Budget at Completion (BAC)

The total planned cost for completing the entire project, calculated by adding up all approved budgets for the work to be done.

Key Points

  • BAC is the project's total approved budgeted amount at completion (the cost baseline total).
  • In earned value management, BAC is used to calculate variance at completion: VAC = BAC - EAC.
  • BAC typically equals the total planned value (PV) at the project's finish and usually excludes management reserve.
  • BAC changes only through approved updates to the cost baseline via change control.

Example

A project has budgets of $250,000 for design, $150,000 for build, and $100,000 for testing. The BAC is $500,000, the sum of all those planned budgets.

PMP Example Question

Which earned value term is defined as "The sum of all budgets established for the work to be performed."?

  1. Actual Cost (AC)
  2. Budget at Completion (BAC)
  3. Estimate at Completion (EAC)
  4. Planned Value (PV)

Correct Answer: B — Budget at Completion (BAC)

Explanation: BAC represents the total approved budget for all planned work, i.e., the aggregated project budget at completion.

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.
