Tools of time management: time norms, peak loads, work curves and rest periods
Four tools help plan time: time norms (how long tasks take), peak loads (busiest periods), work curves (output over time) and rest periods.
The four tools
| Tool | Meaning | How it helps | Home example |
|---|---|---|---|
| Time norms | The usual (average) time needed to finish a task, found by timing it over several days | Makes plans realistic so the day is not over-filled | If sweeping the flat usually takes 15 minutes, plan 15, not 5 |
| Peak loads | Periods when the heaviest load of work comes together | Shows the crunch periods so they can be planned for in advance | Weekday mornings from 6 to 9 am; festival days; when guests arrive |
| Work curves | A graph showing how the rate of work (output) changes during a working period | Shows when efficiency is highest and when rest is needed | Grinding batter speeds up after a few minutes, then slows as the arm tires |
| Rest periods | Planned breaks that let the body and mind recover | Delay fatigue and keep output steady | A five-minute sit-down with water between washing clothes and cooking |
Reading a work curve
A work curve plots output (work done per minute) on the vertical axis against working time on the horizontal axis. It usually shows four parts: a warming-up phase, when output rises as the worker settles into the task; a peak or steady phase of best efficiency; a decline as fatigue sets in; and often a small end spurt, when output rises briefly because the worker knows the task is nearly over. Plan rest periods before the decline begins: short, frequent breaks restore efficiency better than one long break after exhaustion.
Ways to reduce peak loads
- Do pre-preparation the evening before: grind batter, cut vegetables, lay out school uniforms.
- Dovetail tasks: do two things at once, e.g. cut vegetables while dal cooks in the pressure cooker.
- Share the work: children pack their own bags; the husband makes breakfast.
- Use time-saving equipment: pressure cooker, mixer-grinder, washing machine.
- Move flexible tasks, such as ironing or cleaning cupboards, out of the busy period.
- Simplify on busy days: a one-pot meal instead of four separate dishes.
Kinds of rest
Rest works best when it is taken before fatigue builds up.
Time norms run every hostel or hospital kitchen: the time needed to cook a large batch of rice or steam hundreds of idlis decides when cooking must start. The peak load comes just before meal service; pre-preparation the night before and steam cookers spread the load so meals go out hot and on time.
2 marks: “What is a peak load?” The period when the heaviest load of work comes together, e.g. weekday mornings in a working family.
5 marks: “Write a note on work curves and rest periods.” Define the work curve, sketch its four phases (warm-up, peak, decline, end spurt), then explain why short, frequent rests placed before the decline work best.
10 marks: “Discuss the tools of time management. How can peak loads be reduced?” Explain all four tools with a work-curve sketch, then list ways to reduce peak loads with home examples.
The work curve rises, levels, falls, then gives a little kick: warm-up, peak, decline, end spurt. Rest before the fall.
