Where teams get it wrong
Building undifferentiated ERP, HRMS or CRM is almost always a mistake. Buying differentiated core product where the software is the moat is usually a mistake.
Comparison
Build vs Buy
The build vs buy decision is often made on ideology rather than analysis. Here is a framework that produces defensible decisions.

| Differentiation | Full control | Constrained to platform |
| Risk | Execution + maintenance | Vendor + fit |
| Fit | Exactly your process | 80% fit is typical |

Our honest verdict
Buy the commodity; build the differentiator. If a category has mature productized options and your process is not a competitive advantage, buy. Build only when the software itself is the moat.
