The nine-section intake framework.

A companion to IoT Connectivity at scale with T-Mobile for Business. This is the intake framework itself: all nine redesigned sections, screen by screen, and the cascading constraint logic that makes each answer narrow the next.

01 / Framework stepperAll 9 sections · ownership on the rail

Information → Resource Assignment. Each section opens to a redesigned screen.

Click any of the nine steps, or use Back / Next, to open its redesigned screen full-width below. No scrolling tricks; the stepper stays put. Real fields from the legacy Salesforce form, redesigned. Every section applies the same four moves: semantic grouping, gate questions first, smart defaults with visible provenance, downstream consequences stated inline.

Section 01 / 09

Representation. The production screens live in T-Mobile's Salesforce org and can't be shown directly; this mock is rebuilt in HTML with the real field names, grouping, and derivation logic from the shipped redesign. Data values are illustrative.

02 / Decision logicCascading constraint graph

Vertical drives Network. Network drives Hardware. Hardware drives Security.

The decision graph below shows the dependency chain the redesigned framework enforces. Choosing Vertical = Supply Chain & Logistics narrows Network to 3 options (from 8), which narrows compatible OEM models to 11 (from 30+), which drops the SIM specifications that won't apply.
