Why parcels arrive late

Six categories of causes of late parcels on bones above and below the spine, each with causes and sub-causes on horizontal lines: labels never lean, only the bones do. The description names the effect and then every category with its causes; the table has a row for each. Illustrative review, with a phone variant.
