The so-called "known unknown" matrix is popularized by Donald Rumsfeld and divides our knowledge into four quadrants: Applied to software development, let us consider what the knowns and the unknowns for the feature team would be. As an example, let us assume that the software is an OCR program that recognizes car license plate numbers based on heuristic algorithms. In Software 1.0 (the traditional software), bugs and feature requests are two cases when software updates are needed.
