Dear Student,
Every business organisation has its own planning, organising, staffing, directing and controlling functions of management that may differs from one organisation to another organisation. While characteristics of management are universal in nature.
Same in the case of Pool club restaurant and Steel plant, their will be difference in the planning, controlling, staffing, directing function, as one might appoint fresh workers while another one might need experienced to work with them. One might make single use plans while other may focus on standing plans. While characteristic of management are same in both cases.
Regards,
