Voice of the Customer (VOC)

VOC is the captured understanding of customers stated wants and unstated expectations. Teams should grasp these needs before designing a product or service, with the Product Owner acting as the customers proxy to bring the VOC into decisions and priorities.

Key Points

  • Includes both explicit requests and implicit expectations from customers and users.
  • Should be identified early and refined continuously through feedback and learning.
  • The Product Owner represents the VOC and turns it into backlog items and acceptance criteria.
  • Common sources: interviews, surveys, observation, support tickets, and analytics; prioritize by customer value.

Example

In a Scrum project for a mobile app, the Product Owner interviews users and reviews support tickets to uncover that users want faster checkout (explicit) and fewer taps (implicit). The PO creates user stories with acceptance criteria for one-tap payments and reorders the backlog to deliver this first.

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.
