Rework

Corrective work performed to fix a product or component that fails quality checks, bringing it into alignment with the defined requirements and standards.

Key Points

  • Triggered when an output is found defective or not meeting stated criteria during inspections or testing.
  • Consumes time and budget; if baselines are impacted, it may require a formal change request and approval.
  • It is corrective (fixing issues found), not preventive (avoiding issues before they occur).
  • Reduced by solid quality planning, clear specifications, early reviews, and effective quality control.

Example

During quality control on a construction project, a concrete section is discovered to be out of tolerance. The crew removes the nonconforming portion and repours it so the final work meets the project specifications. This corrective effort is rework.

PMP Example Question

During inspection, a component is found outside the required tolerance. The team machines the part further so it meets the stated requirements. What is this activity called?

  1. Preventive action
  2. Rework
  3. Validate Scope
  4. Gold plating

Correct Answer: B - Rework

Explanation: The team is correcting a nonconforming item so it satisfies defined requirements, which is rework.

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.
