SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

QA analysis before sharing with stakeholders — methodology checks, accuracy verification, and bias detection. Use when reviewing an analysis for errors, checking for survivorship bias, validating aggregation logic, or preparing documentation for reproducibility.

Core Features & Use Cases

  • Pre-delivery QA checklist for data analyses, dashboards, and reports
  • Detection of survivorship bias and other methodological pitfalls
  • Validation of aggregation logic and calculation accuracy
  • Documentation templates to support reproducibility and transparency
  • Guidance for communicating findings to stakeholders

Quick Start

Provide your analysis report and data appendix to run the pre-delivery QA checklist and generate a reproducibility-ready review.

FAQPage Schema
How do I run a QA checklist on a data analysis before sharing it with stakeholders?

To run a pre-delivery QA checklist on a data analysis, provide your report and data appendix to verify methodology, calculation accuracy, and bias before sharing with stakeholders. The review identifies errors and generates reproducibility documentation.

What is survivorship bias and how do I detect it in a data analysis report?

Survivorship bias in a data analysis report is a methodological pitfall where only successful subjects are visible. You detect it by applying structured bias checks during pre-delivery QA to identify overlooked missing data segments.

How do I validate aggregation logic and calculation accuracy in BI dashboards?

To validate aggregation logic and calculation accuracy in BI dashboards, apply a structured pre-delivery QA checklist to verify calculations and identify miscalculations. This ensures metrics are accurate before stakeholder distribution.

Does this data validation process work for research analytics and BI reports?

Yes, this data validation process works for research analytics and BI reports. It applies a structured pre-delivery QA checklist across research, BI, and analytics contexts to check methodology, detect biases, and validate aggregations.

What is the best way to document data analysis reproducibility before delivery?

The best way to document data analysis reproducibility is using structured documentation templates during pre-delivery QA. These templates capture methodology checks and validation steps to support transparency and reproducible analyses.
