What Is XP
XP, or Extreme Programming, is a lightweight software development method based on principles of communication, feedback, simplicity, and courage. It is designed for small teams developing quality software quickly in an environment of changing requirements. Key concepts include short iteration cycles, retrospectives, test-driven development, collective code ownership, on-site customers, and frequent small releases. The core practices are on-site customers, planning games, small releases, simple design, testing, refactoring, pair programming, and collective ownership. XP aims to address issues like business misunderstandings, changing requirements, schedule delays, adding unnecessary features, and misaligned priorities between business and development.

Bogdan molocea scaling up using automation and performance testing
The document discusses scaling systems to handle elastic demand through horizontal and vertical scaling, as well as scaling software, hardware, and services. It describes challenges faced with poor performance, unpredictability, and crashes when scaling up. Solutions involved using Scala, AngularJS, a new automation framework with Apache JMeter, and performance testing tools. Through iterations of performance testing and improvements, the system performance improved from three times slower than baseline to seven times faster than baseline. The key lessons are to use automation testing early to identify issues, write performant code, and leverage tools to deliver scalable systems.

Overview of extreme programming
Extreme Programming의 개요에 대해 설명한 문서입니다.
여기 나와있는 그림은 (넘기고) 이 책의 2장의 첫번째 페이지에서 나오는 그림인데요,
저는 처음 이 그림의 밑에 나와있는 설명을 보고 무슨 말인지 전혀 이해하지 못했습니다.
한국어로 직역하면, 개발자로서 우리는 extreme programmin이 마을의 유일한 게임이 아님을 기억해야한다, 입니다. 이게 도대체 무슨 말인가 싶어서 검색해보았더니/only game in town은 일종의 관용어구로 유일한 선택지나 최선의 선택지라는 뜻이 있었습니다. 즉, 개발자로서 우리는 extreme programming이 유일한 선택지가 아니라는 것을 기억해야한다는 말이죠. 이게 무슨 말인지 이제부터 알아보겠습니다./위키에 의하면, Extreme Programming은 계속해서 변화하는 고객의 요구사항에도 높은 퀄러티의 소프트웨어를 개발하고, 개발 팀의 삶의 질을 보장하는데 목적이 있는 애자일 소프트웨어 개발 프레임워크입니다. /Extreme Programming은 소프트웨어 요구사항이 동적으로 변화하는 경우,
새로운 기술로 마감 시한이 정해져있는 프로젝트를 하는 경우,
소규모의 공동으로 개발하는 팀의 경우 등의 상황에서 사용하기 적합한 방법입니다.
아까 Introduction에서 말씀드렸던 것 처럼 XP가 모든 상황에서 적합한 방법은 아닙니다.
이 페이지의 두번째 링크를 보면, XP가 언제 적합하지 않은지 나와있으니 궁금하신 분은 후에 확인하셔도 좋을 것 같습니다.
/Extreme Programming은 팀워크를 강조하는데요,
Extreme Programming이 소프트웨어의 퀄러티를 개선시키는데는 다섯가지의 방법이 있습니다. 의사소통과 단순성, 피드백, 존중 그리고 용기입니다. 일종의 핵심 가치라고도 할 수 있습니다.
/Extreme Programming의 핵심가치를 하나씩 설명해보겠습니다.
첫번째로 커뮤니케이션, 소프트웨어 개발은 본질적으로 축구나 야구와 같은 팀 스포츠와 같다고 볼 수 있습니다. 우리는 충분한 의사소통을 통해, 팀 구성원 한명 한명이 다른 팀 구성원들에게 지식을 전달해야합니다. 의사소통이 제대로 되지 않는 팀은 쉽게 어긋나고 말죠.
두번째로 단순성은 우리가 할 수 있는, 알고 있는 요구사항만을 다루는 것을 의미합니다. 고객이 어떤 것을 요구할 것 같다는, 미래를 예측하는 행동을 하지 않는 것입니다. 이는 낭비를 가능한 한 피하고, 가능한한 시스템설계를 단순하게 유지하는 등 절대적으로 필요한 일만을 하는 것입니다.
세번째로 피드백은, 팀원 각자들이 해온 노력들을 꾸준히 피드백을 함으로써 어떤 분야를 더 개선해야 할지 발견할 수 있게 하는 것입니다.
마지막으로 용기와 존중입니다. Extreme Programming에서 Extreme은 한국어로 하면 ‘극단적인＇이라는 의미를 가지고 있습니다. 팀의 효율성을 저하시키는 조직의 문제를 제기하려면 용기가 필요합니다. 또한 작동하지 않는 것을 개발하는 것을 멈추고 다른 것을 시도하는 것 또한 용기를 필요로 합니다. 수락하기 어려운 경우에도 피드백을 수락하고 그를 행동으로 옮기는 데도 용기를 필요로 합니다.
팀원들은 서로 의사소통을 하고 피드백을 제공하고 수락하며 협력하기 위해 서로를 존중해야 합니다.
/(Practice : 관행)
이 페이지에 나와있는 12가지의 리스트는 소프트웨어 개발 관행입니다.
전부 다 소개하기에는 너무 많은 것 같아서 우리에게 익숙한 Refactoring에 대한 상세 설명만 준비했습니다. 나머지 관행들에 대해서는 책을 읽으시면 자세한 설명을 찾을 수 있습니다.
/(Practice : 관행)
아마 대부분의 분들이 많이 들어봤을 단어인데요,
코드를 작성하고나면 종종 내가 왜 이런식으로 코드를 짰지? 하고 당황할정도로 엉망진창인 코드를 발견하게 되기도 합니다.
extreme programming은 잦은 리팩토링을 통해 코드를 최대한 깨끗하고 단순하게 유지합니다.
리팩토링이란 시스템의, 프로그램의 동작에는 영향을 주지 않으면서 프로그램의 구조에는 변화를 주는 개선 방식입니다. 각각의 변화는 사소한 것이며, 우리는 리팩토링을 완료한 후에 우리가 어떤 동작에 영향을 주지 않았는지 확인을 하기 위해 유닛 테스트를 진행합니다.
리팩토링은 개발도중 지속적으로 진행되며, 이를 통해 아까 언급했던 것처럼 코드를 최대한 깨끗하고 단순하게 유지할 수 있습니다.
/마지막으로 결론입니다.
extreme programming은 앞에서 소개한 다섯가지의 가치를 기반으로한 소프트웨어 개발 방법론입니다. 이 가치들은 팀을 하나로 묶어주며, 서로에게 충분한 피드백을 함으로써 현재 팀원 자신의 위치를 직시하게 하고, 관행들을 고유한 상황에 맞게 조율할 수 있도록 합니다.
프로젝트를 진행하는 대부분의 팀들이 XP를 그대로 사용할 수 있지만, 몇몇 팀들은 관행을 추가하거나 수정함으로써 적용시킬 수 있습니다.

Chap 3 - Agile - XP.ppt
Extreme Programming (XP) is an agile software development framework that focuses on customer satisfaction, rapid and flexible response to change, simplicity, communication, and feedback. The core practices of XP include the planning game, simple design, metaphor, continuous testing, pair programming, collective code ownership, and continuous integration. Tests are written and automated before code is written to ensure customer requirements are met. Customers are involved throughout development providing feedback and acceptance tests. Frequent small releases are made, often multiple times per day, to get working software into customers' hands quickly.
Lecture 7 agile software development (2)
This document provides an overview of agile software development using Extreme Programming (XP). It discusses the key activities in XP: planning, design, coding, and testing. In the planning activity, user stories are written and prioritized by the customer. Design focuses on implementing user stories through class-responsibility-collaborator cards and spike solutions. Coding is done in pairs and integrated daily. Testing involves unit tests written for each user story before coding as well as acceptance tests specified by the customer. The goal of XP is to deliver high quality working software frequently through these iterative activities.

Methodologies, frameworks, and processes Part 5
Kanban is a lean production method derived from Toyota's production system. It utilizes a Kanban board to visualize the workflow and limit work-in-progress through different stages shown as columns. The five key principles of Kanban are to visualize workflow, limit work-in-progress, manage flow, make policies explicit, and improve collaboratively. Kanban employs a pull system where completing an item triggers pulling the next work item and uses work-in-progress limits on columns.
Methodologies, frameworks, and processes Part 4
Lean product development originated from the Toyota Production System and focuses on eliminating waste to optimize the production process and deliver value fast. Some key concepts of lean include eliminating waste, empowering teams, optimizing the whole system, building in quality, and deferring decisions to amplify learning. The seven wastes lean production seeks to reduce are partially done work, extra processes, extra features, task switching, waiting, motion, and defects.
Methodologies, frameworks, and processes Part 2
Scrum is a popular lightweight agile framework that is easy to understand. It is documented in the Scrum Guide and based on principles of transparency, inspection, and adaptation. The Scrum team consists of a Product Owner, Scrum Master, and team of 5-9 members. The Product Owner is responsible for goals and priorities while the Scrum Master removes impediments. The team self-organizes during sprints which include planning, daily stand-ups, review and retrospective meetings. Key activities focus on backlog refinement, sprint planning, daily scrums and sprint reviews and retrospectives.
Methodologies, frameworks, and processes Part 1
This document introduces several agile methodologies, frameworks, and processes that share the core philosophy outlined in the Agile Manifesto. It lists lightweight approaches like Scrum and Kanban as well as more full-featured approaches. The document notes that teams may combine elements from different agile approaches, using techniques like planning sprints from Scrum together with simple design practices from Extreme Programming.
Life cycle selection
Agile is a dynamic project life cycle approach that focuses on frequent delivery of customer value through iterative development and feedback. It is characterized by repeated cycles of analysis, design, implementation, and testing until the project is complete. This allows for changes to requirements throughout development. In contrast, predictive life cycles like the waterfall model use a fixed sequential approach and aim to manage costs, while iterative life cycles focus on correctness and incremental life cycles emphasize frequent smaller deliveries with speed.
Uncertainty, risk, and life cycle selection
Projects with high uncertainty around requirements and technology have greater risks of rework. As uncertainty increases, so does risk. To mitigate these risks, teams select iterative life cycles that allow work to be done in small increments. Approaches using very short feedback loops and frequent adaptation, reprioritization, and delivery help teams adapt more easily to changes under conditions of high uncertainty and complexity.
Agile mindset
Agile focuses on developing an "Agile mindset" or way of thinking as the foundation for successfully implementing Agile practices. The Agile mindset is defined by the four values and twelve principles of the Agile Manifesto. It is a mindset that values individuals and interactions, working software, customer collaboration, and responding to change. This mindset is then manifested through selecting appropriate Agile practices and processes based on a team or organization's specific needs, tailoring them as necessary. True Agility comes from internalizing this mindset in order to flexibly apply practices, not from just following specific methodologies.
Agile Manifesto - Principles - Part 1
The document outlines the 12 principles of the Agile Manifesto which provide guidance for agile methods. It discusses each principle individually. The principles focus on satisfying customers, welcoming changing requirements, frequent delivery of working software, collaboration between business and developers, motivating individuals, face-to-face communication, using working software to measure progress, maintaining a sustainable pace, technical excellence and design, simplicity, self-organizing teams, and continuously improving.
Agile manifesto values
The document introduces the Agile Manifesto and its core values:
- Individuals and interactions over processes and tools, with a focus on collaboration between people rather than reliance on processes or tools.
- Working software over comprehensive documentation, with an emphasis on delivering working software of business value rather than extensive paperwork.
- Customer collaboration over contract negotiation, with flexibility to accommodate changing customer priorities rather than rigid adherence to contracts.
- Responding to change over following a plan, with efforts focused on adapting to inevitable changes rather than strict adherence to initial plans.
Agile manifesto
The document introduces the Agile Manifesto, which was created in 2001 by software experts in the forefront of emerging agile methods. It outlines four values and twelve principles for agile development. While the PMI-ACP exam won't ask about the origin or creators of Agile, it will focus on applying the values and principles of the Agile Manifesto to situational questions.
What and why using agile
This document provides an introduction to Agile and why it is used. It discusses that Agile allows teams to (1) learn with each new iteration, (2) deliver prototypes and improve them in each cycle, and (3) manage shifting priorities more effectively. It also differentiates between industrial work, which uses defined processes, and knowledge work, which relies on empirical processes better suited to uncertain projects. Agile provides a flexible approach for managing knowledge work.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
