Timeline & funding, coupled.
Also called: Project plan & budget · Phased funding plan · Cashflow timeline · Milestone-and-money map
A phased plan that ties each milestone to the cash it needs, where that cash comes from, and a buffer for the slip.
Time and cash are one system, not two documents. Map the phases, attach the money each one needs, name the funding source, and hold a buffer. A milestone slip is also a funding event, so plan for both at once or neither survives contact with reality.
What a timeline and funding plan is
It is one plan that holds two things at once: when the work happens, and what each piece of work costs to do. Most first-timers keep these apart, a Gantt chart on one screen and a budget spreadsheet on another. That separation is where projects quietly fail, because the two are the same system viewed from different ends.
Here is the coupling that matters. A milestone is not just a date on a chart; it is the moment a tranche of cash gets consumed and, often, the moment the next tranche needs to arrive. When tooling slips four weeks, you do not just move a bar to the right. You hold staff or suppliers idle, you push the production run into a different cashflow month, and the buffer you were relying on for launch marketing gets eaten by the delay. The slip is a funding event whether you planned for it or not.
So the plan answers four coupled questions in one view: what are the phases and their milestones, how much cash does each phase need, where does that cash come from, and what happens to the money if a phase runs late. Answer them on separate documents and the answers drift apart. Answer them together and you can see a slip coming before it becomes a crisis.
The plan, on one page
The clearest way to build it is to lay the phases down a single table and read time and money across each row together. Here is what that looked like for the proofing box we ran through the framework, so you can see the shape of a good answer rather than a generic template.
Read the table across, not down. The tooling row is where time-risk and cash-risk meet on the same line, and that is precisely why it carries both a date buffer and a money buffer. Notice the funding source recycles as the project earns, so the plan is not a single fundraise but a sequence.
- One straight line: prototype, tool, ship, sell, all dates assumed to land first time.
- Budget kept on a separate sheet, never read alongside the timeline.
- No buffer on tooling, the one phase most likely to slip.
- A slip becomes a scramble for emergency cash, on bad terms.
- Each phase carries its own cash figure and named funding source on the same row.
- The lumpy tooling cost gets a time buffer and a cash buffer of its own.
- A two-month reserve absorbs the slip everyone knows is coming somewhere.
- A late milestone is rescheduled, not refinanced in a panic.
The optimistic plan is not wrong because it is ambitious. It is wrong because it treats time and money as separate problems, so when the date moves nobody has worked out what it does to the cash until the cash runs short.
How it fits the bigger picture
Timeline & funding is one of the closing activities of Stage 05 Define. It takes the scope set by the design brief and the MVP and turns it into a sequence the team can fund and run. Next comes QFD analysis (05.10.05), which translates customer needs into engineering targets the design work in Stage 06 will be measured against.
What it can do
It makes a slip survivable. Because every milestone is tied to the cash it consumes and the source that funds it, you can see months ahead that a four-week tooling delay pushes the production run into a thin cashflow month, and act before the gap opens rather than after. It turns “we ran out of money” into “we knew that was coming.”
What it can’t do
It can’t make an underfunded project funded. If the numbers do not close even with a sensible buffer, the plan tells you that early, which is a service, but it will not invent the missing cash. And it can’t predict the exact slip; it can only make sure one slip does not topple the whole sequence.

Try it yourself
List your phases down one column. Beside each, write the cash it needs and where that cash comes from. Now pick the phase most likely to slip and ask the systems question: “if this lands a month late, which funding does that break, and do I have a buffer that absorbs it?” If the answer is no, you have found your real risk before it found you.

Project notes: the four-week tooling slip
▸ From the notebook · optional reading
Building the phased plan with Dan and Anna Hartley in Stockport, and the buffer that turned a tooling slip from a crisis into a Tuesday.

Dan arrived with a clean Gantt chart and, on a different tab, a budget. Both looked tidy. I asked one question: “Show me, on the same page, what happens to the money if the ceramic tooling lands a month late.” He couldn’t, because the two documents had never met.
What we built instead
We rebuilt the plan as a single table, phases down the side, cash and funding source across each row. Prototype was cheap and spread out, funded from savings. Tooling in Stoke-on-Trent was the lump, one large payment before a single unit shipped, with the small innovation grant earmarked against it. The first production run of 500–1,000 units carried the BS EN 61010 testing and the bill of materials, paid up front against sales that hadn’t happened yet.
The moment it earned its keep was the buffer conversation. “Tooling and certification are the two phases I’ve never seen land on time,” I said. So we put a four-week time buffer on tooling and a cash reserve covering roughly two months of fixed costs. Dan thought it was over-cautious. Anna, who had managed schedules before, did not.
Where it paid off
The ceramic tooling slipped. Of course it did, it always does. Four weeks, near enough exactly the buffer we had set. Without the plan, that slip pushes the production run into a month where the grant hadn’t cleared and the first DTC revenue hadn’t landed, and you are suddenly emailing your bank from a position of weakness. With it, we slid the run four weeks, the reserve covered the fixed costs, and nobody had to refinance anything in a panic.
The lesson the Hartleys took away was the one that matters: a date on a chart is also a number on a bank statement. Move one and you move the other. Plan them apart and the gap finds you at the worst possible time.
