Building a software\/app of your own is a tedious task if not approached correctly. Besides finding the right development team, you must also identify the exact flow of building the application.<\/p>\n

While the concept of breaking down the entire development process into stages is not new, you must have a proper understanding of what approach to choose and which will be the most fruitful for you.<\/p>\n

Generally, the two most preferred approaches are Software Development Life Cycle & Agile Development. Each of these approaches has its perks and drawbacks.<\/p>\n

However, when it comes to choosing the one for your project, things can get confusing as the contrast between the two can be deceiving.<\/p>\n

While one focuses on flexibility, the other focuses on a step-by-step approach. Over the years, both of them have proven to be effective, based on different factors.<\/p>\n

So, which one to choose?<\/strong><\/p>\n

Well, that is the question that we are going to answer in this post. By the end of this one, you will be able to identify the differences, benefits, and drawbacks of choosing the SDLC or Agile Development approach.<\/p>\n

We will also help you navigate through the factors that can help you choose the right development structure. So without further ado, let\u2019s begin!<\/p>\n

<\/span>Why is Choosing the Right Approach Crucial?<\/span><\/h2>\n

A development model or methodology defines the course of action that a developer takes to complete a project.<\/p>\n

The entire process of developing and building an application has several stages, each of which plays a significant role in the final product.<\/p>\n

A development methodology helps you focus on all the minute details of the process.
\nIt helps you identify all the basic and advanced requirements of the application, including –\u00a0<\/strong><\/p>\n

    \n
  1. Plan the process to meet the timeline.<\/li>\n
  2. Be aware of regulations and compliance.<\/li>\n
  3. Keeping the entire process under budget.<\/li>\n
  4. Create a workflow for ease of completion.<\/li>\n
  5. Breaking down the process for effectiveness.<\/li>\n
  6. Curating the right team to finish the project.<\/li>\n
  7. Bringing together the perfect pool of tools & tech.<\/li>\n<\/ol>\n

    All in all, identifying the correct software development approach\/methodology<\/a> can be a game-changer for any project. However, you should keep in mind that while these approaches are often considered one-size-fits-all, they are not the same. For different circumstances and requirements, different methodologies can be used.<\/p>\n

    <\/span>Software Development Life Cycle (SDLC) in a Nutshell<\/span><\/h2>\n

    The software development life cycle, popularly known as SDLC, is a development methodology that takes every step into account and follows a sequence of steps.<\/p>\n

    The idea behind this approach is to be 100% sure of what you are building and act accordingly. This is considered to be the ideal approach for people looking for cost-effective and optimized development.<\/p>\n

    The SDLC provides a thorough framework for building software from scratch while focusing on the timeline suggested by the client.<\/p>\n

    That is because, unlike any other approach, there are stages in this one that have a pre-defined timeline for completion.<\/p>\n

    This means when the idea is discussed, you have a rough idea of how long it will take to complete the project.<\/p>\n

    \u25ba Stages of SDLC<\/h3>\n

    Here is a breakdown of all the stages involved in the software development<\/a> life cycle that will help you optimize your development process to the best of your ability.<\/p>\n

    \"Stages<\/p>\n

    Stage 1 – Project Planning<\/h4>\n

    This is the stage where the scope of the application is defined. Everything from how to build the application to how the final product will look. The objectives have been decided to begin the process.<\/p>\n

    Stage 2 – Gathering Requirements<\/h4>\n

    Once the objectives have been decided, all the necessary resources are gathered. The requirements to reach those objectives are addressed, and every necessary resource is acquired.<\/p>\n

    Stage 3 – Project Design<\/h4>\n

    Based on the requirements, the design of the application is as follows. The system architecture is crafted at this stage. The professionals ensure that the frameworks have all the necessary elements.<\/p>\n

    Stage 4 – Developing the Software\/App<\/h4>\n

    With a defined project design, it is time to define the development of the functionalities according to the design elements. This is the stage where the code is written to implement the decided features.<\/p>\n

    Stage 5 – Testing Functionalities<\/h4>\n

    After every feature is integrated into the designed structure, the functionalities are tried and tested. This stage ensures that all the requirements of the client are met, functionalities are working properly, and there are no bugs.<\/p>\n

    Stage 6 – Final Deployment<\/h4>\n

    Planning the deployment refers to launching the final build and making it available to the public. The final build is extracted and then set for a launch in relevant environments and stores.<\/p>\n

    Stage 7 – Maintenance & Management<\/h4>\n

    The job is not over after you have deployed the final software\/app. Since the product you have built is now being used by regular users and that too in different environments, you must stay attentive to maintenance & management.<\/p>\n

    <\/span>SDLC Phases: Software Development Life Cycle Models<\/span><\/h2>\n

    When implementing SDLC, you can choose from a range of development models that you can follow.<\/p>\n

    Each step in the SDLC is defined as a phase, and based on the flow of these phases, the models of SDLC are classified.<\/p>\n

    The classification of these models includes –<\/p>\n

    Waterfall Model:<\/strong> A popular approach used in SDLC, the waterfall model states that every phase of the development flows downwards, just like a waterfall.<\/p>\n

    Each stage is completed before the next one begins. The model uses a linear approach, which makes it easier to understand and implement.<\/p>\n

    Iterative Model:<\/strong> As the name suggests, this development model works in iterations. This model allows you to break down the entire project into small portions, and with each portion being completed, a new value is added to the final solution.<\/p>\n

    This means that with every iteration, your app will have a new feature.<\/p>\n

    Spiral Model:<\/strong> No, this is a hybrid model built with characteristics from both waterfall and iterative models of SDLC.<\/p>\n

    It focuses on identifying the objectives of the cycle to determine if there are alternative ways to achieve the goal. Once that is secure, you need to identify strategies to help you solve uncertainties and risks. This is the model that promotes prototyping and benchmarking.<\/p>\n

    V-Model:<\/strong> Also referred to as the Validation and Verification model, the V-model is a variation of the waterfall model.<\/p>\n

    The only difference is that after every phase is completed, testing is implemented so that the performance of each stage can be validated and verified accordingly.<\/p>\n

    Big Bang Model:<\/strong> Now, this is the model that requires all the SDLC stages to be implemented simultaneously.<\/p>\n

    There is no working your way up to the finale, no iterations, nothing. It is just like a big bang, which means the process is finished, and you realise the outcome.<\/p>\n

    There is no set destination you need to reach, making it more and more difficult to try with complex projects.<\/p>\n

    Based on the choice, these models define the approach of the SDLC. Each of them has its pros and cons, so that is a decision for you to take.<\/p>\n

    However, it is understandable that SDLC offers you a whole lot of ways to suit your process and allow you to make the right decisions while developing your solution.<\/p>\n

    \u25ba Advantages of Using SDLC<\/h3>\n

    The entire process of software development life cycle offers a series of advantages.<\/p>\n
