Agile Software Development Methodology

A.

For your exam you should know below information about agile development: Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams.

It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.

It is a conceptual framework that promotes foreseen tight iterations throughout the development cycle.

Agile Development -

The Agile Manifesto introduced the term in 2001

Since then, the Agile Movement, with all its values, principles, methods, practices, tools, champions and practitioners, philosophies and cultures, has significantly changed the landscape of the modern software engineering and commercial software development in the Internet era.

Agile principles - The Agile Manifesto is based on twelve principles: Customer satisfaction by rapid delivery of useful software Welcome changing requirements, even late in development Working software is delivered frequently (weeks rather than months) Close, daily cooperation between business people and developers Projects are built around motivated individuals, who should be trusted Face-to-face conversation is the best form of communication (co-location) Working software is the principal measure of progress Sustainable development, able to maintain a constant pace Continuous attention to technical excellence and good design Simplicity"the art of maximizing the amount of work not done"is essential Self-organizing teams - Regular adaptation to changing circumstances What is Scrum? Scrum is the most popular way of introducing Agility due to its simplicity and flexibility.

Because of this popularity, many organizations claim to be doing Scrum but aren't doing anything close to Scrum's actual definition.

Scrum emphasizes empirical feedback, team self-management, and striving to build properly tested product increments within short iterations.

Doing Scrum as it's actually defined usually comes into conflict with existing habits at established non-Agile organizations.

The following were incorrect answers: Software prototyping- Software prototyping, refers to the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed.

It is an activity that can occur in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.

Rapid application development (RAD) is a software development methodology that uses minimal planning in favor of rapid prototyping.

The "planning" of software developed using RAD is interleaved with writing the software itself.

The lack of extensive per-planning generally allows software to be written much faster, and makes it easier to change requirements.

Component Based Development - It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems.

This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software.

The software development method that is based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams is Agile Development.

Agile Development is a flexible and iterative approach to software development that emphasizes the importance of delivering working software in small increments, rather than attempting to deliver a complete product all at once. Agile Development is based on the Agile Manifesto, a set of values and principles for software development that prioritize customer satisfaction, working software, and collaboration between developers and customers.

Agile Development is typically characterized by a series of short, time-boxed iterations, called sprints, during which a cross-functional team works together to complete a small, defined piece of functionality. The team collaborates closely with the product owner or customer to define and refine requirements throughout the development process, and incorporates feedback from stakeholders to improve the product over time.

Self-organizing teams are a key aspect of Agile Development, as they allow for a high degree of flexibility and adaptability in response to changing requirements and circumstances. Cross-functional teams are also important, as they allow for a wide range of perspectives and skill sets to be brought to bear on the development process.

In summary, Agile Development is a software development method based on iterative and incremental development, collaboration between self-organizing, cross-functional teams, and a focus on delivering working software in small increments.
