Nature and Scope of Management
What management is
Management is the process of planning, organising, leading and controlling the resources of an organisation - people, money, materials, information and time - so that stated objectives are met. Questions in this domain test definitions, the efficiency/effectiveness distinction, managerial levels and Mintzberg's roles rather than abstract theory.
Efficiency versus effectiveness
Efficiency is doing things right: the ratio of outputs to inputs, a cost and waste focus. Effectiveness is doing the right things: choosing goals that fit the environment and reaching them. An organisation can score highly on one and fail on the other, and the distinction is the most examined idea here.
Levels, skills and roles
- Top management sets direction and strategy; conceptual skill dominates.
- Middle management converts strategy into functional and departmental plans.
- First-line management supervises daily operations; technical and human skills dominate.
Katz's three skills - technical, human, conceptual - are tested as a matching question: technical matters most at the bottom, conceptual at the top, human skill at every level. Mintzberg's ten roles cluster into interpersonal (figurehead, leader, liaison), informational (monitor, disseminator, spokesperson) and decisional (entrepreneur, disturbance handler, resource allocator, negotiator).
Worked example
A bakery installs a faster oven, cutting cost per loaf from ₦120 to ₦95, while demand shifts to wholemeal and white loaves pile up unsold. Reasoning: input cost per unit fell, so efficiency improved; output no longer matched customer need, so effectiveness fell. The managerial fix is a product-mix decision, not a cheaper oven - which is why effectiveness is judged first and efficiency second.
Traps that cost marks
- Using efficiency and effectiveness interchangeably.
- Placing all of Mintzberg's roles in the decisional cluster.
- Calling management a fully fledged profession: unlike law or medicine it has no single enforced licence to practise.
- Assuming one universally best way to manage - that is the contingency insight, not the classical one.
