Further Reading I vividly remember one of my first sightings of a large software project. I was taking a summer internship at a large English electronics company. My manager, part of the QA group, gave me a tour of a site and we entered a huge depressing warehouse stacked full with cubes. I was told that this project had been in development for a couple of years and was currently integrating, and had been integrating for several months.
You may need several methods 1. The Need for Flexibility To succeed at software development you need to be flexible in your choice of software development method, to choose the right one for the job. There are several reasons why it is important to do so: Different technologies require different techniques.
Object-oriented methods are best-suited for Extreme programming xp essay using object-oriented technologies whereas data-oriented methods are best-suited for data-oriented applications. Every individual is unique.
People are not replaceable parts. Each person has a different background, different preferences for the way in which they work, and different cognitive style e. An approach that works incredibly well for you might be impossible for me to grasp, and vice versa.
Every team is unique.
Because teams are made up of individuals, and because individuals are unique, each team will require a unique way for them to work in order to maximize their potential.
Your external needs vary. Some projects must conform to government regulations. Other projects are highly-dependent on suppliers, such as technology vendors or software development outsourcers, and therefore must tune their process to reflect the ways that their suppliers need to work.
Different types of projects, see belowrequire different approaches because each category has different priorities and goals.
Each category of methodfor example agile and rigorous, has its strengths and weaknesses. An organization gets the process that it deserves. Categories of Method For the purpose of our discussion there are four different categories into which a method, such as DAD or Extreme Programming XPcould fall into: This approach to development is chaotic and often unplanned, or when it is planned the plan is quickly abandoned.
Estimates and schedules, when made at all, are rarely met in practice. Software processes in this category are well defined and often include detailed procedures that developers are expected to follow in a more-or-less serial manner.
For example requirements are identified, reviewed, and accepted. The analysis of those requirements is performed, reviewed, and accepted.
The design is defined, reviewed, and accepted. There is room for feedback between phases, although that feedback is provided via a reasonably defined procedure and the changes are then reviewed and accepted as before.
Systems are typically delivered on an incremental basis where the releases are on the order of several quarters or years in length. Software processes in this category are well defined and often include detailed procedures that developers are expected to apply in an iterative manner.
For example requirements may be initially defined at a high-level with the detail later identified on an as needed basis. Small portions of your system are fleshed out, with software potentially delivered on an incremental basis following short release cycles often on the order of weeks or months.
Agile is an approach to software development that is people oriented, that enables people to respond effectively to change, and that results in the creation of working systems that meets the needs of its stakeholders.
Software processes in this category are defined at a high-level, often presented as a collection of synergistic practices or philosophies. Each method category appeals to a different mindset.
For example, code and fix methods are attractive to maverick developers, often referred to as cowboys, that prefer to work alone with little guidance.Literate Programming (Lecture Notes) [Donald E.

This anthology of essays from Donald Knuth, the father of computer science, and the inventor of literate programming includes early essays on related topics such as structured programming. In Extreme Programming Explained, the first book written about XP, Kent Beck includes hand-drawn sketches of class diagrams and other free-form diagrams.
In fact, in the second edition he includes a mind map in the inside cover overviewing XP.

Abstract: We're living in yesterday's future, and it's nothing like the speculations of our authors and film/TV alphabetnyc.com a working science fiction novelist, I take a professional interest in how we get predictions about the future wrong, and why, so that I can avoid repeating the same mistakes.
Extreme Programming (XP) is an agile software development methodology which is intended to improve software quality and responsiveness to changing customer requirements. It emphasizes business results first and takes an incremental, “get something started” approach to build the product, using continual testing and revision.
XP (Extreme Programming) is a form of Agile software development. This site contains Bill Wake’s essays on XP, Agile, Lean, Scrum, and related topics.
