Creating a Certificate of Analysis (COA)

A Certificate of Analysis (COA) is an important component of manufacturing processes and continuous improvement efforts. It provides documented evidence that product results meet defined specifications and allows organizations to communicate quality results to customers with confidence.

Quality Window supports the collection, validation, and reporting of manufacturing data, making it well-suited for generating COAs directly from production results.

COAs are generated using validated data, ensuring that results reflect actual production conditions and meet customer expectations. This eliminates the need for manual data handling and helps maintain consistency across batches and reports.

Get Started Creating Your Certificate of Analysis

COAs in Quality Window are generated by selecting the appropriate dataset and applying a report or document template to produce a customer-ready output.

This process allows you to:

  • Control which data is included (batch, lot, time range, or filtered dataset)
  • Ensure results align with defined specifications
  • Generate consistent, repeatable COA documents

For a step-by-step guide on generating COAs, see:

Controlling COA Data and Output

COAs are built from selected datasets, allowing users to define exactly what information is included in each document.

This includes:

  • Selecting specific batches or production runs
  • Filtering records based on process or inspection criteria
  • Ensuring only relevant and approved data is included

This level of control ensures that each COA accurately represents the intended scope of production data.

Consistent and Scalable COA Generation

Quality Window enables COA generation as a repeatable process, reducing the need for manual preparation.

Using templates and structured data:

  • COAs can be generated consistently across products and customers
  • Formatting remains standardized
  • Data is pulled directly from the source without re-entry

This approach supports operations where COA generation must scale with production while maintaining accuracy and consistency.

Advanced COA Design and Customization

For more complex or highly specific COA requirements, Quality Window also supports advanced document generation approaches using scripting and external tools such as Microsoft Word or Excel.

These approaches are typically used when:

  • COA layouts require highly specific formatting
  • Additional calculations or conditional logic are needed
  • Unique customer or regulatory requirements must be met

This provides flexibility beyond standard COA generation, allowing organizations to support both standardized and highly customized reporting workflows.

Beyond Certificates of Analysis

Creating COAs is one part of a broader quality and process monitoring workflow. Quality Window is also used for:

  • Process monitoring and control
  • Data collection and validation
  • Statistical analysis and reporting
