Conflict Resolution - how you handled project conflicts with teammates

Situation: A teammate insisted on full refresh for a large fact table; I advocated incremental loads for cost and speed. The disagreement escalated and risked project timelines. Task: Resolve the technical conflict without damaging the relationship. Action: I scheduled a 1:1, shared benchmarks (incremental 5x faster, ~80% cost savings, same correctness under our SCD2 contract). I proposed a pilot on one table and offered to own implementation and validation. We ran both approaches; results clearly favored incremental. I framed the outcome around team goals, not personal preference. Result: We adopted incremental across the pipeline. Relationship improved. I later mentored the teammate on incremental design patterns. Lesson: Use data to resolve technical conflicts; propose experiments; focus on outcomes, not ego. Respect and evidence lead to alignment.
