The purpose of this spreadsheet is to present an example of detailed requirements for a data import interface. The example is part of the Trips-R-You Flight Booking Case Study. It's purpose is to provide an integrated, end-to-end set of requirement examples. 

The following high-level requirement identifies the need for this interface:

"The system shall be able to request scheduled options for a trip from the GDS."

Section 3.5 of the case study presents the scenario describing detailed discussions with stakeholders about their needs related to the above requirement. These discussions lead to the example detailed business requirements documented in this spreadsheet and the Data Dictionary. When those discussions were concluded, and the contents of this spreadsheet reviewed and signed-off, the following  'formal' detailed requirement was produced to represent the detailed requirements for this interface:

"The system shall be able to obtain Scheduled Options for a Trip from the GDS - as specified in DR016 - Trip Scheduled Options from GDS v1.1."
