#Waterfall drawing software#
Requirement specification: These analyzed requirements are documented in a software requirement specification (SRS) document.The goal of the analysis part is to remove incompleteness (an incomplete requirement is one in which some parts of the actual requirements have been omitted) and inconsistencies (an inconsistent requirement is one in which some part of the requirement contradicts some other part). Requirement gathering and analysis: Firstly all the requirements regarding the software are gathered from the customer and then the gathered requirements are analyzed.This phase consists of two different activities. Requirements analysis and specification: The aim of the requirement analysis and specification phase is to understand the exact requirements of the customer and document them properly.
These different identified solutions are analyzed based on their benefits and drawbacks, The best solution is chosen and all the other phases are carried out as per this solution strategy. The feasibility study involves understanding the problem and then determining the various possible strategies to solve the problem. Feasibility Study: The main goal of this phase is to determine whether it would be financially and technically feasible to develop the software.Let us now learn about each of these phases in brief detail: ISRO CS Syllabus for Scientist/Engineer Exam.
