Aperture 1
Intent
Name the product decision before you open a chart. If nobody can state the decision, tracking work pauses.
Custom framework
Analytics Lens for App Analytics decisions
A four-aperture model we teach inside Portal Vectorcore programmes: Intent, Instrumentation, Interpretation, and Intervention.
Aperture 2
Instrumentation
Map the minimum events and properties required for that decision. Refuse speculative “might need later” fields.
Aperture 3
Interpretation
Separate mix shifts from behaviour shifts. Write the story in plain language before you format a slide.
Aperture 4
Intervention
Log the action, owner, and review date. App Analytics without intervention is museum curation.
Where the Lens shows up in coursework
Cohort Signal Lab uses the Lens as a critique rubric. Instrumentation Audit Sprint compresses apertures one and two into a two-week cleanup. Stakeholder Signal Briefings emphasise aperture three so executives hear decisions, not chart archaeology.
If your team already owns a mature data warehouse practice, the Lens still helps product partners stay aligned — it is deliberately lighter than a full analytics engineering curriculum.
