The Sunk Cost Trap: Stopping Runaway Projects

As read on LinkedIn

The Multi-Million Euro Graveyard The hardest thing to do as a leader is admit failure. Especially when that failure revolves around a massive transformation project you championed.

Ego, self-worth, and the fear of losing the respect of your peers push you into a defensive mode. So, you accept yet another major scope increase. You sign off on another delay. You keep hoping it will turn around.

At Coalex, we refer to these as ‘Zombie Projects.’ They continue to drain budget, time, and effort, but they have absolutely no chance of delivering the value promised in the original business case. They are dead, but they keep walking.

In our analysis of Zombie Projects, we rarely find the root cause to be technical failure. Instead, we constantly uncover psychological failure.

The Sunk Cost Fallacy blinds everyone. The fear of “wasting” the millions already spent is greater than the fear of wasting the millions you are about to spend.

The Conspiracy of Silence Once you have invested significant effort and money, you become psychologically committed to proving you were right all along. This behavior permeates every level of the project organization, creating a conspiracy of silence:

For C-Level executives, this is a dangerous trap. The financial ruin and reputational damage of a failed mega-project can push a company to the brink.
For project teams, it results in a “hush-culture.” Fear of career damage or being fired ensures everyone keeps their heads down, hides the red flags, and just pushes on.
For vendors, it’s simple economics. As long as you keep paying change orders to keep the Zombie stumbling forward, and blame cannot easily be pinned on them, they will happily keep the project running indefinitely.

The Architect’s Principle: Zero-Based Future Value The only way to stop a Zombie Project is to bring in an outsider with absolutely no emotional investment in the past spend.

The Coalex Architect applies one brutal principle: Zero-Based Future Value.

We ask: “Forget the budget already spent, that money is gone. If we spend another €2M starting today, will we get more than €2M of business value back?” If the answer is no, the project must stop or pivot.

The 3-Step Recovery Framework Moving from emotional attachment to rational action requires a structured intervention. When Coalex steps into a Zombie Project, we execute a rapid three-step process:

The Tactical Freeze: We immediately halt non-essential spending, hiring, and change orders. You cannot fix a vehicle while driving it at full speed.
Forensic Value Audit: We tear down the original business case and rebuild it based on current reality, not past promises. We separate features that drive hard value from “nice-to-haves.”
The Binary Roadmap: We present the steering committee with two clear, costed options based on the audit: a controlled project halt (shutting down to cut losses) or a Radical Pivot (descoping 60% to save the essential 40%).

Call to Action Do you recognize your own project in the signs of a Zombie?

The “Phase 2” Kick-Can (pushing critical scope into a mythical future phase).
The “Watermelon Project” (Green status reports on the outside, Red reality on the inside).
The Partner Revolving Door (senior vendor leaders have vanished).
The narrative shifted from ‘Value’ to just ‘Survival.’

If so, you are in dire need of an intervention. Contact Coalex for an independent Mid-Flight Health Check. We will tell you the truth about your project in two weeks, so you don’t waste another two years.
