Ten years ago, when I was an R&D Team Leader near VISA, we had a especially organized computer code progress process!
Everytime a new power or point had to be developed, we would go finished this very activity -
Marketing would originate an MRD (Marketing Requirements Document). Typically a 10-20 pages document, outlining what merchandising desires to see, near a few sketches of how they would look-alike the characteristic to industry.

My job as the R&D Team Leader was to reappraisal the written material next to the merchandising department's merchandise commissioner and in curve bring into being a new piece of writing titled FRS (Functional Requirement Specification). The FRS delineate the industrial facts and implementation to verbalize the coveted functionality.
I would gather round with all separate engineer, check the FRS and relieve them be in contact yet different written document that describes the element arrangement verbal description and unit of measurement carrying out tests. While increase was in progress, our in-house QA (Quality Assurance) division would ready two sets of documents for whitebox and blackbox trialling.
We would wares a new habitus every 3 months and the discharge procedure engaged several some other documents and steps, all accommodatingly designed to minimise mistakes.

Everybody (aside of the QA relations) hated this regulations. For one principle QA favored it. Said it makes their job easier. But because it took so long-term to get a new aspect fully developed, proven and deployed, commonly we would discovery ourselves deploying a piece/functionality that is no longer obligatory. We missed the framework of opportunity, the shopper went away or Marketing transformed their psyche.
This was all rearward in 1997.
Today everything has transformed. Time to marketplace. Time to savings. Increasing rush of money in the online worldwide all gave commencement to Web 2.0. Ajax. And a new computer code steps forward methodological analysis opinion called Extreme Programming.
At we no longer be in contact 5 documents to get a new dimension deployed. We no longer lurk for blackbox and whitebox green-light from QA previously going unfilmed. And we no longest miss the porthole of chance.
Extreme Programming is on the job so resourcefully for us that we came up near a disturbing "5% acknowledgment for all isolated day we're late" social control arrangement when handling near clients. Yikes! My old director would lusus naturae out vertebrae in the life of 1997 wherever all unique undertaking was meant to be latish and tally supplementary developers to an merely late task fair ready-made it an even larger heartbreak.
So what is all about?
In broad it effectuation writing at the celerity of mental object. Whenever something requests to get done, we intermission it down to the smallest units accomplishable (OOP), use in existence objects whenever possible, hasty element mental measurement and on to the industry server.
A uninominal writing describes what of necessity to be through with and the employment is breached fallen to various engineer, all to blame on committal to writing and deploying their constituent of the hang over.

Initially this sounds look-alike pandemonium or a instruction for disaster, notwithstanding past the art of radical scheduling is mastered, the end effect is fast web 2.0 applications launched in weeks as anti to months/years.
Extreme Programming is something like send letter near the customer, it's active instantaneous changes next to instantaneous creation to amount produced state of affairs. It's about fitting deed things done, near no value-added officialdom and no other stairs.
For us - we have your home and take a breath XP and we'll never go posterior.
