Know your audience
When speaking to people, make sure you understand what their technical background is. A non-technical person will not understand deeply technical problems and a technical person may not care for business needs. Don’t go into too much low-level details with business stakeholders, but go into deep and precise technical jargon when speaking to fellow engineers.
Make sure to ask the person(s) you are talking to if they already understand a certain subject. There is no point in going into details they already understand.
Establish Relevance First
In order to capture the attention of the listener, make sure to describe how the information you are about to describe relates to them.
Use analogies and storytelling
When explaining highly technical problems to non-technical people, use analogies. For example you can correlate Load Balancing with a hostess working at a restaurant that seats people to create order and balance the work of the servers. People learn and understand better when they hear an interesting analogy or story.
Simplify
Break down complex tasks into tangiable action items. Simplicity is always good. Complex topics without any organization and guidance from the architect or Team Lead may be easily misunderstood.
This also empowers developers to implement a solution in a way that they think is best.
Leverage Visual Aids
You can accompany your explanations with diagrams, presentations, flowcharts or models. This will capture the attention of your audience.
This way you are using two of their senses for learning.
Check for understanding
Periodically ask if your audience understood what you are talking about.
