Behavioural anchors
| Level | Behaviour at this level |
|---|---|
| N1 Guided | Executes a prepared interface call following documentation and reports recurring error codes to the developer. works under supervision and follows instruction · routine, one variable at a time · own task |
| N3 Proficient | Independently builds an interface between two systems, handles errors and documents the data exchange for support staff. sets own approach and seeks input proactively · several variables, some ambiguity · own team or process |
| N5 Leading | Sets the organisation's integration standards and interface policy and decides on exposure to external parties. sets the standard and the policy · strategic, under high uncertainty · organisation, value chain or profession |
N2 and N4 are deliberately not anchored. Raters place them between the anchors, following the O*NET convention.
