Benefits with Agile Software Development:

• Increased Productivity / Decreased Development Costs
• Availability of options to track and review the project regularly
• Maximized project visibility
• Enhanced predictability, and adaptability
• Minimized project risk

Approach and philosophy towards Agile Development Process:

• Deployment of Adaptive method rather than predictive to allow constant change in software.
• People-oriented rather than process-oriented to allow incessant learning and usability to the development team.
• Simplest description and planning.
• Focus on high-value features.
• Tool independence that makes development process more flexible and easy to execute.

SCRUM is a specialized version of agile project management methodologies. In Scrum each iteration is called a scrum, Here iteration period can be a 1-2 Months. A client priorities his requirements what he want first. If developer did not meets all the requirement which was being fixed for a particular scrum than rest of the development part would be transferred to the next scrum (would be delivered in the next build), means developer can’t increase time decided for a scrum. It’s fixed.

The idea behind Scrum is to create a streamlined project management process that produces a quality end product.

Because the scrum process also provides much room for individual work and contribution, developers are free to devise ideas and solutions. Usually these ideas are pioneering and innovative as the team relies on the best possible formula for the completion of their work, in order to finish the project as appropriately, and as efficiently as possible.

Advantages of Scrum:

• Scrum helps the company in saving time and money.
• Scrum methodology enables projects where the business requirements documentation is hard to quantify to be successfully developed.
• Fast moving, cutting edge developments can be quickly coded and tested using this method, as a mistake can be easily rectified.
• There is clear visibility of the project development.
• Due to short sprints and constant feedback, it becomes easier to cope with the changes.
• Daily meetings make it possible to measure individual productivity. This leads to the improvement in the productivity of each of the team members.
• Issues are identified well in advance through the daily meetings and hence can be resolved in speedily.
• It is easier to deliver a quality product in a scheduled time.
• The overhead cost in terms of process and management is minimal thus leading to a quicker, cheaper result.

Extreme Programming (XP) is a software development methodology which is intended to improve software quality and responsiveness to changing customer requirements. In Extreme Programming (XP) iteration period would be less than in scrum, which is being 2-4 weeks.

The developer priorities what to do first on the basis of client requirement. This duration which was being fixed for iteration, can be increase if the some development part is still pending. The build would deployed with having all the client needs. Thus iteration period is not fixed here it can be increase, but iteration should meets all the client's requirement in this build. More attention is required for testing in XP.

Extreme Programmers work together in pairs and as a group, with simple design and obsessively tested code, improving the design continually to keep it always just right for the current needs.

Advantages of Extreme Programming:

• Extreme Programming is a discipline of software development based on values of simplicity
• XP delivers clean designs and high quality software on a realistic schedule.
• XP helps achieve a high degree of customer satisfaction.
• XP encourages a high degree of teamwork, getting the entire team (including the customer) to work together.
• Design is simple in XP.
• The whole development process is visible and accountable.
• Comprehensive test cases are generated as part of XP.
• Being able to add/modify features.
• Team is less stress.
