Clean, structured data speeds up development. Messy or sparse data means more time on preparation. Multiple data sources, real-time streaming, or unstructured formats (images, text, audio) add complexity.
A basic classification model costs less than a custom deep learning architecture. If you need 99%+ accuracy or the model must handle edge cases gracefully, expect more iteration and testing.
Connecting to a single API is straightforward. Integrating with legacy ERPs, multiple data warehouses, and real-time systems requires more engineering. Each integration adds scope.
If you need automated retraining, drift detection, model versioning, and governance workflows, the infrastructure investment is higher. Essential for production systems, optional for PoCs.
Healthcare, finance, and government projects come with HIPAA, SOC 2, or FedRAMP requirements. Compliance adds 15-25% to project costs but is non-negotiable in regulated industries.
Plan for 15-25% of initial build cost annually. Models need retraining as data drifts, integrations need updates when APIs change, and new requirements emerge as the business evolves.
