TIME AND COST OF QUALITY IN SOFTWARE VERIFICATION

A COMPARATIVE SURVEY OF RUP, EVOLUTIONARY PROTOTYPING, AND SCRUM

Resumen

Quality assurance has become a fundamental component of modern software development, as
project success is increasingly linked to the ability to deliver reliable and high-quality software within
defined time and budget constraints. As a result, understanding how time and cost are affected by quality-related activities has become a major concern for organizations. This paper analyzes the role of the
Time of Quality (ToQ) and the Cost of Quality (CoQ) within the software verification process of projects
developed using three different methodologies: the Rational Unified Process (RUP), evolutionary prototyping, and Scrum. Through a comparative analysis of how each methodology integrates testing and
verification activities throughout the software development lifecycle, the study highlights differences in
the estimation, management, and impact of quality-related time and cost. The results provide a conceptual reference to support the selection of a software development methodology based on its ability to
manage quality assurance efforts while balancing time and budget constraints
