Product Mix Segmentation using P-Q-$ Analysis

Background
Although P-Q Analysis (P= Part, or Product, Q= Quantity, or Production Volume) is a simple and effective
method for product mix segmentation, P-Q-$ Analysis ($= Sales, or Profit, or Revenue) simultaneously
considers two criteria to rank order and classify products into different segments. P-Q Analysis identifies
at most three product segments (High, Medium and Low Volume) in the product mix of a jobshop.
Whereas, P-Q-$ Analysis could identify up to four different segments in the same product mix. Ideally,
each business segment ought to be served using a different combination of facility layout, manufacturing
technology, workforce skills, management strategy, etc.!
Justification for this Strategy
When implementing Lean in a high-variety low-volume (HVLV) manufacturing facility, especially in a
jobshop where small batches of high-priced products are often the norm, we could be erring by focusing on
the Value Streams of products that belong in the High-Volume segment that is typically identified by P-Q
Analysis. There are two reasons why P-Q Analysis could often select the wrong products to focus on: (i)
the High-Volume products do not belong in the High-Revenue segment and (ii) the products in the (LowVolume, High-Revenue) segment that are often profitable are ignored by P-Q Analysis! Cash flow in any
business can be improved by (1) completing high-value orders in the shortest period of time and (2)
reducing the Seven Types of Waste that decrease margins for the low-volume but high-margin parts.
From the perspective of Flow, three types of operational costs – Transportation, WIP (work-in-process
inventory) and Queuing – increase manufacturing costs. Two costs – Transportation and Queuing – are
heavily dependent on production volumes and container sizes; but, WIP cost is heavily dependent on
product value, which is usually reflected in the Sales earned by each product. So, instead of focusing on a
sample of products selected using a single criterion – Quantity – the P-Q- Analysis method recommends
focusing on a sample of products that is drawn from several segments of the product mix – (High-Volume,
High-Revenue), (High-Volume, Low-Revenue) and (Low-Volume, High Revenue). As shown in Figure 1,
P-Q-$ Analysis creates a two-dimensional scatterplot for the entire product mix of any jobshop as follows:
 The horizontal axis (X) represents Quantity (or Volume).
 The vertical axis (Y) represents Revenue (or Profit Margin).
 Every point in the scatterplot represents a particular product.
 Q* is the threshold value of Q that separates Low-Volume products from High-Volume products.
Similarly, R* is the threshold value of Sales that separates the Low-Revenue products from the HighRevenue products. There are simple as well as sophisticated methods for choosing the points – Q* and
R* – on the two axes. Those methods are beyond the scope of this introductory article. If we draw a
vertical line on the X axis at Q* and a horizontal line on the Y axis from R*, then the P-Q-$ scatterplot
gets divided into four quadrants. Each product will lie in any one of the four quadrants, depending on
its (Q, $) values. The four quadrants are (High-Quantity, High-Revenue), (Low-Quantity, HighRevenue), (Low-Quantity, Low-Revenue) and (High-Quantity, Low-Revenue). Each quadrant defines
a product mix “segment” that, ideally, ought to be managed as a separate business and be produced in a
separate area of the facility with a suitable layout for that area, manufacturing technology, workforce
skills and management strategy!

Figure 1 P-Q-$ Analysis Scatter Plot of the Product Mix in a Hypothetical Jobshop
Case Study
Table 1 shows the input data from an actual project used for P-Q Analysis (where P= Part or Product and
Q= Quantity or Production Volume). Typically, the “Quantity” (# of pieces shipped) and “Revenue” ($
earned) for each part are for a year, or longer production horizon. The “Routing” is the sequence of
workcenters that a part must visit ex. Part No. 1 (80-A37353) has the routing:
17→6→2→11→10→29→54→55. Figure 1 and Table 2 are the graphical and tabular versions,
respectively, of the P-Q Analysis output that would be used to segment the product mix of any jobshop. In
Figure 1 the Parts are sequenced from left-to-right along the X-axis in order of decreasing value of Quantity
of each (individual) part; whereas, the Y-axis on the left side of the graph shows the Quantity of each
(individual) part and the Y-axis on the right side of the graph shows the Aggregate Quantity for any group
of parts. In this particular example, the curve in Figure 1 is “sharp” and the points where the curve has
sharp bends are potential cut-off points between different segments of the product mix, such as HighVolume (Runners), Medium-Volume (Repeaters) and Low-Volume (Strangers) segments. In Table 2,
where the parts have been sorted in order of decreasing value of Quantity, the Total Aggregate Quantity for
a sample of parts comprised of the first 23 parts in the total list of 79 is 1411592 (see Row # 23 in the table)
accounts for about 80% of the Total Aggregate Quantity for all 79 parts (which is 1766478). So, using
Figure 1 and Table 2, we could segment the product mix into at least two segments, one comprised of the
top 23 parts and the other containing the remaining 56 parts.
Next, instead of using Q, if we used Sales and did a P-$ Analysis, the Pareto sort of the products would
have sequenced them by decreasing value of Sales, as shown in Table 3 and plotted in Figure 2.
Are the two samples of parts chosen using either Q (Volume) or $ (Sales) the same? No! So why not
enhance the Pareto sorting algorithm to simultaneously incorporate both Q and $? Here is how to do it --Using the columns of data “Part”, “Quantity” and “Revenue” in Table 1, first produce the scatterplot that
appears in Figure 3. Even if you did no further analysis and eyeballed Figure 3, you could produce a
segmentation of the product mix as shown in Figure 4. In that figure, the scatter plot suggests that the
product mix of this jobshop could have three segments – (High-Volume Low-Revenue), (Low-Volume
High-Revenue) and (Low-Volume Low-Revenue). So, if we had we relied only on PQ Analysis (Table 2),
we would have ignored the products in the High Revenue Low Volume segment. And, if we had relied
only on P$ Analysis (Table 3), we would have ignored the products in the Low Revenue High Volume
segment.
Now, for the purpose of this article, you could do something better than just eyeballing to create a 4quadrant split of the product mix as follows: Locate the point (R*) on the Revenue axis that corresponds to
the Revenue value for Part #80-4030007296090 (R*) which is the last part to be included in the Pareto sort
to select the P$ Analysis sample. Draw a vertical line through this point. Similarly, on the Quantity axis,
locate the point (Q*) that corresponds to the Quantity Value for Part #80-121009-00 which is the last part
to be included in the Pareto sort to select the PQ Analysis sample. Draw a horizontal line through this
point. Thereby, you will split the PQ$ Analysis scatterplot into four quadrants. If you desire to know the
exact PQ$ Analysis results produced by the proprietary algorithm in the PFAST software that we use to
implement JobshopLean, please send me an email at [email protected] to request that information.
Managing a Jobshop’s Different Product Mix Segments Differently
How does one translate the results obtained using this LAT into improvement projects (or kaizen events),
management policies, strategic plans, etc.? Here are some examples of the follow-on projects that could be
undertaken using the PQ$ Analysis results:
Market Diversification: If you study Figure 3, this particular jobshop does not have a single part # in the
(High Revenue, High Quantity) quadrant. That figures because a jobshop’s niche is not low-mix highvolume manufacturing! However, creative jobshop owners do not pass up on any opportunity to accept a
Long Term Contract from a defense prime or an OEM to supply a single part (or a well-defined part
family) that will be ordered on a consistent basis (think takt time!) all through the year, maybe even for a
few years! For example, one machine shop set up a stand-alone robotic cell for a single part ordered by a
defense prime. Another machine shop installed a dedicated flexible manufacturing cell operated by a
single operator to produce a single part for an automotive OEM in their state.
Facility Layout, Virtual Cells and Workforce Training (and Compensation too!): A manufacturer of
hydraulic pipes and couplings produced 2,000 stock keeping units (SKUs) with 48 hours lead-time
customers. The manufacturer was finding it increasingly costly and difficult to consistently achieve this
lead-time. Analysis showed over 50% of sales came from only 92 products, or less than 5% of the entire
product mix. The other products were ordered infrequently in small quantities, even as single items.
Armed with this information, the company decided it needed two types of factory: a high-volume repetitive
facility and a flexible job shop. However, it was not cost effective to build two factories. Or even to
physically separate the equipment. The company worked out what equipment would be needed for highvolume products in a fixed sequence. This equipment was painted green. Employees for this equipment
were selected based on their preference to work routines. They were given green overalls. The remaining
equipment was painted beige. Employees were selected on their preference to tackle difficult and complex
situations, in their case, lots of setups and unusual machining issues. They were given beige overalls.
Although the equipment and staff were totally intermingled on the shop floor, each business operated
totally differently. The green factory had fixed hours of work, JIT deliveries and improvement activities
focused on achieving faster cycle times and increased productivity. The beige factory had hours of work
that varied according to the level of demand each week. Materials were only purchased when required.
Improvement activities focused on flexibility and responsiveness. This company succeeded in creating and
operating two businesses under the same roof, even each business had different policies, procedures and
appropriate performance metrics. For complete details on this eye-opening case study, please read Page 27
“One Business or Two?’ in this book --- Glenday, I. (2005). Breaking Through to Flow: Banish Fire
Fighting and Increase Customer Service. Ross-on-Wye, United Kingdom: Lean Enterprise Academy.
ISBN 0-9551473-0-1.
Vendor Selection, Purchasing Management and Inventory Control: High-volume products, which
allow production batch sizes to match a Make-To-Stock inventory policy, also influence how far the
suppliers are from the company location, and for FTL (full truck loads) at time of delivery. In contrast,
high-revenue orders made from rare metals like titanium (which is not easily available if shipped from, say,
China) merit keeping a very close watch on onhand inventory levels, supplier lead times, market price, etc.
Priority Scheduling of Orders Loaded on Bottleneck Resources: By knowing which products are of
high-value but to be delivered by certain due dates, as opposed which orders are being run to replenish
kanban-triggered onhand stock, appropriate inventory control systems can be used for products in different
segments. In fact, products in the (High-Volume, Low-Revenue) segment could be outsourced but labeled
at the time of shipment by the company selling them to customers. What about shopfloor scheduling? The
color of the paperwork, containers, etc. associated with a high-revenue order could be different from the
paperwork for the other orders, so everybody on the shop gives a higher priority to minimizing WIP
corresponding to that category of orders.
Equipment Purchases: The value and volume of production of different products easily influences the
flexibility and sophistication of manufacturing equipment. High-volume assembly facilities are
increasingly embracing “right-sized automation” i.e. equipment that is designed for producing a welldefined low mix of products in a well-defined range of volumes. On the other hand, most jobshops that I
know, who struggle to hire and retain multi-skilled equipment operators, are the first to purchase flexible
multi-function single-setup machines, some capable of lights-out operation.
About the Next Column
In the next column, we will conclude this series on the PQR$T Analysis approach to accurate product mix
segmentation as a crucial starting point for jobshops on their Lean journey. In my next column, I will
describe PQT Analysis, a method for Product Mix Segmentation that considers both QUANTITY and
DEMAND REPEATABILITY for any product to segment the entire product mix of a jobshop, especially
when 1000+ routings are involved. PQ Analysis, which is based on the old and obsolete Pareto Law (or
80-20 Rule), fails to consider how many times any product is ordered, the size and variability in order sizes,
and the time interval between consecutive orders. Which is why PQT Analysis, instead of PQ Analysis, is
a preferred method for identifying the Runners, Repeaters and Strangers in a jobshop’s product mix.
