解説
問 48
Incorrectア
Waterfall development is a development process model in which stages such as requirements definition, design, programming, and testing proceed in order from upstream to downstream; it has nothing to do with the perspective of where development is outsourced (domestic or overseas). It is not a term that describes a style of seeking cheap labor overseas, so it is incorrect.
- イ
正解 Offshore development refers to a development style in which all or part of system development is outsourced to overseas companies or overseas subsidiaries where labor costs are low. The explanation in the question, namely outsourcing development overseas with the aim of obtaining a large amount of cheap labor, matches the definition of offshore development itself, so the correct answer is イ. A typical example is Japanese companies outsourcing programming and testing work to countries with low labor costs (such as China, India, and Vietnam), where cost reduction is the main purpose.
Incorrectウ
Prototype development is a development method in which a trial product (prototype) is created at an early stage and the specifications are finalized while obtaining confirmation from users; its purpose is to clarify requirements. It differs from a style of outsourcing development overseas to obtain cheap labor, so it is incorrect.
Incorrectエ
Rapid Application Development (RAD) is a development method that uses development support tools and small teams to build a system in a short period, emphasizing development speed. It is not a term that refers to a style aiming at reducing labor costs through overseas outsourcing, so it is incorrect.
ここがポイント
- Offshore development = a development style in which system development is outsourced to overseas companies or subsidiaries with low labor costs. The main purpose is cost (labor cost) reduction.
- Waterfall, prototype, and RAD are terms that describe how development is carried out (process models/methods); distinguish them from offshore development, which describes an outsourcing style based on whether the outsourcing destination is overseas or domestic. The perspectives differ.
