Yagni A Definition by Martin Fowler martinfowler.com Yagni originally is an acronym that stands for "You Aren't Gonna Need It". It is a mantra from Extreme Programming that's often used generally in agile software teams. It's a statement that some capability we presume our software needs in the future should not be built now because "you aren't gonna need it".

The State of Agile Software in 2018 A Talk by Martin Fowler martinfowler.com On the surface, the world of agile software development is bright, since it is now mainstream. But the reality is troubling, because much of what is done is faux-agile, disregarding agile's values and principles. The three main challenges we should focus on are: fighting the Agile Industrial Complex and its habit of imposing process upon teams, raising the importance of technical excellence, and organizing our teams around products (rather than projects).

In the Eye of the Beholder An Essay from Field Notes on Science and Nature by Jonathan Kingdon Haven't you noticed?Wordless questioningOutlinesAgents of thought and experiment
Haven't you noticed? I remember my mother sitting me down at the age of about five with pencil and paper to draw an acacia tree in the yard while she busied herself with her own sketchbook. After a while she came over to see my efforts. “Splendid! But haven’t you noticed how the trunk narrows as it rises? And see how the branches flatten out sideways, not like that oleander over there, where they all go up at a steep angle. Now don’t rub that one out, just do another drawing to compare with the first one.” Looking Closely is Everything seeing
Wordless questioning The comparison of forms raises questions and drawing can be employed as a wordless questioning of form; the pencil seeks to extract from the complex whole some limited coherent pattern that our minds and eyes can grasp. The probing pencil is like the dissecting scalpel, seeking to expose relevant structures that may not be immediately obvious and are certainly hidden from the shadowy world of the camera lens.

Outlines Photography teaches us that the very act of putting a line around the edge of an observed object is an artifice. Such outlines rarely appear in photographs, or, for that matter, in nature, and yet…and yet? An outline sketch that bears little relationships to the so-called objectivity of a photograph might actually transmit information to another human being more selectively, sometimes even more usefully, than a photograph. If the brain is unlike a camera in actively seeking outlines, there is the strong implication that “outline drawings” can represent, in themselves, artifacts that may correspond more closely with what the brain seeks than the charts of light-fall that photographs represent.
Agents of thought and experiment The act of drawing serves to remind us that hands are agents of thought and experiment. Photography has a great future, but no matter how much ancillary wizardry photography accumulates, it will not be in competition with “drawing” in the broadest sense of that term. There will always be a role for exploration by the hands, encumbered by no more than a piece of ocher or a stick of charcoal. Its practical utility is as a manifestation of the mind struggling with the meaning of what it encounters and what it wants to explore. thinkingdrawingunderstanding
