Informal influence is the power a person has to shape what others think, feel and do without holding any formal authority over them. In most organisations, it quietly decides whether a change succeeds or stalls. The informal influence gap appears when the people who truly shape change are not the people named on the project plan.
You have probably seen it. The executive sponsor announces the new system. The steering committee signs off the timeline. Yet the team waits to hear what one long-serving colleague thinks before they decide whether to take it seriously. That colleague has no leadership title, no budget and no seat at the table, but their opinion travels faster than any email. This guide explains why that gap exists, what it costs, and how to work with it responsibly.
| Quick answer
The informal influence gap is the distance between who holds formal authority in a change program and who actually shapes how people respond to it. To close it, find the trusted connectors and credible voices across your organisation, involve them early with honest information, and measure real adoption rather than agreement. |
What Is Informal Influence at Work?
Informal influence is the ability to affect other people’s attitudes and behaviour through trust, expertise, relationships or reputation rather than through position. A manager has formal authority because the organisation gave it to them. A colleague has informal influence because their peers chose, usually without saying so, to listen to them.
This idea has deep roots. Research on how new ideas spread, summarised in the diffusion of innovations theory, shows that people tend to look to trusted peers, often called opinion leaders, before they adopt something new. Titles rarely come into it.
It is not good or bad in itself. It can lift a change program or sink it. What matters is whether you can see it, and whether you treat it with respect.
The Informal Influence Gap: A Story Most Change Leaders Recognise
Picture a Canberra government department rolling out a new case management system. The program has a capable sponsor, a clear business case and a thorough training plan. The org chart says the change will land through twelve team leaders.
On the floor, though, the real conversation happens around one person. Priya has worked there for fourteen years. She is not a manager. When someone hits a tricky case, they ask her. When the new system is announced, she says nothing publicly, but at lunch she mentions that the old workflow “always worked fine.” Within a week, half the team is keeping spreadsheets on the side.
Nothing about the plan was wrong. The sponsor simply never saw the network that carried the message. That is the informal influence gap, and it is a close cousin of problems we have written about before, such as the change translation gap, where strategy gets lost between leaders and frontline teams, and the buy-in illusion, where people nod in meetings but never adopt the change.
Formal Authority vs Informal Influence
The two work differently, and confusing them causes many change problems. Here is a simple comparison.
| Formal authority | Informal influence | |
| Source | Job title, reporting line, budget | Trust, expertise, relationships, reputation |
| Visible on the org chart? | Yes | No |
| How people respond | Comply because they must | Follow because they choose to |
| Speed of message | Follows official channels | Travels through conversations |
| Effect on change | Sets direction and gives permission | Shapes belief and real adoption |
Strong change programs need both. Formal authority sets direction and removes barriers. Relationship power turns that direction into daily behaviour. If either one is missing, the change stalls.
Why Change Programs Miss Informal Influence
Nobody ignores informal influence on purpose. It slips through because of how organisations plan and report.
- Stakeholder maps follow the org chart. Most maps list roles and reporting lines, so they capture formal power and miss relationship power.
- Leaders sit far from the floor. Senior people rarely overhear the corridor conversations where opinions form.
- Consultation means meetings with managers. Feedback gathered through management layers filters out the voices that matter most.
- Informal leaders stay quiet in public. They often speak up only in trusted circles, so workshops rarely reveal them.
- Success is measured by attendance. Counting who showed up to training says little about who believes in the change.
Add a change fatigue effect, such as the one described in The Adaptation Tax, and people lean even harder on trusted peers to tell them what is real and what is noise.
Five Types of Informal Influence You Will Meet in Organisations
The connector
Connectors know everyone and link teams that rarely speak. When they share news, it reaches across the organisation in a day.
The trusted expert
People go to the expert when they are stuck. If the expert dismisses a new tool, others quietly follow. If the expert endorses it, adoption rises.
The culture carrier
Long-serving staff hold the unwritten rules about how things really get done. Their stories shape what newcomers believe is possible.
The early adopter people copy
Some colleagues try new things first, and their peers watch closely. When they succeed, others feel safe to follow.
The credible sceptic
Not every informal leader is an enthusiast. A respected sceptic can raise real issues the project has missed. Treat them as a source of insight, not an obstacle.
What the Informal Influence Gap Costs a Change Program
Adoption that looks healthy but is not
Training completion and survey scores can look excellent while people carry on the old way in practice. Peer influence is often the reason.
Rumours filling the silence
When informal leaders are not given honest information, they fill the gaps with guesses. Those guesses spread quickly and are hard to correct.
Lost credibility
If a program is seen to bypass trusted people, employees read that as a sign that leaders do not understand the work. That damages what we call change credibility and spends down organisational trust.
Delay that compounds
A stalled change does not stay stalled neutrally. The longer the real issues go unaddressed, the more expensive they become, a pattern we explore in The Change Debt Problem.
How to Find Informal Influence: A Seven-Step Method
You do not need a software tool to begin. Work through these steps in order.
- Ask “who do you go to?” In short, private conversations, ask people who they turn to for help, advice and honest opinions about work.
- Look across levels and silos. Do not stop at your own department. Influence often sits with people who bridge teams.
- Watch behaviour in meetings. Notice who people look at before they answer, and whose comments change the room.
- Ask frontline managers. They usually know who really shapes opinion on their team, even if the answer surprises them.
- Run a simple network survey. Three questions are enough: who do you ask for advice, who do you trust, and who helps you get things done? The method is a light version of social network analysis.
- Look for patterns, not popularity. Count how often the same names appear, and from how many different groups.
- Validate privately. Check your picture with a trusted colleague, and never publish a list of “influencers”. Labelling people can damage the very trust that gives them influence.
Researchers such as Rob Cross have written widely on how work really flows through networks, and you can explore that thinking at Connected Commons.
How to Work With Informal Influence Ethically
There is an obvious temptation here: find the influencers and use them to spread the message. That approach usually backfires, because people can tell when a trusted colleague is being used. The goal is partnership, not persuasion.
- Involve them early. Ask for input before decisions are final, so their feedback can change something real.
- Give honest information. Share the reasons, the trade-offs and what is still unknown. Scripts and spin destroy credibility quickly.
- Welcome the hard questions. A credible sceptic who is heard often becomes the strongest supporter.
- Do not overload them. Informal leaders already carry social weight. Adding unpaid change work without recognition leads to burnout.
- Recognise their contribution. Acknowledge their role publicly if they are comfortable with it, and privately if they are not.
- Close the loop. Tell them what changed as a result of their input. Nothing builds trust faster.
This approach fits well with long-established models. Kotter’s eight-step approach to change stresses building a coalition of people from across the organisation, and the Prosci community has long emphasised the role of sponsors, managers and change champions. That missing link is what makes those roles work in practice.

Frequently Asked Questions About Informal Influence
What is informal influence in the workplace?
Informal influence is the ability to shape other people’s opinions and actions without formal authority, usually because of trust, expertise, relationships or reputation.
What is the difference between formal and informal leadership?
Formal leaders hold a position that gives them authority over others. Informal leaders have no such position, yet colleagues follow their lead because they respect or trust them.
How do you identify informal leaders during organisational change?
Ask people who they go to for advice, watch who shapes opinion in meetings, talk to frontline managers and run a simple network survey. Look for names that appear across several teams.
Who are change champions and change agents?
Change champions and change agents are people who support and promote a change within their team or area. The strongest ones often hold real sway with colleagues, which is why they are worth involving early.
Can informal influence be built?
Yes. People build it through reliability, useful expertise, fair treatment of others and strong relationships over time. It cannot be assigned, but it can be earned and recognised.
Which change management course should I take first?
Most professionals begin with the Change Management Foundation course, then move to the Practitioner level when they are ready to lead change in practice.
Final Thoughts: Make Informal Influence Part of the Plan
The informal influence gap is not a flaw in people. It is a blind spot in how we plan change. Org charts show where authority sits, but belief travels through relationships, and relationships rarely appear on a project plan.
Look for the trusted voices, ask them honest questions, share honest answers and measure real adoption instead of polite agreement. When formal authority and informal influence pull in the same direction, change stops feeling like something done to people and becomes something done with them.
