解説
問 54
Incorrectア
CRM (Customer Relationship Management) is a method for continuously managing and analyzing relationships with customers to improve satisfaction and increase sales. It has nothing to do with the hierarchical breakdown of project work.
Incorrectイ
ERP (Enterprise Resource Planning) is a concept and system that integrally manages management resources such as people, goods, money, and information to make operations more efficient. It is not a method for breaking down project work.
Incorrectウ
PPM (Project/Product Portfolio Management) is a method that takes an overall-optimization view across multiple projects or product groups to decide investment allocation and priorities. It does not identify and hierarchically organize the work within a single project.
- エ
正解 The WBS (Work Breakdown Structure) in エ is a method that breaks all the work to be carried out in a project down step by step—from large deliverables and processes into small work units—and organizes it into a tree-shaped hierarchical structure. The lowest-level elements are called “work packages,” and they become the smallest management unit for estimating effort, scheduling, cost, and progress tracking. Because it meets all the conditions in the question—“identify all the work and organize it into a hierarchical structure” and “clarify the management units”—エ is correct.
ここがポイント
- WBS is a representative method of the planning phase that breaks all project work down into a hierarchical (tree) structure and uses the lowest-level work packages as the unit for estimation and progress tracking.
- Distinguish that the three incorrect options are abbreviations for entirely different domains: CRM = customer relationship management, ERP = integrated management of enterprise resources, and PPM = overarching management of multiple projects/products.
