Clear & consistent phasing: Structure that prevents rework

Annual budgeting is a lot like building a house. Each step relies on the one before it—and when the order's off, the whole thing falls apart.

But that kind of sequencing is easier said than done. In our recent budgeting survey, a third of finance leaders admitted their budget phases sometimes overlap and lack consistency.

In this post, we’ll cover the hidden and all-too-obvious costs of fuzzy phasing. Then, we’ll share a few ways to bring more structure to your process without slowing things down.

The costs of fuzzy phasing

1. Rework compounds

The worst kind of work is rework. And budgeting season is the worst time for rework.

Poorly-defined phases have a tendency to invite do-overs: teams start building their budgets before upstream inputs are finalized, then have to redo major pieces once those inputs shift.

Here’s a common example: the sales team builds a workforce plan before GTM targets are finalized. A few weeks later, leadership raises the org-wide revenue target. Now both finance and sales are back to square one with the comp bands, hiring plans, and capacity models they’ve already spent hours refining.

These problems usually stem from one thing: no clear definition of “what needs to be true to start” and “what done looks like.” Without those markers, phases bleed into one another.

2. Decisions stall

Every budget phase needs three things: an owner, a deadline, and definition of done. If any are missing, decisions can circle the runway for weeks, burning time, patience, and momentum all the while.

Think about the marketing department waiting to finalize next year’s campaign calendar. GTM targets aren’t locked, so the same question—“are we planning for three campaigns or four?”—bounces from meeting to meeting without resolution.

3. Scope creeps

Late-breaking budget changes may put a few extra gray hairs on the FP&A team, but they’re part of the game. When made in good faith, they keep the budget grounded in reality.

That being said, there needs to be a line in the sand. At a certain point, upstream inputs need to lock so downstream teams can proceed. This is what clear phasing provides.

Without it, teams keep building on shifting ground. Budgeting drags on, and the longer it takes, the staler the inputs become. By the time version 12 is finished, vendor prices may have changed. Or maybe headcount assumptions have become outdated. Now, you have the unenviable task of going back to partner teams to re-validate your assumptions.

Defined phases create natural freeze points. They give finance a way to lock what’s done and agree on which changes are no longer up for debate. That boundary is what keeps scope creep from turning into an endless loop of redos.

How to improve your budget phasing

Just about everyone in our survey said they have some sort of budget phasing in place. But plenty lacked the structure and definitions that make all the difference.

Here’s how to draw clear lines around your phases to keep your budget moving forward without retracing your steps.

Clearly define owners, deadlines, and definitions for each phase

40% of respondents in our survey admitted their phases lack clarity. It’s easy to pay lip service to these items without taking the time to define them upfront.

So, when you’re scheduling budget phases, make sure these three things are nailed down:

1. An accountable owner

Every phase of the budget needs someone on the hook for keeping things moving. Department heads juggle a dozen priorities on a daily basis, so leadership needs to make it clear upfront that budget quality and timeliness are non-negotiable.

Make ownership visible through a simple Gantt chart or shared tracker that lists key owners, milestones, and dependencies. And don’t just share it with the folks doing the work—loop in all relevant stakeholders, including senior leaders. When the budget is treated as a company-wide priority and not just a finance request, it’s far more likely to stay on track.

A quick alignment meeting can also go a long way. Take 30 minutes to walk through:

• The Gantt chart and key milestones
• Where to find core assumptions and data sources (e.g., revenue, inflation, hiring)
• Where to access relevant templates and reference materials

Set the tone early and you’ll save yourself weeks of chasing down inputs later.

2. A visible, realistic deadline

Don’t give budget owners a three-week deadline and then disappear until it’s due. Finance should check in weekly to make sure departments are on track. Do they have any blockers? Could they use some help with shifting assumptions?

Standing office hours can work well here—an open forum where department leads can bring questions or flag issues before they snowball.

3. An explicit definition of done

This is where many teams trip up. Too often, a phase ends with something like “I think we’re done now.” That almost always means you’re not.

Instead, define it explicitly. For example:

“The preliminary budget is locked when every department has submitted their inputs and FP&A has reviewed the model assumptions. Only then does it move to leadership for gap review and prioritization.”

This is the kind of clarity you should be aiming for. Everyone knows where the finish line is and what needs to happen in order to cross it.

Set clear entry criteria before you kick off a new phase

Without clear and strictly-enforced stage gates, phases are more suggestions than actual checkpoints. And when the next phase starts too early, you end up layering new work on top of in-flux assumptions.

We get it—kicking off the next phase before the previous one is 100% done can be tempting.  You’re staring down a budget deadline and trying to keep the momentum going. But more likely than not, you’re going to pay for it later in rework.

Avoid this trap by setting clear entry criteria. Before launching a new phase, ask: have we locked the inputs and decisions this phase depends on? For example: don’t greenlight revenue forecasting until leadership has finalized top-line GTM targets and growth assumptions. Otherwise, you're setting your team up to rerun models when those assumptions inevitably move midstream.

Bring in partner teams early, but not too early

Finance can’t build an entire budget by themselves. Cross-functional input is critical—according to our survey, about 60% of finance teams bring in other departments within the first 30 days of starting a new phase. That timing generally works. It’s early enough to capture real-world constraints, but not so early that you’re asking for feedback on half-baked assumptions.

Take revenue planning, for example. Sales and CS should weigh in after finance builds the directional model, but before it’s shared with the board. That way, their input is grounded in something real and still early enough to influence the final numbers.

When in doubt, use this rule of thumb: bring in stakeholders once assumptions are stable, but before decisions are set in stone.

Keep everyone grounded in a single source of truth

It’s hard to run a clean process when everyone’s working off a different version of reality. To keep phases moving in sync, you need a shared source of truth—one place where the whole team can see what’s done, what’s in progress, and what’s coming next.

This can be a full-fledged dashboard, or even something as simple as a centralized doc, Notion page, or spreadsheet. It just needs to be updated in real-time and visible to everyone.

This doc should show:

1. The current status of each phase
2. Who owns what
3. What’s due when
4. What’s expected from each team

Just as important: define entry and exit criteria in plain, actionable language. No hand-wavy “we’re mostly done” check-ins. Done should mean: all departments submitted their inputs, the model is signed off by FP&A, and variances are under 5%.

Make budgeting a relay rather than a free-for-all

To recap, clear and consistent phasing requires:

• Assigning an accountable owner for every phase
• Defining visible, realistic deadlines
• Locking in an explicit “definition of done”
• Setting strict entry criteria before starting the next phase
• Bringing in partner teams early—but not too early
• Grounding everyone in a shared, real-time source of truth

Nail these, and you’ll save your team hours of rework while setting the stage for more effective collaboration—a topic we’ll tackle in the next installment of this series.
