Why We're Testing Process Design Criteria (PDC) at Singularity

What if you could trace every number in your engineering work back to the exact page and document it came from? At Singularity, we're exploring a simple but powerful idea: standardizing how we log inputs before we calculate anything.

What is the Process Design Criteria (PDC)? The PDC is a structured table that captures every input variable we use in our calculations. Each entry follows the same format:

Variable Description. Variable. = Value. Units. (Reference)

The reference tells us exactly where the information came from—including the document name, revision, and page or table number.

We wanted a better way to:

• Reuse values across different calculations

• Track sources without digging through PDFs

• Catch missing or inconsistent data before it causes problems

The PDC is helping us do that. It creates a clear path from source to result.

What's Good About It

• Traceability: We always know where each number came from

• Consistency: Everyone follows the same structure

• Speed: It makes it easier to create templates and prompts later

The PDC only works if every field is filled in. If a unit or reference is missing, it can break the flow. And yes—filling it out takes time.

But we think it's worth it.

When a client sends a process document, we enter all the key data into the PDC first. Then, we feed that table into ChatGPT to generate engineering calculations or data sheets.

It’s early days, but it’s already making our work easier to check and share.

We’re not calling this a solution—yet. But it feels like a step forward. The more we test it, the more we see how a simple table can bring clarity to complex engineering work.
