San Diego Distribution Center $($DC$)$ Process $-$ Draw a process map of the following scenario:

Dealer emails an order to the DC which is automatically printed on the copier. One out of $25$ orders are lost because the copier jams or an employee accidentally throws it away.

Printed order sits in an inbox around $2$ hours $(0$ to $4)$ until internal mail picks it up$.$

Internal mail takes about one hour on average to deliver the order to the picking area. One out of $100$ orders are delivered to the wrong place.

Order sits in clerk$$s inbox until it is processed for $0$ to $2$ hours $($average $1$ hour$).$ Processing time takes $5$ minutes.

If item is in stock, worker picks and packs order $($Average $=20$ minutes, with range from $10$ to $45$ minutes$).$

Inspector takes $2$ minutes to check order.$$ Still, one out of $200$ orders are completed incorrectly.

Transport firm delivers order with average delivery time of $1$ to $3$ hours $($average $2$ hours$).$

If the item is out of stock, the clerk notifies the dealer and passes the order along to the plant while arranging a special shipment directly to the dealer, usually within a week.

Average Time between Ordering and Delivery for an in$-$stock item is $6\mathrm{.}4$ hours $(387$ minutes$).$ Can be as long as $11\mathrm{.}3$ hours $(682$ minutes$).$ If an item is not in stock, it will take even longer.

Of the $6\mathrm{.}4$ hours an order spends on average in the process, a full $3$ hours is waiting time.

$5$ percent of the orders are $$lost$$ before they even get to the picking area. For the orders that do survive to this point, $1$ out of $200$ will be shipped with the incorrect items or quantities.
