Agile Software Development Methodology is a process of software development (such as other software development methodologies – waterfall model, V-model, iterative model, etc.), however, the Agile development model is also a type of incremental model. Software develops in incremental, rapid cycles.

In English, Agile means ‘the ability to move quickly and easily’ and respond to change rapidly – this is an important aspect of Agile software development.

Advantages of Agile Methodology

  1. Focus on Customer Value: Agile places a high priority on providing customers with value by attending to their requirements and preferences. Agile guarantees that the most important features are produced first and that iterative changes are driven by customer feedback by dividing work down into small, manageable tasks.
  2. Enhanced Team Morale and Motivation: Agile gives teams the freedom to own their work and decide together. Team members feel motivated, proud, and owned when they have this autonomy together with a focus on providing value and ongoing growth.
  3. Stakeholder Collaboration: Throughout the development process, agile promotes strong coordination between product owners, developers, and other stakeholders. Better communication, a common understanding of the objectives, and ongoing feedback are all fostered by this partnership, which produces results that are higher quality and boost stakeholder satisfaction.
  4. Early and Continuous Delivery: Agile encourages the tiny, incremental releases of functional software. This gives early access to observable progress and facilitates early input and validation for stakeholders. Continuous delivery reduces risks by spotting problems early on and taking action to fix them.
  5. Delivering high-quality software: It is a key component of agile development, and this is emphasized by techniques like continuous integration, automated testing, and frequent inspection and modification. Agile guarantees that the software satisfies the required standards and lowers the likelihood of faults by integrating quality assurance throughout the development process.

Disadvantages of the Agile Methodology

  1. Lack of Predictability: Project timeframes and outcomes might be difficult to predict with accuracy due to Agile iterative and incremental methodology. Stakeholders who need set budgets or timeframes may find this unpredictability troublesome.
  2. Dependency on Customer Availability: Agile greatly depends on ongoing customer and stakeholder feedback and participation. Customers who are unavailable or who don’t know enough about the domain can impede development and slow it down.
  3. Scaling Agile: While Agile works effectively for small to medium-sized teams working on relatively basic projects, scaling Agile methods to bigger teams or more complicated projects can be more difficult. As the project grows, it gets harder to maintain coordination, alignment, and communication.
  4. Dependency on Team Dynamics: Agile’s focus on self-organizing, cross-functional teams with the authority to reach decisions together is paramount. Inadequate communication within the team or a lack of experience or expertise among team members can negatively affect output quality and productivity.
  5. Increased Overhead: Planning, coordinating, and communicating take more time and effort when using agile frameworks like Scrum. This overhead can take a lot of time, especially for projects with short deadlines or small teams.
