What are the disadvantages of consistency concept?

The consistency concept in accounting can lead to inflexibility, as it requires organizations to use the same accounting methods over time, potentially hindering the adoption of more effective approaches. It may also obscure changes in financial performance if companies stick to outdated practices that do not reflect current economic realities. Additionally, strict adherence to consistency can complicate comparisons across companies or industries that may have adopted different practices, reducing the overall usefulness of financial statements.
