0:16
learning today we're talking about
0:18
Extreme Programming or XP an agile
0:21
framework that helps teams produce
0:23
highquality software quickly while
0:26
embracing change and improving
0:28
collaboration if you're managing
0:30
software development projects XP could
0:34
gamecher extreme programming is a
0:36
software development methodology focused
0:38
on customer satisfaction adaptability
0:41
and highquality code it emphasizes
0:44
continuous delivery of small functional
0:47
parts of a project and promotes constant
0:49
feedback from customers and team members
0:51
the goal is to stay flexible improving
0:54
the process as you go
0:56
before we get into the nitty-gritty
0:58
practices let's cover the five core
1:02
XP these values are the foundation for
1:05
how teams operate in an XP
1:11
communication xp fosters open and
1:14
constant communication among team
1:16
members customers and stakeholders
1:18
whether it's through pair programming or
1:20
daily standups communication helps keep
1:22
everyone aligned and reduces
1:28
simplicity xp encourages simplicity in
1:31
both design and decision making you
1:34
focus on solving only the immediate
1:36
problems and avoid over complicating the
1:39
system with unnecessary features the
1:42
idea is to keep things simple efficient
1:44
and easy to adapt later on three
1:48
feedback continuous feedback is a
1:51
critical part of XP from running
1:53
automated tests to gathering customer
1:56
input feedback ensures that the team is
1:58
always moving in the right direction and
2:00
that any issues are addressed
2:05
courage xp teams are encouraged to make
2:08
bold decisions like refactoring code or
2:11
revisiting design choices when needed
2:14
courage also means being honest when
2:16
things aren't working and embracing
2:17
change even when it's
2:19
challenging five respect
2:23
respect underpins everything in
2:25
XP every team member regardless of their
2:28
role is valued and respected for their
2:30
contributions this culture of respect
2:32
helps create a collaborative supportive
2:34
environment where ideas are freely
2:36
shared now let's talk about the 12
2:39
practices that make XP work in real life
2:42
projects these practices provide a
2:44
framework for how the team collaborates
2:46
writes code and delivers software
2:50
one the planning game in XP planning is
2:54
divided into two parts release planning
2:57
planning release planning the customer
3:01
and team prioritize the user stories or
3:04
requirements that should be included in
3:06
the next release this helps set clear
3:08
goals and expectations for the
3:10
project iteration planning the team
3:14
plans the work for the upcoming
3:15
iteration usually lasting one to two
3:18
weeks focusing on delivering the highest
3:25
releases rather than waiting months for
3:28
a big release the XP team aims to
3:30
release small functional chunks of the
3:33
software frequently this helps ensure
3:35
that the customer gets value early and
3:37
can provide feedback on each
3:41
metaphor in XP a metaphor is a shared
3:45
simple story that describes how the
3:47
system works think of it as a mental
3:49
model that guides everyone on the team
3:52
it's not a detailed design but a
3:54
high-level idea that helps developers
3:56
understand how the system fits
4:01
design xp advocates for the simplest
4:04
design that works the goal is to build
4:07
only what's necessary right now avoiding
4:10
overengineering this way the system can
4:12
evolve as the requirements change or
4:18
development xp relies heavily on
4:21
test-driven development TDD which means
4:24
writing tests before writing the code
4:26
developers write unit tests that define
4:28
the behavior of the software and then
4:31
write code to pass those tests this
4:33
ensures the code is reliable and
4:35
bug-free from the start six
4:38
refactoring refactoring means
4:40
continuously improving the code without
4:43
changing its behavior in XP developers
4:46
refactor code to simplify it improve
4:48
performance or remove redundancy this
4:51
keeps the code clean and maintainable
4:56
programming in pair programming two
4:59
developers work together at the same
5:01
workstation one writes the code while
5:03
the other reviews it in real time this
5:06
practice not only improves the quality
5:08
of the code but also enhances
5:09
collaboration and knowledge sharing
5:12
eight collective code
5:15
ownership with XP collective code
5:18
ownership means that any developer can
5:20
modify any part of the code at any time
5:22
there's no single person who owns a
5:24
specific part of the code base so the
5:27
entire team shares responsibility for
5:29
the project this encourages
5:31
collaboration and prevents
5:33
bottlenecks nine continuous integration
5:37
in XP teams integrate their code
5:40
frequently usually multiple times a day
5:43
with continuous integration every time a
5:46
developer commits new code it's
5:48
automatically tested and merged into the
5:51
main code base this helps catch
5:53
integration problems early and ensures
5:55
that the system is always in a working
5:58
state 10 40hour work week xp encourages
6:03
a sustainable pace for developers the
6:06
40-hour work week practice means that
6:09
developers should maintain a reasonable
6:11
work life balance and avoid burnout
6:13
overtime is allowed in emergencies but
6:15
it should never become the
6:19
11 on-site customer an on-site customer
6:23
is an actual customer or a
6:24
representative who works closely with
6:26
the team this person provides immediate
6:29
feedback clarifies requirements and
6:31
helps set priorities having direct
6:33
access to the customer helps the team
6:35
make better decisions and ensures the
6:38
project stays aligned with customer
6:43
standards finally XP teams follow
6:46
consistent coding standards to ensure
6:48
that the code is clean readable and
6:50
maintainable by adhering to a common set
6:53
of coding practices the team can
6:55
collaborate more effectively and avoid
6:58
issues that come from inconsistent code
7:01
so why use extreme programming it's
7:04
particularly useful in environments
7:06
where requirements are likely to change
7:08
or where the team needs to deliver
7:10
highquality software under tight
7:12
deadlines the frequent feedback loops
7:15
and small releases allow for quick
7:17
course corrections and practices like
7:19
pair programming and test-driven
7:21
development ensure high code quality
7:24
xp also helps build a strong
7:26
collaborative culture where everyone is
7:28
responsible for the project's success
7:31
plus the focus on sustainable work
7:33
practices like the 40-hour work week
7:35
promotes a healthy work life
7:37
balance that said XP isn't without its
7:41
challenges practices like pair
7:43
programming or having an on-site
7:45
customer can be difficult to implement
7:48
in some teams or organizations
7:51
it also requires a high level of
7:53
discipline to maintain practices like
7:55
TDD and continuous integration however
7:58
when implemented well XP can
8:00
significantly improve both the quality
8:02
of the software and the working
8:06
