Determine the different steps of Structured Requirements Definition

Step 1: Make a user level data flow diagram.

This step is meant for gathering requirements with interaction of employee. In this process, requirements engineer interviews every individual of organisation in order to learn what each individual gets as input and produces as output. With gathered data, create separate data flow diagram for each user.

Step 2: Create combined user level data flow diagram. 

Create an integrated DFD by merging old data flow diagrams. Remove inconsistencies if encountered, in this merging process. Ultimately, an integrated consistent DFD is generated.

Step 3: Generate application level data flow diagram.

Perform data analysis at system's level to define external outputs and inputs.

Step 4: Define various functionalities.

In this step, functionalities of different sub-systems and complete system is defined.
