Public sector procurement is bound by transparency, fairness, and value-for-money principles. Once minimum thresholds are met, evaluation must be based on pre-published weighted criteria (often combining price, quality, sustainability, and social value). Sole reliance on price or location would breach fairness and equal treatment obligations. Weighted scoring ensures that decisions are objective, defendable, and aligned with responsible sourcing principles. This also allows ethical and sustainability considerations to be formally scored alongside commercial ones, reinforcing good governance.

Liquidity measures a company's ability to meet short-term obligations. The current ratio = current assets ÷ current liabilities, indicating whether the business can cover debts due within one year. Ratios above 1 suggest healthy liquidity, though excessively high ratios may show underutilised cash. Gearing reflects debt-to-equity (solvency); ROI assesses profitability; total asset turnover measures efficiency. Responsible sourcing requires buyers to evaluate liquidity to ensure suppliers have the working capital to maintain operations and deliver reliably. Poor liquidity is a red flag for potential supply disruption.

Engaging with business managers while making sourcing recommendations ensures that the buyer considers multiple perspectives, reducing potential biases and improving decision-making. This approach aligns with ethical sourcing practices by promoting collaboration and transparency in tender decisions.

The correct answer is financial stability (this is done by using all of those lovely ratios in chapter 1.3) and capacity and capability (which are part of Carter's 10 Cs).
At PQQ stage you're looking purely at whether the supplier is good or bad (to put it simply). You don't give them details of your requirement yet, so they're not providing a quote / pricing structure / price schedule at this point in time. That would be at the next stage, IF they pass PQQ, when you issue the tender competition.

Advertising in a local newspaper for a specialized requirement can lead to irrelevant bids, delaying the process. Efficient sourcing practices recommend targeted advertising to reach qualified suppliers, ensuring timely responses and reducing assessment time, especially for urgent needs.
