This document discusses Agile development and eXtreme Programming (XP). It describes XP as an Agile methodology that focuses on frequent delivery of working software through practices like test-driven development, pair programming, and continuous integration. The document outlines the 12 key practices of XP like planning games, simple design, refactoring, and on-site customers. It notes advantages of XP like increased customer focus and quality, and disadvantages like potential issues with certain team members or inflexible requirements.
This slide share will help users to understand the agile software development methodology and how does it work. It also defines the whole process to implement scrum methodology.
Agile software development is a group of software development methods in which requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.
The Agile development model is also a type of Incremental model. Software is developed in incremental, rapid cycles. This results in small incremental releases with each release building on previous functionality. Each release is thoroughly tested to ensure software quality is maintained. It is used for time critical applications.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

9. • Extreme programming (XP) is a software development
methodology which is intended to improve software
quality and responsiveness to changing customer
requirements.
• As a type of agile software development, it advocates
frequent "releases" in short development cycles.
• this way is intended to improve productivity and
introduce checkpoints at which new customer
requirements can be adopted.

11. The 12 Key Practices
• The Planning Game
• Small Releases
• Metaphor
• Simple Design
• Test-Driven Development
• Refactoring
• Pair Programming
• Collective Ownership
• Continuous Integration
• 40-Hour Workweek
• On-site Customer
• Coding Standards
11/34
12. 1. The Planning Game
• Requirements via User Stories
• Short cards with natural language description of
what a customer wants
• Prioritized by customer
• Resource and risk estimated by developers
• Play the Planning Game after each increment
12/34
14. 2. Metaphor
• Guide all development and conversations with a
simple shared story of how the whole system works
• Gives the team a whole picture of describing the
system, where new parts fit, etc.
• Words used to identify technical entities should be
chosen from the metaphor
• The default metaphor is the business domain, and it’s
usually just fine
14/34
15. 3. Testing
• Test-Driven Development (TDD)
• Write tests before code
• Tests are automated
• Acceptance Tests
• Written with the customer
• Acts as “contract”
• Measure of progress
15/34
16. Test-Driven Development
• Developers write unit tests before coding
• Motivates coding
• Improves design: cohesion and coupling
• Provides regression tests
• Provides specification by example
public void TestMultiplication() {
Dollar five = Money.dollar(5);
AssertEqual(new Dollar(10), five.times(2));
AssertEqual(new Dollar(15), five.times(3));
}
16/34
17. 4. Pair Programming
• Two software engineers work on one task at one
computer:
• The driver has control of the keyboard and mouse and
creates the implementation
• The navigator watches the driver’s implementation
• Identifies defects and participates in on-demand
brainstorming
• The roles of driver and observer are periodically rotated
17/34
18. Pair Programming
• Pairs produce higher quality code
• Pairs complete their tasks faster
• Pairs enjoy their work more
• Pairs feel more confident in their work
18/34
19. 5. Refactoring
• Improve the design of existing code without changing
its functionality
• Relies on unit testing to ensure the code is not broken
• Bad smells in code:
• Long method / class
• Duplicate code
• Methods does several different things (bad cohesion)
• Too much dependencies (bad coupling)
• Complex / unreadable code
19/34
20. 6. Simple Design
• No Big Design Up Front (BDUF)
• Reduces the overhead
• Gets feedback early
• “Do The Simplest Thing That Could Possibly Work”
• Later use refactoring to change it
• Not too much formal documentation
20/34
21. 7. Collective Code Ownership
• Code to belongs to the project, not to an individual
engineer!
• Any engineer can modify any code
• Better quality of the code
• Engineers are not required to work around
deficiencies in code they do not own
• Faster progress
• No need to wait for someone else to fix something
21/34
22. 8. Continuous Integration
• Pair writes up unit test cases and code for a task (part
of a user story)
• Pair unit tests code to 100%
• Pair integrates
• Pair runs ALL unit test cases to 100%
• Pair moves on to next task with clean slate and clear
mind
• Should happen once or twice a day
22/34
23. 9. On-Site Customer
• Customer available on site
• Clarify user stories
• Make critical business decisions
• Developers don’t make assumptions
• Developers don’t have to wait for decisions
• Face to face communication minimizes the chances of
misunderstanding
23/34
24. 10. Small Releases
• As small as possible, but still delivering business value
• No releases to ‘implement the database’
• Get customer feedback early and often
• Do the planning game after each iteration
• Do they want something different?
• Have their priorities changed?
24/34
25. 11. Forty-Hour Work Week
• Kent Beck says, “ . . . fresh and eager every morning,
and tired and satisfied every night”
• Burning the midnight oil kills performance
• Tired developers make more mistakes
• Slows you down more in the long run
25/34
26. 12. Coding Standards
• Use coding conventions
• Rules for naming, formatting, etc.
• Write readable and maintainable code
• Method commenting
• Self-documenting code
• Don't comment bad code, rewrite it!
• Refactor to improve the design
26/34
27. The 13th Practice?
The Stand Up Meeting
• Start the day with 15-minute meeting
• Everyone stands up (so the meeting stays short) in
circle
• Going around the room everyone says specifically:
• What they did the day before
• What they plan to do today
• Any obstacles they are experiencing
• Can be the way pairs are formed
27/34

People Communicate Most Effectively Face-to-Face
28/34
29. So What does XP Apply to?
• Domains with changing requirements
• High-risk projects (including those with high schedule
risk)
• Small project team: 2 – 12 programmers
• Cannot be used with a large team
• Extended development team
• Developers, managers and customer
• Co-located
• Automated testability
29/34
30. Advantages
• Customer focus increase the chance that the software
produced will actually meet the needs of the users
• The focus on small, incremental release decreases the risk
on your project:
• by showing that your approach works and
• by putting functionality in the hands of your users, enabling them to
provide timely feedback regarding your work.
• Continuous testing and integration helps to increase the
quality of your work
• XP is attractive to programmers who normally are unwilling
to adopt a software process, enabling your organization to
manage its software efforts better.
30/34
31. Disadvantages
• XP is geared toward a single project, developed and maintained by
a single team.
• XP is particularly vulnerable to "bad apple" developers who:
• don't work well with others
• who think they know it all, and/or
• who are not willing to share their "superior” code
• XP will not work in an environment where a customer or manager
insists on a complete specification or design before they begin
programming.
• XP will not work in an environment where programmers are
separated geographically.
31/34
32. Conclusion
• XP focuses on people
• Values team work over power
• XP works well when there are
uncertain or volatile requirements
• XP is a process not a miracle cure for
all software development problems
