Business Requirements Document (BRD)

A formal, structured record that specifies and details an organization’s business needs.

Key Points

  • Defines what the business needs and why, not how the solution will be built.
  • Includes objectives, scope, stakeholders, high-level processes, and acceptance criteria.
  • Serves as a baseline for scope management and change control.
  • Requires review and approval from key business stakeholders to ensure alignment.

Example

A bank plans to launch mobile check deposit. The BRD outlines the business goal (increase digital adoption by 20%), in-scope features (capture, review, submit), excluded items (foreign checks), stakeholders (retail banking, compliance), constraints (regulatory hold times), and acceptance criteria (99.5% successful deposit submissions).

PMP Example Question

Which document primarily captures the organization’s detailed business needs and expected outcomes to guide solution selection?

  1. Business Requirements Document (BRD)
  2. Software Requirements Specification (SRS)
  3. Project Charter
  4. Product Backlog

Correct Answer: A — Business Requirements Document (BRD)

Explanation: The BRD documents the business needs and desired outcomes. The SRS details system requirements, the charter authorizes the project at a high level, and the product backlog orders solution work items.

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.
