Why to Use Agile Model for Software Development?
Software Development is a process that involves in development of software products like web application development, desktop application development, mobile application development, Custom software development etc. The life cycle of such software development differs based on the industry. But, there are few lifecycle models of software development that is approved by ISO standards. like Agile model, Waterfall model, V-Model, Spiral Model etc.
What is Agile model?
Agile model is a software development methodology used to accelerate operational product/system delivery within a scheduled time frame using set of values that include adaptability, transparency, simplicity and unity in effective and light weighted manner.
Why Agile model?
Agile model is widely practiced model which has a frequent approach in simplifying the process by dividing it into short and light weighted phases such as Requirements, Specification, Architecture, Design, Implementation, Testing, Deployment and Maintenance that results in effective software systems.
Advantages of Agile model:
• Reduce the engineering time and assures on timely delivery.
• Decreases the cost of engineering by reducing the risk and errors factors.
• Constant testing eliminates error and assist in software reliability
• Accomplishes faster return on investment by better improvement on the system at regular intervals
Requirements: The requirement phases are classified as functional and non functional specifications. Functional specification involves in features and interactions required by the user/client. And the non functionality includes the needs of performance, design and quality standards of developing the software.
Software development is of two types based on the customer requirements. They are: Customized software development which is developed to meet the needs of the user, and embedded software development is one developed to automate some specific tasks.
Design: The Design phase is also further classified into two phases. Fundamental Design and methodological Design
Fundamental Design is one which delivers the information on the needs of functionality and usability by the client/business to developer on the first phase. Technical Design is the featured design of a developer on how to meet the requirements of the software as on the fundamental design. The entire architecture of the system is designed by the developers after corresponding with the clients. This avoids the unnecessary work and helps to concentrate on good functional design constantly.
Development: This phase involves in implementing and executing the source code in order to realize the software application as designed in technical design specifications.
Testing: The phase in which the developed and executed source code is integrated, and tested for the performance, design and quality measures. In agile model testing plays a major role since every small module is tested for the reliability throughout the project.
Support: The tested software product is deployed as a system based on requirements and delivered within scheduled time. The software maintenance are classified in two phases, Administrative Maintenance and Technical Maintenance.
Administrative maintenance includes maintenance cost, training and staffing, client precedence and configuration. Technical maintenance includes impact analysis, debugging and fixing, testing, maintenance measurement.
At TreeShore, We use agile model for Software Development to take a static view on requirements of clients which enables us to provide solutions based on their demand on time by maintaining a sustainable pace of development with self motivated developers.
