An Initial Analysis of a Laboratory Activity Resulted in the First

question 12

Essay

An initial analysis of a laboratory activity resulted in the first table below. After this analysis, the managers determined that their element descriptions were not as accurate as they should have been-they had left out an element, underestimated a distance, and understated the need for accuracy. They revised the table of element data, which appears in the second table. $\begin{array}{|l|c|c|}\hline {\text { Original Activity: Pouring tube specimen }} \\\hline {\text { Element description }} & \text { Element code } & \text { TMU } \\\hline \text { Get tube from rack } & \text { AA2 } & 35 \\\hline \text { Get stopper, place on counter } & \text { AA2 } & 35 \\\hline \text { Get centrifuge, place at sample tube } & \text { AD2 } & 45 \\\hline \text { Pour (3 sec.) } & \text { PT } & 83 \\\hline \text { Place tubes in rack (simo) } & \text { PC2 } & \underline{40} \\\hline \text { TOTAL TMU } & & \\\hline\end{array}$

$\begin{array}{|l|c|c|}\hline {\text { Revised Activity: Pouring tube specimen }} \\\hline {\text { Element description }} & \text { Element code } & \text { TMU } \\\hline \text { Get tube from rack } & \text { AC3 } & 70 \\\hline \text { Get stopper, place on counter } & \text { AA2 } & 35 \\\hline \text { Get centrifuge, place at sample tube } & \text { AD2 } & 45 \\\hline \text { Pour (3 sec.) } & \text { PT } & 83 \\\hline \text { Get stopper, place on tube } & \text { AC1 } & 40 \\\hline \text { Place tubes in rack (simo) } & \text { PC2 } & \underline{40} \\\hline \text { TOTAL TMU } & & \\\hline\end{array}$ Calculate the total standard minutes for the original activity "pouring tube specimen." Calculate the total standard minutes for the revised activity "pouring tube specimen." What is the increase, in seconds, from the first version to the second?
