I don't find KPIs terribly useful in the software development at the level of an IC (which is btw my own level), unless we talk about performance & latency of large services where it is very useful and helps save millions. Software IC is special because motivation-wise it is almost self-sustaining, which is evident from massive open-source participation and pet projects.
On the contrary, at larger scale (starting from middle management and all the way to the top), I have an educated opinion that structured measurement of KPIs and clearly defined goals is what differentiates "tech" companies from all the rest - which is to say, tech-companies are known for their powerful growth.
It's really obvious in the hindsight: managers are usually pretty disillusioned types and will avoid doing hard work unless properly incentivized, thus fine-grained unforgeable growth-adjacent KPIs are really at the heart of the tech-company's success. Overall corporation's fast growth is a direct consequence of the synergy of KPI growth across the org-chart.
