解説
問 31
- ア
正解 Gap analysis places the current state (As-Is) and the desired state (To-Be) side by side, compares them, and identifies the difference (gap) between them as issues to be resolved. In EA (Enterprise Architecture), you first grasp the existing systems and business structure, then draw the ideal model, and build the migration plan from that gap. The question's description — comparing the current state with the desired state to clarify issues — is itself the definition of gap analysis, so the correct answer is ア.
Incorrectイ
Core competence analysis identifies a company's core strengths (core competences) that competitors cannot easily imitate; it is not a technique for clarifying the difference between the current state and the desired state.
Incorrectウ
Value chain analysis divides business activities into primary activities and support activities and analyzes where each step creates value; it does not identify issues by comparing the current state with the ideal state.
Incorrectエ
Pareto analysis arranges items in descending order and looks at their cumulative ratio (the so-called 80-20 rule) to find the vital few that should be managed with priority. It is not an analysis that compares the current state with the desired state.
ここがポイント
- Gap analysis = a technique that compares the current state (As-Is) with the desired state (To-Be) and clarifies the difference (gap) as issues. It is the basis for building a migration plan in EA.
- Distinguish the easily confused management analysis terms: core competence analysis (a company's core strengths), value chain analysis (the chain of value-creating activities), and Pareto analysis (extracting the vital few) each have a different purpose.
