National Exams — December 2017 — 11-CS-4 Engineering Management. Closed book; no calculators. Any five questions constitute a complete paper; all questions are of equal value (20 marks each). Seven questions are set; full worked answers to all seven (Questions 1–7) are given below.

(a) McGregor's Theory X and Theory Y describe two contrasting sets of managerial assumptions about people. Theory X assumes the average worker inherently dislikes work, avoids responsibility, and must be coerced, controlled, and directed—justifying an authoritarian, tightly supervised style. Theory Y assumes work is as natural as play, that people will exercise self-direction and seek responsibility when committed to objectives, and that they possess untapped creativity—justifying a participative, empowering style. McGregor argued that Theory Y assumptions generally release far more human potential. (b) Maslow's Hierarchy of Human Needs arranges needs in five ascending levels—physiological, safety, social (belonging), esteem, and self-actualization—and holds that a person is motivated by the lowest unmet level; once a need is largely satisfied it no longer motivates, and attention shifts upward. (c) Herzberg's Motivator–Hygiene (two-factor) concept separates job factors into two groups. Hygiene factors—pay, company policy, working conditions, supervision, security—cause dissatisfaction when deficient but do not create satisfaction when present. Motivators—achievement, recognition, the work itself, responsibility, advancement—are what genuinely generate satisfaction and effort. Herzberg's insight, refining Maslow, is that removing dissatisfaction is not the same as creating motivation; true motivation requires enriching the work itself.
B. F. Skinner's operant conditioning holds that behaviour is shaped by its consequences: behaviour followed by favourable consequences tends to be repeated, while behaviour followed by unfavourable consequences tends to diminish. In the workplace this is applied as organizational behaviour modification through four types of consequence. Positive reinforcement follows a desired behaviour with a pleasant consequence—praise, a bonus, recognition—thereby strengthening and increasing that behaviour; it is the most effective and lasting motivator. Negative reinforcement strengthens a desired behaviour by removing an unpleasant condition when the behaviour occurs—for example, ending close scrutiny once an employee consistently meets standards; note that, like positive reinforcement, it increases the desired behaviour, by relief rather than reward. Punishment applies an unpleasant consequence to reduce an undesired behaviour, and extinction withholds reinforcement so a behaviour fades. For motivating employees, Skinner's practical lessons are to reinforce desired behaviours promptly and specifically, to favour positive reinforcement over punishment (which breeds resentment and only suppresses behaviour temporarily), and to make the link between performance and consequence clear and consistent.
Drawing on Likert's research, (a) a high-producing organization is characterized by supportive relationships, high mutual trust and confidence, open communication in all directions, genuine employee participation in goal-setting and decision making, effective teamwork, and motivation through commitment rather than fear; it corresponds to Likert's participative System 4 and tends to sustain superior long-term performance. (b) A low-producing organization displays the opposite: distrust and fear, one-way downward communication, imposed goals, little participation, and motivation by threat or pressure; it corresponds to the exploitative or benevolent-authoritative Systems 1 and 2 and tends to suffer low morale, high turnover, and mediocre results. (c) High-producing managers are those whose units consistently achieve superior results; research associates them with an employee-centred rather than purely job-centred style—they build supportive relationships, set high but attainable goals, communicate openly, delegate and empower, coach and develop their people, and hold themselves and their teams accountable. They combine genuine concern for people with a firm focus on performance, creating the participative climate that high-producing organizations require.
An engineering manager would adopt Theory Y assumptions with a skilled professional team, satisfying their basic pay and security needs (hygiene) while providing the recognition, responsibility, and challenging work that genuinely motivate (Herzberg, Maslow's higher needs). Applying Skinner, she would reinforce good performance promptly with specific praise rather than relying on criticism, and by cultivating trust, open communication, and participation she would move her unit toward the high-producing System 4 climate.
