Does anyone systematically track whether management actually delivers on previous earnings-call promises?

When researching a company, I find it relatively easy to access the latest earnings call, 10-Q and investor presentation.

What I find much harder is reconstructing what management said six, twelve or eighteen months ago and determining whether it actually happened.

For example:

\- Management promises a product launch by Q3.

\- The following quarter, it says the launch is progressing as expected.

\- Later, the deadline quietly disappears from the presentation.

\- The filing changes from a specific launch date to vague language about “evaluating timing.”

\- Nobody formally says the original target was missed.

The same thing happens with margin targets, factory openings, customer growth, profitability timelines, cost reductions and capacity expansion.

I am considering manually building a management-commitment ledger that records:

\- The exact original statement

\- Date and source

\- Measurable target or deadline

\- Later updates

\- Final outcome: delivered, delayed, revised, missed or unresolved

\- Any relevant changes in subsequent filings

I am not talking about another earnings-call summarizer or generic management credibility score. Every conclusion would link to the original and later evidence.

For those who regularly research individual companies:

How do you currently track this?

Do you maintain spreadsheets or notes, rely on memory, search old transcripts when needed, or use an existing platform?

What part of this process is most frustrating?

And what would make such a record genuinely useful rather than merely interesting?
