In order to arrive at a clear and concise definition of purpose of the reservation system, a1 discount hotels we applied soft system methodology based on the basic elements of the acronym CATWOE, which served as a checklist to stimulate focused thinking:
Client - The Senior Management of WAZOBIA AIRLINES and their prospective passengers are the direct beneficiaries of the system as it will automate their business process and also ease the way the customers interact with their services.

Ethical and social issues such as customer data protection, unreliable information causing problems for passengers are likely to arise. Some passengers might not find it easy using the systems as well as the Airline staff.
We also employed Unified Modelling Language (UML) as a visual language, through notations and diagrams, a1 discount hotels to model the reservation system using a Use Case diagram. The components of a Use Case diagram include:
Goal - is what the actor wants to accomplish a1 discount hotels by interacting a1 discount hotels with the system. Therefore use cases are all the goals that various Actors have in using the system, which are often written texts. It is shown as Eclipses with the written texts inside.
