Common SME Pitfalls and How to Avoid Them

Pitfall 1: Over-Engineering Too Early

Problem: Implementing enterprise-grade solutions before reaching necessary scale. Solution: Start with native tools, upgrade when ROI justifies the complexity.

Pitfall 2: Ignoring Team Productivity Impact

Problem: Cost optimization efforts that reduce team velocity. Solution: Balance cost savings with developer experience and productivity metrics.

Pitfall 3: Single-Cloud Lock-In

Problem: Missing cost arbitrage opportunities due to vendor commitment. Solution: Maintain multi-cloud optionality for cost-sensitive workloads.

Pitfall 4: Neglecting Governance

Problem: Individual teams optimizing in silos without coordination. Solution: Light-weight governance with clear ownership and processes.

Pitfall 5: Short-Term Thinking

Problem: Optimizing for monthly costs instead of long-term business value. Solution: Align cost optimization with business strategy and growth plans.
