There are many world accepted & standardized software development methodologies which are utilized during the software development life cycle, also known as 'Software Development Process Models'. This fixed model follows specific steps to ensure the success in the software development project.

Each phase of the software development life cycle has its own importance, and produce the required product for the next phase of the SDLC. Here is the list of six major phases that are followed in every Software development life cycle:

Requirement Gathering and Analysis: Business needs are estimated in this phase. This phase is the main point of concern for the project managers as well as stakeholders. Proper meetings are arranged among project managers, stakeholders, and users to ensure requirements such as: Who will use the system? How will they use it? What data should be input into the system? What data should be output by the system? These questions are addressed during this phase. Finally, a requirement document is created to serve as a guideline for the next phase.
Designing: In this step, the system and software design are finalized based on the requirements gathered in the first phase. This step also helps in determining hardware and system needs and defining the overall system architecture. Additionally, testers prepare a proper test strategy specifying what to test and how to test.
Coding: After the design document is finalized, the work is divided into multiple units, and coding begins. This phase provides the necessary code for software development and is typically the longest phase of the software development life cycle.
Testing: Once the code is ready, it is tested against the requirements to ensure the product meets client needs. During this phase, all types of functional testing (unit, integration, system, acceptance) and non-functional testing are conducted.

Deployment: Once testing is completed, the product is delivered to the client for use. Clients usually perform beta testing first. If any changes or bugs are found, they are fixed by software development professionals, after which the final deployment takes place.
Support and Maintenance: Once users start using the developed software, real-time issues may arise that need to be resolved promptly. This ongoing process of addressing issues and ensuring smooth performance is called maintenance.

All the aforementioned steps are crucial during the Software Development Methodologies. Follow these steps adequately, and get your desired software in a cost effective manner.
