Step 1: Management methods in health administration split into two groups: behavioural science methods and quantitative methods.
Step 2: The behavioural science group includes organizational design, personnel management, management by objectives (MBO), information systems, and communication.
Step 3: The quantitative group includes cost-benefit analysis, cost-effective analysis, input-output analysis, network analysis (PERT and CPM), planning-programming-budgeting systems, and decision making.
Conclusion: Of the options, only management by objectives belongs to the behavioural science group. Network analysis, systems analysis, and decision making are quantitative tools.
