Q & A

What is capacity planning in the context of the script?

Capacity planning is the process of optimizing space and resources to meet customer demand for products or services sustainably, similar to how one would plan the space in a new apartment or house.

What is the relationship between capacity planning and manufacturing?

In manufacturing, capacity planning involves optimizing the production process to ensure that the organization can produce goods at its maximum throughput or output rate, considering factors like space and resource availability.

What does it mean to operate at 'full capacity'?

Operating at full capacity means that an organization is producing at its maximum rate of throughput, which is the highest number of units it can produce in a given time period.

What is a 'bottleneck' in the context of capacity planning?

A bottleneck is a point in the production process that slows down the overall production, often due to inefficiencies or limitations in a specific department or process, thus affecting the overall capacity of the organization.

How does system capacity relate to bottlenecks?

System capacity is influenced by the weakest points or bottlenecks within the system. The department with the slowest output or the least efficient process will determine the maximum output rate of the entire system.

What is the significance of 'throughput' in capacity planning?

Throughput refers to the maximum rate of output or production that an organization can achieve. It is a key measure in capacity planning as it indicates the organization's ability to meet customer demand.

Can you provide an example of how capacity planning works in a sandwich shop?

In a sandwich shop, the number of sandwiches that can be made is determined by the inventory levels of bread, cheese, and turkey. If bread is the limiting factor with only enough for ten sandwiches, then the shop's throughput is ten sandwiches, regardless of the availability of more cheese or turkey.

How does the concept of 'capacity utilization' relate to throughput?

Capacity utilization is the percentage of an organization's capacity that is being used. If an organization is producing at its maximum throughput, it is operating at 100% capacity utilization.

What factors might cause a department to become a bottleneck?

A department might become a bottleneck due to various reasons such as having less efficient systems, a shortage of resources, or employees being on vacation, which can slow down the overall production process.

Why is it important for an organization to understand its capacity and throughput?

Understanding capacity and throughput is crucial for an organization to plan and manage its resources effectively, meet customer demand, and identify areas for improvement to increase efficiency and production.

How can an organization improve its capacity and throughput?

An organization can improve its capacity and throughput by identifying and addressing bottlenecks, optimizing resource allocation, investing in more efficient systems, and ensuring that all departments are working at their maximum potential.

Transcripts

So have you

ever went shopping, let's say, for a new apartment or a new house

and you actually purchased or decided to rent a new apartment house?

You probably start at capacity planning at some aspect.

And in this sense, capacity planning is really just

how you optimize space is very similar.

When we talk about manufacturing and capacity planning in that sense.

Right.

You can't put a king size bed

in a very small room.

Right.

Take a look at this floor plan, this floor model.

If this is enough space for you. Great.

But if you put the wrong size furniture in this space,

you're not utilized in your capacity.

Well, it's just like the technologies that we have.

Computers and cell phones, they have limited bandwidth.

And so does the organized nations that produce products.

So in this sense, capacity

is simply the measure of an organization's

ability to sustainably produce

products based on customer demand

or goods and services based on customers demand.

How well can we produce?

And this is going to be based on what we call our maximum

throughput or our maximum rate of output, which is called our throughput.

Right.

So if we can only produce 100 units a day

and we're producing 100 units a day, we're operating at full capacity

and at 100% capacity utilization,

because that's our maximum rate of throughput.

Now what's driving that?

It could be a number of things.

However, we could have a bottleneck, right?

And that bottleneck could be slowing down production in some aspect.

Therefore, we have to improve that bottleneck in order to increase capacity.

Now there's another aspect we can look at, and that's called system capacity.

So system capacity is driven

by the number of goods or services that we can produce based on demand.

But we also consider the strongest and the weakest points within that system.

This is where we begin to get into bottlenecks in specific departments.

That could be the reason that we have such low throughput

or where our maximum output is at a specific rate.

So in this case, your maximum output is going to be driven

by the department with the slowest amount of time

or the department with the least amount of output.

Here's an example.

Let's say you ran a sandwich shop.

Right.

And right now in your three departments, you have 20 slices of bread,

15 slices of cheese, 12 slices of turkey.

Every sandwich that you make requires two slices of bread,

one slice of cheese and one slice of turkey.

How many total sandwiches can

you make based on your inventory levels?

You can only make ten, right,

Because you have 20 slices of bread.

You have 15 slices of cheese.

And then you have 12 slices of turkey.

So your bread department

is the slowest or have the least amount of output.

Therefore, they determine your throughput, which is your maximum output rate.

You can only make ten sandwiches because you only have enough

bread to make ten sandwiches.

You could make at least two more

because turkey would be next in line with 12 slices.

So you could do two more if you had four more slices of bread.

And that's how throughput works in relation to capacity planning.

And this is when other departments get involved in organizations,

when it comes to producing products and how they can particularly

slow the company down or become the bottleneck.

And that can be for a number of reasons, right?

Maybe the bread department has some employees that are on vacation

or their systems are not as efficient in that department

as they are in other departments.

But that's the general sense of what capacity is.

So key takeaways.

Capacity planning and capacity is really just about the measure of

how can a company produce

to meet demand sustainably, produce

to meet demand of customer demand for products and or services.

And in doing that, they have to consider what their throughput is

or their maximum rate of output.

And also considering their system capacity

and what departments may be the reason that their output is so

low or their production time is so slow

because that department is going to drive their throughput

because the lowest throughput or the slowest time

is the one that drives the throughput for the entire system.
