Program Plan Intro

Software Development Methodologies:

The different software development methodologies are as follows:

• Agile methodology
• Waterfall methodology
• Rapid application development (RAD) methodology
• Extreme programming (XP) methodology
• Rational Unified Process (RUP)
• SCRUM

Agile methodology:

This methodology targets the customer satisfaction by delivering the software components quickly and continuously to the customer. This process is carried over by an iterative process, which uses minimum requirements.

Waterfall methodology:

Waterfall model is considered as an activity based process. Here every phase of SDLC is being accomplished in sequential manner.

Rapid Application Development (RAD) methodology:

This method highlights huge user involvement in the rapid and evolutionary structure of working prototypes for a system that accelerates the system development methods.

Extreme Programming (XP) methodology:

This methodology is used to divide a project into four phases such as planning, designing, coding and testing. Here the developers are not able to move to the next phase until the preceding phase is complete.

Rational Unified Process (RUP):

This method is used for separating the development of software into four gates such as inception, elaboration, construction and transition. Every gate contains the software executable iterations in development.

SCRUM:

This method is based on team. The team is to delivering the small pieces of software using a “sprints” or “30-day interval” to reach a specific goal.

Explanation of Solution

Choice of methodology for building a social networking website:

To develop a social networking website, the SCRUM methodology is chosen. The reasons and advantages for choosing the SCRUM methodology are as follows.

Reasons for choosing SCRUM method:

• Scrum methodology is a well-organized framework, which is used to develop the software by using teamwork based approach.
• In this methodology, the team is to deliver the small pieces of software using a “sprints” or “30-day interval” to achieve a specific target. The term “sprint” means duration of two to four weeks to complete a part of project.
• To check and control the development effort, the meeting will be held in the ending section or beginning section of each day.
• Therefore, the scrum technology will provide for a quick turnover approach for developing and testing the social networking site.

Advantages of using SCRUM methodology:

• Scrum methodology is easy to implement and it aims on fast and frequent deliveries.
• Using scrum methodology, removing mistakes or correction will be easier.
• The visibility of all phases of the process during its development will be clear.
• The productivity is improved in this methodology.
• Since using short sprint and continuous feedback from user, then easily manages with modifications.
