously mail a DM to the customer associated with the first specific information, the first entity uses the first specific information at the terminal. Can be canceled. In response, the terminal of the second entity specifies which of the customer information managed by the second entity is the customer information for which the specification by the first specification information has been canceled. Information "is provided.
[0021]
The fact that the second specific information is provided to the terminal of the second entity means that a plurality of pieces of customer information that are the same for the “product identifier” and different for one of the “customer identifier” and the “contact information of the customer” Means that the customer information is determined to be unnecessary by the first entity by the first specific information. The cancellation of the specification of the customer information by the first specific information by the first entity means that it is determined by the first entity that mailing a DM to the customer based on the customer information is meaningful. This means that it is highly likely that the second entity will waste mailing the DM to the customer based on the customer information. For this reason, it is highly likely that the second entity is wasted even if the DM is mailed to the customer.
[0022]
In view of such circumstances, the second entity determines which customer information has been provided with the "second specific information" through the terminal, and who may be wasted if the DM is mailed or the like. Can be grasped. Then, the second entity confirms the location of the customer based on the customer information managed by the second entity, and based on the confirmation work, can determine whether or not the DM should be continuously mailed to the customer. . This work is significantly less burdensome than checking the locations of all customers, including those who are likely to have not relocated.
[0023]
Therefore, the second entity can omit unnecessary mailing of the DM to the customer, and can save unnecessary costs related to the mailing.
[0024]
Further, according to the present invention, when the information registering means determines that the new customer information and the registered customer information are different from each other with respect to the customer identifier or the contact information by the second determining means, the information associated with the first entity up to that time is determined. Instead of the registered customer information, the new customer information is registered in association with the second entity.
[0025]
As described above, the fact that the new customer information and the registered customer information differ for the customer identifier or the contact information by the second determination means means that the person who was the customer of the first entity is the new customer of the second entity. Means that the first entity is highly likely to be wasted even if the first entity mails the DM to the customer. Therefore, mailing the DM to the customer based on the customer information managed by the second entity rather than the customer information managed by the first entity can save the mailing and the like. High in nature.
[0026]
According to the present invention, in this case, instead of the customer information associated with the first entity by the information registration unit, the customer information newly managed by the second entity is associated with the second entity. Registered at. Therefore, only the customer information which is highly unlikely to be wasted when the DM is mailed to the customer can be registered by the information registration means.
[0027]
Further, the present invention provides a method in which the first determining means determines that the same customer information as the new customer information has not been registered for the product identifier, or the second determining means determines whether the new customer information and the contact information correspond to the new customer information and the registered customer information. A third determining unit that determines whether the same customer information as the new customer information is registered or unregistered with respect to the customer identifier and the contact information when the information is different from the information. When the third determining means determines that the same customer information as the new customer information has not been registered for the customer identifier or the contact information, the new customer information is registered in association with the second entity. I do.
[0028]
According to the present invention, when it is determined that the same customer information as the new customer information has not been registered for the “customer identifier” or “contact information”, the customer is completely new and the customer information is registered by the information registration means. Probability is not high. In this case, the new customer information is registered by the information registration means. Therefore, when the customer information newly managed by the second entity is highly likely to be unregistered new customer information, the customer information can be registered by the information registration unit.
[0029]
Further, in the present invention, the third determining means determines whether the same customer information as the new customer information has been registered or not registered for the customer name as the customer identifier and the customer telephone number as the contact information. It is characterized by determining.
[0030]
Further, in the present invention, the customer information identical to the new customer information has already been registered by the information registering means for the customer name as the customer identifier and the customer telephone number as the contact information of the customer. Or unregistered.
[0031]
ADVANTAGE OF THE INVENTION According to this invention, customer information can be managed appropriately from a viewpoint of cost saving, such as mailing of useless DM by an entity, based on a customer's name and telephone number.
[0032]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a customer information management system according to the present invention will be described with reference to the drawings.
[0033]
FIG. 1 is an explanatory diagram of a configuration of a customer information management system according to an embodiment of the present invention, and FIGS. 2 to 6 are explanatory diagrams of functions of a customer information management system according to an embodiment of the present invention.
[0034]
The customer information management system shown in FIG. 1 includes a server 10 connected to a plurality of entity terminals 20 (including a first entity terminal 21 and a second entity terminal 22) via a network so as to be able to communicate with each other. Have been. One or more servers 10 constituting the customer information management system of the present invention may be used.
[0035]
The customer information management system includes an information acquisition unit 11, an information registration unit 12, a first determination unit 13, a second determination unit 14, a third determination unit 15, and an information providing unit 16.
[0036]
The information acquisition unit 11 acquires “customer information” managed by each entity using the terminal 20 from each terminal 20 via a network. The customer information includes at least a product number (product identifier) assigned to the product to identify each product, a customer name (customer identifier), and a customer address and telephone number (contact information). . Hereinafter, information acquisition by the information acquisition unit 11 is referred to as “reception” of information by the server 10 or “transmission” of information to the server 10.
[0037]
The information registration unit 12 registers the customer information received by the server 10 in association with each entity that is the transmission source, based on the determination result by the first determination unit 13 and the like as described later.
[0038]
The first determination unit 13 determines whether the same customer information as the new customer information of the second entity transmitted from the terminal 22 of the second entity to the server 10 has been registered by the information registration unit 12 or has not been registered for the “article number”. Is determined.
[0039]
When the first determination unit 13 determines that the same customer information as the new customer information has been registered for the “product number” by the first determination unit 13, the new customer information for the “customer name” and “telephone number” And whether the registered customer information is the same.
[0040]
The third determination unit 15 determines whether the first determination unit 13 determines that the same customer information as the new customer information has not been registered for the “product number”, or the second determination unit 14 determines “customer name” and “telephone number”. Is determined to be different between the new customer information and the registered customer information, it is determined whether the same customer information as the new customer information has been registered or unregistered for “customer name” and “telephone number”. .
[0041]
The information providing unit 16 provides the “first specific information” to the terminal 21 of the first entity via the network under a predetermined condition, and provides the “second specific information” to the second terminal via the network under another predetermined condition. It is provided to the terminal 22 of the entity. Hereinafter, information provision by the information provision unit 16 is referred to as “transmission” by the server 10 or “reception” from the server 10.
[0042]
The function of the customer information system having the above configuration will be described with reference to FIGS.
[0043]
The “customer information” managed by each entity is transmitted to the server 10 from the terminals 20 of a plurality of entities in advance (arrow (1) in FIG. 2). Which of the customer information managed by the entity is transmitted to the server 10 can be selected by the terminal 20 of the entity. The customer information received by the server 10 can be registered by the information registration unit 12 so that customer information regarding the same customer is not duplicated. As shown in FIG. 4, customer information p1, p2,..., Pn of the first entity and customer information q1, q2,..., Qm of the second entity are registered as comprehensive recorded customer information by the information registration unit 12. You.
[0044]
When the second entity obtains a new customer and manages the customer information as new customer information (see FIG. 5q0), “new customer information” is transmitted from the terminal 22 of the second entity to the server 10. (Arrow (2) in FIG. 2).
[0045]
In response to this, first, whether or not the same customer information as the customer information (new customer information) newly managed by the second entity has been registered for the “article number” by the first determination unit 13. Is determined (first determination / s1 in FIG. 3).
[0046]
If it is determined in the first determination that the same customer information as the new customer information has been registered for the product number (YES in s1 in FIG. 3), then the new customer information for “customer name” and “customer phone number” It is determined whether or not this is the same as the registered customer information (second determination / s2 in FIG. 3).
[0047]
Then, when it is determined in the second determination that either of the customer name and the telephone number is different from each other (one-sided match), the information registration unit 12 registers the information previously associated with the first entity. Instead of customer information, new customer information is registered in association with the second entity (s3 in FIG. 3). For example, if the customer information p2 (see FIG. 4) registered in association with the first entity is determined in the second determination to be different from the new customer information q0 for either the customer name or the telephone number, The customer information q0 is registered in association with the second entity (see FIG. 5).
[0048]
Also, in this case, the terminal 21 of the first entity that individually manages the registered customer information specifies which of the customer information managed by the first entity is the registered customer information. The "first specific information" is transmitted from the server 10 (arrow {3} in FIG. 2, s4 in FIG. 3). Accordingly, the first identification information x1 for identifying the registered customer information p2 among the registered customer information p1, p2,..., Pn managed by the first entity is stored in the terminal 21 of the first entity. (See FIG. 5).
[0049]
If the first entity determines that it is meaningful to continuously mail the DM to the customer related to the first specific information, the first entity cancels the specification of the customer information by the first specific information at the terminal 21. . For example, the first specific information x1 illustrated in FIG. 5 disappears in the terminal 21 of the first entity in response to a click operation.
[0050]
In response, the information registration unit 12 registers the new customer information in association with the second entity instead of the registered customer information previously associated with the first entity (s6 in FIG. 3). For example, when the specification of the registration information p2 by the first specification information x1 (see FIG. 5) is released, the customer information p2 is registered again in association with the first entity (see FIG. 6).
[0051]
Further, the release information is transmitted from the terminal 21 of the first entity to the server 10 (arrow 4 in FIG. 2). Further, the server 10 specifies to the terminal 22 of the second entity which of the customer information managed by the second entity is the customer information for which the identification by the first identification information has been canceled. "Specific information" is provided (arrow 5 in FIG. 2, s7 in FIG. 3). As a result, of the customer information q0, q1,..., Qm managed by the second entity, the second specifying information x2 for specifying which customer information q0 is displayed on the terminal 22 of the second entity. (See FIG. 6).
[0052]
Here, returning to the determination by the first determination unit 13 and the second determination unit 14 again, the description of the functions of the present system will be continued.
[0053]
If it is determined in the second determination that both the “customer name” and the “telephone number” match, the registration state of the customer information is maintained as it is.
[0054]
Further, when it is determined that the same customer information as the new customer information has not been registered for the “product number” in the first determination (NO in s1 in FIG. 3), or in the second determination, “customer name” and “telephone number” Are not the same, the third determination unit 15 determines whether the same customer information as the new customer information has been registered for “customer name” and “telephone number” (s8 in FIG. 3). ).
[0055]
In the third determination, when it is determined that the same customer information as the new customer information has been registered for “customer name” and “telephone number” (YES in s8 in FIG. 3), the registration state of the customer information is maintained as it is. . On the other hand, if it is determined in the third determination that the same customer information as the new customer information for “customer name” and “telephone number” has not been registered, the new customer information is stored in the second entity by the information registration unit 12. It is newly registered in association with it (s9 in FIG. 3).
[0056]
According to the customer information management system of the present invention, the provision of the first specific information to the terminal 21 of the first entity (see the arrows {3}, 3s4, and 5x1 in FIG. 2) is the same for the “article number”, and This means that customer information different for one of “customer name” and “telephone number” is managed by the first and second entities, respectively. The fact that the first and second entities manage customer information that differs only in the “customer name” means that the customer who was the customer of the first entity has the same contact information as another person (typically a family member or a cohabitant). ) Means that the other party is likely to be a new customer of the second entity. Further, the fact that customer information having only a “phone number” is managed by the first and second entities means that the contact information of the customer who was the customer of the first entity fluctuates, and This means that a person who was a customer of the entity is likely to be a new customer of the second entity. For this reason, it is highly likely that the first entity will be wasted if the DM is continuously mailed to the customer.
[0057]
In view of such circumstances, the first entity determines which customer information has been provided with the “first specific information” through the terminal 21, and a customer who may be wasted when the DM is mailed or the like. It is possible to know who it is (see FIG. 5x1). Then, the first entity confirms the location of the customer based on the customer information managed by the first entity, and based on the confirmation work, can determine whether or not the DM should be continuously mailed to the customer. . This work is significantly less burdensome than checking the locations of all customers, including those who are likely to have not relocated.
[0058]
Therefore, the first entity can omit useless mailing of the DM and the like to the customer, and can save unnecessary cost related to the mailing and the like.
[0059]
Also, the first entity and the second entity do not directly exchange each other's personal information, and the personal information of the customer can be kept secret and mutually protected.
[0060]
In addition, if the first entity determines that it is meaningful to continuously mail the DM to the customer relating to the first specific information, the first entity determines the customer information by the first specific information at the terminal 21. It can be released (see FIG. 5 × 1, FIG. 6). In response to this, the terminal 22 of the second entity specifies which of the customer information managed by the second entity is the customer information whose specification by the first specific information has been canceled. "Specific information" is provided (see arrow 5 in FIG. 2, FIG. 3s7, and FIG. 6x2).
[0061]
The fact that the second specific information has been provided to the terminal 22 of the second entity is the same for the “article number” and the customer information different for one of the “customer name” and the “telephone number” is the first and second customer information. It means that the two entities are respectively managed, and that the first entity has determined that the identification of the customer information based on the first identification information is unnecessary. The cancellation of the specification of the customer information by the first specific information by the first entity means that it is determined by the first entity that mailing a DM to the customer based on the customer information is meaningful. This means that it is highly probable that the second entity mails a DM to the customer based on the customer information. For this reason, it is highly likely that the second entity is wasted even if the DM is mailed to the customer.
[0062]
In view of such circumstances, the second entity determines which customer information has been provided with the "second specific information" through the terminal, and which customer may be wasted when the DM is mailed. (See FIG. 6x2). Then, the second entity confirms the location of the customer based on the customer information managed by the second entity, and based on the confirmation work, can determine whether or not the DM should be continuously mailed to the customer. . This work is significantly less burdensome than checking the locations of all customers, including those who are likely to have not relocated.
[0063]
Therefore, the second entity can omit unnecessary mailing of the DM to the customer, and can save unnecessary costs related to the mailing.
[0064]
In the above embodiment, “name” is adopted as the “customer identifier”, but “birth date”, “occupation”, etc. may be adopted in addition to or instead of “name” in other embodiments. . In the above embodiment, “telephone number” is adopted as “contact information”. However, in another embodiment, “address”, “zip code”, “e-mail address” in addition to or instead of “telephone number” is used. "May be adopted.
