Constraint

A restriction or condition that limits how a project, program, portfolio, or process can be carried out.

Key Points

  • Constraints cap or limit elements such as scope, schedule, cost, quality, resources, or risk.
  • They can be internal (policies, budget caps, resource limits) or external (laws, regulations, contracts, market deadlines).
  • Identify and document constraints early (e.g., in the charter) and refine them during planning and baseline development.
  • Changes to one constraint often affect others, requiring trade-offs and formal change control.

Example

A project must launch by June 30 due to a regulatory deadline and cannot exceed a $500,000 budget. The team reduces noncritical features and phases the rollout to meet the fixed date and cost limits.

PMP Example Question

A sponsor mandates that the product go live by June 30 and total spending must not exceed $500,000. What does this represent?

  1. Risk
  2. Assumption
  3. Constraint
  4. Dependency

Correct Answer: C — Constraint

Explanation: A fixed deadline and budget ceiling are limiting factors that restrict how the project can be executed, which defines a constraint.

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.
