Maharashtra HSC Employability Skills (Technical) cheat sheet

Communication process has six elements: sender, message, encoding, channel, receiver, feedback; noise can distort any stage.

7 C's of effective communication: Clear, Concise, Concrete, Correct, Coherent, Complete, Courteous.

Barriers split into physical (noise, distance), semantic (jargon, ambiguity), psychological (prejudice, emotion) and organisational (hierarchy, overload).

Active listening ratio rule: listening should occupy roughly 45% of communication time, speaking 30%, reading 16%, writing 9%.

Formal channels are vertical (downward, upward) and horizontal (lateral); informal channel is the grapevine, fastest but least accurate.

Feedback is the only element that confirms the message was decoded as intended; absence of feedback means communication is incomplete.

Non-verbal cues (kinesics, proxemics, paralanguage, chronemics) carry more weight than words when the two conflict.

In technical writing, prefer active voice, short sentences (average 15-20 words) and one idea per paragraph.

SMART goals: Specific, Measurable, Achievable, Relevant, Time-bound; a goal missing any attribute is not verifiable.

Eisenhower matrix sorts tasks by urgency and importance into four quadrants; quadrant 1 do now, quadrant 2 schedule, quadrant 3 delegate, quadrant 4 eliminate.

Pareto principle: roughly 80% of results come from 20% of tasks, so priority ranking beats equal effort distribution.

Time management tools: to-do list, daily planner, Gantt chart for project tasks; Parkinson's law states work expands to fill the time available.

Stress response stages follow the general adaptation syndrome: alarm, resistance, exhaustion.

Emotional intelligence has five components: self-awareness, self-regulation, motivation, empathy, social skills.

Pomodoro technique: 25 minutes focused work plus 5 minutes break, with a longer break after four cycles.

Self-motivation cycle: need, drive, goal-directed behaviour, achievement, new need; intrinsic motivation persists longer than extrinsic rewards.

Hardware is physical equipment; software is divided into system software (OS, utilities) and application software (word processor, spreadsheet).

Common file extensions: .docx word processing, .xlsx spreadsheet, .pptx presentation, .pdf portable document, .jpg/.png images, .mp4 video.

Spreadsheet cell reference combines column letter and row number (A1); a formula always begins with '=' and functions with a name such as =SUM(A1:A10).

Keyboard shortcuts: Ctrl+C copy, Ctrl+X cut, Ctrl+V paste, Ctrl+Z undo, Ctrl+Y redo, Ctrl+S save, Ctrl+P print, Ctrl+F find.

An email address structure is local-part@domain, e.g. [email protected]; 'To' is primary recipient, 'Cc' visible copy, 'Bcc' hidden copy.

Internet basics: URL identifies a resource, HTTP/HTTPS is the transfer protocol, HTTPS encrypts traffic with TLS; a browser renders HTML.

Strong password rule: minimum 8-12 characters mixing upper case, lower case, digits and symbols, never reused across accounts.

Digital safety: phishing messages create urgency and mismatched sender domains; verify the domain before clicking links or sharing OTPs.

Entrepreneur functions: idea generation, opportunity assessment, resource mobilisation, risk bearing, innovation and management of the venture.

Types by scale and intent: small business owner, scalable startup, social entrepreneur, intrapreneur operating inside an existing firm.

Business plan sections: executive summary, market analysis, product or service description, marketing plan, operations plan, management team, financial plan.

Break-even point in units = fixed costs / (selling price per unit - variable cost per unit).

SWOT analysis maps internal Strengths and Weaknesses against external Opportunities and Threats; it is a decision aid, not a strategy.

Market segmentation bases: geographic, demographic, psychographic and behavioural; a target segment must be measurable, accessible and profitable.

Sources of finance split into equity (ownership dilution, no repayment) and debt (interest, fixed repayment, no dilution).

Intellectual property types: patent (invention, up to 20 years), trademark (brand sign), copyright (creative work), industrial design (appearance).

Sustainability rests on three pillars: environmental, economic and social; a solution is sustainable only when all three hold.

Renewable sources: solar, wind, hydro, biomass, geothermal; non-renewable: coal, petroleum, natural gas, nuclear fuel.

3 R hierarchy in order of preference: Reduce, Reuse, Recycle; reduction avoids waste generation entirely.

Carbon footprint is total greenhouse gas emissions expressed as carbon dioxide equivalent (CO2e) over a defined period or activity.

Energy efficiency means delivering the same output with less energy input; energy conservation means reducing or avoiding the use of energy.

Green jobs are roles that reduce environmental impact, for example solar technician, waste management operator, water treatment operator.

E-waste handling rule: never mix with general waste; route to authorised recyclers because of heavy metals such as lead and mercury.

Environmental management tool ISO 14001 specifies requirements for an environmental management system (EMS) with plan-do-check-act cycle.

Hierarchy of hazard controls, most to least effective: elimination, substitution, engineering controls, administrative controls, personal protective equipment.

Safety signs by shape and colour: red circle with slash prohibition, yellow triangle warning, blue circle mandatory action, green square safe condition or first aid.

PPE selection follows the hazard: helmet for head, goggles or face shield for eyes, ear plugs or muffs above 85 dB, respirator for dust or fumes, gloves matched to chemical.

Fire classes: A solid fuels, B flammable liquids, C gases, D metals, E electrical, F cooking oils; water is forbidden on electrical and oil fires.

PASS method for extinguisher use: Pull the pin, Aim at the base, Squeeze the handle, Sweep side to side.

Electrical safety rule: lock out and tag out before maintenance; never work on a live circuit, and use residual current devices for protection.

First aid basics: RICE for sprains (Rest, Ice, Compression, Elevation); CPR ratio 30 chest compressions to 2 rescue breaths.

5S workplace organisation: Sort, Set in order, Shine, Standardise, Sustain; it underpins housekeeping and accident prevention.

Workplace documents: job card authorises work, work order defines scope, inspection report records conformity, delivery challan accompanies goods.

Precision versus accuracy: precision is repeatability of a measurement, accuracy is closeness to the true value; a gauge can be precise and inaccurate.

Least count of a vernier calliper = 1 main scale division - 1 vernier scale division; for a 0.02 mm calliper, 49 main divisions equal 50 vernier divisions.

Micrometer least count = pitch of screw / number of divisions on thimble; a 0.5 mm pitch with 50 divisions gives 0.01 mm.

Tolerance is the permissible difference between upper and lower limits; clearance fit, interference fit and transition fit describe the resulting assembly.

Housekeeping and 5S support total productive maintenance (TPM); the eight TPM pillars include autonomous and planned maintenance.

Quality tools: check sheet, histogram, Pareto chart, cause-and-effect (fishbone) diagram, control chart, scatter diagram, flowchart.

Technical drawing basics: first-angle projection places the view on the far side of the object, third-angle on the near side; scale is drawing size to real size.

Curriculum vitae sections: personal details, career objective, education, technical skills, projects, experience or internship, achievements, references.

Cover letter structure: sender details, date, recipient, subject line, opening stating the role, body matching skills to requirements, closing with a call to action.

Job interview stages: screening, technical or skills round, HR round; STAR method answers use Situation, Task, Action, Result.
