The Execution Gap – Part 9: Design for Your Culture: Why “Best Practices” Often Fail

Introduction

Leaders are constantly searching for the ultimate execution playbook. They look at what worked brilliantly at a competitor or a tech giant and try to copy-paste that methodology into their own company.

We see this frequently with Agile transformations. Leaders read about the “Spotify Model” of Agile squads and try to force that exact framework into a company that operates completely differently. More often than not, it fails.

The failure does not happen because the methodology was inherently flawed. It fails because it was not adapted to the company’s unique cultural realities.

This is one of the most predictable and preventable failures in organizational change. And yet it keeps happening because “best practice” carries an implicit authority that makes leaders reluctant to question it. An organization is not a machine; it is a biological organization collection of people serving people. Its DNA, communication styles, decision-making norms, risk tolerance, and patterns of resistance vary wildly from one company to the next. When a rigid “best practice” methodology does not fit that cultural DNA, the biology of the organization naturally rejects it. Tailoring your implementation approaches, whether rolling out Agile frameworks, AI tools, or new organizational structures, dramatically improves both adoption and sustainability. The best methodology is always the one your people will actually use.

There is a practical test for this. Before rolling out any new framework, ask your frontline managers: “Does this fit the way we actually work?” If the answer is hesitation or polite deflection, you have a cultural fit problem that no amount of training will fix. The framework needs to adapt, not the people.

The Leadership Shift: From importing best practices wholesale to adapting them to your cultural reality.

How to Make the Shift Today:

✦ Assess Cultural Readiness: Before launching a new framework, evaluate how your company historically reacts to change and adjust your rollout accordingly.

 Adapt the Language: Modify the terminology of standard methodologies to match the language your employees already use and understand.

Start Small: Pilot customized processes in single departments to evaluate cultural fit before attempting a company-wide rollout. Pilot customized processes in single departments to evaluate cultural fit before attempting a company-wide rollout.

 

There is no universal playbook. There is only the playbook that works for your people, in your organization, at this moment in time. At New Oaks Consulting, we bring decades of Fortune 500 experience, but we start every engagement by learning about your cultural biology before we recommend anything. If your organization is working to strengthen execution capability, we would welcome a conversation.

Introduction

This is the second of five articles in our "Shaping the Future of PMO series. Having identified why strategic initiatives fail in Part 1, we now examine the actual cost of execution gaps—beyond the obvious budget overruns and timeline delays —to include the hidden opportunity costs that compound over time, as well as the measurable ROI of building systematic execution capabilities.

Failed projects aren’t just disappointing - they’re expensive.

Last quarter’s “strategic transformation” consumed hundreds of thousands in consulting fees, 18 months of your best people’s time, and countless hours of executive attention. The deliverable? A comprehensive roadmap that’s gathering dust while your team deals with “more urgent priorities.”

Meanwhile, your competitor launched a similar initiative in 8 months and captured the
market segment you were targeting.

This is what the execution gap costs.

Most executives focus on the obvious costs: budget overruns, timeline delays, and consultant fees. However, the real cost of poor execution is the opportunity cost and a lack of effective tracking systems. Every month, your strategic initiatives sit in committee reviews, and your competitors gain ground.

The True Price of Execution Gaps

Remember from Part 1 in this series: 70% of strategic initiatives fail to deliver their intended value. Here’s what that failure actually costs your organization:

✦ Projects that consume 2-3x their original budget

✦ Resources tied up in initiatives that never deliver value

✦ Consultant fees for advice that never gets implemented

✦ Rework and restart costs when initiatives finally get prioritized

Hidden Costs

✦ Market opportunities captured by faster competitors

✦ Employee disengagement from repeated false starts

✦ Stakeholder confidence erosion from missed commitments

✦ Innovation pipeline clogged with stalled projects

Strategic Costs

✦ Competitive positioning is lost to rivals that execute better.

✦ Customer relationships damaged by delayed improvements

✦ Revenue growth stalled by incomplete transformations

✦ Organizational capability gaps that compound over time

The Numbers are Sobering

According to PMO Squad’s 2024 research, 60% of organizations cite measuring results and delivering value as their top concern. Sciforma states in their PMO Outlook Report – 2025 Edition that the most significant issues in financial tracking of projects are as follows:

✦ 38% lack effective forecasting systems for portfolio or project costs

✦ 23% lack systems that integrate with existing financial systems

✦ 23% lack real-time financial data

✦ 8% don’t have good data-gathering financial tools

Here’s what execution infrastructure with data tracking tools in place could deliver instead

Organizations with systematic execution capabilities with data systems in place to track results see:

✦ 20-30% fewer project delays – Strategic initiatives launch when promised

✦ 25-35% reduction in budget overruns – Resources stay focused on what matters

✦ 15-25% better resource utilization – People work on initiatives that actually get completed

✦ 20-30% increase in employee productivity – Teams see their efforts translate into tangible results

The ROI of Execution Excellence

Mini Case Study – Working with a large international company, we quickly realized that having clear success measures and KPI’s was critical for defining and directing success. We reviewed each of our key processes and sought ways to ensure we were executing them effectively.

The first tracking tools we needed to look at were business success tools. We put in place measures like:

✦ Portfolio Results vs. Strategy: Did we achieve the results we expected in the marketplace to meet our company’s strategy goals?

✦ Sales revenue driven by the new project: What current sales figures in the market, with a similar product, were when we started the project, so we could then look at the growth and cannibalization numbers (taking business from our current products) to give us our net increase in sales (dollars and units)

✦ Profit: Are we generating sufficient funds to show a profit on this project?

✦ NPV (Net Present Value): To determine the cost of introducing this new product over time to ensure we were leveraging our resources to get the best results in today’s dollars.

The next area we looked at was the results of other key processes to ensure we were getting
the best results:

✦ Leveraging resources in the right places: we examined the project’s key output (sales or profits) versus the FTE (Full-Time Equivalents) required to execute it successfully.

✦ Stage Gate: We examined each stage gate’s on-time percentage relative to the plan to determine whether our plans were on time and, consequently, whether we were delivering results to the customer on time.

Other detailed metrics were closely monitored, and they aligned with the above.

Together, these results were tracked and reviewed quarterly to ensure we were on target compared to our plans. Any adjustments in plans were then reflected in the new results.

Stop thinking of execution infrastructure as overhead. When done right, it is the highest ROI investment you can make, turning strategic intent into a competitive advantage systematically and predictably.

The question isn’t whether you can afford to build execution capabilities, such as tracking systems and dashboards. It’s whether you can afford not to.
You get what you measure.
