Product Backlog

A prioritized queue of user-focused needs that the team owns and continually updates for the product.

Key Points

  • Single, authoritative source of upcoming product work.
  • Ordered by value, risk, and dependencies so the most important items appear first.
  • Continuously refined as feedback emerges; items gain detail, estimates, and acceptance criteria as they rise.
  • Product owner manages content and ordering; the delivery team collaborates to refine and estimate.

Example

A mobile banking team maintains a product backlog with items such as "As a customer, I want to deposit checks by photo so I can avoid visiting a branch." The product owner orders these items by value and risk. High-priority items near the top have clear acceptance criteria and estimates, making them ready for the next sprint.

PMP Example Question

A team wants a single, prioritized source of all user-centered requirements for a product that is updated continuously as feedback arrives. Which artifact should they use?

  1. Sprint backlog
  2. Product backlog
  3. Project management plan
  4. Release burndown chart

Correct Answer: B — Product backlog

Explanation: The product backlog is the prioritized, evolving list of user-focused work maintained for the product; the other options serve different purposes.

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.
