Human Performance Basic's
If you’re stepping into the world of Human Performance, there’s no better place to begin than Sydney Dekker’s The Field Guide to Understanding Human Error. This video lays the groundwork for understanding why people make mistakes not from a place of blame, but from a place of curiosity, context, and compassion. Dekker has a rare ability to take a complex topic and make it feel both intuitive and deeply human.
Dekker opens by challenging one of the most persistent myths in safety: the idea that human error is the root cause of accidents. Instead of treating mistakes as the end of the story, he reframes them as the starting point for learning. This shift alone is transformative. It encourages organizations to look beyond the individual and examine the system, the environment, and the pressures that shape behavior.
For anyone new to Human Performance, this is a refreshing and empowering perspective. It moves us away from blame and toward understanding.
One of the strengths of this video is how clearly Dekker explains why people do what they do. He emphasizes that workers don’t wake up intending to make mistakes they’re trying to do a good job within the constraints and realities of their environment. When something goes wrong, it’s rarely because someone didn’t care. It’s because the system around them made the “right” action difficult, unclear, or impossible.
A particularly powerful part of the video is Dekker’s critique of outdated thinking. He doesn’t just describe old safety philosophies he shows them. He brings in actual writing from that era, including statements that essentially say:
If people would just do as they are told, everyone would be safe.
It’s a striking example of how oversimplified and unrealistic traditional safety thinking used to be. Dekker doesn’t mock these ideas; instead, he uses them to illustrate how far we’ve come and how far we still need to go.
Dekker makes it clear that the old belief just follow the rules and everything will be fine is not only false, but dangerous. Real work is messy. Conditions change. Rules can’t possibly account for every scenario workers face. And when organizations cling to the idea that compliance alone guarantees safety, they miss the deeper issues that actually lead to incidents.
His approach is a breath of fresh air for anyone entering Human Performance, because it recognizes that mistakes happen in every profession, not just in high-risk industries. Afterall, it’s call Human Performance, not robot performance! It really is a powerful message: errors are not just individual failings, but reflections of the systems and environments people work in. Whether you’re in healthcare, utilities, manufacturing, or even office administration, understanding human error as a window into how work really gets done can help organizations learn, adapt, and improve.

ReplyDeleteSydney Dekker's approach is very logical and realistic. It is important for management to understand that humans do not make mistakes simply because they want to, or because they are poor performers, incompetent, or unqualified for their jobs. There are often underlying reasons for human errors, such as poor management practices, lack of trust in employees’ capabilities, an insecure workplace environment, or other organizational factors. In many cases, human mistakes can be the result of flawed organizational decisions, systems, or policies. Therefore, management needs to carefully analyze the circumstances and reasons when errors occur. Addressing the root cause works better than treating the symptoms.
