What about Agile Methodologies? Is Agile (SCRUM) still popular in big software projects? Do we still have to implement bicycle with new name for software development process? I think nope, because we are uncovering better ways of developing
software by doing it and helping others do it Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more.
We follow these principles:
Our highest priority is to satisfy the customer
through early and continuous delivery
of valuable software.
Welcome changing requirements, even late in
development. Agile processes harness change for
the customer's competitive advantage.
Deliver working software frequently, from a
couple of weeks to a couple of months, with a
preference to the shorter timescale.
Business people and developers must work
together daily throughout the project.
Build projects around motivated individuals.
Give them the environment and support they need,
and trust them to get the job done.
The most efficient and effective method of
conveying information to and within a development
team is face-to-face conversation.
Working software is the primary measure of progress.
Agile processes promote sustainable development.
The sponsors, developers, and users should be able
to maintain a constant pace indefinitely.
Continuous attention to technical excellence
and good design enhances agility.
Simplicity--the art of maximizing the amount
of work not done--is essential.
The best architectures, requirements, and designs
emerge from self-organizing teams.
At regular intervals, the team reflects on how
to become more effective, then tunes and adjusts
its behavior accordingly.
Core Values:
The Agile Manifesto emphasizes four main values:
-
Individuals and interactions over processes and tools: While recognizing the value of the latter, the manifesto values the former more. This highlights the importance of teamwork, collaboration, and the ability to adapt to changes.
-
Working software over comprehensive documentation: While documentation has its place, the manifesto values software that works and meets the customer's needs more highly.
-
Customer collaboration over contract negotiation: Engaging with the customer throughout the development process is valued more than negotiating the terms of the product delivery.
-
Responding to change over following a plan: The ability to adapt to changes even late in the development process is considered more important than strictly adhering to a pre-defined plan.
12 Principles:
The Agile Manifesto is also supported by 12 principles which further describe the approach to software development:
- Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
- Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
- Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
- Business people and developers must work together daily throughout the project.
- Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
- The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
- Working software is the primary measure of progress.
- Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
- Continuous attention to technical excellence and good design enhances agility.
- Simplicity—the art of maximizing the amount of work not done—is essential.
- The best architectures, requirements, and designs emerge from self-organizing teams.
- At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
These values and principles guide the Agile approach to software development, emphasizing flexibility, collaboration, and customer satisfaction. They underpin various Agile methodologies, such as Scrum, Kanban, and Extreme Programming (XP).
