Why Multi-Year Projects Rarely Go as Planned and How to Stay in Control

When organizations embark on large transformation programs, they often expect a straight road from business case to delivered ROI. But the reality of multi-year projects looks more like a winding path with sudden turns. Assumptions made at the beginning rarely stay stable over the journey. Costs shift, strategic priorities evolve, and unexpected external projects alter the playing field. Without active steering, leaders find themselves surprised by an eroding business case.

At BlinC, we believe the key is not to treat the business case as a one-time calculation, but as a living instrument that must be tracked and adjusted throughout the entire transformation.

How Assumptions Drift Over Time

Imagine a business case created in 2021 to migrate a portfolio of applications to the cloud. At the time, cloud providers offered one pricing model, and infrastructure cost was forecast with a reasonable margin. Two years later, new competitors entered the market and changed their license structures. What was assumed to be a stable recurring cost suddenly shifted—sometimes upward due to additional mandatory services, sometimes downward because of aggressive discounts. Both directions have real impact: a cost increase erodes ROI, while a cost drop may free up funds for new initiatives.

Another example: a global bank planned a multi-year program to consolidate data centers. Midway, the company launched an enterprise-wide AI initiative requiring GPU-intensive infrastructure. The sunk costs of new hardware investments changed the picture dramatically. The original “savings” from closing old data centers no longer carried the same weight, because part of the cost base had already been absorbed elsewhere.

These examples show that no cost element is ever truly fixed in multi-year journeys. Licensing fees, infrastructure spend, even labor rates evolve—and every shift changes the original story told by the business case.

Strategic Shifts and Intangible Value

Costs are not the only moving target. Strategy itself evolves. Consider a telco that justified a three-year CRM upgrade primarily on expected efficiency gains. Halfway through, the company’s focus shifted toward customer trust and data protection due to new regulations. Suddenly, the “intangible” benefits of compliance and customer confidence became far more valuable than the efficiency savings originally modeled.

If those benefits are not re-evaluated and re-weighted, leaders risk undervaluing the very outcomes that now matter most. This is why a frozen business case often fails to reflect the reality of a changing strategic environment.

The Hidden Danger: Surprises Too Late

The biggest risk of ignoring these shifts is not that projects fail—it’s that they appear to succeed until the very end. Budgets are spent, milestones delivered, but when leaders look at the final numbers, they discover that the promised ROI has evaporated.

This “late surprise” is one of the most damaging outcomes for any organization. It erodes trust, slows decision-making, and creates resistance to future transformation efforts. Executives begin to question not just the project, but the entire governance process.

How BlinC Keeps Projects in Control

BlinC’s methodology is built to prevent these late surprises. We treat the business case as a living contract between expectations and reality. Instead of locking it in at the start, we monitor and adjust it across the full lifecycle of the project.

•  Cost element tracking: License fees, infrastructure, and operational costs are continuously monitored. Any shift—up or down—is fed back into the value model.

• Impact of external projects: If a parallel initiative such as a cloud migration, data center exit, or system decommission alters sunk costs, our methodology recalibrates the business case to show the real picture.

• Strategic re-weighting: When company priorities shift, we re-evaluate intangible benefits like agility, compliance, or customer trust, and show their adjusted impact on overall ROI.

• Proactive governance: With updated insights, executives can decide to accelerate, pivot, or even pause initiatives before surprises emerge.

A Story of Control

One of our clients, a large regional enterprise, launched a five-year transformation program aimed at modernizing its digital channels. Midway through, cloud prices spiked, and new competitors forced a shift in customer experience priorities. Instead of discovering the business case had eroded after billions were spent, the company—using BlinC’s methodology—was able to re-model the ROI in real time. They shifted budget to customer experience features that brought new revenue streams while managing infrastructure costs proactively.

The result: the program not only stayed financially viable but delivered value in areas that mattered most to the business at that point in time.

Stay in Control of Your Transformation

Multi-year projects will always face shifting assumptions. Costs will move, strategies will evolve, and external factors will change the playing field. The difference lies in whether these changes are tracked and acted upon—or ignored until it’s too late.

BlinC empowers organizations to stay in control of their value journey. We ensure that your business case remains relevant, transparent, and aligned with reality—so you realize ROI without surprises.
