Several years ago, Rob built a table for his son to use in building LEGO creations. The table allowed his son to stand while building, provided a frame to hold LEGO base plates, and got the LEGOs off the floor. Several of Rob$$s neighbors saw the table and asked him to build tables for their children. The tables grew in popularity and Rob eventually quit his job in $2018$ and founded LeTable Incorporated. He now works full$-$time building custom LEGO tables.

Customers select from four different sizes of tables:

$1.$ Small, which holds $4$ base plates

$2.$ Medium, which holds $8$ base plates

$3.$ Large, which holds $16$ base plates

$4.$ Deluxe, which has multiple levels as well as conduits for electric lights

Customers can also select from five different colors:

$1.$ Blue

$2.$ Red

$3.$ Yellow

$4.$ Natural $($polyurethane only$)$

$5.$ Stained

Rob would like to see an analysis of the time to make and ship different table sizes $(20182022).$

$1.$ Analyze the results.

$2.$ What additional analysis of process time would you suggest that Rob analyze?
