Approach
Presenter First concentrates on transforming each of a customer's requirements into a well tested, working feature as quickly and with as much correlation to the customer's story language (requirement) as possible. The language of the story or requirement is used to directly guide development of the feature – even naming the modules and function calls. As a consequence, the feature implementation tends to closely represent the customer's desire with little extraneous or unneeded functionality. The language of the source code also corresponds closely to the customer's stories.
Presenter First is often applied in graphical user interface applications. It is equally well applied to the development of command-line interfaces. Further, a slight variation of the approach has been used effectively in embedded software; here the integral design pattern is known as Model-Conductor-Hardware and the approach is termed Conductor First.
When used in GUI applications, this approach allows the presentation logic and business logic of the application to be developed in a test first manner decoupled from on-screen widgets. Thus, the vast majority of the application programming can be tested via unit tests in an automated test suite. In so doing, the reliance on GUI testing tools to perform extensive system testing can be reduced to verifying basic GUI operation or eliminated entirely.

Famous quotes containing the word approach:
“I maintain that Truth is a pathless land, and you cannot approach it by any path whatsoever, by any religion, by any sect.”
—Jiddu Krishnamurti (1895–1986)
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
“Fishermen, hunters, woodchoppers, and others, spending their lives in the fields and woods, in a peculiar sense a part of Nature themselves, are often in a more favorable mood for observing her, in the intervals of their pursuits, than philosophers or poets even, who approach her with expectation. She is not afraid to exhibit herself to them.”
—Henry David Thoreau (1817–1862)
