An engineering team has created a detailed CAD model and a full set of blueprints for a Typhoon-Proof Bahay Kubo. They have performed theoretical stress calculations, but no physical parts or scale models have been constructed.

A student mashes newly discovered color-changing berries and applies the paste to a piece of spoiled meat in a petri dish. They observe that the paste successfully changes color in the presence of spoilage. This is a basic experimental proof of concept.

A small-scale PVC pipe water filter is built and tested within a controlled laboratory setting. The team runs synthetically mixed muddy water through it to verify that the filtration mechanism functions as intended.

A cassava-peeling mechanism consisting of a blade and motor is bolted to a laboratory table. It is tested using dirty cassava roots, but the machine is still manually operated by an engineer rather than running automatically, and the environment is a shed (relevant environment) rather than a factory.

A prototype agricultural drone is flown outdoors at a designated flying field under calm weather conditions. The system is a functional prototype performing in an operational environment (outdoor flight), but not yet under harsh or mission-critical conditions.

A mobile app has been deployed to the Google Play Store and currently has 5,000 active daily users who are using it for its intended purpose in the real world.

A spoilage-indicator sticker has passed all FDA safety standards, and the final packaging has been approved for mass production. The system is considered "qualified" and ready for full commercial deployment.

A software team creates a UML Use-Case diagram and writes a project proposal for a Face-ID Attendance System. They have defined the application of the technology, but no code has been written.

A rough Arduino setup on a breadboard successfully blinks an LED when a specific sensor is triggered. This demonstrates that the core idea works electronically, but the components are not yet integrated into a cohesive module.

A solar inverter prototype is tested using a grid simulator that mimics complex brownouts and power surges. The validation happens in a high-fidelity simulated environment that closely matches reality.

A beta version of a mobile app is released on TestFlight. Twenty classmates download it and test it on their personal phones, identifying bugs and usability issues in a relevant environment.

A new factory layout is implemented in one small section of a real production line for one week to demonstrate its effectiveness in an operational environment before a full rollout.

A drone receives its official registration and safety certification from the Civil Aviation Authority of the Philippines (CAAP), confirming it meets all regulatory requirements for operation.

A student notices that pulverized oyster shells mixed with sand seem to create a hard binder when left in a beaker. This is a basic observation of a property, with no specific application or testing yet designed.

The Department of Public Works and Highways (DPWH) certifies that the oyster-shell concrete mixture meets all standards for rural road construction, qualifying the material for public use.

A fleet of agricultural drones has been operating daily for 6 months, serving real farms and successfully completing paid missions without significant failure.

A drone’s propulsion system (motor, ESC, and propeller) is mounted to a static test stand in a lab to measure thrust efficiency. The components are working together, but not on a flying vehicle.

A Face-ID system is wrapped in a simple web interface and works only on the developer’s high-performance laptop. The algorithm is validated in a controlled ("lab") device, not the target mobile hardware.

A drone frame is flight-tested inside a large gymnasium. The environment is relevant (it's flying), but the conditions are controlled (no wind/weather), serving as a high-fidelity prototype demonstration.

A mobile app is in the "Release Candidate" state. It is feature-locked, has passed all internal QA tests, and is being prepared for final submission to the App Store.

A 3D-printed shark-skin wing section is tested in a tabletop wind tunnel. This is a low-fidelity validation of the component in a laboratory setting.

An electric jeepney prototype is tested on a private test track. It carries no passengers, but it is a full system prototype running in a relevant (simulated road) environment.

A solar battery system is installed in a real house and successfully powers it for a full month completely off-grid. The system is "qualified" through this successful real-world operation.

A typhoon-proof bamboo community center effectively shelters residents during an actual super typhoon, proving its design in the ultimate operational mission.

An app is deployed to a cloud staging server (a relevant environment) and is tested using mobile data with 1,000 dummy users to simulate traffic load.

A sensor system is installed on an EDSA footbridge for 30 days. It is exposed to real environmental stress (heat, smog, vibration) to prove it can survive the operational environment.

A small sample cube of oyster-shell concrete is crushed in a universal testing machine in a lab to determine its compressive strength. This validates the component properties in a controlled setting.

A drone design is created using CAD software, including theoretical lift, battery life, and mass calculations. The technology application is formulated, but nothing is built.

Oyster-shell concrete is used to pave a barangay driveway and is exposed to real vehicles and daily usage for testing purposes (System prototype in operational environment).
