Imagine, you're a regional manager in a software solutions company. The CEO asks you to take the lead in a task force evaluating potential green energy investments. While you understand that it's a case of the company diversifying, you also understand that you know nothing about investing in green energy. As the confusion and fear of failure start settling in, you start confronting yourself with the concept of the "Circle of Competence".
Coined by Warren Buffett, the "Circle of Competence" is a concept where you draw a boundary around areas or fields you understand well and have a track of successful decision making. This boundary encompasses your accumulated knowledge and experience, measuring your expertise. For Buffett, it's his way of identifying which investment possibilities he should consider and which ones he should avoid.
Understand that the Circle of Competence doesn't limit you but shields you from potential professional mishaps. Knowing your Circle allows you to remain confident, take on tasks suited for your skills and make a consistent successful impact, while also helping you tactically expand your knowledge areas. You might not know everything, but you can ensure that what you do know is solid, and what you don't, you learn systematically.
A newly assigned project manager is given the task of handling an Artificial Intelligence-based project, a field he doesn't have much knowledge of. The best way to handle this situation would be to:
Step back and allow someone else with the right expertise to take over the project.
Continue managing the project and learn about AI during the process.
