Create WBS

The act of breaking project deliverables and the work required into smaller, controllable pieces so they can be estimated, scheduled, and managed.

Key Points

  • Produces a hierarchical Work Breakdown Structure focused on deliverables; the lowest level is a work package.
  • Uses decomposition and stops when work packages are clear enough to plan, estimate, and control.
  • Applies the 100% rule to capture the entire scope with no gaps or overlap.
  • Key outputs include the WBS, WBS dictionary, and updates to the scope baseline and related documents.

Example

A project to develop a mobile app is decomposed into deliverables such as Requirements, Design, Development, Testing, and Release. Each deliverable is further split (e.g., Development into Front-end, Back-end, and Integration), and then into work packages like "Implement login API" or "Build onboarding UI" that can be estimated and assigned.

PMP Example Question

Which activity best represents the Create WBS process?

  1. Breaking deliverables into hierarchical work packages to form the scope baseline.
  2. Sequencing activities to build the project schedule network diagram.
  3. Identifying stakeholders and documenting their expectations.
  4. Estimating durations for each defined activity.

Correct Answer: A — Decomposing deliverables into work packages

Explanation: Create WBS focuses on deliverable-oriented decomposition to produce the WBS and related components of the scope baseline, not on sequencing, stakeholder identification, or duration estimating.

ICS/OT Cybersecurity Fundamentals — Security Built for Industrial Systems

Industrial control systems cannot be secured like ordinary IT. A forced reboot, aggressive scan, or incompatible patch can interrupt production and create real safety consequences. Effective OT security begins with understanding the systems, constraints, and risks unique to industrial environments.

This course gives IT professionals, engineers, operators, and security practitioners a practical foundation in ICS threats, zone and conduit design, risk assessment, passive asset visibility, and vendor evaluation. You will learn how IEC 62443, NIST CSF, and MITRE ATT&CK for ICS apply where availability and safety come first.

Eight reconstructed incidents—including Stuxnet, Triton, Ukraine 2015, Colonial Pipeline, and PIPEDREAM—show how attackers move through OT environments, what they target, and which defenses could have changed the outcome.

Watch the course preview, then build the vocabulary, frameworks, and judgment needed to take credible first steps in ICS/OT cybersecurity.
