Communication and Entrepreneurship
This section covers Communication and Entrepreneurship: technical communication in the workplace and the basics of turning an engineering skill into a small enterprise. The exam tests clear messages, documentation and simple business calculations.
Core rules
- Communication is sender → message → channel → receiver → feedback. Barriers include noise, jargon, unclear purpose and assumptions.
- For technical writing, use the 7 Cs: clear, concise, concrete, correct, coherent, complete and courteous. Put the purpose in the subject line and first sentence.
- Active listening means summarising and confirming. In a handover, record machine status, work completed, pending work and safety issues.
- An entrepreneur identifies a problem, surveys demand, estimates costs, prices the product and manages cash. A business plan covers market, operations, finance and risk.
- Break-even quantity = fixed cost/(selling price − variable cost per unit). Contribution per unit is selling price minus variable cost.
Worked example
A workshop has fixed costs of ₹50,000 per month. A bracket sells for ₹200; variable cost is ₹120. Contribution = ₹80. Break-even = 50,000/80 = 625 brackets per month. Selling 700 gives a profit of 75 × ₹80 = ₹6,000, before tax and other costs. Below 625, the workshop makes a loss.
Traps
Do not confuse revenue with profit. Do not treat fixed costs as per-unit costs. Do not send a technical email without a subject, action and deadline. Do not ignore working capital and record-keeping obligations.
