The research report compares the Waterfall and Agile software development models to determine their effectiveness in terms of flexibility, cost, and resources. Findings indicate that the Agile model is generally more favorable for flexibility and cost-effectiveness, while the Waterfall model may require more resources due to its inflexible nature. The study involved quantitative research with feedback from software quality assurance managers and project heads in Karachi.

- 2. Abstract: The use of software’s has increased now a day. For this competition between software houses has become tougher. Because of which software houses try to attract costume by providing best services in terms of cost. Software flexibility and maintenance. The Purpose of this study was to find out which software development life cycle is better in terms of development, Cost etc. We have carried out this research through Quantitative Research Methodology. We have compare two software development models Agile and Waterfall and concluded some results based on Answers of Questions given by People Keywords: Comparison, agile, Waterfall, Analysis INTRODUCTION Waterfall model and agile model both are used in Software houses for software development. Both have different advantages and disadvantages in this research we try to find out which one is better or beneficial based on Flexibility, Cost, Time, Efficiency and Resources. This Research is very important because it will help us to make decision between Waterfall and Agile software Development Model HYPOTHESIS Agile Software Development Model is better than Waterfall Model. METHODOLOGY The Methodology we use was Quantitative Research Method in which there were 15 questions. Our Research Audience were SQA Managers, Project Heads and Project Managers Area of Research and Research Audience • Karachi • Software Houses 20(s) • SQA Managers • Project Heads • Project Manager • Quality Assurance Department ResearchQuestionnaire 1 Water Fall Model Is Cost Effective Than Agile 2 Agile Model Approach Reduces Bug Occurrence 3 Waterfall model provides flexibility to oversee the development project 4 Agile works better when scope of the project in known beforehand 5 Waterfall model works well when scope of the project is unknown 6 Waterfall model costumer presence is important through the entire project 7 In agile Costumer Presence is required only at set milestones

- 9. Conclusion In this Research, we concluded that Agile Model has Upper hand in terms of flexibility than waterfall model and Cost Effective too. When we talk about Time effectiveness of both model, we see clear opinion of people with agile model but in terms of resource people said that waterfall model required more resources because in waterfall model we cannot go back to any phase again at any time so it required more resources References For Data Manipulation http://ieeexplore.ieee.org/document/6995176/ https://ieeexplore.ieee.org/document/8241771/ https://ieeexplore.ieee.org/document/8409911 https://ieeexplore.ieee.org/document/7542304/ For Questionnaire and Study https://ieeexplore.ieee.org/document/8615505 https://ieeexplore.ieee.org/document/1201204
