Build — Execute with Discipline

Turn baselined intent into a testable system — protect the minimum, march with discipline.

Build phase — team executing with discipline, turning a baselined design into a real, testable product.

Step Inside

Build is the march — where ideas earn their keep as integrated, testable systems.

If Plan chose the hill and Design mapped the route, Build is the march — where ideas earn their keep as integrated, testable systems under real constraints. The discipline that makes it work starts with protecting the minimum: ship an M3VP (minimum-minimum-minimum viable product), the smallest real thing a customer can see, touch, or test, and use it to attack your usability, feasibility, and viability risks.

The cautionary tale is Microsoft's Longhorn: build without guardrails and even the best-funded team spins into a "corporate cyclone" of churn until it has to hit reset. The Right-Sized path avoids that. Start from a solid CDR — a contract between design and build, all liens closed. Get every test asset ready on Day 1 and schedule scarce, bottleneck resources like production assets.

Lean on modularity and standard interfaces (TCP/IP over bespoke couplings) so subassemblies build and integrate in parallel. Treat your supply chain as strategic partners — and bring the same discipline to software supply: a bill of materials, dependency, license, and vulnerability tracking. Buy proven FPGA IP or pretrained AI rather than building everything from scratch.

Embed SOPs and quality rather than inspecting them in. Keep one verified configuration baseline. And close the loop with feedback to designers so every build teaches the next. Ship, then learn — done is better than perfect.

"It doesn't matter how good your engineering team is if they are not given something worthwhile to build." — Marty Cagan

Action Plan

From Building to Breakthrough

Four steps to get started

  1. Pressure-Test Your MVP.
    Most teams overbuild. Before scaling, challenge yourself to reduce your minimum viable product (MVP) down to the minimum-minimum-minimum viable product (M3VP).
  2. Engage Three Suppliers as Strategic Partners.
    Supplier relationships can be transactional, but the best suppliers are strategic assets. Identify three vendors in your supply chain and ask them how you can partner more effectively.
  3. Use AI to Accelerate Documentation.
    Use a tool like ChatGPT to generate a draft of a key technical document. Let AI handle the tedious parts so your team can focus on high-value thinking.
  4. Archive Photos at Every Build Milestone.
    Photos are often overlooked, but they're a low-cost, high-value tool for traceability, training, and future diagnostics. Versioning provides the same functionality for software. These records may one day solve problems you didn't know you had.
Build action plan — disciplined execution steps from M3VP through supplier partnerships to milestone documentation.
Build tools — SOPs, configuration templates, and AI documentation aids for disciplined build execution.

Directed Tools and Templates

Build smarter, not harder.

Three hubs keep the build on track. SE Hub holds your SOPs, configuration management templates, and interface documentation. Review Hub covers CDR entry/exit criteria and lien-closure checklists. The main site provides AI-powered generators for documentation, code, and SOPs that compress the build cycle.

Self-Assessment

Build-Phase Health Check

The build phase is where intent meets implementation — and where discipline, not ambition, decides whether you ship. This scores the six disciplines of a right-sized build separately, so you can see which is carrying the march and which is quietly stalling it. Answer honestly; it's a mirror, not a report card.

1 = Never true · 2 = Rarely · 3 = Sometimes · 4 = Often · 5 = Consistently — answer honestly. This is a mirror, not a report card.

Scope Discipline (M3VP & Guardrails) Total possible: 20

1. We reduce the first build to the smallest thing we can show, touch, or test (an M3VP), not a fully featured product.

2. We put something real in customers' hands early and use it to test usability, feasibility, and viability.

3. We guard scope, interfaces, and roadmap fiercely; new "must-haves" are deferred, not absorbed.

4. We sustain momentum with a steady drumbeat of micro-wins and rapid M3VP cycles.

CDR & Build Readiness Total possible: 20

5. Our CDR was complete — design baselined, ICDs published, and all actions/liens closed before build began.

6. All test assets are ready on Day 1 (power, harnesses, fixtures, JTAG/ICE, calibrated instruments, scripted procedures).

7. We treat scarce, bottleneck assets (test stands, chambers, tool chains) as scheduled production resources.

8. We manage concurrency deliberately — time-boxing, standardized changeovers, and extra shifts where they pay off.

Modularity & Standard Interfaces Total possible: 20

9. Our system decomposes into self-contained subassemblies that are assembled and validated in parallel.

10. Every module has clear acceptance criteria, dedicated fixtures, and contract tests.

11. We use standard interfaces (e.g., TCP/IP) instead of bespoke couplings to compress integration.

12. Integration is a smooth, planned process — not a firefight or a dreaded "integration week."

Supply Chain as Strategy Total possible: 20

13. We forecast and continuously track long-lead items (custom parts, rare materials, proprietary IP).

14. We treat key suppliers as strategic partners — pricing leverage, early inventory access, escalation channels.

15. We buy proven capability where it's smart (off-the-shelf parts, FPGA IP cores, pretrained AI) rather than building everything.

16. We keep software supply disciplined: a software bill of materials with dependency, license, and vulnerability tracking.

SOPs, Quality & Configuration Control Total possible: 20

17. SOPs define how work gets done — sequenced tasks, checkpoints, and clear assembly / build-pipeline steps.

18. Quality is embedded, not inspected in — in-process checks, automated tests, and static/dynamic analysis catch defects early.

19. All stakeholders build from a single, verified configuration baseline (hardware revs, software builds, firmware).

20. Documentation reflects the actual product being built, not just the theoretical design.

Build → Design Feedback Loop Total possible: 20

21. We run regular lessons-learned sessions and capture friction points from assembly and integration.

22. Build insights are translated into actionable design and Design-for-Manufacturing improvements.

23. We document relentlessly — photos, part numbers, serials, test results, versions — for traceability.

24. We favor "done is better than perfect," shipping a working system we can test and improve.
