a) This question actually involves the issue of human resources. Many SMEs and business start-ups have such a misunderstanding: hoping all employees could bring motivation and creativity for the enterprises. In reality, different staff will discharge different roles in the enterprise. Imagine, all employees are motivated, creative, want to be a leader, then who are followers or executors?
b) Moreover, the original objective of this project is to strengthen the human resources for the SMEs and business start-ups and not to replace the management and core staff of the enterprise (they are responsible for the motivation and creativity of the enterprise). The role of the elderly persons is of the supplemental nature which is a steady work force. The elderly persons will not replace them, and more importantly, they will assist the management and core staff to enhance the experience and technology.
