This paradigm had replaced the procedural approach of programming, but it also introduced shortages on parts like cross-cutting abilities where a feature can affect most parts of a system. The most prominent example of this might be a logging facility where detailed information for each method execution is logged for auditing, or you can think of exception handling where errors that occur across the layers of the application are handled at a single point and applicable measures are immediately taken to address the issues.
