Net Promoter Score

A customer loyalty metric that gauges how likely people are to recommend a companys products or services to others, summarized into a single score from a simple survey question.

Key Points

  • Based on one survey question: 'How likely are you to recommend us?' rated from 0 to 10.
  • Responses are grouped as Detractors (0-6), Passives (7-8), and Promoters (9-10).
  • NPS = percent Promoters minus percent Detractors; the result ranges from -100 to +100.
  • Used to track customer sentiment and guide product or service improvements over time.

Example

After an agile release, the team surveys 200 customers. They receive 90 Promoters, 70 Passives, and 40 Detractors. NPS = (90/200*100) - (40/200*100) = 45 - 20 = 25. The team reviews Detractor feedback to prioritize fixes in the next sprint.

PMP Example Question

Which measure captures how likely customers are to recommend a product or service and is calculated as the percentage of Promoters minus the percentage of Detractors?

  1. Customer Satisfaction (CSAT)
  2. Net Promoter Score
  3. Earned Value
  4. Schedule Performance Index

Correct Answer: B — Net Promoter Score

Explanation: NPS specifically measures likelihood to recommend and is computed as percent Promoters minus percent Detractors, yielding a score from -100 to +100.

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.
