You might have come across a situation in your organisation where one person seem to hold everything together. It may be managing a project or fixing bugs, they are the one everyone calls when systems fail. In short, they are the “Go-To” person.
Now imagine that person is unavailable. On leave. Pulled into another issue. Caught in an offsite. Suddenly, the momentum you built, on projects, initiatives, decisions, begins to slow.
What you are witnessing is a low Bus Factor in action.
What is the Bus Factor?
The Bus Factor is a simple measure: How many people can step away before your system, team, or the workflow is affected?
- A low bus factor means decisions and context are concentrated in the hands of a few.
- A high bus factor means knowledge and ownership are distributed. Progress continues even when individuals are unavailable.
For leadership, this is not a technical issue, it is a structural one. It directly affects your ability to scale, adapt, and sustain the outcomes of any change effort.
A Real World Scenario
Imagine you have been working hard on a project management plan in collaboration for optimizing the process in a department. You are scheduled for a meeting to present it to the top management from different departments. The plan has been built keeping the particular department in mind, which can then be scaled for the organization. You expect some technical questions and the department head would support you by clarifying certain concepts to the management team.
However, on the day of the presentation, that person can’t attend because they were held up offsite.
You proceed with the presentation anyway. But without their presence, the discussion goes off track. The management team doesn’t have the same technical background as the department head, which lead to misunderstandings. As a result, you struggle to convey the message effectively. The meeting ends, but it feels incomplete.
It may seem like only one person was missing, but their absence made it difficult to convey the message clearly. Even though they didn’t hold the highest rank in the company, their knowledge was irreplaceable. If that knowledge had been shared more broadly, the meeting might have resulted in desired actions.
This situation highlights a low bus factor. Knowingly or unknowingly, the entire system becomes fragile when key information is held by just a few individuals.
How can a low bus factor happen?
This risk is rarely designed. It builds up quietly.
- There is always one person who “knows how things work,” and everyone in the team just go to them.
- Over time, others stop engaging with those areas.
- Context becomes invisible. Decisions get deferred to the same few names.
In high-growth or change-heavy environments, this effect intensifies. The people who were present at the start naturally carry the most context, and slowly become the only ones who can move things forward.
It is a risk that grows underneath the surface until it becomes visible, usually at a moment when speed matters most.
The Illusion of Being Irreplaceable
Being “the only one who knows how to do X” can feel like job security but in reality, it’s a risk for both the team and the individual. If you are the only one who knows how to do X, here is how it might affect things:
- For the team, you will be holding accountability in making the decisions and the backup when the team struggles.
- For the company, you’re a single point of failure.
- And for you, you can’t take any timeoff because the company will always have need of you.
Ways to increase Bus factor
One of the ways is through knowledge sharing and collaboration. That’s the reason why organisations encourage documentation. But because of the deadlines, we sometimes skip this step. When this happens overtime, it results in low bus factor.
Here are some of the other ways to increase the bus factor:
1. Document your work
Create SOPs and write things down as you work. Explain your process to others and store it in a place that’s easy for the team to access. Don’t keep things in your head and don’t rely on your memory. This documentation supports both you and your team in future.
You might think that documenting things feels like an extra task instead you can call that person and or like do it yourself since takes more time. But it helps you keep track of your own work and it helps others when they need it.
2. Work in Pairs
Collaborate regularly. Pairing up on tasks allows others to learn from you and you from them. Let others take the wheel sometimes even it’s slower at first.
3. Cross Train Your Team
Encourage team members to switch roles occasionally or shadow each other. When people understand different parts of the system, the team becomes more adaptable and less reliant on a single person for any particular area.
4. Encourage questions
Create a culture where it is okay to ask even about the basics. Learning should be constant. When team members feel safe asking questions, knowledge spreads naturally. Remember, you were once a beginner too.
5. Run the “What If I Disappeared?” Test
Ask yourself: “If I left today, what would break?” Identify those weak spots and take steps to share or document that knowledge.
Systems That Outlast People
The best organisations you have worked with have had people leave, without anything breaking. Why?
Because they did not build around individuals. They built around systems. Microsoft 365, for example, is a good place to start with. We all use Word and Excel in some form or the other. Here are a few of the other tools that we can make use of to lower bus factor:
- Teams: When team conversations are scattered across WhatsApp, emails, phone calls, and random documents, the only way to understand what is going on is to ask someone. But when discussions happen in Teams, with clear channels, threads, and shared files, everything has context. Anyone can catch up. Nobody is the single point of failure.
- SharePoint: Access to files and documents often lives with a few people, and sharing permissions become a bottleneck when they are away. SharePoint changes that. You can structure libraries, assign the right permissions, and create dashboards that let the team self-serve. When ownership is distributed, access does not break when someone takes time off.
- Planner: When tasks are tracked in someone’s notebook or discussed over calls, nothing is visible to others. Planner lets teams track who is doing what, by when, and why. Even if a team member is unavailable, others can step in, follow the trail, and move the work forward without guesswork.
- Visio: Explaining a process verbally or over a Word doc can take time, and still lead to gaps in understanding. But a visual workflow in Visio communicates clearly. When processes are documented as diagrams, they become easier to transfer, hand off, and improve upon. Visio is a great tool to document SOPs and workflows that can be used for training and KT as well.
- Power Automate: People often become bottlenecks for routine actions: sending reports, moving files, or triggering alerts. With Power Automate, those actions can be systemised. Set up flows once, and they will continue to run, whether you are in a meeting, on leave, or have moved on.
There are more tools in Microsoft such as Power Apps, Power BI and Power Pages which helps in capturing how things work, who owns what and what happens next and help keep the knowledge out of your head and in places where everyone can use it.
Make Yourself Replaceable
Many people fear that if they share too much, document too well, or delegate too often, they will no longer be needed.
But here is the truth: If your value lies in hoarding knowledge, your growth is already capped.
Being irreplaceable by gatekeeping makes you a bottleneck. Being replaceable by design makes you a leader.
When you document your work, share your methods, and build systems that others can run, you create leverage. You create freedom. You create space to move up, not stay stuck.
The people who grow fastest are the ones who made themselves replaceable at their current level.
Closing Thoughts
The best leaders build systems that outlast individuals. If someone in a key role steps away and everything halts, that is not just inconvenience, it is design failure.
Resilience is when progress does not depend on one calendar, decisions are not locked behind one person’s availability, and teams are empowered to function when roles shift, projects change or leadership rotates. That is not just operational maturity. It is strategic readiness.
The success of your transformation is not only measured by what you build, but by how independently it can operate. In the long run, it is not about how dependent you are on the best people, it is about how you have reduced that dependency altogether.
At Coffee, we work with leadership teams to design systems that scale. If your digital initiatives rely too heavily on a few key people, it may be time to relook at how your organisation is set up to deliver consistently.
Let us know if you would like to assess your current structure and explore how to build operational resilience into your transformation roadmap.
