Waymouth Manufacturing operates a contract manufacturing plant located in Dublin, Ireland. The plant provides a variety of electronics products and components to consumer goods manufacturers around the world. Cycle time is a critical success factor for Waymouth, which has developed a number of measures of manufacturing speed. Waymouth has studied the matter and found that competitive contract manufacturers have manufacturing cycle times $($MCE$)$ of about $36\%.$ When last calculated, Waymouth$$s MCE was $29\%.$

Key measures from the recent month$$s production, averaged over all the jobs during that period, are as follows:

Activity Average Time $($hours$)$

New product development $18\mathrm{.}0$

Materials handling $1\mathrm{.}5$

Order setup $3\mathrm{.}0$

Machine maintenance $3\mathrm{.}5$

Order scheduling $7\mathrm{.}0$

Inspection of completed order $2\mathrm{.}0$

Pack and move to storage or ship $1\mathrm{.}0$

Manufacturing assembly $12\mathrm{.}0$

Order taking and checking $2\mathrm{.}5$

Receiving and stocking raw materials $3\mathrm{.}0$

Inspection of raw materials at start of production $1\mathrm{.}5$

Required:

Determine the manufacturing cycle efficiency $($MCE$)$ for the recent month. $($Round your answer to $1$ decimal place $($i$.$e$.\mathrm{.}123=12\mathrm{.}3\%).)$
