- Anecdotally, entrepreneurs frequently encounter two critical dilemmas in managing human resources: the timing of hiring and the decision regarding hiring a generalist versus a specialist for their growing venture. Deciding when to expand a team is crucial, as premature hiring (i.e., hiring too soon) can strain resources, while delayed hiring (i.e., hiring too late) might hinder growth opportunities. Moreover, the choice between hiring a generalist or a specialist depends on the specific needs and stage of the venture, with each option presenting distinct advantages and challenges. To address these issues, a management scholar seeks to identify the factors shaping the hiring cycle throughout the entrepreneurial journey and to understand the criteria for choosing between generalists and specialists at various stages of a venture.
