Software has changed the world in the last couple of decades and when we talk about Information Technology, Tech organizations, and Tech enthusiasts around the world are indulging in innovating new software and programs time and again. <\/span><\/p>\n

It is a fact that the success of any software solution depends on the methodology and the quality of efforts invested in the development process.<\/span><\/p>\n

Before software development<\/span><\/a>\u00a0models were introduced into IT organizations, the development process was often ambiguous and inefficient, producing inconsistent and unpredictable results.<\/span><\/p>\n

The use of standardized frameworks and models helped reduce the mismatch in product expectations and delivered prototypes.<\/span><\/p>\n\n

<\/span>What is Software Development Methodology?<\/span><\/span><\/h2>\n

A software development methodology is broadly a framework that is utilized by the software development team, that enables them to design and develop various kinds of software applications while keeping a tab on requirement analysis, meeting budget while containing risk, and providing value to their customers.<\/span><\/p>\n

Software methodologies are defined to ensure the software development work remains smooth, and non-distracting for the developers, with a proven standard operation procedure, effective communication, regular meetings, and an optimized workload.<\/span><\/p>\n

\"software<\/p>\n

In a nutshell, we can also say that a software development methodology<\/span> <\/a>is a group of repeatable processes that should be followed by software development organizations\/developers to achieve successful results.<\/span><\/p>\n

These processes create the foundation for a successful project and have proven to be helpful in the development of quality software.<\/span><\/p>\n

The two most popular software development methodologies are Waterfall (SDLC) and Agile. Both are commonly used for the development of software projects and project management as well. <\/span><\/p>\n

Though we will discuss in detail the difference between both approaches, the most common difference between SDLC and Agile is that SDLC is a sequential approach whereas Agile is iterative in nature.<\/span><\/p>\n\n

<\/span>What is SDLC?<\/span><\/span><\/h2>\n

Software Development Life Cycle (SDLC) is a process that helps us develop software with the lowest cost and highest quality in the shortest time possible. <\/span><\/p>\n

SDLC offers a well-structured flow of different phases, which helps an organization to develop software in a well-structured way, and it also helps to maintain the quality, while carrying out testing and validation of the user specifications, before putting the software into a live environment.<\/span><\/p>\n

SDLC is also known as an Application Development<\/span> <\/a>Life Cycle, it can be applied to the development of both hardware or software components or configuration to define its scope and life cycle process. <\/span><\/p>\n

SDLC model is an amalgamation of both iterative and incremental process models and has a better focus on customer satisfaction and process adaptability by ensuring quick delivery of a workable software solution.<\/span><\/p>\n\n

\"Software<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Requirement Gathering and Analysis\u00a0<\/span><\/h3>\n

This is the first phase of SDLC, in which it is determined that we really need some software or application to solve any kind of problem. In this phase, the requirements are assessed, inputs are taken from all stakeholders, and the shortcomings of the current system and the strength and pitfalls of the proposed system is discussed and documented accordingly. <\/span><\/p>\n

In this stage, a Project Manager and a Business Analyst schedule meetings with the Customer, to gather all the information like the customer\u2019s needs, expectations, process flows, the value expected, and the purpose of the product. <\/span><\/p>\n

It is important to have a core understanding of the product before initiating the second phase of SDLC.<\/span><\/p>\n

Design\u00a0<\/span><\/h4>\n

In this phase, we use the output of the initial phase, the SRS document (Software Requirement Specification) as input and derive a software architecture that will be used for implementing system development.\u00a0<\/span><\/p>\n

This phase also helps in identifying and specifying the system and hardware requirements and helps in defining the overall programming language framework, database architecture, and system architecture. <\/span><\/p>\n

The system design specifications are used as input for the next phase of the model.<\/span><\/p>\n

Implementation\/Coding\u00a0<\/span><\/h4>\n

This Implementation\/coding phase starts once the software developer team gets an adequate Design document. Upon receiving the system design document, the Project Manager divides the work into small modules\/units, and actual coding work is started. <\/span><\/p>\n

This one certainly is the most crucial and longest phase of the SDLC life cycle. In this phase, the Software design is translated into the source code, and all the components of the software system are implemented in this phase only.<\/span><\/p>\n

Testing\u00a0<\/span><\/h4>\n

Once the software code is developed, it is necessary to test it against the specified requirements, to ensure if the developed code is fulfilling the requirements defined in the first phase or not. <\/span><\/p>\n

In this phase, every kind of functional testing like integration testing, system testing, unit testing, and acceptance testing are performed along with several kinds of non-functional testing.<\/span><\/p>\n

Deployment\u00a0<\/span><\/h4>\n

Once the quality testing<\/a>\u00a0is completed, the product is delivered or deployed at the customer\u2019s end. It could be an executable file installed at the customer\u2019s premises or could be an application hosted on Cloud to ensure seamless access to the customer remotely.<\/span><\/p>\n

Maintenance\u00a0<\/span><\/h4>\n

Once the software is deployed, it is required to provide adequate support and maintenance<\/a> procedures to ensure it runs without any issues, and to enhance the end-user experience. <\/span><\/p>\n

This phase gives us an opportunity to counter the problems, develop the knowledge base, and execute the regular maintenance work like software up-gradation, patching, etc.<\/span><\/p>\n\n
