Several software businesses Over the past twenty years, one of the most contentious themes among researchers has been agile software development approaches. They are known as light weight development approaches due to their flexible, informal, and adaptable methodology. The foundation of these models is an assortment of optimal methodologies that facilitate the resolution of issues pertaining to evolving specifications, client contentment, and merchandise excellence. There are several agile models available to suit the requirements of various projects. Nonetheless, the two most well-known and frequently applied models are Extreme Programming and Scrum. This study contributes much by thoroughly examining these models. This study compares Extreme Programming with Scrum in-depth in order to identify their shared and unique characteristics as well as their complementary aspects. The practice of estimating software effort is a crucial and indispensable aspect of any software project. Project success or failure is largely determined, among other things, by how accurately effort and schedule are estimated. Agile approaches’ introduction into the software development industry has brought both possibilities and difficulties for scholars and practitioners. An important problem in agile software development is estimating work. Agile software projects use traditional methods for estimating effort, however these methods typically produce estimates that are not accurate. The creation of an effort estimation model for agile software projects is the main goal of this study. A detailed explanation of the model's construction and use is provided. Abstract should summarize the contents of the paper in short terms, i.e. 15–250 words.
