Description

The present invention relates to an information processing device, etc.

When building a system that meets customer requirements, developers such as SEs (System Engineers) and CEs (Customer Engineers) need to meet with the customer to properly understand the requirements that correspond to the operational services provided by the customer.

For example, when building a system, there are functional and non-functional requirements. Functional requirements are characterized by being directly linked to the business, easy to imagine, and stated in the customer's words, such as "I want to share and keep track of business hours on the system" or "I want to manage inventory linked to order information."

On the other hand, non-functional requirements, such as "responses within three lines" or "system downtime must be restored within three hours," are not directly related to business and are difficult for customers to notice. Identifying such non-functional requirements in advance requires skill, and is a difficult task even for experienced developers.

For this reason, a tool called "non-functional requirements grading" proposed by the Information-technology Promotion Agency (IPA) is used to prevent misunderstandings between customers and developers and understandings that differ from each other's intentions. The non-functional requirements grading comprehensively lists and classifies non-functional requirements items, and indicates the requirement level of each item in stages.

There is a conventional technology that supports developers by using non-functional requirement information created by the customer using a non-functional requirement grade. In this conventional technology, a component pattern is defined for each non-functional requirement, a component pattern corresponding to the customer's non-functional requirement information is extracted, and a network configuration diagram incorporating the extracted component pattern is created and displayed, thereby supporting developers. The developer uses the displayed network configuration diagram as a reference to build an operational system.

However, when building an operational system and providing operational services as described above, simply extracting component patterns is not sufficient.

For example, if some kind of failure occurs in an operational system, a workaround will be implemented to deal with the failure, but performing such a workaround manually is a heavy burden, so there is a need to further select automation parts that can perform the workaround automatically and incorporate them into the operational system. An automation part is a part (job) that defines the execution order of multiple code parts.

The number of code components used in automation parts is enormous, and the execution order of each code component varies depending on the operational system environment, so selecting additional automation parts is a heavy burden for developers.

In one aspect, the present invention aims to provide an information processing device, an information processing method, and an information processing program that can provide developers with information on automation parts suitable for an operational system.

In the first proposal, the information processing device has a service selection unit, a job selection unit, and an output unit. The service selection unit selects one operation service from a plurality of operation services each having a different degree of impact on society, based on non-functional requirements information of an operation system created using a non-functional requirements creation tool. The job selection unit selects a job that defines the interaction order of components that execute a specified process, based on the selected one operation service and information on the system's operation environment. The output unit outputs information on the selected job.

It makes it easy to understand the jobs to be incorporated into the operational system that is built based on non-functional requirements.

Below, examples of the information processing device, information processing method, and information processing program disclosed in the present application will be described in detail with reference to the drawings. Note that the present invention is not limited to these examples.

FIG. 1 is a diagram for explaining an example of processing of an information processing device according to this embodiment. The information processing device according to this embodiment uses non-functional requirement information 10 to identify information on automation parts to be incorporated into the operational system 5.

Non-functional requirement information 10 is information that is generated by the customer using a tool called "non-functional requirement grade," and non-functional requirement items are associated with selection levels. For example, non-functional requirement items include major items, medium items, and minor items, and a selection level of 1 to 5 is set for each minor item.

As an example, the selection levels for minor items (operation schedule) related to system operating hours and outage operations are as follows: selection level 1 (regular hours (9:00-17:00)), selection level 2 (outage only at night (9:00-21:00)), selection level 3 (outage of about an hour (9:00-8:00 the next morning)), selection level 4 (minor outage (9:00-8:55 the next morning)), and selection level 5 (uninterrupted 24 hours).

Here, there are three system levels for non-functional requirement grades according to their social importance. Specifically, there is system level (1) "a system with almost no social impact," system level (2) "a system with limited social impact," and system level (3) "a system with an extremely large social impact."

Depending on the system level, the selection level of the corresponding functional requirement item will differ and be defined in advance. For example, for system level (1), the selection level of the sub-item (operation schedule) will be "2." For system level (2), the selection level of the sub-item (operation schedule) will be "4." For system level (3), the selection level of the sub-item (operation schedule) will be "5." For the other sub-items, selection levels are defined according to each system level.

Meanwhile, components to be used in the operational system 5 are extracted based on the non-functional requirement information 10. In the example shown in FIG. 1, components 1-1, 1-3, 1-4, and 1-5 corresponding to the non-functional requirement information 10 are extracted from components 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, etc., and incorporated into the operational system 5. The process of extracting components based on the non-functional requirement information 10 may use any conventional technology. For example, the components are program modules that perform a specified process.

Returning to the explanation of the processing of the information processing device, the information processing device selects a corresponding operation service from operation services S1, S2, and S3 based on the selection level of the functional requirement item set in the non-functional requirement information 10. For example, operation service S1 is an operation service corresponding to system level (1). Operation service S2 is an operation service corresponding to system level (2). Operation service S3 is an operation service corresponding to system level (3).

Here, the selection level of the non-functional requirement items set in the non-functional requirement information 10 is the selection level corresponding to the system level (2), and the following processing will be described assuming that the information processing device selects the operational service S2.

The information processing device extracts automation parts corresponding to the selected operation service (operation service S2) and hearing sheet 20 based on the selected operation service (operation service S2) and hearing sheet 20, and sets them in the job list 30. The hearing sheet 20 sets environmental information (type of OS (Operating System)) of the operation system 5, workarounds, etc. The workarounds indicate the response to be taken when a malfunction occurs in the operation system 5.

For example, the information processing device selects the automation parts p1, p4, and p5 corresponding to the operation service S2 and the hearing sheet 20 from multiple automation parts p1, p2, p3, p4, p5, p6, etc., and sets information about the selected automation parts p1, p4, and p5 in the job list 30.

The developer refers to the job list 30 and incorporates the automation parts p1, p4, and p5 into the operation system 5. Note that the information processing device may automatically incorporate the automation parts p1, p4, and p5 set in the job list 30 into the operation system 5.

As described above, the information processing device according to this embodiment selects one operation service from a plurality of operation services that have different impacts on society based on the non-functional requirements information 10, and generates a job list 30 by selecting automation parts that correspond to the selected operation service and the hearing sheet 20. By referring to the job list 30, a developer can easily incorporate automation parts that correspond to customer requests into the operation system 5.

Next, an example of the configuration of an information processing device that executes the process described in FIG. 1 will be described. FIG. 2 is a functional block diagram showing the configuration of an information processing device according to this embodiment. As shown in FIG. 2, this information processing device 100 has a communication unit 110, an input unit 120, a display unit 130, a storage unit 140, and a control unit 150.

The communication unit 110 performs data communication with external devices, the operation system 5, etc., via the network. For example, the communication unit 110 is realized by a NIC (Network Interface Card) etc.

The input unit 120 is implemented using input devices such as a keyboard and a mouse, and inputs various information to the control unit 150 in response to input operations by the user.

The display unit 130 is realized by a display device such as a liquid crystal display. For example, the display unit 130 may display a job list 30 generated by the control unit 150.

The storage unit 140 has non-functional requirement information 10, a hearing sheet 20, a job list 30, a level determination table 141, and a job definition table 142. The storage unit 140 is realized, for example, by a semiconductor memory element such as a flash memory, or a storage device such as a hard disk or an optical disk.

Non-functional requirement information 10 is information that is generated by the customer using a tool called "non-functional requirement grade," and non-functional requirement items are associated with selection levels. Figure 3 is a diagram showing an example of the data structure of non-functional requirement information. For example, non-functional requirement information 10 includes non-functional requirement items, selection levels, etc. Non-functional requirement items include major items, medium items, and minor items. In addition, a selection level is set for each non-functional requirement item.

Customers use the "Non-functional requirements grade" tool proposed by the IPA to select the selection level that corresponds to the non-functional requirements item. In the example shown in Figure 3, the selection level that corresponds to the major item "Availability," the medium item "Continuity," and the minor item "Operation schedule" is selection level 4. Explanations of the other items and selection levels are omitted.

The hearing sheet 20 includes information about the customer's operational system environment and workarounds that are expected to be used in the operational system. For example, workarounds include processes such as "checking the CPU (Central Processing Unit) usage rate," "checking abnormal jobs → restarting the abnormal jobs," "checking the cluster status → switching clusters," "checking long-running jobs → contacting the customer → stopping," and "checking the service status of the Windows server."

The job list 30 is information generated by the control unit 150, and contains information on automation parts (jobs) to be incorporated into the customer's operational system. FIG. 4 is a diagram showing an example of the data structure of a job list. As shown in FIG. 4, the job list 30 associates item numbers, workaround names, and component linkage sequences. The item numbers are numbers that identify records in the job list 30. The workaround names are the names of workarounds. The component linkage sequence defines the execution sequence of code components for executing the corresponding workarounds. In the component linkage sequence, the code components are indicated by their code component numbers. The code component numbers are numbers that uniquely identify the code components. The code components are programs that execute processes such as "CPU operation check", "BIOS operation check", and "status check".

Code parts that are executed in the order of part interaction corresponding to a workaround (workaround name) correspond to one job (automation parts). For example, the automation parts related to the workaround "Check the service status of the Windows server" execute "code part with code part number A1", "code part with code part number B3", and "code part number C4" in that order. Note that the "part" in code part refers to the code part/software part, etc.

The level determination table 141 holds information used when determining the system level. FIG. 5 is a diagram showing an example of the data structure of the level determination table. As shown in FIG. 5, in this level determination table 141, the system level and the selection level of the system level for the non-functional requirement items are set.

Here, in the system-level selection level for non-functional requirement items, selection level values are set for the non-functional requirement items (major item, medium item, minor item). For example, for the major item "availability", the medium item "continuity", and the minor item "operation schedule", "selection level 2" is set for system level (1), "selection level 4" for system level (2), and "selection level 5" for system level 3. In the level determination table 141, selection levels are also set for the other non-functional requirement items at system levels (1), (2), and (3).

The job definition table 142 is a table that defines jobs that correspond to the system level, environmental information (type of OS (Operating System)) set in the hearing sheet 20, and workarounds. Figure 6 is a diagram showing an example of the data structure of a job definition table. As shown in Figure 6, this job definition table 142 associates item numbers, environments, workaround names, whether or not they are incorporated at the system levels (1) to (3), and the order of component linkage.

The item number is a number that identifies the record in the job definition table 142. The environment corresponds to the environmental information of the operational system. The workaround name is the name of the workaround. Incorporation at system level (1) to (3) indicates whether or not the automation parts of the corresponding workaround are incorporated at the corresponding system level (whether or not incorporation is recommended). If "O" is set, it indicates that the automation parts are incorporated, and if "O" is not set, it indicates that the automation parts are not incorporated.

For example, in item 1, the workaround name "Check CPU usage" is set to "O" for system levels (1) to (3). For this reason, when executing the workaround "Check CPU usage" in an operational system, it is recommended that the automated parts of the workaround "Check CPU usage" be incorporated into the operational system, regardless of the system level.

Meanwhile, in item 2, the workaround name "Check disk usage → Delete unnecessary files" is set to "O" for system levels (2) and (3), but is not set to "O" for system level (1). For this reason, when executing the workaround "Check disk usage → Delete unnecessary files" in an operational system, it is recommended that the automated parts of the workaround "Check disk usage → Delete unnecessary files" be incorporated into the operational system at system levels (2) and (3).

Returning to the explanation of FIG. 2, the control unit 150 has a reception unit 151, a service selection unit 152, a job selection unit 153, and an output unit 154. The control unit 150 is realized by a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 150 may also be executed by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

The reception unit 151 receives the non-functional requirement information 10 and the hearing sheet 20 from an external device (not shown), the input unit 120, etc. The reception unit 151 stores the received non-functional requirement information 10 and the hearing sheet 20 in the storage unit 140.

The service selection unit 152 selects a corresponding operation service from the operation services S1, S2, and S3 based on the non-functional requirement information 10 and the level determination table 141. The service selection unit 152 identifies the system level that corresponds to the selection level of the non-functional requirement item set in the non-functional requirement information 10. The service selection unit 152 outputs the selected operation service to the job selection unit 153.

The service selection unit 152 selects the operational service S1 if the selection level of the non-functional requirement item set in the non-functional requirement information 10 is the selection level of the non-functional requirement item corresponding to the system level (1) in the level determination table 141.

The service selection unit 152 selects the operational service S2 if the selection level of the non-functional requirement item set in the non-functional requirement information 10 is the selection level of the non-functional requirement item corresponding to the system level (2) in the level determination table 141.

The service selection unit 152 selects the operational service S3 if the selection level of the non-functional requirement item set in the non-functional requirement information 10 is the selection level of the non-functional requirement item corresponding to the system level (3) in the level determination table 141.

The job selection unit 153 selects jobs to be incorporated into the operation system based on the operation service selected by the service selection unit 152, the hearing sheet 20, and the job definition table 142, and generates a job list 30. As described above, the system level is determined according to the type of operation service.

For example, when the "Incorporate or not incorporate system-level automation parts corresponding to the operational service that correspond to the environmental information and workaround (workaround name)" in the job definition table 142 is "Yes", the job selection unit 153 extracts part-related information corresponding to the environmental information and workaround (workaround name) and sets it in the job list 30. When setting part-related information (job) in the job list 30, the job selection unit 153 associates the workaround name.

If the job definition table 142 indicates that the environment information and workaround (workaround name) corresponding to the operation service include system-level automation parts that are not "incorporated", the job selection unit 153 will not set part-related information for the corresponding workaround in the job list 30.

The job selection unit 153 repeatedly executes the above process for each workaround registered in the hearing sheet 20, thereby setting a job for each workaround in the job list 30.

The output unit 154 outputs the job list 30 generated by the job selection unit 153 to the display unit 130 for display. The output unit 154 may transmit the job list 30 to a specified external device. The output unit 154 may also obtain information on each automation component set in the job list 30 from a database, and output the information to the operation system to incorporate the automation component.

Next, an example of the processing procedure of the information processing device 100 according to this embodiment will be described. FIG. 7 is a flowchart showing the processing procedure of the information processing device according to this embodiment. The reception unit 151 of the information processing device 100 receives the non-functional requirement information 10 and the hearing sheet 20, and stores them in the memory unit 140 (step S101).

The service selection unit 152 of the information processing device 100 determines the system level based on the non-functional requirement information 10 and the level determination table 141 (step S102). The service selection unit 152 selects an operation service according to the system level (step S103).

The job selection unit 153 of the information processing device 100 selects a part interaction order (job) corresponding to the workaround set in the hearing sheet 20 based on the operation service (system level), the hearing sheet 20, and the job definition table 142 (step S104).

The job selection unit 153 associates the workaround name with the component linkage order and sets it in the job list (step S105). The output unit 154 of the information processing device 100 outputs the job list 30 (step S106).

Next, the effects of the information processing device 100 according to this embodiment will be described. The information processing device 100 selects one operation service from a plurality of operation services that have different impacts on society based on the non-functional requirement information 10, and generates a job list 30 by selecting automation parts that correspond to the selected operation service and the hearing sheet 20. By referring to the job list 30, a developer can easily incorporate automation parts in response to customer requirements into the operation system 5. For example, even an inexperienced developer can identify automation parts to be incorporated into the operation system in response to the non-functional requirement information.

The information processing device 100 selects one operation service from among a plurality of operation services based on the selection level of the non-functional requirement items set in the non-functional requirement information 10. This makes it possible to select an operation service that is appropriate for the social importance of the operation system of the non-functional requirement information 10.

The information processing device 100 selects jobs that correspond to the environmental information and workarounds of the operational system to generate a job list 30. This makes it possible to generate a list of automation parts to be incorporated into the operational system according to the non-functional requirement information, which can be referenced by the developer.

Next, an example of the hardware configuration of a computer that realizes the same functions as the information processing device 100 shown in the above embodiment will be described. FIG. 8 is a diagram showing an example of the hardware configuration of a computer that realizes the same functions as the information processing device of the embodiment.

As shown in FIG. 8, computer 200 has a CPU 201 that executes various types of arithmetic processing, an input device 202 that accepts data input from a user, and a display 203. Computer 200 also has a communication device 204 that transmits and receives data to and from external devices, etc., via a wired or wireless network, and an interface device 205. Computer 200 also has a RAM 206 that temporarily stores various types of information, and a hard disk device 207. Each of devices 201 to 207 is connected to a bus 208.

The hard disk device 207 has a reception program 207a, a service selection program 207b, a job selection program 207c, and an output program 207d. The CPU 201 also reads out each of the programs 207a to 207d and expands them in the RAM 206.

The reception program 207a functions as the reception process 206a. The service selection program 207b functions as the service selection process 206b. The job selection program 207c functions as the job selection process 206c. The output program 207d functions as the output process 206d.

The processing of the reception process 206a corresponds to the processing of the reception unit 151. The processing of the service selection process 206b corresponds to the processing of the service selection unit 152. The processing of the job selection process 206c corresponds to the processing of the job selection unit 153. The processing of the output process 206d corresponds to the processing of the output unit 154.

Note that each of the programs 207a to 207d does not necessarily have to be stored in the hard disk device 207 from the beginning. For example, each program may be stored in a "portable physical medium" such as a flexible disk (FD), CD-ROM, DVD, magneto-optical disk, or IC card that is inserted into the computer 200. Then, the computer 200 may read and execute each of the programs 207a to 207c.
