Project Overrun Prevention Software

Most project overruns aren't sudden, they're visible weeks earlier in the data nobody was looking at. Here's how RAG status and live budget alerts catch overruns while there's still time to act.

By the time most project overruns get discussed, they're already a fact rather than a risk. The conversation happens at delivery, or close to it, when there's very little room left to do anything except absorb the cost or have an awkward conversation about scope with the client. The frustrating part is that the data showing the overrun coming almost always existed weeks earlier. Nobody was looking at it.

Overruns Rarely Happen Suddenly

A project doesn't usually blow its budget in one dramatic week. It happens gradually: a phase runs slightly long, a piece of scope creeps in without a change request, an engineer spends more time than planned resolving something unexpected, and each of these individually looks minor. The problem is cumulative, not sudden, which means it's genuinely preventable if someone is watching the trend rather than waiting for the final number.

The reason this so often goes unnoticed until it's too late comes down to review cadence, not lack of care. If budget consumption is only checked at month-end, or only when a client asks, a firm is by definition finding out about problems roughly a month after they started, at minimum. Every week without visibility is a week where corrective action, whether that's re-scoping, reassigning work, or having an early conversation with the client, wasn't possible because nobody could see it was needed.

Why RAG Status Works Better Than a Single Number

A percentage of budget consumed is useful, but it doesn't tell you what to do with the information on its own. Red, amber and green status thresholds turn that number into an action trigger: green projects don't need attention, amber projects need a quick check on whether the pace is a one-off or a pattern, and red projects need an immediate, documented decision.

Hourglass uses a straightforward structure: projects below 75% of budget consumed sit in green, between 75% and 90% move to amber and need someone to understand what's driving the consumption and whether it's recoverable within the remaining scope, and above 90% turn red, where the right response is an active decision, not a wait-and-see approach. The discipline that actually prevents overruns isn't the traffic light itself, it's the habit of reviewing amber and red projects every week and recording what was done about them.

The Three Options When a Project Is Heading Over Budget

When the data shows a project is tracking to overrun before it completes, there are only really three responses, and the earlier they're made, the more of them are still available:

Reduce remaining scope to bring the project back within the original budget, delivering slightly less than originally planned.

Absorb the overrun as a deliberate, informed decision, accepting lower margin on this engagement and feeding the reason into how similar work is scoped or priced in future.

Have a commercial conversation with the client about additional investment, ideally framed around a specific piece of scope rather than a vague "we're running over."

All three are reasonable choices. What actually damages margin and client trust isn't picking one, it's discovering the overrun late enough that none of them are realistically still on the table.

What Overrun Prevention Software Actually Needs to Do

Update budget consumption the moment time is logged, not on a delay or a manual export cycle.

Apply RAG thresholds automatically, so a project moving into amber or red is visible without someone having to go looking for it.

Surface overdue milestones alongside budget status, so a firm can see schedule risk and budget risk together rather than checking two separate places.

Make the weekly review genuinely fast. If checking project health requires opening several tools and reconciling numbers, the review simply won't happen every week, and the whole point of catching problems early is lost.

How Hourglass Approaches This

Hourglass calculates RAG status automatically as time is logged against each project's budget. Budget alerts and overdue milestone flags surface directly on the dashboard, so a project manager or delivery lead can see everything at risk across the whole portfolio in one screen, rather than opening each project individually to check.

Frequently Asked Questions

Are the 75% and 90% RAG thresholds fixed, or can they be changed?

Today the thresholds are fixed at 75% (amber) and 90% (red) across all projects. Per-project or per-client threshold customisation isn't currently available.

Does this replace the need for a formal project retrospective?

No. Live RAG tracking is about catching problems while a project is still in flight. A profitability retrospective at project close, comparing planned versus delivered margin, is a separate and equally important discipline for improving how future projects are scoped.

Does budget tracking work at a phase level, or only for the whole project?

Budget and RAG status are currently tracked at the whole-project level rather than by individual phase. Milestones can be used within a project to mark delivery checkpoints and flag when a deadline is at risk.

Live RAG status and budget alerts, so overruns get caught while there's still time to do something about them.
