At the end of the day, everything is a people problem. I tried checking the other comment but I couldn't find it (I thought I replied to it actually but it seems it was a different one about non-integrated ERPs).
We are not a conglomerate of 10+ nation size (slightly below that; also not the best measure but trying to toe the line with sharing but not naming gets harder with detail) but I suppose since we had to pivot from financial services to CPG a while ago and B2C retail in our segment at that time really demanded extremely low lag&lead-times for user changes and onboarding of products and services (well, VAS.. but who's counting), we engineered our way out of it, including logistics, SCADA, web, mobile apps, people-onboarding and M&A onboarding.
Having neat BI is more a side-effect than a primary goal. That goal came much later since it was the last remaining driver of shadow processes as it lead to many opportunities of bad engineering, even if it was seen as valuable in the short term (it never was worth it in the long run). It wasn't even about spreadsheets (or excel specifically), it became a real-time streaming issue where you couldn't have a fully manual process in the loop any more and we couldn't hire extra people fast enough to keep the existing processes running at the rate we needed. We don't have data entry positions anymore for the same reason; it's not that we don't receive new data, it's just that we had all B2B contacts agree that they will not send or receive files between humans if it's regarding an automated streaming process.
Having our data architecture being based on real time streaming (and some periodic sanity checks and shadow reconciliation as that is mandated by some record keeping laws) means we beat practically everyone in the same market segment on speed and delivery.
But perhaps this ties in to us being more homogeneous than some other conglomerates. We're not doing more than 5 countries and don't have our acquisitions result in extra divisions as we tend to aim for competitors in the segments we want to grow in (we want the data, the people and the customers, not the systems). This means that the people that operate the business (be it the business processes or the actual product processes) don't really get 'extra' software as a result.
