In chapter twelve,
we're looking at a product structure tree.
A product structure tree
is literally just dissecting a product,
and here we're going to take a look at the tongue twister lollipop which is
shown in the pictures below.
And we're going to construct
a structure tree for a bag of twenty
fruit
flavored lollipops.
In order to do this,
we need to figure out what's in there. Let's start
with, we want
a bag
of twenty
lollipops,
and they're the tongue twisters.
In this
this is
our level zero.
Level zero says that it's an end product.
Looking at this,
we have to explode this out, and figure out what exactly makes up the lollipops?
What do we get in as what's called a parent item?
Somebody else makes it and we just use it,
and what do we actually produce here
that we have to blowout
and say this is what it is. So on our bag of lollies,
it's actually made up
of a bag and
the twenty lollipops.
This is
considered level one.
Now, I'm going to say that we buy the bags. All we have to do is seal them up
after we put the lollipops in.
It's a parent item.
The lollies though, we make,
and each one of those twenty lollipops
has a stick,
the candy,
and the wrapper.
Now, we're separating this out to one lollipop.
What goes into one lollipop, 'cause here we had, up above,
twenty lollies in the bag.
What is one lollipop made up of?
The stick, we're gonna buy the sticks, we get them premade, we're just sticking them into
the candy.
The candy though,
we actually make.
The wrapper, we buy.
So all we have to do is wrap each one individually, they're pre-cut and everything
for us.
The candy though, this right here by the way
is level two.
The candy
we make
and it's made out uh...
sugar
there is corn syrup in it,
there is flavoring,
and there is coloring in it.
Now,
personally,
it doesn't give us the exact amounts that are in there so we're going to guess
and this right here is
level three,
but I'm going to say that there is one ounce of sugar
and a half an ounce of corn syrop
in each lollipop.
Rhere are six drops
of flavoring,
and eleven
drops of color.
I'm just guessing,
but that's what I'm saying we're using
to produce these lollipops.
Level zero, one, two, and three,
this makes up
our product structure tree.
So, we start with the end item,
the product that we are producing,
and we go on
to explod it out,
so that we can look at this and actually take a look at what we
order, how many do we need,
because if we take a look at at the sticks here for every single bag, we know
we need twenty sticks.
If I'm making five thousand bags of these lollipops, the tongue twister
lollipops,
and there's twenty sticks per bag, I need to multiply that out, so when I go to order,
I'll know.
That's the purpose behind this, and or nowadays it's done on the computer and
we're going to
match things up uh... because this might be... this might not be the only item we
produce that uses sugar,
so that we can order sugar for everything,
when we're producing, getting our supplies in,
or it might be the only thing, the only lollipop we make, we just make hard candy,
so,
we only need the sticks for this so that we understand how much we need when we
need it, etc.
This becomes very important
when we go on to
ordering items. So, this is the end of the product structure tree and how you
create a product structure tree and you do need to put your levels in there.
Level zero will always be your end item.
