The SHELL Model

And now for a small dose of theory…

• We have chosen the SHEL(L) Model as our visualisation tool to highlight key human factors principles during critical transfers.
• This framework, often used during aviation safety investigations, studies the interactions between individuals, the systems in which they function and the environment that influences the individuals’ activities.

• The uneven border of each component in the logo highlights the complexity and delicate nature of every interaction.

Crucially, a mismatch between us at the centre (L) and the other components can lead to human error.

• Throughout the course, we will illustrate these interfaces with relevant practical examples from aviation and explore how we can reduce the probability of an error occurring.
• We invite you to explore the various interfaces from an aviation perspective in more detail.
