The PDSQ is a validated measure of customer-perceived quality of physical distribution service — the logistics and order fulfilment processes through which goods are delivered from seller to buyer. Bienstock, Mentzer, and Bird (1997) developed the PDSQ to fill a gap between general service quality measures (SERVQUAL) and the specific quality dimensions most relevant to physical product delivery and logistics service. The three PDSQ dimensions reflect the core attributes of physical distribution performance as perceived by recipients. Timeliness captures the degree to which orders are delivered when promised and within the expected timeframe — whether the product arrives on schedule. Availability captures the degree to which the desired product is in stock and available for ordering in the quantities required — whether the customer can get what they want, when they want it, in the quantity needed. Condition captures the degree to which products arrive undamaged, complete, and accurately matching the order — whether the physical product arrives in perfect condition with no discrepancies. Bienstock et al. (1997) demonstrated that all three PDSQ dimensions independently predict overall distribution service quality satisfaction and that Timeliness and Condition are most strongly linked to customer repurchase intent. The PDSQ has been widely used in B2B logistics research, supply chain management, and e-commerce fulfilment research. It is particularly valuable for evaluating third-party logistics providers (3PLs) and delivery service quality in online retail contexts where physical fulfilment is a critical service quality dimension.
7-point Likert (1=strongly disagree to 7=strongly agree); three subscales scored separately; subscales averaged
Timeliness — TIM (5 items): degree to which orders and deliveries arrive within the promised or expected timeframe. 7-point Likert (1=strongly disagree to 7=strongly agree). Items averaged.
Availability — AVA (4 items): degree to which desired products are in stock and available in the required quantities when needed. 7-point Likert. Items averaged.
Condition — CON (4 items): degree to which products arrive undamaged, complete, and accurately matching the order specification. 7-point Likert. Items averaged.

The PDSQ was developed and validated in business-to-business (B2B) distribution contexts; it has subsequently been adapted for business-to-consumer (B2C) and e-commerce delivery quality research. All three subscales should be reported separately. In B2C online retail contexts, Condition items are particularly sensitive to packaging quality and carrier handling; in B2B contexts, Availability is the most strategically critical dimension affecting production and inventory planning. The PDSQ is distinct from general service quality measures (SERVQUAL, eTailQ) in its exclusive focus on physical product distribution outcomes; it does not capture customer service, website quality, or information-based dimensions. Supplement with customer service responsiveness measures when a comprehensive e-fulfilment quality assessment is required.
