Product Family Matrix

aka Product Quantity Product Rounding PQPR Matrix

Why use a Product Family Matrix?

If your organization offers any products or services that have low volume and high variety...

then the single most important lean technique for dealing with high variability

is to segment your products into the right product families to maximize lean flow,
and then to manage the total demand for the entire product family.

That's what your Product Family Matrix template does for you.

When to use your

Product Family Matrix

You define your product families as one of the first steps

in the Value Stream Mapping phase of a Typical Lean Journey.


How to use your Product Family Matrix

to segment your offerings into rough product families

Find and open your template

Excel Ribbon bar > Systems2win menu

Find and open your Value Stream Mapping Product Family Matrix template

(vsmProductFamily.xlsx)

in the same way that you find and open
your other 150+ Systems2win templates.

Save your working document

following the usual document storage and naming conventions established by your leaders

Open a Blank Sheet

Systems2win menu > Open a Blank Sheet

When you're ready to start doing your own real work...

click the button to 'Open a Blank Sheet'

Excel Ribbon bar > Systems2win tab > Open a Blank Sheet

This blank sheet is where you will do your real work

(not on the Sample sheet)

Rename your new sheet.

If English is not your preferred language

Switch to your language, just like every Systems2win Excel template.

Now your team is ready to get started...

Start with all products and services on one sheet

Tip: You might use two separate worksheets
to define your product families from a Marketing perspective
and an Operations perspective (which can be very different).

Value Stream Mapping is concerned only with the Operations perspective.

List all of your products and/or services in the rows

Be sure to include less obvious "products,"
like prototypes, production of molds or tools, samples, etc.

Be sure to include the services that you deliver — not just products.

List your processes in the columns

In addition to processes and machines, you can also use additional columns
for any other factors that differentiate your product lines (from an Operations perspective).

For example, perhaps some products have similar seasonal demand, or similar shelf life,
or use the same hazardous materials, requirement for a sterile environment, etc.

Perhaps use a code or cell format to identify processes that go through a shared work center,

because when grouping similar products together,
you are often looking for opportunities to group together processes
that might soon be routed through equipment dedicated only to that product family.

For each process used to deliver a product or service, mark the cell with an X

You can also identify possible Alternate processes with an A.

(Or A1, A2 if there are multiple alternate possibilities)

Move rows to group similar products together

Move entire rows or columns

Right-click & drag entire row or column > Shift Down & Move

Get consensus about what a product family means in your company

Usually, a product family consists of only products and services that are similar enough to be treated as a single product for scheduling purposes.

Define your Product Families

Only AFTER you have done all of the above…

Define the Legend for your Product Families

giving each a Description, a short Code, and a Color.

 

Usually... that's it... you're done

Your Product Families are now very obviously and visually defined


Optional: Refine Each Product Family

If (and only if)...

there is any product that might take 30% longer than the Product Family average…

then...

Create a separate worksheet for just that one Product Family

Systems2win menu > Copy Sheet

If you copy the existing worksheet as a starting point for the new one...

use the special utility: Systems2win menu > Copy Sheet

Enter Process Times

Unhide the column for 'Total Process Time'

Assign and train team members to gather time observation data.

Deal with lengthy processes

Any process that takes longer than 30% of average might require special attention

to identify any offerings that take so much more time to produce
that they might need to be either moved to another product family
or be scheduled using special techniques

See online training for High Mix Value Streams

Optionally analyze any potentially-constrained resources

Unhide the columns for 'Constrained Resource Analysis'

to determine resource requirements

(for equipment or any other potentially-constrained resource)

Tip: You can copy these columns for as many resources as you need to analyze.
