Data or Intuition? Usually Neither
The debate between data and intuition is one of the most popular in discussions about management. On one side is the experienced entrepreneur who 'knows it in his gut'; on the other, the modern logic of numbers and indicators. The truth is that the dilemma itself is misleading. Most decisions in SMEs are based neither on good data nor on cultivated intuition. They are based on habit, on the latest incident that stayed in someone's mind, on the bank account balance that day, and very often on the voice that is heard most loudly in the meeting.
When intuition is simply ignorance
In the Greek reality, this has a specific form. Many businesses do not know their profit margin by product or by customer with precision. They know total revenue and whether the bank account is full or empty, but they do not know which part of their work sustains them and which part drains them. They decide to keep a large customer with whom they are actually losing money, or to continue a product line that only appears to perform. The decision looks intuitive, but in substance it is simply uninformed.
What data actually does
In many businesses, decisions are not made without knowledge. They are, however, often made on the basis of knowledge that has not been tested recently. The entrepreneur knows the market, the customers, the products, and the particularities of the work. This experience is valuable. The problem begins when an old certainty continues to guide decisions while reality has already changed.
This is where data is needed. Not to replace judgement, but to confront it with the actual figures. A product category may be considered successful because it 'sells'. But if it ties up large inventory, requires long credit terms, has a low margin, and takes time to turn into cash, then the picture is different. Revenue alone does not tell the whole truth.
Data-driven management does not mean that numbers decide. It means that no impression, however strong, remains unchecked.
When data becomes a trap
There is also the opposite danger, and it is worth stating because it is rarely mentioned. Data can become a trap. A business that worships spreadsheets often ends up measuring what is easy to measure rather than what matters. It fills reports with indicators that, in practice, no one looks at when making decisions, and feels that it controls the situation simply because it sees a number with two decimal places. A wrong number that looks scientific is more dangerous than an honest estimate, because it stops the discussion. The quantity of data has no relationship with the quality of the decision.
The three things that are enough
In practice, an SME does not need complex systems to make better decisions. It needs a few correct things: the real profit margin by key product or customer category; a view of how dependent it is on its two or three largest customers, because concentration is a hidden risk; and a simple cash flow forecast. These three alone change most important decisions in a small business, and none of them requires expensive software.
The criterion that matters
The most useful criterion for understanding whether one is making decisions properly is not whether there is data. It is whether the data has ever changed one's mind. If every analysis ends up confirming what management wanted to do from the start, then the data is not being used to decide; it is being used to justify. The difference between the two uses is decisive.
