What are disadvantages of field report?

Field reports can be time-consuming to produce, often requiring extensive data collection and analysis, which may delay decision-making. They may also suffer from subjectivity, as the observer's biases and interpretations can influence the findings. Additionally, field reports may lack standardization, making it difficult to compare results across different studies or contexts. Finally, they can be resource-intensive, necessitating significant manpower and funding, which may not always be available.
