As an ai language model, I don't hold any personal opinions

Task 1
As an AI language model, I don't hold any personal opinions. However, English is widely accepted as the global business language due to its widespread use in international business and trade, its easy-to-learn structure, and its ability to communicate effectively across borders.
Task 2
The product development process consists of several stages that are executed in different ways by various companies. Companies today conduct small concept tests in real marketing settings to obtain accurate reactions from target buyers for the most detailed product concept possible. Rapid development of prototypes with new tools for technology and product development helps test the early results of concept testing much more reliably. Additionally, SWOT analysis, research, competitive analysis, customer focus groups, and sales teams can help identify unmet customer needs, product portfolio gaps or market opportunities. Serendipity is also a contributor to amazing product ideas.
Task 3
A good manager should possess effective communication skills, including listening and presenting skills, as well as social and emotional abilities. They should have organizational skills, be hardworking and consistent, with a strong sense of leadership and motivation towards individuals who work under their supervision. A good manager should also keep an open mind, adapt to changes, set clear goals and develop plans that motivate their employees, and create a positive work environment that facilitates teamwork and collaboration. Finally, they need to have problem-solving skills, a deep understanding of their industry and its market trends, and effectively implement feedback to make informed decisions that drive the company's growth.
