One of the most critical things that an engineer or technical leader can do for their career is to practice and develop strong communication skills. It is appealing to many people to spend their entire career in the technical quadrant (and it can be fulfilling). However, being able to step outside of it is valuable and provides the opportunity to significantly increase impact and recognition.
The top left quadrant is where engineers and technical leaders focus their technical skills and expertise. They are often very good at solving complex problems and developing innovative solutions. However, they may not be as good at communicating their ideas to others, or at understanding the needs of non-technical stakeholders.
Being able to step outside of that quadrant and communicate effectively with others is a valuable skill. It allows engineers and technical leaders to share their ideas with a wider audience, and to get buy-in from stakeholders who may not have a technical background. It also allows them to understand the needs of their customers and users, and to develop solutions that meet those needs.
If you are an engineer or technical leader, I encourage you to develop your communication skills. It is an investment that will pay off in the long run.
