Why secondary data might prove to be inaccurate for a firm specific purposes?

Secondary data may be inaccurate for firm-specific purposes due to differences in context, timing, and methodology. It may not reflect the unique circumstances or specific market conditions of the firm, as it was collected for different objectives or by different researchers. Additionally, secondary data can be outdated or biased, which can lead to misleading conclusions when applied to current situations. Consequently, relying on such data without thorough validation may result in poor decision-making.
