Software engineering effort estimation plays a significant role in managing project cost, quality, and time creating software. Researchers have been paying close attention to software during the past few decades, great amount of work has done utilizing variety machine-learning techniques algorithms. In order better effectively evaluate predictions, this study recommends various machine learning...

Software undergoes changes at all stages of the software development process. Accepting too many changes will cause expense and delay and rejecting the changes may cause customer dissatisfaction. One of the inputs that help the software project management to decide whether to accept or reject the changes is by having a reliable estimation of the change effort. From a software development perspe...

Although testing effort estimation is a very important task in software project management, it rarely described the literature. There are many difficulties finding any useful methods or tools for this purpose. Solutions to other problems related calculation published much more often. also no research focusing on both and all areas of engineering. To fill gap, we performed systematic literature ...
