Why Good Ideas Fail: The Role of Communication in Making Change Work
When businesses introduce change - whether that’s a restructure, a new process, or a shift in direction - the focus is often on getting the decision right. What’s less often considered is how that change is communicated. In practice, it’s rarely the idea itself that causes problems. It’s how that idea is explained, understood and reinforced across the business.
Guidance from ACAS highlights that poor communication is one of the most common causes of workplace issues, particularly during periods of change. That’s an important point, because it suggests that many of the challenges businesses experience aren’t caused by the change itself, but by how it’s interpreted.
Why Communication Matters More Than We Think
ACAS guidance consistently points to communication as a key factor in issues such as:
conflict between colleagues
misunderstandings around expectations
resistance to change
uncertainty about roles or responsibilities
In many cases, these issues aren’t the result of poor intent; they stem from a lack of clarity or consistency in how information is shared. During periods of change, this becomes even more important.
Without clear communication:
people fill in gaps themselves
assumptions are made
different versions of the same message emerge
And over time, that creates inconsistency across the business.
What’s interesting about this is that communication is often treated as a final step: something that happens once decisions have already been made. But the evidence suggests something different. Communication isn’t just about sharing information; it’s a key part of how change is understood, accepted and embedded.
The Role of Clarity and Manager Communication
Alongside this, wider research consistently highlights the importance of clarity in the workplace. Studies from Gallup have shown that employees who clearly understand what is expected of them are significantly more engaged and more likely to perform well.
That clarity doesn’t happen by accident; it’s created through consistent communication, particularly by managers. During periods of change, managers play a critical role in:
reinforcing key messages
translating what change means in practice
answering questions and addressing concerns
Without that layer of communication, even well-planned changes can feel unclear or inconsistent across teams.
How Larger Organisations Approach Communication
In larger organisations, communication is rarely left to chance, precisely because of the risks that poor communication creates. It’s typically planned alongside the change itself, and often includes:
a clear narrative around what’s changing and why
briefing managers before wider announcements
anticipating questions and concerns
reinforcing key messages over time
The goal isn’t just to inform people. It’s to help them understand, interpret and apply the change in a consistent way.
What Happens When Communication Isn’t Structured
In smaller businesses, communication is often more informal. A message is shared, a conversation is had, and there’s an assumption that people will “get it”. But without structure, people naturally fill in the gaps themselves. When that happens, you often start to see:
different interpretations of the same message
managers giving inconsistent guidance
uncertainty around expectations
resistance or hesitation that isn’t addressed early
Over time, this can make even well-intentioned changes feel unclear or unsettled.
How to Apply This in Your Business
You don’t need a complex communication plan to take a more structured approach.
A few simple shifts can make a significant difference:
Be clear on your message before you share it. If it’s not fully clear to you, it won’t be clear to others.
Think about what people need to understand, not just what you want to say
Focus on what it means for them day-to-day.
Prepare managers to reinforce the message; even in small teams, consistency matters.
Plan what happens after the initial announcement. Communication shouldn’t stop once the message is delivered.
These steps don’t add complexity; they add clarity.
Communication Is Part of the Strategy
It’s easy to think of communication as something that happens after a decision has been made. In reality, it’s what determines whether that decision is understood, accepted and embedded. Taking a more deliberate approach doesn’t mean overcomplicating things; it simply means recognising that how you communicate change will often determine whether it works in practice.
If you’re planning a change in your business, taking a small amount of time to structure how you communicate it can make a significant difference to how it’s received. We’ve created a simple one-page Change Communication Plan to help you think this through in practice.
