Reproducibility starts with environment control. I prefer containerized workflows where every tool and dependency is versioned, and where parameters are logged alongside outputs.

The second pillar is modularity. Pipelines should be composed of small, testable steps that can be independently validated. This makes it easier to track failures, compare results, and update components without breaking the entire workflow.

Finally, documentation should be treated as part of the pipeline. Clear inputs, outputs, and expected artifacts allow collaborators to understand the intent of the analysis and trust the conclusions.
