In order of most following tasks. Tiebreaker: greatest positional weight. (Use your rounded cycle time. Enter your tasks in the order they were assigned at each station as a letter between a and h in lowercase with no other text or symbols. Round your numerical answers to 1 decimal place.) What is Efficiency? (Use your rounded cycle time in the denominator of your efficiency calculation. Round your answer to 1 decimal place.) b. In order of greatest positional weight. Tiebreaker: most following tasks. (Use your rounded cycle time. Enter your tasks in the order they were assigned at each station as a letter between a and h in lowercase with no other text or symbols. Round your numerical answers to 1 decimal place.) What is Efficiency? (Use your rounded cycle time in the denominator of your efficiency calculation. Round your answer to 1 decimal place.)
