Report

A report is a document that summarizes figures and observations on a topic in an organized way. It is not meant to entertain, but to answer a question: How much was sold? How often did a program crash? How much electricity did a data center consume? Unlike a plain list of raw data, a report involves a selection, an ordering, and often a brief assessment. The English word has become established in German because it also implies regular recurrence. A report is typically produced daily, monthly, or quarterly according to the same pattern.

Why companies would be blind without reports

In a large company, no one can observe everything themselves. Reports are the way information travels from the bottom to the top. Whoever makes a decision usually does not see reality itself, but a report about reality. That is why quality here is not a mere formality. An incorrectly calculated revenue report can lead to a product being discontinued that is actually doing well.

For publicly traded companies, some reports are legally required. The quarterly report, for example, must disclose revenue and profit so that investors can make comparisons. Such mandatory reports are audited by independent experts according to fixed rules. That is why reports from companies like Nvidia or SAP often move the stock price by several percent on the day of publication.

Nevertheless, a report is never neutral. Whoever decides which figure appears in the chart and which ends up in the footnote is steering attention. A common mistake is to mistake a report for the matter itself. It is always a cross-section, chosen by people with interests.

From database entry to finished page

Technically, a report is created in three steps. First, data is collected from various sources, such as sales systems, servers, and spreadsheets. Then it is aggregated and condensed: millions of individual orders become a single figure per day. Finally, the result is presented as a table, chart, or PDF.

Today, software usually handles this process. Programs like Power BI or Tableau access a database directly and regenerate the report at the push of a button. You build the template once, and afterward it runs automatically. This is called automated reporting.

For a few years now, language models have been co-writing the accompanying text. Such a system receives the table and formulates sentences from it like “Revenue fell by four percent in June.” This saves time, but carries a risk: language models occasionally invent figures that sound plausible but are not actually in the data. An AI-written report therefore needs to be checked against the original source.

Reports you actually encounter

You already know reports, just under different names. Your music app’s yearly recap is one. The screen time summary on your phone is one. Even a school report card is essentially a report on a school year: selected metrics, fixed format, regular schedule.

In the news, reports mainly appear in two forms. First, as a company’s business report, often called an “earnings report.” Second, as an investigative report from authorities or research institutes, such as the IPCC report or safety reports from AI labs.

It is important to distinguish this from a dashboard. A dashboard is a display that updates live, like a speedometer in a car. A report is a snapshot with a date, which can be archived and reviewed again later. It is precisely this traceability that makes it useful for contracts, audits, and courts.
