1. Feasibility Demonstration

When to use: Appropriate for showing the practicality and viability of a proposed idea or method.
Example: “The engineering team presented a feasibility demonstration of the new water filtration system.”

2. Prototype

When to use: Suitable for an original model or preliminary version of a product to test and refine the concept.
Example: “The design department developed a prototype of the new smartphone for internal testing.”

3. Pilot Project

When to use: Ideal for a small-scale preliminary study or experiment to evaluate the feasibility of a larger project.
Example: “The company launched a pilot project to test the new software in a real-world environment.”

4. Test Case

When to use: Used for an instance or scenario used to test a theory or concept’s validity.
Example: “They used the urban development project as a test case for the new environmental policies.”

5. Trial Run

When to use: Appropriate for a preliminary test of processes, methods, or products before full-scale implementation or production.
Example: “A trial run of the online ordering system was conducted to identify potential issues.”

6. Working Model

When to use: Suitable for a functioning model of a product or system that demonstrates how it will work.
Example: “The team built a working model of the app to showcase its features to investors.”

7. Concept Validation

When to use: Ideal for the process of proving that a concept or idea is viable and has potential for real-world application.
Example: “The research phase included concept validation of the new renewable energy technology.”

8. Proof of Principle

When to use: Used for demonstrating the fundamental feasibility of a concept or theory.
Example: “The experiment served as a proof of principle for the new drug’s effectiveness.”

9. Initial Prototype

When to use: Appropriate for the first or early model created to test and develop a concept.
Example: “The initial prototype of the drone was tested for basic functionality.”

10. Demonstrator

When to use: Suitable for a model or example that shows how a technology or concept operates.
Example: “At the trade show, they presented a demonstrator of the smart home system.”

11. Experimental Model

When to use: Ideal for a version of a product or system used specifically for experimentation and testing.
Example: “The laboratory developed an experimental model to study the new chemical process.”

12. Concept Trial

When to use: Used for testing a concept to understand its effectiveness or practicality.
Example: “The concept trial for the online platform revealed valuable user feedback.”

13. Alpha Version

When to use: Appropriate for an early version of a software product that is used for internal testing.
Example: “The software development team released the alpha version for bug testing.”

14. Proof of Functionality

When to use: Suitable for demonstrating that a particular function or feature of a product works as intended.
Example: “They created a small-scale application as a proof of functionality for the new algorithm.”

15. Preliminary Model

When to use: Ideal for an early version of a product or system that precedes the final or more complete version.
Example: “The preliminary model of the urban planning software was used to gather initial user feedback.”
