Why reporting becomes a problem as a business grows
Reporting rarely starts as a problem. It becomes one gradually, as each department builds what it needs.
The same metric has several definitions. Each report calculates cost of goods, margin or service level in its own way, so two people can present different answers to the same question and both be technically right.
Reports are built one request at a time. Every new question becomes a custom extract, which takes time and leaves behind dozens of near-duplicate files.
Spreadsheets are the glue. Exports from several systems are merged by hand, which is slow, error-prone and depends on whoever built the file.
Heavy queries hit the live system. Running large reports directly on a production ERP can slow down the operation it is supposed to describe.
Nobody can tell how fresh a figure is. Without a visible refresh time, readers do not know whether they are looking at this morning or last month.
