Buying rather than building, honestly costed

Both routes cost more than the visible price.

Purchased materials carry a licence fee and the contextualisation, validation and maintenance effort that follows. Built materials carry the authoring cost and the same downstream effort, plus the capability question of whether anybody available can write them.

The comparison is frequently made on the licence fee alone, which favours building, and then the building is done by somebody with no time, which produces materials worse than the pack.

The honest comparison includes who will maintain them when the unit is superseded. A provider with no internal authoring capability is committing to buy again, and should establish what that costs before choosing to build once.

Hybrid arrangements work well and are underused: buy the content, write the assessment. Assessment is where contextualisation matters most and where a provider's own knowledge of its industry and learners is greatest.

Whatever the route, the materials remain the provider's responsibility. A finding against a purchased resource is a finding against the provider, and the supplier's assurances are not a defence.

The other cost that decides build versus buy is validation. Materials a provider wrote must still be validated, and doing that properly on a large internally authored suite is a substantial recurring commitment that is rarely included in the comparison.
