Business acumen is the ability to comprehend the business context, goals, and needs of ML projects. It's essential to have a vision of how ML solutions can add value to clients, employers, and stakeholders, and how to communicate and validate decisions and results. Additionally, you need a strategic mindset that can align ML projects with the bigger picture and long-term objectives. To master business acumen, you should learn the basics of business and management by taking courses, reading books and blogs, watching videos and podcasts, and joining communities and events related to business and management. It's also important to understand your domain and industry by researching and analyzing problems, opportunities, trends, competitors, and customers. Lastly, build your communication and presentation skills by learning how to communicate effectively with different audiences such as technical, business, or general. Utilize tools like storytelling, data visualization, or elevator pitch to convey your message and impact.
