The RI may increase the cost of the product

The Average outgoing quality level (AOQL) is the minimum defective rate that can reach the customer over long run

In RI the rejected lots are subject to 100% inspection

RI will make the product cheaper.

The RI improves the quality of the outgoing goods

The tolerance remains the same within a given size range.

As size range increases, the tolerance decreases.

In manufacturing processes with unbalanced distribution, the Selective assembly may lead to some surplus parts.

The application of Selective assembly is only effective in low-volume production.

Selective assembly requires 100% inspection.

Selective assembly leads to limited interchangeability.

The application of Selective assembly is aiming to improve the surface finish.
