Resource Breakdown Structure (RBS)

Correct Answer: To organize and categorize project resources in a hierarchical structure

A Resource Breakdown Structure (RBS) serves as a hierarchical representation of resources by category and type. Its primary purpose is to provide a structured way to organize and categorize all project resources. The correct answer reflects this fundamental purpose, as the RBS is indeed a hierarchical decomposition of resources arranged by resource categories and types, helping project managers effectively plan and manage resources. The other options describe different project management tools and concepts: - Establishing dependencies and critical path is related to network diagrams and Critical Path Method (CPM), not RBS - Calculating costs and budget variances is primarily done through cost management tools and techniques - Tracking performance metrics and productivity is handled through performance management systems and earned value management The RBS's main function is organizational - providing a clear structure for resource categorization, which supports resource planning, allocation, and management throughout the project lifecycle.

Correct Answer: To categorize and organize resources based on their skills, competencies, and organizational structure

The Resource Breakdown Structure (RBS) is primarily a hierarchical representation of resources organized by category and type. The correct answer focuses on the main purpose of RBS: categorizing and organizing resources based on their skills, competencies, and organizational structure. This hierarchical decomposition helps project managers understand their resource pool and make informed decisions about resource allocation. The other options describe different aspects of resource management but not the primary purpose of RBS: - Creating timelines for resource entry/exit is part of resource scheduling, not RBS - Listing resources with costs is more related to cost management and resource budgeting - Analyzing dependencies and allocation scenarios is part of resource leveling and optimization RBS serves as a foundation for understanding the organization's resource capabilities and structure, making it easier to identify required skills, plan capacity, and manage resource allocation effectively.

Correct Answer: RBS categorizes resources based on their functions, while functional departments manage operational responsibilities

The correct answer is that RBS categorizes resources based on their functions, while functional departments manage operational responsibilities. Here's why: An RBS (Resource Breakdown Structure) is a hierarchical categorization of resources by type and function. It helps in organizing and identifying resources needed for project activities. Meanwhile, functional departments are permanent organizational units responsible for ongoing operational activities and management. The other options are incorrect because: RBS is not limited to temporary project resources - it includes all types of resources available to the organization. RBS does not manage resource allocation - it is a categorization tool, not a management system. Resource allocation is handled through resource management processes. RBS does not determine hierarchical authority - it is a categorization structure, not an organizational authority chart. Organizational authority is defined by the organizational structure and governance frameworks.
