The Right Fit for Business Development
A business developer can be the business owner(s), or the designated employee(s) working in business development. Anyone who can make or suggest a strategic business change for a value-add to the business can contribute towards business development. Businesses often encourage employees to come up with innovative ideas, which can help in improving the overall business potential.
Businesses also seek help from external incubator firms, business development companies (BDC) and small business development centers (SBDC). However, these entities assist in business establishment and the necessary fine-tuning only during the early stages of business setup. As a business matures, it should aim to build its business development expertise internally.
