Chartered Engineer (CEng) Competence C: Responsibility, Management and Leadership Flashcards

24 sample cards from the Competence C: Responsibility, Management and Leadership deck

Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.

1. What is a force field analysis (Lewin) used for in managing change?

   A technique that maps the driving forces pushing for change against the restraining forces resisting it; change is achieved by strengthening drivers and/or weakening restrainers.

2. What does it mean to exercise 'sound engineering judgement'?

   Making reasoned decisions by integrating technical knowledge, experience, codes/standards, risk and uncertainty, ethical and commercial factors, and recognising the limits of one's competence — especially where data is incomplete.

3. What is the role of professional codes of conduct in engineering judgement?

   They set ethical and professional obligations (e.g. holding paramount the safety and wellbeing of the public, acting with integrity and within competence) that must frame and constrain technical and commercial decisions.

4. What is a factor of safety, and why is it applied in engineering decisions?

   $$\text{Factor of Safety} = \frac{\text{Ultimate (or yield) capacity}}{\text{Actual applied load (working stress)}}$$ It provides a margin against uncertainty in loads, materials and analysis, ensuring safe, judgement-informed design.

5. What is the difference between fixed costs and variable costs?

   Fixed costs remain constant regardless of output volume (e.g. rent, salaries); variable costs change in direct proportion to output (e.g. materials, energy per unit). Total cost = fixed + variable.

6. What is the break-even point and its formula?

   The output level at which total revenue equals total cost (zero profit). $$\text{Break-even units} = \frac{\text{Fixed Costs}}{\text{Selling Price} - \text{Variable Cost per unit}}$$ The denominator is the unit contribution margin.

7. What is contribution margin?

   The amount each unit sold contributes to covering fixed costs and profit. $$\text{Contribution} = \text{Selling Price} - \text{Variable Cost per unit}$$ Total contribution must exceed fixed costs to make a profit.

8. Define Net Present Value (NPV) and its decision rule.

   $$NPV = \sum_{t=0}^{n} \frac{C_t}{(1+r)^{t}}$$ where $C_t$ is net cash flow in year $t$ and $r$ the discount rate. Accept the project if $NPV > 0$ (value created); reject if $NPV < 0$.

9. What is the Internal Rate of Return (IRR)?

   The discount rate $r$ at which a project's NPV equals zero ($\sum \frac{C_t}{(1+r)^t} = 0$). A project is acceptable if its IRR exceeds the required rate of return (hurdle rate / cost of capital).

10. How is simple payback period calculated, and what is its main limitation?

    $$\text{Payback} = \frac{\text{Initial Investment}}{\text{Annual Net Cash Inflow}}$$ It measures how long to recover the outlay but ignores the time value of money and cash flows after payback.

11. Define Return on Investment (ROI).

    $$ROI = \frac{\text{Net Profit (Gain - Cost)}}{\text{Cost of Investment}} \times 100\%$$ A profitability ratio expressing the return generated relative to the amount invested.

12. What is depreciation, and name two common methods.

    The systematic allocation of an asset's cost over its useful life. Straight-line: $\frac{\text{Cost} - \text{Salvage}}{\text{Useful life}}$ per year; Reducing (declining) balance: a fixed percentage applied to the remaining book value each year.

13. What is the difference between capital expenditure (CapEx) and operating expenditure (OpEx)?

    CapEx is spending on long-term assets capitalised on the balance sheet and depreciated over time (e.g. plant, equipment); OpEx is day-to-day running cost expensed in the period incurred (e.g. wages, utilities).

14. What is whole-life (life-cycle) costing?

    Evaluating the total cost of an asset over its entire life — acquisition, operation, maintenance, and disposal — rather than just initial purchase price, to inform value-for-money engineering and procurement decisions.

15. What is gross profit margin and how does it differ from net profit margin?

    $$\text{Gross Margin} = \frac{\text{Revenue} - \text{COGS}}{\text{Revenue}} \times 100\%$$ It covers direct costs only; net profit margin subtracts all costs (overheads, interest, tax) and reflects overall profitability.

16. What is cash flow, and why can a profitable business still fail because of it?

    Cash flow is the net movement of cash in and out over a period. A profitable business (profit on paper) can fail if cash is tied up in receivables/stock and it cannot meet short-term obligations — i.e. it becomes illiquid/insolvent.

17. In financial terms, what is working capital?

    $$\text{Working Capital} = \text{Current Assets} - \text{Current Liabilities}$$ It measures short-term liquidity — the funds available to meet day-to-day operational obligations.

18. What does accountability for decisions and outcomes require of a chartered engineer?

    Owning the consequences of decisions, being answerable to stakeholders, maintaining transparent records and audit trails, learning from failures, and not deflecting responsibility for outcomes within one's remit.

19. What is a RACI matrix and what do its letters mean?

    A responsibility assignment chart clarifying roles for each task: Responsible (does the work), Accountable (ultimately answerable — only one per task), Consulted (gives input), and Informed (kept updated).

20. What is the difference between governance and management in delivering engineering work?

    Governance sets direction, defines authority/decision rights, and provides oversight and assurance that objectives and standards are met; management executes within that framework, planning and controlling day-to-day delivery.

21. What is a 'lessons learned' (post-implementation) review and why is it important for accountability?

    A structured retrospective after a project or phase capturing what went well and what did not, and why, so the organisation improves future performance and demonstrates accountability through continuous learning.

22. What is a stakeholder, and how does a power/interest grid help manage them?

    A stakeholder is any party affected by or able to affect the work. The power/interest grid classifies them into Manage Closely (high power, high interest), Keep Satisfied (high power, low interest), Keep Informed (low power, high interest), and Monitor (low power, low interest).

23. What is the duty of care a chartered engineer owes, and to whom?

    A legal and professional obligation to exercise reasonable skill and care to avoid foreseeable harm — owed primarily to the public (whose safety and wellbeing is paramount), and also to clients, employers, colleagues and the environment.

24. What is delegation's benefit-risk trade-off a leader must judge?

    Delegation develops staff, increases capacity and frees the leader for higher-value work, but risks task failure if competence is misjudged; the leader matches task complexity to delegatee capability and provides appropriate support and monitoring.
