The most valuable decision a manager makes is not the one that generates profit. It's the one they can explain

In the business world, there is a natural fascination with results. End-of-quarter figures, the value of signed contracts, turnover trends, or the return on an investment are the benchmarks against which most management teams are evaluated. When indicators are favourable, few still ask how the decisions that led to that outcome were made.

However, the law views matters from a different and, in many cases, far more demanding perspective. An inspired decision does not automatically become a responsible one merely because, in the end, the company profited. By the same token, a project that failed to achieve its objectives does not, in itself, prove that the director or executive acted wrongly.

The legal concept that draws this distinction is termed diligence (due care), and its significance extends far beyond the pages of commercial law textbooks. In reality, it influences almost all the key decisions that a company's leadership takes throughout its existence, even if very few managers use this term in their day-to-day work.

Suppose a company approves a major investment following months of analysis and negotiation. However, the economic context changes radically, the market responds differently from initial estimates, and the project generates significant losses. In retrospect, it is easy to assert that the choice was wrong. It is far more difficult to answer the question that the law actually raises.

Was the process by which that decision was reached prudent, informed, and reasonable?

This is the fundamental question.

Not because the result does not matter, but because the law recognises a fact that business experience confirms almost every year: no one can control all the variables that affect the success of an investment. Legislative amendments, tax changes, economic crises, geopolitical conflicts, or technological developments that are impossible to anticipate precisely may arise. Requiring a manager to guarantee the outcome would mean demanding the impossible.

Instead, they may be required to demonstrate that they did not decide superficially, that they analysed the available information, assessed the foreseeable risks, listened to the opinions of the specialists involved, and chose the solution that, at that moment, any prudent professional could have considered justified.

The difference between these two perspectives fundamentally alters how the work of a management team must be viewed.

The legal counsel does not attend key meetings merely to verify whether a document complies with the law or whether a contract contains all the necessary clauses. Their contribution begins much earlier, when they monitor how the decision-making process is constructed and observe whether the organisation will be able to explain, years down the line, the reasons why it chose a particular course of action.

This concern sometimes appears excessive. During periods when the company operates smoothly, documenting analyses, recording arguments, and retaining the opinions of specialists may seem like mere administrative formalities. However, the situation changes radically the moment the decision is scrutinised by shareholders, authorities, or a court of law, and someone must prove that the choice was not the result of intuition or improvisation.

The true value of diligence does not lie in eliminating the risk of error, since such an objective cannot be achieved in any economic activity. Its value lies in transforming the decision-making process into an exercise of accountability, capable of withstanding objective scrutiny even when circumstances have made it impossible to achieve the desired outcome.

Perhaps precisely for this reason, mature companies do not build their organisational culture exclusively around performance, but also around the discipline with which key decisions are made. Profit may confirm that a choice was inspired, but only diligence can demonstrate that the very same choice was made with the responsibility that the law expects from those who lead an organisation.
