Many consider the agile practice of extreme programming as the most effective approach to maximize the benefits derived from the programming cycle. Extreme programming emerged after problems arose in the traditional software development cycle model. Its introduction focused on ‘simply getting the job done, and it was adequate for the development. Extreme programming is tried and tested agile development practice; it puts maximum focus on customer interaction to know the exact requirement and then only get into the development of the product.

Functioning of Agile Programming

It divides the whole cycle of processing into smaller or short cycles. During the development phase, or the stage before delivery (the last stage), the customer can make changes based on his requirement.

It works in five phases:

1. Exploration 2. Planning

The team divides the collected data into small cycles to comprehensively understand each aspect of the user’s requirements. The team prioritizes the data for the first release of the product and proceeds with the development process. The estimation and schedule of efforts for the first release are calculated and then agreed on the release. The first release span is under two months.

3. Iterations

During this stage, several system iterations occur before the first product release. The iterations are divided into several small and given two to four weeks to implement. The iteration planning phase is currently in progress, involving the determination of cycle division, prioritization of requirements, and allocation of the necessary workforce for development. The iterations form the system’s foundation by selecting cards from the user-created story cards, ultimately leading to the realization of the system. The user decides which one to select first. The customer runs iteration at the end of every slot, which he has decided for each iteration part.

4. Productionizing

The production continues to operate after the product’s initial release, whether it is for the same product or subsequent iterations. The maintenance team is asked for corrections in defects during this phase, done after the product’s first release. Communication with the customer can also ask through the customer support desk. Maintenance may necessitate the establishment of a structure due to the addition of new team members or changes within the team.

5. Death Phase

This is the phase when the customer agrees on no more story cards for implementation. During this phase, the team can complete the final documentation for the product, assuming they will not make any further changes to the architecture, design, or code. To ensure the delivery of the desired product, the system will be deemed inactive. It should keep the expenses within the limit for further development.

Team (Role and Responsibility)

Agile cycles have several members (team) for creating the new product. The team divides and assembles every task, ensuring they execute each task effectively.

Programmer: The programmer is one of the main bodies; he creates the code for the product and keeps the code simple and definite to possibility. The best way to code correctly is to communicate throughout with other programmers and teammates. It can be for knowing the exact requirements for the product.

Customer: The customer is the main body to write story cards for his requirements and decides which requirements will satisfy his needs. The customer sets the implementation priority.

Tester: The tester is responsible for running functional tests; he helps the customer to write functional tests. The team performs testing regularly throughout the development process and actively maintains testing tools.

Tracker: Tracker provides feedback, keeps track of the team’s estimates, and provides suggestions to improve.

Coach: The coach guides the team members throughout the development process. He is the experienced one who has been in processing for many years.

Consultant: The external member provides the team with the specific technical knowledge required for project development, guiding them along the way.

Manager: He is the deciding body. The Manager maintains the team’s focus to accomplish the work. He is open to communicating with team members regarding issues faced during development. He ensures the smooth progress of the work until delivering the project.
