What is the REFA calculating method or mathematics?

The REFA calculating method is essentially a structured approach to analyzing work processes using precise mathematical and statistical techniques. It involves breaking down tasks, measuring time, and using data to optimize efficiency and productivity. Here's a deeper look at the methodology and the mathematics behind it:

Steps in REFA Calculating Method

1.Time Studies:

1a. Measurement: Use stopwatches or digital timers to measure the time taken for each task.

1b. Data Recording: Record times in detail, noting start and stop points for each task.

2. Data Analysis:

2a. Statistical Methods: Apply statistical tools to analyze the collected data, identifying average times, variations, and trends.

2b. Frequency Distribution: Determine how often specific time durations occur to understand performance patterns.
