Quality Function Deployment (QFD)

A structured approach that converts the voice of the customer into clear, measurable engineering and design specifications.

Key Points

  • Captures and prioritizes customer needs (voice of the customer) before design work begins.
  • Uses the House of Quality to map customer needs to technical characteristics and target metrics.
  • Supports trade-off analysis and prioritization so engineering effort aligns with what customers value most.
  • Creates traceability from needs to design, verification, and test criteria through cross-functional collaboration.

Example

An agile team building a wearable fitness tracker gathers customer needs such as "battery lasts a week," "accurate heart rate," and "swim-proof." They use QFD to translate these needs into technical specs: minimum 7-day battery life, heart-rate error under 5%, and water resistance to 50 meters. These specs inform backlog items and acceptance criteria, guiding design choices and trade-offs (e.g., display brightness vs. battery capacity).

PMP Example Question

An agile team wants a technique that links prioritized customer outcomes to specific system parameters and target metrics, enabling trade-off decisions during design. Which method should they use?

  1. Kano analysis
  2. Quality Function Deployment (QFD)
  3. MoSCoW prioritization
  4. Value stream mapping

Correct Answer: B — Quality Function Deployment

Explanation: QFD translates customer needs into technical characteristics and targets (often via the House of Quality), supporting objective trade-offs. The other options prioritize or analyze value/flow but do not map needs to engineering specs.

ICS/OT Incident Response Drills and Exercises

An incident response plan is only a theory until the people who must use it have run it under pressure. This course helps OT engineers, operations leaders, IT responders, and security teams turn a plan on paper into a tested capability.

Define safe states and manual fallback before an incident forces the decision. Build escalation paths, tabletop exercises, and scenarios that expose the gaps a document review cannot find.

Then turn the results into evidence: an after-action report, owned improvements, recovery checks, and a drill cadence that keeps the program alive after the exercise ends.
