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).

On Greatness What’s important to you in the development of a product? One of the things that really hurt Apple was that after I left John Sculley got a very serious disease. And that disease — I’ve seen other people get it too — it’s the disease of thinking that a really great idea is 90% of the work, and if you just tell all these other people “here’s this great idea,” then of course they can just go off and make it happen. The problem with that is that there’s just a tremendous amount of craftsmanship in between a great idea and a great product. And as you evolve that great idea it changes and grows. It never comes out like it starts, because you learn a lot more as you get into the subtleties of it, and you also find there are tremendous tradeoffs you have to make, there are just certain things you can’t make electrons do, there are certain things you can’t make plastic, or glass, or factories, or robots do. And as you get into all these things, you find that designing a product is keeping 5,000 things in your brain, these concepts, and just fitting them all together and continuing to push to fit them together in new and different ways to get what you want. And every day you discover a new problem or a new opportunity to do it a little differently. And it’s that process that is the magic.
