The Data course as one arc, from literacy up to strategy

Five layers form one arc from individual literacy up to strategic accountability; each depends on the one below.

The Data course as one arc, from literacy up to strategy Two regions. Top region is a five-row stack from L1 Literacy at the base to L5 Strategy at the apex; each row names the discipline and the canonical anchor. L4 Applied is emphasised in red soft. Bottom region is a learner-progression wave: five circular milestones along a horizontal axis, labelled Literacy, Quality, Governance, Applied (emphasised in solid red), Strategy, connected by brand-red prerequisite arrows. A red-accent callout names why a weak lower layer breaks every layer above.

The Data course teaches one arc: from individual literacy through quality and governance into applied work and up to strategic accountability. A weak lower layer poisons every layer above. DAMA-DMBOK 2 is the cross-cutting reference; each named layer has its own anchor.
