modeling

The practice of producing simplified representations of a system, solution, or deliverable (e.g., prototypes, diagrams, or storyboards) to explore, validate, and communicate ideas.

Key Points

  • Captures the essentials of a product or process without full detail.
  • Common forms include prototypes, diagrams, wireframes, and storyboards.
  • Supports early feedback, shared understanding, and assumption validation.
  • Iterative and refined as new learning and stakeholder input emerge.

Example

On an agile mobile app project, the team builds low-fidelity wireframes and a clickable prototype to review user journeys with stakeholders in Sprint 1, then updates the models based on feedback before starting development.

PMP Example Question

A team wants to align stakeholders and test user flows before coding. Which technique should they apply?

  1. Earned value analysis
  2. Modeling
  3. Variance analysis
  4. Monte Carlo simulation

Correct Answer: B — Modeling

Explanation: Modeling uses simplified artifacts such as prototypes, diagrams, or storyboards to visualize and validate the solution before development.

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.

Build an ICS/OT cybersecurity foundation that fits the real environment

Standard IT controls can disrupt the industrial systems they are meant to protect. Learn how to assess OT risk, design zones and conduits, apply IEC 62443 security levels, use MITRE ATT&CK for ICS, and establish passive asset visibility without risking production. Eight reconstructed incidents connect attacker techniques to the controls that failed, giving you the vocabulary and judgment to make credible security decisions from day one.
