Software Development Agile Methodology

Software Development Agile Methodology

In this article, we are going to discuss the agile methodology  its key features, phases, testing methods, and its pros and cons during software development process. Our ever expanding digital world has a growing hunger for more complicated and diverse applications. Unfortunately, this demand collides with high software development failure rates. To address this failure Agile Methodology came into existence.

The Agile methodology began as a novel technique to manage software development in the software development business. Many software development projects were failing or taking far too long to complete, and industry leaders understood they needed to come up with a new, creative solution.

The Iterative Waterfall model was formerly a common way to finish a project. However, today’s developers confront a number of issues while using it to create applications. The key challenges were dealing with customer change requests during project development, as well as the significant cost and time required to make these changes. Therefore, The Agile Software Development Manifesto was created in 2001.

Agile was originally designed to manage software development projects. It has, however, grown to manage projects across all industries, companies, and markets. Now let’s deep dive into the topic and learn more about Agile Methodology

What is the Agile Methodology?

Agile refers to something that is quick or adaptable. A software development approach based on iterative development is referred to as an “agile process model.” Agile approaches divide projects into smaller iterations or sections and avoid long-term planning. The scope and requirements of the project are defined at the start of the development phase. The number of iterations, duration, and scope of each iteration are all clearly determined ahead of time. Unlike the Waterfall paradigm, both development and testing operations are contemporaneous under the Agile Methodology of software testing.

In the Agile process model, each iteration is a small-time “frame” that lasts anywhere from one to four weeks. This time frame is termed as  Time Box i.e. the amount of time taken to finish an iteration. The greatest length of time required to provide an iteration to clients is referred to as a time-box. As a result, the end date for an iteration remains unchanged. Though, if necessary, the development team might choose to limit the delivered functionality during a Time-box in order to meet the deadline.

The delivery of an increment to the client after each Time-box is the basic principle of the Agile approach. The segmentation of the complete project into smaller pieces helps to reduce the total project delivery time requirements while minimizing project risk. Before a working product is demonstrated to the client, each iteration requires a team to go through the entire software development life cycle, which includes planning, requirements analysis, design, coding, and testing.

The four essential values of agile software development are highlighted:

  1. Interactions between individuals and groups about processes and tools
  2. Working software takes precedence over thorough documentation.
  3. Collaboration with customers is preferred over contract negotiations.
  4. Adapting to change in accordance with a strategy
Phases of Agile Methodology

Different phases of Agile Methodology are defined in the below points;

  1. Requirement Gathering: You must define the criteria at this step. You should describe the project’s business opportunities and estimate the time and effort required to complete it. You can assess technical and economic feasibility based on this information.
  2. Design the requirement: Work with stakeholders to define requirements once you’ve defined the project. To demonstrate how new features function and how they will fit into your existing system, use a user flow diagram or a high-level UML diagram.
  3. Develop/Iteration: The work begins once the team has defined the requirements. Designers and developers begin work on their projects, with the goal of releasing a functional product. The product will go through several stages of development before being released, thus it will have basic, rudimentary functionality. Ultimately, deploying a non-static product or service.
  4. Test: This phase basically involves the testing team i.e. the Quality Assurance team checks the product’s performance and seeking for the bug during this phase.
  5. Deployment: The team creates a product for the user’s work environment in this phase.
  6. Review / Feedback: The final phase is to get feedback after the product has been released. This is where the team receives feedback on the product and works through it.
Advantages of Agile Methodology
  1. Communication with clients on a one-on-one basis.
  2. Continual Delivery
  3. Design that is both efficient and meets the needs of the company.
  4. Changes can be made at any moment.
  5. It cuts down on overall development time.
  6. Customer satisfaction is defined as the development and delivery of valuable software at a rapid pace.
  7. Customer, Developer, and Product Owner meet on a frequent basis to focus on the customer’s needs rather than processes and tools.
  8. The product is developed quickly and provided regularly within a few weeks rather than a month.
Disadvantages of Agile Methodology
  1. There isn’t enough focus on the necessary design and documentation.
  2. The agile development process has a somewhat higher cost than traditional development methodologies.
  3. It isn’t appropriate for small-scale development projects.
  4. It is necessary for a project expert to make critical judgments during the meeting.
  5. If the project manager is unclear about the requirements and the outcome he or she desires, the project might easily go off track.
  6. Maintenance of the completed project can become challenging due to a lack of sufficient documentation once the project is completed and the developers are assigned to another project.

In this article, we have discussed the agile methodology in detail. The above-mentioned sections talk about its pros and cons, what was the need for Agile in software engineering. In order to avoid the last-minute hassle, this model was introduced and made the life of developers and testers easy. Moreover, this model is entirely focused on customer satisfaction as it involves frequent releases and client reviews at each release instead of one release on a long-term basis that has given a boom to the software industry in maintaining the software quality.
