Week 20: Construction of the Beta Prototype

PLTW Element G, Iteration 2 — Construction of a Testable Prototype, at production grade.

Build the Beta

  • Construct the Beta prototype following your Week 18 integration plan and Week 17 selected design.
  • Follow production-grade practices: code review before merging, tests for critical paths, a documented build/deploy procedure — the same discipline a real engineering team would use, not just “make it work.”

Fully Integrate All Sub-Systems

  • Confirm every sub-system from your integration plan is actually connected end-to-end, not built and tested in isolation only.

Log Build Results vs. Revised PRD

  • Run your first Beta test pass and log results against the revised PRD (Element C, Iteration 2) targets — the stricter bar, not the Sprint 1 bar.
  • Note where the Beta already beats the Alpha’s Sprint 2 baseline, and where it doesn’t yet.

Core Deliverables

  • Working, fully-integrated Beta prototype.
  • Production-grade build/deploy documentation.
  • First Beta test results logged against the revised PRD.
