What is Agile?

Agile means something, which is able to run or move easily. 

Agile refers to development based on an iterative approach. It was born out of the agile manifesto

In an agile model, tasks are divided into smaller iterations or parts that only require short-term goals. It is essential that the project strategies and needs are established before the development process begins.

The required number of iterations, lengths, and strategies of each iteration is planned well in advance.

An iteration is considered as a short timeframe in the Agile model, which typically lasts from two to four weeks.

Division of the project into brief parts helps considerably reduce the risks involved and minimizes the time requirements for project delivery.

Each iteration may involve a team working through a full development life cycle including planning, requirements, and so on.

Advantages of the Agile model

  • Increased Product Quality
    In an Agile development model, testing is required throughout every stage of project development.
    This ensures that the product designed at the end is of high quality and strictly according to the demands of the consumer.
    Testing at every stage allows space for any amends in a product and also enables the developers to catch any bugs present before they become a big deal.
  • Flexibility
    One of the most praised features of agile is the flexibility it brings to a project.
    Because the methodology allows for change, there is always room for mistakes and opportunities to iterate.
  • Faster Product Delivery
    A major part of the Agile model is Sprints. 
    Sprints are a set period of time that allows a product to be developed frequently and rapidly. 
    In today’s market, speed is the key! Following the agile methodology helps deliver products to the users faster, allowing for speedy testing and fixing of software solutions, and reducing time to market.
  • Improved Team morale
    Since Agile teams are mostly self-organized and self-managing, they have increased authority over their decisions. 
    It is considered the job of the project manager to shield the team from interference from the outside management.
    Due to the cross-functional nature of the teams, the members can learn new skills as well as grow in their current domains.
    The team size is generally limited in an Agile environment and meets frequently to discuss the progress and update the other members about the current status of the project. This also provides a workplace where teams can be close-knit and have flexible team structures.
  • Reduced Risks
    An agile development team divides a bigger project into small tasks. 
    Working on these small tasks helps the team to identify any problems with the project early reducing the risks and making it easier to perform any changes if needed.

FAQs

Q: What are examples of the Agile model?

A: Scrum, eXtreme Programming (XP), Feature Driven Development (FDD), Dynamic Systems Development Method (DSDM), Adaptive Software Development (ASD), Crystal, and Lean Software Development (LSD) are some examples of Agile model.

Q: What is the difference between agile and waterfall methodologies?

A: Waterfall methodology adopts breaking the project into linear steps where each step is dependent on the previous step, whereas agile methodology is an incremental and iterative process with short-term goals.
