When one team or partner fails to deliver, the impact rarely stays in one place. A delay can hold up someone else's work, change priorities or create unnecessary costs.
Building trust is not about getting everything right all the time. It is about being reliable, communicating openly and taking responsibility when things do not go as planned.
Why trust erodes as companies grow
In a small company, people often work closely together. They know who is responsible for what, understand what others are working on and can usually resolve problems through a quick conversation.
As a company grows, this becomes more difficult. New teams, departments and external partners become involved. People have less visibility into each other's work, and communication becomes more complicated. This can create misunderstandings. One team assumes a task has been completed, while another is still waiting for approval. A partner expects feedback by Friday, but nobody has been assigned to provide it.
These situations do not always mean that someone is unreliable. Often, the real problem is unclear responsibilities, missing information or assumptions that nobody checked. Over time, repeated misunderstandings can weaken trust, even between people who genuinely want to work well together. The goal is not to make everyone aware of everything happening across the company. It is to make responsibilities, commitments and communication clear enough for people to depend on one another.
Four habits that build trust between teams and partners
Team-building activities can help people connect, but trust depends more on what happens during everyday work. How people keep commitments, communicate problems and respond to mistakes has a greater influence on whether others can rely on them.
1. Make realistic commitments and keep them
People need to know what they can expect from you. Instead of saying "We'll send it soon," agree on a specific deadline, such as "We'll send the updated document by Thursday afternoon." Before making a commitment, consider whether you have the time, information and resources needed to deliver it.
It is better to agree on a realistic deadline than to promise something you cannot complete. When people consistently follow through on their commitments, others become more confident in planning their own work around them.
2. Raise problems early
Problems are a normal part of working together. What matters is how and when they are communicated. If you realize that a deadline might be missed, inform the people affected as soon as possible. Explain what happened, what it means for their work and when they can expect an update.
For example, rather than waiting until Friday to announce that a delivery will be late, inform the other team on Wednesday when you first identify the risk. This gives everyone more time to adjust their plans and avoid unnecessary disruption. Early communication does not eliminate problems, but it helps prevent them from becoming bigger ones.
3. Explain decisions that affect others
Not every decision will be popular, especially when different teams have competing priorities. However, decisions become easier to understand when people know why they were made. If a project is delayed, priorities change or a request cannot be approved, explain the reasoning and what happens next.
People may still disagree, but understanding the reasoning helps them adjust their own work and reduces unnecessary confusion. This is especially important when decisions affect people who were not involved in making them.
4. Recognize contributions from other teams and partners
Successful projects rarely depend on one person or department alone. When something goes well, acknowledge the people and teams who contributed to the outcome. If an external partner helped resolve a technical problem or another department made an important deadline possible, recognize their contribution.
This does not require a formal announcement. A simple acknowledgement during a meeting or in a project update can be enough. Recognizing contributions shows that people's efforts are noticed and valued, which helps strengthen working relationships.
Building trust with external partners
Working with external partners introduces additional challenges. Unlike internal teams, partners may not understand your company's processes, priorities or decision-making structure. They also have their own responsibilities, deadlines and ways of working, which makes clear expectations particularly important.
Before starting a project, make sure both sides understand what needs to be delivered, who is responsible for each part of the work and how communication will take place. Agree on who should be contacted when questions or problems arise, and do not assume that the other side has information you have not explicitly shared.
For longer collaborations, regular updates can help both sides stay informed without constantly requesting information. A reliable partnership does not require constant communication, but it does require the right information to reach the right people at the right time.
Repairing trust after a missed commitment
Even reliable teams and partners occasionally miss deadlines or make mistakes. When this happens, avoiding the issue or making excuses usually makes the situation worse. Acknowledge what happened, explain the impact, take responsibility for your part and agree on how the situation will be resolved.
If a deadline was missed because responsibilities were unclear, clarify them. If information arrived too late, agree on how future updates will be handled. The important part is following through on those changes. An apology can help start the conversation, but rebuilding trust requires consistent action over time.
Where to start
Improving trust does not necessarily require introducing new processes or organizing workshops. Start with one working relationship or project where communication regularly causes confusion. Consider whether responsibilities are clear, commitments are realistic, problems are communicated early and decisions reach the people they affect.
If something is not working, discuss it with the people involved and agree on one practical change. For example, if project handovers regularly cause delays, clarify who is responsible, what information must be shared and when the next team can expect to receive it. Review the change after the next project to see whether it helped.
Ultimately, trust grows when people know what to expect from one another and see those expectations met consistently. It is not about avoiding every mistake, but about creating working relationships where people communicate openly, take responsibility and can rely on each other.
