One of the hardest things to build in a team is a deep and lasting sense of trust. There are many ways to go about it, but one that I have consistently found to be the most effective is to invest time in providing context.
Context is such a powerful tool. It allows a person to understand the assumptions and system dynamics involved in a decision. In doing so, you build trust that the decision to do A over B was done thoroughly and thoughtfully. It lifts the fog of war and shows the path to which you arrived at the final destination. By doing so, you eliminate any ambiguity in the process
Whenever possible, I try to invest in providing the context for a request, a question, or decision. The larger the decision, the more impactful the context can be, but even simple and small requests with context go a long way in building trust with an individual or team. By doing this when things are going well and there is the time to do so, you pave the relationship with trust and understanding.
This then enables you with the ability to omit context when you have to; when there is urgency and a necessity to move fast and execute. Since you took the time in prior decisions to explain the context, you have built the confidence, trust, and understanding that decisions are done with thoughtfulness. Only with that trust equity built up over time can you do this effectively.
Doing this has also honed my own framework for decisions as it is harder to articulate the decision and the reasoning behind a decision than to just explain the decision itself. This is one of the reasons I developed lenses as they help me articulate context more effectively.
