BlueChip Tech Solutions, a software firm, is preparing its annual performance review. The company recently saw a sharp increase in its Current Ratio, but surprisingly, its Quick Ratio remained stagnant and low. The CFO noted that while the Gross Profit Margin is industry-leading, the Net Profit Margin is significantly lower than competitors due to high administrative overheads. Furthermore, the Inventory Turnover Ratio has been declining steadily over the last three quarters. Despite these internal struggles, the company maintains a very low Debt-to-Equity Ratio, as the founders prefer internal funding over bank loans. The board is now debating whether these ratios indicate a "safety cushion" or "inefficient asset management." The gap between BlueChip Tech’s high Gross Profit Margin and low Net Profit Margin suggests a theoretical weakness in which area of management?
