| Option / Approach | Best When | Primary Tradeoff / Risk | Recommended Fit |
|---|---|---|---|
| In-house hire | 12+ month roadmap with budget for recruiting and management | 3–6 month hiring cycle, high recruitment fees, and fixed long-term payroll overhead regardless of development volume. | Companies with dedicated HR pods |
| Offshore body shop | Well-defined tasks with internal tech lead and QA | High enterprise overhead markup, tiered account management layers, and slower communication turnarounds. | Large enterprise discretionary budgets |
| DIY no-code tools | Simple workflows under 500 monthly actions with no compliance needs | Scalability bottlenecks, vendor lock-in, architectural rigidity, and substantial technical debt before handling production traffic. | Early validation & UI experiments |
| GreeLogix Pod | Accountable production delivery with senior engineers, weekly demos, and fixed milestone velocity. | Requires active product owner for weekly sprint reviews and scope alignment. | Production & Scaling (Recommended) |
