Program Plan Intro

Software Development Methodology:

Different methodologies in software development:

• 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 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

Reasons for choosing agile method:

If one were consulting a business in which he wants to build a video game for the iPhone, he can choose the 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.

Users can develop the best software product using this methodology. So the teamwork and perceptibility can offer a better knowledge for given teams.

Advantages of using agile methodology:

• It is fast and efficient method with lesser cost and features.
• This methodology is used to improve feasibility and supports the procedure for receiving fast response as functionality is presented.
• The unclear requirements are being clarified to its developers, as the developer proceeds towards the process.
• This methodology is helpful to keep the accountability and also helps to set up an indicator for end user satisfaction.
