Ch10. Management in Practice — Key Review for Job Exams and Interviews

Purpose of This Lecture

Having worked through nine lectures in the Management Essentials series, this final lecture is your direct toolkit for job exams and interviews. It covers the question types and answer strategies that actually appear in business management written tests and interviews.

Compressed Review of Core Series Concepts

The 4 Management Functions (Ch1)

Function	Key Content
Planning	Goal setting, SMART criteria
Organizing	Division of labor, span of control, line-and-staff
Leading	Motivation, leadership styles
Controlling	Performance measurement, feedback, correction

Strategic Management Essentials (Ch2)

SWOT: Internal (Strengths/Weaknesses) + External (Opportunities/Threats) → SO/ST/WO/WT strategies
Porter’s Generic Strategies: Cost Leadership / Differentiation / Focus
BCG Matrix: Stars (high growth, high share) / Cash Cows (low growth, high share) / Question Marks / Dogs

Motivation Theories (Ch3)

Maslow: Physiological → Safety → Social → Esteem → Self-Actualization (hierarchical)
Herzberg: Hygiene factors (remove dissatisfaction) / Motivators (create motivation)
McGregor: Theory X (control-based) / Theory Y (autonomy-based)
Vroom’s Expectancy Theory: Motivation = Expectancy × Instrumentality × Valence

Human Resource Management (Ch4)

Job analysis → Recruitment (structured interviews) → Training (OJT/Off-JT) → Performance appraisal (MBO, 360-degree) → Compensation

Financial Ratios (Ch5)

Ratio Group	Key Ratios
Profitability	ROE, ROA, Operating Margin
Safety/Leverage	Debt-to-Equity, Current Ratio, Interest Coverage
Activity	Inventory Turnover, Accounts Receivable Turnover
Growth	Revenue Growth Rate, Operating Income Growth Rate

Operations and Quality (Ch6)

PDCA: Plan → Do → Check → Act
Six Sigma DMAIC: Define → Measure → Analyze → Improve → Control
Lean’s 7 Wastes: TIMWOOD (Transportation, Inventory, Motion, Waiting, Overproduction, Over-processing, Defects)

Public Enterprises (Ch7)

Categories: Market-type / Quasi-market-type / Fund management / Entrusted execution
Performance evaluation: S through E rating; social value criteria strengthened
ESG: E (Environmental) · S (Social) · G (Governance)

Accounting (Ch8)

BEP = Fixed Costs ÷ (Unit Price − Variable Cost)
ROE = Net Profit Margin × Asset Turnover × Financial Leverage (DuPont formula)
Financial vs. Managerial Accounting: External reporting vs. internal decision-making

Management Science (Ch9)

EMV = Σ (Outcome × Probability)
LP: Optimize an objective function subject to constraints
PERT/CPM: Critical Path, Slack time

Common Question Type Analysis

Type 1: Concept Matching

“Which of the following does NOT belong to Porter’s Generic Strategies?” → Memorize Cost Leadership, Differentiation, and Focus; distinguish from trap choices (Innovation Strategy, Growth Strategy)

Type 2: Theory Identification from a Scenario

“Manager Kim believes team members will solve difficult tasks on their own and grants them autonomy. Which theory applies?” → McGregor’s Theory Y; connect to Herzberg’s Motivators (autonomy)

Type 3: Calculation

“Fixed costs: $200,000; Selling price per unit:$ 50; Variable cost per unit: $30. What is the break-even quantity?" →$ 200,000 ÷ ( $50 −$ 30) = 10,000 units

Type 4: Case → Technique Matching

“XYZ Corp analyzed the 8 steps of its production process and eliminated 2 unnecessary waiting steps. What technique is this?” → Lean Manufacturing / Elimination of the 7 Wastes

Type 5: Understanding Public Enterprise Characteristics

“Why do public enterprises maintain lower service prices than private companies?” → Public interest objectives, natural monopoly regulation, support for economically vulnerable populations

Interview Answer Framework: Applying Management Concepts

Management knowledge is used in interviews either as a direct answer or as supporting rationale.

Interview Question Types and Applicable Concepts

“How would you strengthen this organization’s competitiveness?” → Porter’s Differentiation Strategy or Resource-Based View (core competencies) → “Looking at the organization’s key strength — [X capability] — through the VRIN lens, it is rare and difficult to imitate, therefore…”

“How would you handle a conflict with a team member?” → Thomas-Kilmann Conflict Mode: Collaborating strategy → “I would identify both parties’ underlying interests and use principled negotiation to…”

“Can you describe an experience where you improved a process?” → Structure your answer using PDCA or Six Sigma DMAIC → “I defined the problem (D), measured the current state (M), analyzed root causes (A), developed improvements (I), and standardized the solution (C).”

“Why did you apply to a public organization?” → Public interest and social value + ESG context → “In areas where private markets fail to provide adequate supply…”

Complementary Series Worth Studying

Pairs well with the Management Essentials series:

Workforce Competencies Fundamentals: Job performance competencies in professional certification exams (communication, numeracy, problem-solving, etc.)
Economics Essentials: Interpreting macroeconomic indicators, fiscal and monetary policy
Business Writing: Reports, memos, professional documentation skills
Employment Law Basics: Labor Standards Act, employee rights, workplace regulations

Key Concept Cards

ERP (Enterprise Resource Planning) ★★★★ : A system that connects all business functions (production, sales, finance, HR) through a single integrated database. Supports real-time information sharing and decision-making. Leading products: SAP, Oracle. Benefit: eliminates information silos between departments. Drawback: high implementation cost and difficult customization.

CRM (Customer Relationship Management) ★★★ : Maximizes revenue and customer relationships through data collection and analysis. Goal is to maximize Customer Lifetime Value (CLV). Operational CRM (automation and service) + Analytical CRM (data mining) + Collaborative CRM (channel integration).

Practice Quiz

Q. Distinguish what ERP, SCM, and CRM each manage.

ERP: all internal corporate resources (integrates production, finance, HR). SCM: the entire cross-company supply chain (from raw materials to end consumers). CRM: customer relationships (marketing, sales, service).
