解説
問 48
Incorrectア
Software acceptance is the work in which the acquirer (the ordering party) confirms through acceptance testing and the like whether the installed software runs in accordance with the requirements and the contract, then inspects the deliverables and formally takes them over. Its purpose is confirmation and formal acceptance, not the installation work itself of performing the initial setup or preparing the execution environment. It is also a process positioned "after" installation, and on that point too it does not match the question.
Incorrectイ
Software integration is the development process in which modules and programs that have finished unit testing are combined, and integration testing confirms whether the interfaces between the modules function correctly. It is work done during development, not the work of preparing the production execution environment in accordance with the contract.
- ウ
正解 The correct answer is ウ "Software installation". Software installation refers to the work of putting software whose development (or package purchase) has been completed in place in the environment where it will actually be used, performing the initial setup of the software and databases (parameter settings, registration of initial data, and so on) exactly as specified in the contract or the installation plan, and thereby preparing an execution environment in which users can start operation as it is. The description in the question, "performing the initial setup as specified in the contract and preparing the execution environment", is this installation and setup work itself; it is neither a development process (integration), nor an inspection and acceptance process (acceptance), nor the handling of changes after operation has begun (maintenance). Therefore ウ is correct.
Incorrectエ
Software maintenance is the work of correcting defects found after operation has started, responding to revisions of laws and to changes in business operations, improving performance, and so on, thereby keeping the software in a state where it can continue to be used. It is an activity after the start of operation, and it does not correspond to the description in the question, which refers to the initial setup and environment preparation before the software goes live.
ここがポイント
- Software installation (setting in place) = the work of performing the initial setup of software and databases in accordance with the contract or the installation plan and preparing an execution environment in which users can start operation. Whenever the words "initial setup", "preparing the environment", or "setting in place (installing)" appear, judge it to be installation.
- The broad order of the software life cycle (a sequence with details such as qualification testing omitted) is: implementation (unit) → software integration → software installation → software acceptance → operation → software maintenance. If you locate which stage each choice's task belongs to, even confusingly similar terms can be told apart.
