There's an old IEEE article about the billions of dollars lost due to software project failures: https://spectrum.ieee.org/why-software-fails https://spectrum.ieee.org/why-software-fails We don't hear of such failures any more because software projects (or products) no longer "fail" in the traditional sense -- they turn into endless money sinks of re-architectures, re-platforming, tech debt repayment or expensive maintenance, that can continue as long as the company has cash. When the company does run out of cash, it is difficult to say to what extent tech expenses or lack of revenue due to slow software delivery played a part.
