Have you ever considered that reliability is not just a personality trait? Something we either have or don’t have? In reality, it is a skill of the brain – a combination of memory, attention, and self-regulation. In the workplace, it affects not only our own results but also the performance of others. And when it is missing, it can disrupt the functioning of an entire team or even a company.
Unreliability rarely shows up as one big, visible failure. Instead, it creeps in gradually through small things: a forgotten task, a postponed deadline without communication, or a missed meeting without an apology.
Yet, these small things add up. One broken commitment delays another. Tasks come back, need reminders, and require checking. Instead of smooth workflows, delays and time losses occur. At the same time, people’s behaviour within the company begins to change. They start double-checking each other’s work and trusting each other less. Trust is essential for a team to function effectively.
Unreliability is therefore not a minor issue that can be ignored. It is a factor that can significantly impact performance, company culture, and in extreme cases, even the company’s existence.
The importance of reliability for companies – especially in times of economic uncertainty, risk aversion, and increasing dependence on artificial intelligence – is highlighted, for example, in this article.
1. Team stress
When people cannot rely on each other, they must constantly monitor, remind, and create their own “safety nets.” This leads to ongoing tension.
2. Loss of time
Time is not only lost because something isn’t done. It is lost in searching, repeating, and explaining. In returning to the same issues again. Unreliability creates hidden administrative work that no one planned.
3. Frustration and declining motivation
When someone repeatedly fails to deliver on promises, others gradually disengage. They stop investing energy. Why should they, if the outcome is uncertain?
4. Growing mistrust
Trust is built through small, repeated experiences – delivering, responding, being on time. Once these “micro-experiences” are disrupted, trust declines faster than we realise.
5. Strained relationships
Unreliability also has a personal dimension. It leads to tension, silent conflicts, distance, weakened relationships, and sometimes even the loss of friendships, which in many workplaces are built on trust.
6. Loss of trust in leadership
If reliability is essential for anyone in a company, it is for leaders. A leader who does not keep their word loses authority – not immediately and loudly, but gradually and quietly. People simply stop taking them seriously.
7. Damaged company culture
Company culture cannot exist only on a website – it must be lived. If unreliability is tolerated, it becomes the norm. And norms tend to spread quickly in the workplace.
In practice, reliability is not just about keeping promises. It is often described using the 3C model, which shows how people build professional credibility:
Only the combination of these three elements creates reliability that others can truly depend on.
Let’s now look at reliability from a different perspective – from the point of view of how the brain works. It is based on three key pillars that determine whether we actually follow through on our commitments:
1. Memory
We often write down deadlines and commitments. However, we cannot rely solely on these “external supports.” Memory needs to be consciously strengthened. The ability to retain and work with information over time is essential for reliability.
2. Self-regulation
This means the ability to decide when and how to complete a task and to consciously manage priorities. It also includes assessing whether we can realistically meet what we promise. It requires knowing what matters, translating it into action, and following through even when it is uncomfortable.
3. Attention
The ability to be mentally present at the moment a commitment is made. If we are not fully focused, we often fail to encode the agreement. Today, our attention is overloaded, which is why it also needs to be trained intentionally.
Reliability should therefore not be seen as a fixed personality trait that we either have or lack. It is a specific brain-based skill that can be actively developed by strengthening memory, training attention, and improving self-regulation.
I help my clients optimise their brain settings so they can maintain focus, stable performance, and reliability – even in demanding situations.
