This research paper discusses the software development through agile approaches. In which we see that most of the time, agile approaches cannot use for all type of projects. But this paper is exploring the new ideas that how we can use the agile methodologies with the help of traditional approach and PSP/TSP/Software CMMI. So, the over all paper is giving the whole idea, that we can develop any type of software projects through the new agile methodology guidelines which we are describing here. As well as for solving this paper we adopted different ways in which we focused on literature study & also published research paper on agile methodology. In addition, we did this work on the base of hybrid ideology where we combined the best ways of different approaches and achieved our goals.. Where we proved that by the combination of these approaches, we can manage our projects as well as team personals in the organization successfully. And this concept for team management comes from PSP/TSP and Software CMMI. The benefit for management of this is also to get our projects with agility and personnel's training for project management.
