Reporting & AI Insights

How SPECTRA generates analytical reports with LLM-assisted summaries and analyst approval.

The Report Workflow

SPECTRA’s reporting module bridges the gap between statistical analysis and regulatory-ready documentation. The workflow has three stages:

1. Select Graphs for the Report

As you work through the analysis modules (batch profiling, process charts, PCA, PLS, capability analysis), each chart has a “Add to Report” action. Selected graphs are queued with their derived statistics — control limits, violation counts, PCA loadings, and capability indices.

2. AI-Generated Insights

For each selected graph, SPECTRA feeds the derived statistics into an LLM that generates a plain-language analytical summary. For example, a process parameter analysis chart might produce:

“The parameter pH showed 4 violations across 12 batches analyzed at ±3σ, affecting 2 unique batches (16.7% violation rate). All violations were UCL breaches classified as major. Batch B-0042 had the worst deviation at +4.2σ above centerline.”

The analyst then reviews each AI-generated summary and can:

  • Accept — the text is marked as “Verified by Analyst” in the final report
  • Reject — the text is excluded or shown as unverified
  • Add notes — free-text field for the analyst’s own interpretation

This workflow ensures AI assists but never replaces human judgment.

3. Export to Word (.docx)

The final report is generated as a Word document containing:

  • Cover page — project name, date, analyst name
  • Table of contents — auto-generated Word field codes that update when opened
  • Per-insight sections — each with the chart image, derived statistics, analyst notes, and AI summary (if approved)
  • Page numbers — “Page X of Y” in the footer

The document uses Word-native heading styles, so the table of contents resolves automatically in Microsoft Word or Google Docs.

Why Not Just PDF?

Word and PDF outputs match standard GMP documentation formats, so teams use them directly for review, approval, and archiving. Word supports collaboration and editing, while PDF provides a fixed, audit-ready version. This removes manual reformatting and speeds up validation and inspection workflows.

Data in the Report

The report includes only the statistics and parameters you selected — no raw data is dumped into the document. Each insight section records:

  • Module slug and page label (e.g. “PPA — Process Parameter Analysis”)
  • Graph title and summary text
  • All derived stats (sigma multiplier, UCL/LCL values, violation counts, severity breakdown)
  • Dropdown states and filter selections at the time of capture
  • Analyst notes and AI text with approval status
