Architect - Scoping & Estimation (Internal)

Never client-facing. The unit each step is sized in, its S/M/L/XL bands, and the role mix - one section per step, in step order. Hours per step per tier are in the effort model; the tier model and prices in productisation.md. Bands and tiers are defined in depth.md.

2.1 Experience & Content Structure

Unit: IA size (nodes / page types)

Band Approx size
S ≤20 nodes
M 20–50 nodes
L 50–100 nodes
XL 100+ nodes

Role mix:

  • Principal sets structure and leads the content-model pass
  • Mid develops detailed IA and journeys

2.2 Technical & Delivery Definition

Unit: Integration kind & volatility (kind matters more than count - most projects carry analytics and perhaps form submissions; business systems are the step change)

Band Description
S Analytics only
M Analytics + form submissions / email
L + business systems (CRM etc.) - Core tier and up
XL Multiple / volatile / custom APIs

Role mix:

  • Principal-heavy (risk + architecture)

2.3 Visual Direction

Unit: concepts × rounds, multiplied by design complexity (ambition band). Hours per tier and band multipliers (System-led 1× · Expressive 1.5× · Premium 2×) in the effort model.

Role mix: design-led; principal reviews direction before client playback.

2.4 Scope & Priorities

Unit: number of workstreams triaged.

Role mix: principal-led (trade-offs are commercial decisions); mid documents.

2.5 The Cornerstone

Effort model: fixed effort per project plus a size component from the 2.1/2.2 bands (assembly scales with IA nodes and integration count; the boilerplate sections do not). 2.5 varies ~2.4× across tiers while the research-heavy steps vary ~4× - near-fixed by design; if assembly hours exceed the model, the Cornerstone prompt isn't doing its job.
