Indeed, ITIL (Information Technology Infrastructure Library) roles can be compared to the characters in Agatha Christie's novel "Murder on the Nile" (also known as "Death on the Nile"). Just as each character in the story plays a distinct part in the unfolding of the plot, each ITIL role is responsible for specific tasks and functions within an IT organization.

Here's a comparison between ITIL roles and the characters in "Murder on the Nile":

• Incident Manager: Hercule Poirot, the famous detective, can be compared to the Incident Manager. Poirot is responsible for investigating the murder and finding the culprit. Similarly, the Incident Manager is responsible for identifying, analyzing, and resolving IT incidents to restore normal service as soon as possible.

• Problem Manager: Colonel Race, a friend of Poirot who assists him in the investigation, can be compared to the Problem Manager. The Problem Manager identifies the root cause of recurring incidents and searches for long-term solutions to prevent them from happening again.

• Change Manager: Simon Doyle, the newlywed husband of the murder victim, plays a significant role in the plot. His actions lead to major changes in the story. The Change Manager, like Simon, is responsible for managing changes in the IT environment to minimize disruption and risk.

• Service Level Manager: Jacqueline de Bellefort, the ex-fiancée of Simon Doyle, can be compared to the Service Level Manager. She is deeply concerned with the quality of the relationships between characters, just as the Service Level Manager is responsible for ensuring IT services meet the agreed-upon performance standards and quality.

• Configuration Manager: Mrs. Allerton, a keen observer of the passengers on the ship, can be compared to the Configuration Manager. This ITIL role is responsible for maintaining an accurate and up-to-date record of the IT infrastructure and its components, ensuring that any changes are well documented.

• Capacity Manager: Dr. Bessner, a physician on board the ship, is responsible for the well-being of the passengers. He can be compared to the Capacity Manager, who ensures that the IT infrastructure is capable of meeting current and future demands.

• Service Continuity Manager: Fleetwood, the ship's captain, can be compared to the Service Continuity Manager. Captain Fleetwood is responsible for navigating the ship safely through the Nile, just as the Service Continuity Manager is responsible for ensuring that IT services can continue even in the face of unforeseen events or disasters.
