問 26
- ア
正解 The correct answer is choice ア, ASP (Application Service Provider). ASP stands for Application Service Provider. It refers to a service in which business application software runs on the provider’s own servers and is rented out to many users over a network such as the internet, and it also refers to the company that offers such a service. The description in the question — a service that makes business application software available for use over the internet — matches the definition of ASP exactly. From the user’s point of view, the advantage is that they do not have to buy a software package and install it on their own company’s servers, nor do they have to handle the later operation, maintenance, and version upgrades themselves; by paying a usage fee, for example a monthly one, they can use just the functions they need for just as long as they need them. SaaS (Software as a Service), which also appears in the glossary, is based on the same idea as ASP — providing software as a service over a network — but reorganized and renamed as one form of cloud service, so learning it together with ASP as a pair makes both easier to understand.
Incorrectイ
ERP (Enterprise Resource Planning) refers to the idea of managing a company’s business resources — people, goods, money, and information — in an integrated way across the whole organization in order to make management more efficient, and also to the integrated core business system that realizes this idea (an ERP package). This is a classification by what kind of business the system manages, not the name of a delivery form describing how software is delivered to users. An ERP package may indeed be offered in the form of ASP or SaaS, but even then it is ASP/SaaS that expresses the delivery form; the word ERP itself does not mean use over the internet, so this choice is wrong.
Incorrectウ
ISP (Internet Service Provider) is a connection provider that supplies the line connection, user accounts, e-mail addresses, and so on that let a user’s equipment connect to the internet. What it provides is the communication entrance of internet access, not business application software itself. The name looks similar to ASP and is easy to confuse, but you can avoid mixing them up by remembering that the A stands for a provider of applications (software) while the I stands for a provider of the internet (connection). The question asks for a service that makes business application software usable, so this choice is wrong.
Incorrectエ
SFA (Sales Force Automation), a sales support system, refers to a mechanism that shares and analyzes information about sales activities — such as customer information and the progress of negotiations and deals — within an organization, thereby helping the sales department raise its productivity. Like ERP, it is a classification by the purpose of a business system, not a word expressing a delivery form. SFA can certainly be used as a service provided over the internet, but that is because its delivery form is ASP or SaaS; the word SFA itself does not mean a service that is made available for use over the internet, so this choice is wrong.
- ASP means a delivery form, and a provider, that runs business application software on the provider’s servers and rents it out as a service over a network such as the internet. Its characteristic is that instead of buying software and installing it in your own company, you pay a usage fee to use the functions you need; learn it together with SaaS, which expresses the same idea within the framework of cloud computing.
- For multiple-choice questions about alphabetic abbreviations, it is easier to answer if you sort each term into either a word that names a delivery form or provider, or a word that names a type of business system or management method. ASP is a provider of software and ISP is a provider of internet access, while ERP (an integrated core business system) and SFA (a sales support system) are classifications by the content of the business.
