In an era where organizational agility, innovation, and digital transformation are heralded as competitive imperatives, projects of all shapes and sizes are launched with increasing frequency. Yet despite advances in methodologies like Agile and Lean, the failure rates of projects remain persistently high. Even in the best of circumstances, without a disciplined approach to business cases, investment evaluation, requirements, outcomes, benefits, stakeholder alignment, high-level roadmapping and design upfront, organizations leave strategic, financial, and operational value on the table.
The evidence for why robust upfront work is critical is sobering. Studies covering millions of projects reveal:
Recent research into large-projects paints an even more alarming picture. According to Bent Flyvbjerg and Dan Gardner’s, How Big Things Get Done, which analyzed a database of 16,000+ large projects worldwide:
Taken together, these figures expose a stark truth: execution risk is real, pervasive, and costly. With such high odds against success in complex initiatives, organizations cannot afford to start projects on a whim.
Every project consumes organizational resources, money, talent, leadership bandwidth, and opportunity cost. Writing a thoughtful business case forces decision-makers to ask: “Is this the right thing to invest in?” A robust business case clarifies:
Without this discipline, organizations risk investing in projects that create little value, duplicate efforts, or divert resources from higher-impact opportunities. In fact, research shows only one-third of companies consistently prepare a business case for new projects, and 60% don’t measure ROI on projects, which undermines strategic decision-making.
A detailed business case enhances accountability and prioritization. It allows leaders to compare competing investment opportunities objectively, allocate capital where it will have the greatest impact, and revisit assumptions if conditions change.
Perhaps the single largest contributor to project failure is poor or incomplete requirements. Standish data consistently points to this:
Requirements serve as the foundation for planning, budgeting, design, execution and testing. They translate business needs into actionable work. When requirements are vague or incomplete, teams make implicit assumptions, scope creeps, rework proliferates, and outcomes drift away from stakeholder expectations.
Human psychology also plays a role. Research on the planning fallacy shows that people tend to underestimate time, costs, and risks, and overestimate benefits when planning complex tasks, even when they have historical data to base estimates on. This cognitive bias is rampant in project planning, leading organizations to start work before they truly understand what they are undertaking.
This bias is exactly what Flyvbjerg and Gardner describe as a common cause of project failure. They argue that many projects start prematurely with superficial planning, a rush to action that feels productive early, but ultimately leaves hidden risks unaddressed. The authors’ core recommendation is to “think slow, then act fast”: take the time to analyze, model, and stress-test assumptions before execution. Other principles from their research, of relevance include:
Write a business case and evaluate competing opportunities, and leadership investment decisions become more rational and data-driven. This discipline helps organizations:
Upfront requirements and high-level design help teams visualize what done looks like. This clarity reduces scope creep, rework, and the friction that occurs when priorities shift mid-project.
Well-defined outcomes and benefits also make it easier to measure project success, and ensure that the delivered solution actually solves the business problem it was intended to address.
By systematically thinking through outcomes, benefits, assumptions, and design, organizations identify key risks early, from technology challenges to stakeholder conflict and build mitigation strategies. In a world where the majority of projects are “challenged” or fail, explicit risk analysis pays dividends.
A rigorous upfront process aligns stakeholders around objectives, expectations, and resource needs. When stakeholders collaborate early, especially business owners and delivery teams, user involvement rises, which in Standish research is another strong predictor of success. It builds team cohesion, alignment on the problem to be solved or opportunity to be addressed. It sets the platform for change and buy-in at the earliest stages.
The data are clear: most projects don’t succeed the first time, and many fall into trouble because organizations underestimate complexity, overestimate readiness, race into execution, and fail to do the hard thinking up front.
Spending time on quality business cases, evaluating competing investment options, and gathering robust requirements, outcomes, benefits, and high-level designs isn’t “bureaucracy” , it's a strategic investment in laying the foundations for successful change. It sharpens decisions, increases alignment, reduces waste, and tilts the success odds in your favor.
Organizational leaders who infuse discipline into the front end of projects, while still enabling execution excellence, are more likely to deliver real value, on time, within budget, and with the benefits promised. As How Big Things Get Done and decades of project research make clear, starting with clarity and planning isn’t optional, it’s foundational to success.
We help organisations shape projects, deliver excellence, and realise change and outcomes that stick. We support organisations before, during, and after projects with an end-to-end service where our domain specialization comes to life.
Before (Inception): We work with you to clearly define the idea, vision, strategy, and business case for change, as well as help select the right partners, and establish governance.
During (Execution): We help deliver project and change objectives while keeping implementation under control through structured governance and assurance to realise intended outcomes.
After (Value Realisation): We ensure outcomes deliver measurable value and embed continuous improvement from successes and learnings.
