Efficiency and Effectiveness of an Organisation
Jaap de Jonge, Editor, Netherlands
I would say the overall efficiency and effectiveness of an organisation depends on the 7 S-es of McKinsey
When talking about on who it depends inside the organization, I would say on all employees, managers, leaders and directors.
Note that external persons and parties like customers, suppliers, organizations and governments can also influence the efficiency and effectiveness of an organisation. See stakeholder analysis
