XP was one of the first agile methods , indeed XP was the dominant agile method in the late 90s and early 00s before Scrum became dominant as the noughties passed. Many people including myself consider XP to be the primary catalyst that got attention to agile methods, and superior to Scrum as a base for starting out in agile development. Kent developed XP over the course of his consulting to Smalltalk projects in the late 80s and early 90s. The full set of practices that came to be known as XP were first used together in the C3 project where I worked with Kent and learned about it. The name "Extreme Programming" came later as the approach was described, first informally on the WikiWikiWeb and then later in a series of books. Various teams took the description in the WikiWikiWeb and implemented XP themselves, thus replicating the methodology and showing it could be used outside its original home.

kent beck extreme programming My impression apple iigs rom file that people used this word as a mixture of joke and truth to categorise XP. The beauty of this strategy is that it is always working ,ent the problem with the biggest impact, so everyone has motivation to make it kent beck extreme programming. That doesn't mean that you can't ever do interesting things on an XP project, but you would never try new technology for new technology's sake. In fact, that's what we're writing, we're just publishing it a little at a time, so we have the chance to get feedback from readers about what is most important to cover. Authors in the series went through various aspects attending XP and programming practices. Jan 09,  · Kent Beck, a pioneer of the Agile software development movement and author of Extreme Programming Explained. Below are excerpts from a fascinating Java Magazine interview with Beck, by Editor in Author: Chris Murphy. Extreme programming was created by Kent Beck during his work on the Chrysler Comprehensive Compensation System (C3) payroll project. Beck became the C3 project leader in March and began to refine the development methodology used in the project and wrote a book on the methodology (in October , Extreme Programming Explained was published). Oct 08,  · Extreme Programming (xp): A Gentle Introduction. The first Extreme Programming project was started March 6, Extreme Programming is one of several popular Agile luhost.xyz has already been proven to be very successful at many .

Extreme Programming is a humanistic discipline of software development, based on principles of simplicity, communication, feedback, and courage. XP was developed by Kent Beck. With the kind permission of SIGS that interview is reprinted here. At the OOP'99 in Munich your talk had the biggest audience and the most feedback. First, I'd like to know where the idea of XP comes from. Who are the people that "invented" XP? I am the one who put all the pieces together, and the one who coined the name.

However, the ideas in XP come from many sources. I'm lucky if an original thought happens through my head once in five years, so generally I have to make my living putting together ideas that other folks haven't thought to put together. So, for example:. The iteration schedule comes from Jon Hopkins in my opinion the most under-rated thinker in the world of objects. The strict separation of business decision making from technical decision making comes from the architect Christopher Alexander.

The idea of making change in small steps where you always keep the system running comes from my dad, Doug Beck, who wrote process control software in assembly language for 8 bit micro processors. However, looking on different Web Sites such as the Wiki page "Extreme Programming Roadmap" these aspects seem to be only a part of "practices" and "concepts" of XP.

Is this true? You can explain XP at many different levels of granularity. Teams will evolve hundreds of little rules over a couple of years. From meters, XP is about short cycles with concrete feedback. The list above is good for helping programmers understand basically how they will work.

It is also good for explaining how XP, which eschews many of the traditional forms of project control, can still be a stable, predictable, and reliable way to produce software. No one book can possibly cover them all, so I've chosen to publish an overview book as quickly as possible, then help the XP community follow up with more detailed books as we gain experience. However, some practices seem to be more important than others.

For example, testing seems to be a core aspects. If I understand it right, testing seems to be a requirement for successful refactoring, collective code ownership, and contiguous integration. So, which are the "core" aspects or practices of extreme programming? It's tough to say exactly. In a way it's like a spider's web. If you pick up one thread, the rest of them come, too. I always end up saying, "The one most important practice is testing.

Testing and refactoring. The two most important practices are testing and refactoring. And the Planning Game. Okay, the three most Certainly without the tests, you're dead. Fortunately, test-first-coding is also the practice that is most useful whatever project culture you have.

But, as I said, from there I quickly pull in the rest of the practices listed above. The most often short description of XP I heard from other people before and after the talk was "hacking".

My impression was that people used this word as a mixture of joke and truth to categorise XP. Could you explain why XP is not just "hacking" or where the difference is? There is a taboo against "programming before thinking". I think every programmer has programmed themselves into a corner at some point in their career, often very early in their career. So it becomes an insult to say that someone "jumps right into coding". And XP certainly advocates coding throughout the life of the project.

So I'm not surprised to hear people say that. One big difference between XP and "hacking" is that hacking to me implies that someone does only enough design to keep from stopping altogether, where XP has a strong culture of making things simpler whenever you see that they can be made simpler. The heartbeat of XP is the coding episode, which goes like this:.

A programming pair write the next automated test case for an engineering task. Writing the test case forces them to make design decisions about the interface for the new logic.

And that design happens independent of what they are about to implement to satisfy the test case. They run the test case, just in case it already runs. If it runs, and they didn't expect it to, they find out why it works, then go on to the next test case. If the implementation isn't clean and simple, by which I mean if it involves duplicate code, or techniques that seem to be too complicated for the task at hand, they search for a way to restructure the existing system so they could implement the test case cleanly and simply.

This is the second place design happens in XP. One of the strengths of this "situated design" is that it happens in the context of real code, not speculation, so the programmers are unlikely to make big mistakes if they did, the code would look ugly or the tests would break and they would back up , and they are unlikely to put too much into the design. They look back over what they did, and see if they can see any new opportunities for simplification. Once again, they do this design situated right in the code.

This results in designs that are very good at expressing what the system actually does, not a design that is good at what thought, in the days of their ignorance, the designers thought the system might do. So, XP projects undergo intense scrutiny of every aspect of their design many times every hour by pairs of programmers who believe in squeezing every last possible drop of excess complexity out of their system.

And they continually develop and execute a battery of tests to make sure that the resulting system does what it set out to do. This doesn't sound like hacking to me. You tell me, though, is this just hacking? How would you categorise XP in the area of techniques for software or system development? Is it a new paradigm?

Is it a new process? Is it a new method? Or is it just new way of programming? XP is a step towards a new paradigm of software development. In the older paradigms, software was compared to existing activities, like mathematics, civil engineering, poetry, or electrical engineering. But software development is really fundamentally different than anything humans have done before, so any argument by analogy about how to do it is bound to limit its potential.

XP starts from the premise that programming is programming, but that you have to add some activities to sustain it over time- like testing and refactoring. It is also a new process what Alistair Cockburn calls "big-M methodology" , because it covers the development of the system from birth to death.

It is most certainly not a new way of programming. All the techniques in XP are nearly as old as programming itself. They were abandoned in favour of more complicated techniques to make up for technical weaknesses, like programming languages that didn't support enough abstraction mechanisms and databases that didn't support structural change. XP revives these techniques, relying on their synergistic effects and advances in technology to make up for their weaknesses.

So, if we talk about the usual evolutionary system development process, how does XP fit into it? XP is a set of techniques for making evolutionary system development work well in the business world. And work indefinitely. And I must say that evolutionary development is far from usual in the clients I see. Of course, that could just be my luck, but That brings me to the question whether XP is a technique only for object-oriented programming or software development?

Did you ever try to use it under other circumstances? XP relies on the ability to keep the software you are writing soft, for keeping the cost of change from ever shooting up.

Objects make it possible although not certain that you can keep the cost of change reasonably low. Other software technologies have more trouble keeping the cost of change low, but it isn't impossible. We thrashed around for a couple of hours trying to figure out how to proceed when someone suggested we "do it extreme". So we wrote stories, cut scope to fit our time and page budget the book focuses on planning and testing , accepted responsibility for tasks, continually integrated using Ward's fabulous Wiki-Wiki Web server , constantly refactored It has been a enjoyable and enlightening process so far- not least because no one can figure out who wrote what paragraphs.

From the customer's perspective, XP is about managing the situation where you have too much to do. You have to estimate, set priorities, track changes. I certainly do a better job of avoiding over commitment now than I did before I started with XP it's still a problem from time to time, of course. If I understand it correctly, there are several aspects in extreme programming that are not "extreme". What I mean is the following:. The ideas of pair programming and collective code ownership lead to teams that don't have experts anymore.

The team is a group of people who tend to have the same knowledge. This seems to imply that it is difficult to use special features that are only known by certain people. I wonder whether this approach isn't a problem in software development where special knowledge is necessary. If you try to get the best of new technologies it seems quite risky not to have experts in the team who program "extreme" close to the edge.

You could have stopped that last sentence right after "risky".
