解説
問 37
- ア
正解 The correct answer is ア, SLCP. SLCP (Software Life Cycle Process) defines and standardizes, one by one, the work items needed across the whole life of software — planning, requirements definition, development, operation, maintenance, and disposal — arranging them in the layers of process, activity, and task. In Japan a version of it made concrete to fit domestic business practice, called the Common Frame, has been established. Because the acquirer who orders the software and the supplier who takes the order can confirm which work is done, by which side, and to what extent, using the same wording and the same categories, it prevents the mismatched understandings and troubles that arise from unclear work scope and responsibility, and it helps make transactions proper. SLCP is the only option that matches the question's wording about the proper conduct of transactions and about defining and standardizing the basic work items one by one.
Incorrectイ
WBS (Work Breakdown Structure) is a project management technique that breaks the deliverables and the work of a single project down hierarchically into pieces small enough to manage. What the breakdown contains is produced individually for each project; it is not a definition and standardization of work items shared across the industry, nor is its purpose to make software transactions proper.
Incorrectウ
Object-oriented is a way of thinking in which a system is analyzed, designed, and implemented in units of objects that unite data with the procedures that handle it, and it is characterized by encapsulation, inheritance, and polymorphism. It is a development technique that presents a philosophy of how to build software, not a framework that defines and standardizes the work items of the entire life cycle.
Incorrectエ
The data-centered approach (DOA) is a development method that focuses on the structure of the data handled in the business, settling the data model first and then designing the system from it. This too is one way of designing and developing a system, not something that identified work items and standardized them in order to make transactions between the party that orders and the party that supplies proper.
ここがポイント
- SLCP (Software Life Cycle Process) is a framework that defines and standardizes the work items from planning through requirements definition, development, operation, maintenance, and disposal in the layers of process, activity, and task, and its Japanese version is the Common Frame. Its purpose is to let the acquirer who orders and the supplier who takes the order confirm work scope and responsibility by a shared yardstick, and thereby to make software development and its transactions proper.
- Learn how to tell the confusable terms apart. SLCP is an industry-wide standard of work items, a common language for transactions; WBS is a chart that breaks the work of a single project down into a hierarchy; object-oriented and the data-centered approach are techniques for analyzing and designing a system. When the proper conduct of transactions and standardization appear in a question, choose SLCP.
