Since its inception over two decades ago, the primary objective of business intelligence  has been the creation of a top-down single source of truth from which organizations  would centrally track KPIs and performance metrics with static reports and dashboards. This stemmed from the proliferation of data in spreadsheets and reporting silos throughout organizations, Often yielding different and conflicting results. With this new mandate,  BI-focused teams were formed, often in IT departments, and they began to approach the problem in the same manner as traditional IT projects, where the business makes a request  of IT, IT logs a ticket, then fulfills the request following a waterfall methodology.
