Agile development software methods are certainly for software developers since 2001. There are so many agile methods that make it a bit of a challenge to choose the right project. The simplest way to read the advantages and disadvantages of the three most popular methodologies is to find out which one is right for you and your project.  Scrum
Developed by Jeff Sutherland and Ken Schwaber, this method involves one or more small groups (ScrumMaster, product owner and developer team) who work together to implement a project based on a prioritized list of tasks. This is done by dividing the list into shorter times that are completed under a "sprint" or during a defined 2-4 week development period. While this is one of the most popular agile development software methods, the problem is that most programmers consider it necessary to integrate other methods to cover additional exercises that are not part of agile scrum.
2) Dynamic System Development Method (DSDM)
DSDM is a versatile method, but the latest and popular version of the DSDM Atern method. This approach focuses primarily on projects with close timetables and budgets and follows eight core principles:
• Focus on Business Needs
• Work on time
• Effective collaboration
• Never compromise on quality
• Build the project with gradual solid foundation
• Project implementation is iterative
• Communicating constantly with the light
According to the rigor and the eight principles, DSDM Atern's main problem is that it is limited and difficult to work with other agile development software.
3) Extreme Programming (XP)
XP, developed by Kent Beck, the methodology is somewhat similar to Scrum as it uses a "time schedule" or short development cycle throughout the process. It helps to reduce costs as a lengthy process and helps keep the project dynamic and adaptable. This method requires four activities:
• Encoding – where software or software is actually encrypted
• Testing – where the encoded product is tested
• Listening – where developers listen to the needs and suggestions that customers or customers report after testing
• The design – where developers organize and plan the logic of the system based on their experience of the first three activities
This agile development software method is more popular compared to a more restrained and non-restrictive method, lacking a solid structure, without doing so.
Based on the advantages and disadvantages listed above, you probably have a good idea of which method to do now. If you want to do something more disciplined while still sticking to the faster concept of speed, go to DSDM Atern. If you feel that the project benefits from an older process that allows your developer team to get the wheel cutter and make them creative, then XP or Scrum. If none of these three methods are attracted to you, do not be discouraged – there are a lot of other agile development software methodologies you can choose from; it's just a method that meets the needs of the project.
