The plain-words read of this example
The work needs 187 labor hours, so 4 workers at 8.0 hours a day, 5 days a week, take about 5.8 workdays (1.2 weeks) and miss the 1.0 week target. Labor costs about $12,693.33 at straight time. The smallest crew that meets the date is 5 workers; the cheapest option that meets it: 5 workers at 8.0 h, 5 days: $12,693.33. So far the crew runs at 0.0417 LH a unit against 0.0389 planned, which forecasts 200 LH at completion against 180 in the estimate. Long weeks cost output as well as pay, so treat overtime as a short-term fix.
