Consolidated EIDT results by engagement state, decision rule, and decision-support implication
| Digital proficiency tier | Highest weighted-payoff intervention by engagement state | Final intervention selected under decision rules | Decision-support implication | Advantage of the EIDT over other technical approaches |
|---|---|---|---|---|
| High | Strong: In-house mentorship; Moderate | Online tutorial under all rules | Although the highest-payoff intervention varies across engagement states, online tutorials provide the most robust overall choice across the rule set | The EIDT identifies a balanced option under behavioural uncertainty rather than relying on a single-state optimum |
| Online tutorial; Weak: Self-paced study | ||||
| Medium | Strong: In-house mentorship; Moderate: In-house mentorship; Weak: Self-paced study | Self-paced study under maximax, Laplace, Hurwicz, and minimax regret; Online tutorial under maximin | The medium tier shows that recommendations change with decision posture: self-paced study is attractive under upside, average, and regret-based reasoning, while tutorials are preferred under downside protection | The EIDT makes organisational risk posture explicit in intervention selection |
| Low | Strong: In-house mentorship; Moderate: In-house mentorship; Weak: Self-paced study | Self-paced study under maximax; In-house mentorship under maximin and Laplace; Self-paced study under Hurwicz and minimax regret after tie-break with in-house mentorship | The low tier shows the greatest decision tension | The EIDT surfaces this ambiguity, and resolves it transparently through explicit tie-break logic, showing where intervention choice is finely balanced rather than artificially definitive |
