End-to-end prototype slices
One coherent workflow implemented deeply enough to expose real product behavior.
LABS / EXPERIMENT TYPE 03
Prototype Systems.
Make the concept tangible enough to interact with, break and understand.
We turn abstract systems into working prototypes that expose workflows, interfaces and technical relationships before the full product architecture is committed.
When diagrams are no longer enough.
A system prototype is useful when people need to interact with the idea, see the workflow and expose hidden complexity before a production build.
Start with
the uncertainty.
- A multi-step product concept is difficult to evaluate from screens alone.
- Stakeholders disagree because everyone imagines the workflow differently.
- Technical relationships need to be demonstrated before architecture is finalized.
- A service concept needs a working end-to-end slice.
- A new internal system needs real workflow feedback before development expands.
- An experimental interface needs to connect to enough real logic to feel credible.
Only enough
to find out.
Interactive system prototypes
Clickable or functional systems for testing navigation, state and workflow.
Data-backed prototypes
Experimental products connected to lightweight persistence where state matters to the test.
Operational prototypes
Simplified internal systems built around one real recurring process.
Service prototypes
Digital plus human workflow simulations for testing a broader service concept.
Technical demonstrators
Small systems showing how components, services or devices might work together.
Fragments into function.
The experiment
Fragments into function
Enough structure to use. Enough openness to change.
Fragments
Identify the pieces the question actually needs.
Incomplete sections align into a continuous passage. The prototype becomes useful when the parts connect—not when the surface looks finished.
A method,
not a guess.
- 01
MODEL
Map the minimum system behavior that needs to become tangible.
- 02
SELECT THE SLICE
Choose one end-to-end path that represents the hardest or most valuable part.
- 03
BUILD
Create only the interfaces, state and logic needed for the prototype to behave credibly.
- 04
BREAK
Push the prototype through edge cases and awkward workflow transitions.
- 05
LEARN
Record what became clearer once the system was real enough to interact with.
- 06
GRADUATE OR REWORK
Use the evidence to reshape the architecture or move toward production.
What we learn.
What we use.
Tools serve the question. They are not a fixed stack or a promise of an outcome.
Evidence to collect
- End-to-end slice
- Interaction findings
- System constraints
- Prototype data
- Architecture questions
- Graduation plan
Experiment materials
- TypeScript
- React
- Next.js
- Python
- PostgreSQL
- Docker
Stop↗
The evidence says the idea should stop here.
Iterate↗
The question became clearer, but another experiment is justified.
Graduate↗
The idea earned a path into a permanent Yard or product.
A prototype should reveal complexity before production has to absorb it.
Good questions
come first.
How is a prototype system different from an MVP?
A prototype is built to learn. An MVP is a production product intended to deliver value to real users.
Can prototypes use real data?
Sometimes, but test data or controlled data is often safer and sufficient depending on the question.
Can a prototype include authentication?
Yes, if identity or permissions are part of the uncertainty being tested.
Do you design the interface too?
Enough interface design can be included to make the workflow credible for the test.
Can the prototype code be reused?
Possibly, but reuse should be a conscious decision after reviewing what was intentionally simplified.
Can prototype systems become Software Yard projects?
Yes. Graduation into Software Yard is a natural next step when the experiment has earned a production roadmap.
