The document provides an overview of agile software development, highlighting its focus on flexibility, collaboration, and customer satisfaction based on the agile manifesto. It outlines the agile development process, including stages from requirements gathering to maintenance, and describes various models like scrum and extreme programming. Additionally, it discusses the advantages and disadvantages of agile development, emphasizing faster time-to-market and improved customer satisfaction alongside challenges such as lack of planning and difficulty in estimating effort.

2. Agile Development
 Agile Software Development is a software
development methodology that values flexibility,
collaboration, and customer satisfaction.
 It is based on the Agile Manifesto, a set of
principles for software development that prioritize
individuals and interactions, working software,
customer collaboration, and responding to
change.
 Agile Software Development is an iterative and
incremental approach to software
development that emphasizes the importance of
delivering a working product quickly and
frequently.
 It involves close collaboration between the
development team and the customer to ensure
that the product meets their needs and
expectations.

3. Agile Software Development
Process
 Requirements Gathering: The customer’s
requirements for the software are gathered and
prioritized.
 Planning: The development team creates a plan for
delivering the software, including the features that will
be delivered in each iteration.
 Development: The development team works to build
the software, using frequent and rapid iterations.
 Testing: The software is thoroughly tested to ensure
that it meets the customer’s requirements and is of high
quality.
 Deployment: The software is deployed and put into
use.
 Maintenance: The software is maintained to ensure
that it continues to meet the customer’s needs and
expectations.

5. Agile Process Models
 Extreme Programming (XP)
 Dynamic Systems Development
Method (DSDM)
 Scrum
 Crystal
 Feature Driven Development (FDD)
 Lean Software Development

6. Extreme Programming(XP)
 Relies on object-oriented approach
 Key activities
◦ Planning (user stories created and ordered by
customer value)
◦ Design (simple designs preferred, CRC cards and
design prototypes are only work products,
encourages use of refactoring)
◦ Coding (focuses on unit tests to exercise stories,
emphasizes use of pairs programming to create story
code, continuous integration and smoke testing is
utilized)
◦ Testing (unit tests created before coding are
implemented using an automated testing framework
to encourage use of regression testing, integration
and validation testing done on daily basis,
acceptance tests focus on system features and
functions viewable by the customer)

7. Adaptive Software
Development
 Self-organization arises when independent agents cooperate to create
a solution to a problem that is beyond the capability of any individual
agent
 Emphasizes self-organizing teams, interpersonal collaboration, and
both individual and team learning
 Adaptive cycle characteristics
 Phases
◦ Mission-driven
◦ Component-based
◦ Iterative
◦ Time-boxed
◦ Risk driven and change-tolerant
◦ Speculation
◦ Collaboration
◦ Learning

8. Scrum
 SCRUM is an agile development process
focused primarily on ways to manage tasks in
team-based development conditions.
 There are three roles in it, and their
responsibilities are:
 Scrum Master: The scrum can set up the master
team, arrange the meeting and remove obstacles
for the process
 Product owner: The product owner makes the
product backlog, prioritizes the delay and is
responsible for the distribution of functionality on
each repetition.
 Scrum Team: The team manages its work and
organizes the work to complete the sprint or
cycle.

9. Crystal
 There are three concepts of this method-
 Chartering: Multi activities are involved in
this phase such as making a
development team, performing feasibility
analysis, developing plans, etc.
 Cyclic delivery: under this, two more
cycles consist, these are:
◦ Team updates the release plan.
◦ Integrated product delivers to the users.
 Wrap up: According to the user
environment, this phase performs
deployment, post-deployment.

10. Advantages of Agile
Development
 Faster Time-to-Market
 Improved Customer Satisfaction.
 Increased Flexibility
 Better Quality
 Improved Team Collaboration
 Reduced Risk
 Increased Employee Engagement
 Improved Adaptability

11. Disadvantages of Agile
Development
 Lack of Planning
 Difficulty in Estimating Effort
 Limited Scalability
 Difficulty in Managing Complexity
 Lack of Documentation
 Resistance to Change
 Difficulty in Measuring Progress
