Personal observation has the disadvantages of being subject to personal bias (since the observer's own opinions and interpretations can influence what they see) and consuming a lot of time (since someone needs to physically observe and record performance). Standardized tests and statistical reports are typically more objective and efficient ways to measure performance. Written reports may also have personal bias, but they do not consume as much time as personal observation.
