Following the Preliminary Investigation Report (Stage 1 assignment), the next step is to identify the requirements for a system, documenting them in the Requirements Specification document.

Following the Preliminary Investigation Report (Stage 1 assignment), the next step is to identify
the requirements for a system, documenting them in the Requirements Specification document.
The purpose of the Requirements Specification is to clearly define what the proposed system will
do in non–technical user–oriented language. It should identify what data is entered into the
system, what output is required, what processes the system should perform, what protections and
controls are needed, what performance is expected, and what the business continuity needs are.
In order to clearly express the requirements, data and process models are used to communicate
how the system should work.
Task
1. The input–processing–output requirements must relate to each other. Start with three
outputs you expect from the system, then determine what inputs are needed to create each
of those outputs, and finally specify what processing needs to occur for each input to
create the output.
a. List three different reports, results of a calculation, or other outputs.
b. Input requirements are the main data elements required to create the output.
c. Processing requirements are the processing required to create Output

2. Prepare a context diagram for the new system.
