Hit and miss. It’s pretty equivalent to % of finding product market fit in startup land.
Mostly worked on internal products. One HUGE hit, a few moderate hits, and quite a few failures.
The calculus for projects at a large bigco are different from a startup though.
It’s not necessarily clear bottom line revenue, especially for innovation teams. Crypto, for example, bigco needs at least some folks working on it to build an understanding of the technology, market, pain points. Some of these projects are started with literally no intention of profitability, but as an explicit build-to-learn.
There’s a wide spectrum of SWE interest and capabilities. Some folks love the creativity of greenfield new product exploration. Others love the focus of crafting a perfectly scalable, maintainable system. These are really just points along a product lifecycle.
I understand myself enough and am unapologetic about getting “bored” easily, and need to be constantly working on creative things.
Others at the other end of the spectrum have a visceral reaction to that. They can’t do what I do, and I can’t do what they do.
