Use this roadmap when the team does not just need another calculation. It organises the work around the decisions that normally matter most: does the idea deserve momentum, which concept should win, how should it be built, and what has to be true before launch.
Roadmap
Start with the phase that matches your current risk. Each step links to the tools and guides that are already live on the site.
Test whether the product solves a meaningful problem and whether the customer value justifies further development effort.
Compare product directions with explicit criteria so the team knows why a concept is being advanced, not just which idea feels strongest.
Reduce technical uncertainty, understand where complexity is accumulating, and decide what needs to be proven before scale-up.
Choose when to stay flexible, when to commit to tooling, and how to stage prototype, bridge, and production methods deliberately.
Work backwards from price and route to market so the product cost target, overhead, and payback logic are grounded in reality.
Bring the product, route to market, and investor-facing story into one view so launch decisions rest on evidence rather than hope.
Where to start
If the project is blocked, the most useful next step is usually the one that removes the most expensive uncertainty.
Start with product purpose, concept selection, and process mapping so the direction is sharper before engineering effort grows.
Use manufacturing payoff, production strategy, and assembly estimation to reduce late surprises around tooling, labour, and complexity.
Work through route to market, target COGS, break-even, startup cost, and cashflow before pushing further spend into launch.
