Project Stages:
| Stage | Stage Name | What Happens in This Phase? | Outcome / Deliverable |
| 1 | Idea / Concept | Initial idea creation, defining the vision and purpose of the project. | Clear project concept and direction.Project vision document, initial feature list (e.g., ”Retro arcade machine with moveable controller consoles”). |
| 2 | Requirements | Gather all desired features, goals, user needs, constraints, and expectations. | Complete list of requirements and objectives. |
| 3 | Main Components | Break the project into major systems, modules, or functional areas. | Defined main components (e.g. control system, cooling, catering, mechanics, safety). |
| 4 | Technical Specification | Detailed technical definition of each component: dimensions, materials, tolerances, standards, performance requirements. | Full technical specifications for all components. |
| 5 | Product Engineering | Actual engineering and design work: CAD models, structural solutions, technical trade-offs, integration planning. | Finalized engineering solutions, 3D models, technical drawings. |
| 6 | Prototyping | Build and test first prototypes or proof-of-concept versions. | Working prototypes and test feedback. |
| 7 | Manufacturing Documents | Prepare production files, assembly instructions, BOM lists, CNC files, supplier packages. | Ready-to-manufacture documentation package. |
| 8 | Building / Production | Physical construction, assembly, or event implementation begins. | Product or project physically built. |
| 9 | Testing / QA | Functional testing, stress testing, quality control, performance validation. | Test reports, issue list, verified quality level. |
| 10 | Finishing / Corrections | Final improvements, refinements, bug fixes, cosmetic finishing. | Polished near-final result. |
| 11 | Final Review / Approval | Final inspection, sign-off, approval. | Officially approved final product/project. |
| 12 | Launch / Completion | Delivery, handover, release, public opening, or project closeout. | Completed and launched project. |
