Select all the statements that are true.

Product$-$oriented layouts tend to have high levels of work$-$in$-$process inventories.

One drawback of a product$-$oriented layout is that work stoppage at any one point ties up the whole operation.

A product requires $24$ separate tasks, and the sum of those task times is $14$ minutes; if the cycle time is $2$ minutes, then at least $12$ workstations will be needed.

Cycle time is the maximum time that the product is allowed at each workstation. If the schedule calls for the production of $120$ units per day and $480$ minutes of production time are available per day, the maximum cycle time would be $4$ minutes.
