Agile Methodology
Table of Contents Heading
In software methodologies, Lean startup has the upper hand. The advantage is that the project gets into the marketplace often quite early. However, the modern-day agile approach was officially introduced in 2001, when a group of 17 software development professionals met to discuss alternative software developement methodology project management methodologies. Having a clear vision of the flexible, lightweight and team-oriented software development approach, they mapped it out in the Manifesto for Agile Software Development. However, poor quality can exist with iterative and traditional methodologies.
The Agile software development cycle relies on iterations — or single development cycles — that build upon each other and lead into the next step of the overall development process until the project is completed. Each iteration typically lasts between two to four weeks, with a set completion date. The goal is to have a working product to launch at the end of each iteration. Any digital project consists of the planning, analysis, design, implementation, testing and integration, maintenance stages. A set of rules is applied to mentioned stages, upheld by all team players, is called software development methodology. The Waterfall Software Development method is perhaps the oldest and most traditional of all software development methodologies. It involves a linear development process with sequential phases .
Disadvantages Of Extreme Programming Methodology:
One software development methodology is not necessarily suitable for use by all projects. Each of the available software development methodologies is best suited to specific kinds of projects, based on various technical, organizational, project and team considerations. The third step, iteration/construction, is when teams start creating working software based on requirements and continuous feedback.
As a result, software was hard to understand, develop, and maintain. A need arose for a more rigorous methodology in development of software. To compensate for the lack of logic and rigor, modular, hierarchical techniques were created and the software development life cycle was introduced. Web App Development While the waterfall methodology offers an orderly structure for software development, demands for reduced time-to-market make its series steps inappropriate. The next evolutionary step from the waterfall is where the various steps are staged for multiple deliveries or handoffs.
Scrum
Different software development methodologies enable software developers to create systems aimed at specific business objectives. These techniques have certain benefits and obstructions. But their prime focus is to provide a smooth and straightforward software development process. A “life cycle” approach with distinct phases is in contrast to Agile approaches which define a process of iteration, but where design, construction, and deployment of different pieces can occur simultaneously. In 2001, a group of experienced software developers got together and realized that they were collectively practicing software development differently from the classical waterfall methodology. A wide variety of such frameworks have evolved over the years, each with its own recognized strengths and weaknesses.
It is necessary to control the software development process in a way that ensures the quality of more reliable, maintainable, expandable systems. Rigorous design, code, and test are all essential to the development of quality software. Understanding and managing these processes helps to better understand and meet software developement methodology customer’s requirements. It is also imperative that the customer be involved during the development process so their feedback can directly improve the design. Development methodologies for software projects have evolved from a highly structured, end-to-end process into more flexible, iterative processes.
Waterfall
One software development methodology framework is not necessarily suitable for use by all projects. Each of the available methodology frameworks are best suited to specific kinds of projects, based on various technical, organizational, project and team considerations. The software development methodology framework didn’t emerge until the 1960s. According to Elliott the systems development life cycle can be considered to be the oldest formalized methodology framework for building information systems. The main advantage of Extreme Programming is that this methodology allows software development companies to save costs and time required for project realization.
Time savings are available because of the fact that XP focuses on the timely delivery of final products. Extreme Programming teams save lots of money because they don’t use too much documentation. They usually solve problems through discussions inside of the team.

The best approach for applying a methodology is to consider it as a means to manage risk. Software engineering is the practice of using selected process techniques to improve the quality of a software development effort.
This allows businesses to respond much quicker to the changing needs of their customers. So, you might want to choose this method when you are dealing with frequent changes in the project. Agile and Waterfall model are two different methods for software development process.

Each phase in the process must be completed before the next phase starts. In most cases, there is no standard mechanism to go back to a previous stage to modify the project or direction. Usually, the deliverables and scope agreed upon in the Analysis and Design phases are given concrete shape in the subsequent stages. It is a viable method for projects with clearly defined and unchanging requirements.
Though they are different in their approach, both methods are useful at times, depending on the requirement and the type of the project. The Agile software development methodology is one of the simplest and effective processes to turn a vision for a business need into software solutions. Agile is a term used to describe software development approaches that employ continual planning, learning, improvement, team collaboration, evolutionary development, and early delivery. The lean startup is more of a data-based approach in solving software development problems. It is best used by developers to speed up project works and to decrease both cost and time.
