Time and Work is also called schedule factor, Compressed workweek schedule, or time and motion study. Time and Work is a part of work-study or work analysis.
The people working under a project or in a company need to submit their work; at their place of duty, they have to do their work regularly. This period is fixed; they can’t change it. But the company needs to know how much time they can spend to complete the work. There is no direct answer to this problem, so we need some formula to solve this type of time and work question.
About Time
Human life is divided into years, months, weeks, days, hours, minutes, and seconds that represent units of measure on earth where they live.
The time is divided into 12 equal parts representing units of measure of 24 hours called day. Each hour may be divided into 60 equal minutes and each minute into 60 equal seconds. So the division of time is done as follows:
1 day = 1 hour x 24 minutes x 60 seconds = 86400 Seconds
1 Hour = 60 Minutes = 3600 Seconds
1 Minute= 60 Seconds = 60000 Milliseconds.
About Work
The whole point of the time and work questions is how much work you can do in a given period. The time and work formula say that
Work is the total of each piece of work done by an employee in a day or a week.
Work = Total pieces of work done by employee per day or week
Work can be defined as the total amount of work done by an employee in one week. It is the total of all the individual pieces of work a person can do within a week.
Work = Total pieces of work done by employee per day or week
Work = Total hours spent on works per day or week
If a person works 3 days a week, their total score will be 3 x 7.5 = 22.5 hours per week. This formula calculates the time to complete the project, called the Time and Work formula.
Types of Time and Work Questions
- Taking time with respect to time.
- Work with respect to time
- Total time and work
- The number of hours per week/ hours per day.
- Time and work with respect to the number of employees.
- Total time spent by the employee at his place of duty daily.
- The number of days of absence from work.
- The total number of hours of work.
- Total time with respect to total pieces of work.
- Addition of two time and work questions.
- Different ways of calculating time.
- Work formula in a project with respect to the number of hours per day or week.
Time and Work Questions Examples
- A person’s work consists of a hundred different activities, each requiring one hour to complete. Assuming the person works on average two hours per day, how many days in a week are eligible for his work?
The answer is: 1
Reason: The answer is given in the question that there are a hundred different activities, each requiring one hour to complete, and the person works on average two hours per day. Hence, it is clear that he does not complete all the activities within each day’s time. Hence we cannot use the total formula for this problem. We cannot say that number of days = total hours/number of hours in a day = (100/2) = 50 days.
- The Boss is looking to assign time and work to an employee whose base pay is 1000 with the understanding that the employee will be paid 0.50 per hour in addition to his base pay.
For example, Qty = 5000 units
Number of hours in a week = 5000 / 60,000 = 0.2 or 20 hours
The total annual rate of pay for the employee = 5000 x 1000 = 50,000
The total yearly salary for the employee = (Total annual rate of pay) + (base salary)
Hence total yearly salary for an employee with the base salary of 1000 and the annual rate of 50,000 is: 50,000 + (base salary) – 1000
Time and Work Relativity
Time and work is the most important topic of project management. The time and work formula is used to calculate the time taken by an employee to complete their work while solving time and work questions. This formula depends on the employee attendance, holidays, absence, etc.
The formula of work with respect to time:
Work done = Time taken x Rate of work
Here is the Time and Work formula with respect to time.
It is called the standard time and work formula:
Work = Total hours worked per day or week
Accelerated Work: The formula can also be calculated by the acceleration factor.
Conclusion
The topic of time and work is a very important one. When it comes to time measurement, you need to be accurate. When solving time and work questions related to time and work formulas, you must remember the restrictions and rules. The total hours per day or week is very important as this is the only key that will help you solve other problems in this section. You need to understand this section well before solving time and work questions. If you want to solve time and work questions properly, you need to practice a lot.
