Most strategies don’t fail because they’re flawed.

They fail because organisations underestimate what it takes to change.

After nearly two decades leading and advising on global transformations in international organisations, from biotech and pharma to telecoms and tech startups, I’ve seen the same pattern repeat itself:

A compelling strategy is launched… which then quietly unravels in execution.

Not due to poor thinking, but because the human side of change was treated as an afterthought.

In today’s VUCA environment (volatile, uncertain, complex, ambiguous), strategy and the ability to lead change are no longer separate capabilities. They depend on one another.

Strategy sets direction. How you lead change determines whether you get there.

A strategy defines where you want to go.

Leading change determines whether your organisation is willing and able to follow.

Too often, change management is reduced to a communications plan or a late-stage rollout activity. In reality, it should be embedded from the very beginning, influencing the decisions that shape the strategy itself.

And this is key, because strategy gets implemented by people, and their understanding and buy-in are essential to its success.

Case in point

The strategy that looked perfect on paper

In one global transformation I led, the executive team had developed a robust, data-driven growth strategy. The logic was sound and the ambition was clear.

But six months into implementation, progress had stalled.

Why?

• Leaders weren’t aligned on what the strategy meant in practice.

• Middle management felt excluded from the process.

• Employees experienced the change as something being done to them, rather than with them.

We paused execution to rebuild engagement:

• We involved cross-functional teams in translating strategy into action.

• We created forums for honest dialogue, not just top-down communication.

• We equipped leaders through tailored training to lead change, instead of just announcing it.

Only then did momentum return. We did not change the strategy but focused on changing the approach to people.

Engagement is not a “nice to have”. It’s the engine of execution

“One of the biggest misconceptions I encounter with senior leaders is this: ‘We don’t have time to involve everyone.’ The reality is, you don’t have time not to.”

Engagement is not about consensus decision-making. Leaders still need to make tough calls. But people are far more likely to commit to decisions when:

• The rationale is clear

• The process feels fair

• Their perspectives have been heard

In another transformation programme, we involved frontline teams in redesigning processes that directly affected them. This dramatically improved the quality of solutions and reduced resistance almost entirely.

Because people support what they help create.

What leaders consistently underestimate

Across organisations, I see three recurring blind spots:

1. The cost of disengagement

Disengagement doesn’t always show up as open resistance.
It shows up as:

• Passive compliance

• Slow adoption

• Quiet attrition

And it quietly erodes strategy execution.


2. The need to change mindsets alongside processes

You can restructure teams, implement new systems, and redefine KPIs.

But if underlying beliefs and behaviours don’t shift, the organisation will default back to old ways of working.

Sustainable transformation is both operational and behavioural.

3. The leadership capability gap

Many leaders are strong strategists, but not necessarily strong change leaders.

Leading change requires:

• Emotional intelligence

• Clarity in communication

• The ability to hold tension and uncertainty

• Consistency between words and actions

Without this, even the best strategy will struggle to land.

What effective change-led strategy looks like in practice

From my experience, successful transformations consistently do five things well:

1. They start with people

While leadership teams naturally focus on strategic objectives, project plans, and business outcomes, employees are often focused on uncertainty, workload, role clarity, and their ability to succeed in a new environment. Effective change leaders take the time to understand these perspectives and address them proactively.

2. They involve employees early

They engage employees in shaping elements of the strategy where possible, especially in design and implementation. When people feel informed, involved, and supported, they are far more likely to embrace change rather than resist it.

3. They communicate with honesty

They acknowledge difficult impacts and address them openly. Honest communication and transparency help build credibility.

4. They equip leaders at every level

Change cascades through dialogue, and some of these conversations can be hard. Ensure your leaders are trained or coached to handle them well.

5. They treat change as a continuous process

It is paramount to treat change as an ongoing capability. Rather than a one-off initiative.

The most successful organisations don't view change as a project with a defined end date. They build the mindset, skills, and leadership capabilities needed to continuously adapt and evolve. In a world where market conditions, technology, and customer expectations are constantly disrupted, the ability to navigate change becomes a core organisational competency and competitive advantage.

The bottom line for senior leaders

If there’s one takeaway I would highlight based on my experience, it’s this:

“Strategy success is not determined at the point of design, but at the point of adoption.”

And adoption is fundamentally human.

People rarely resist change itself. They resist confusion, inconsistency, and uncertainty.

But when people are engaged, trusted, and empowered, they don’t just accept change. They drive it.
