The document discusses improving warehouse productivity without expensive "Tier 1" technology. It outlines common warehouse challenges such as reducing labor costs and improving accuracy and space utilization. The document then presents a process-centric approach focusing on tactics like cluster picking and put-away by movable unit that can address these challenges with mid-tier WMS and sometimes enabling technologies. Vendors were surveyed about the capabilities of mid-tier WMS, and many tactics were found to be standard or configurable functionality, showing that major improvements can be achieved without large capital investments.
2. What is “Tier 1” Technology?
The term “Tier 1” is frequently used, but is a
gross over-simplification
Conjures up images of “expensive”
technology
“Overkill”
“The Cadillac”
Often used in context of WMS vendors

3. Tier 1 Technology Isn’t Bad
For many large, complex
operations, the only path to
supply chain improvement
involves making a large capital
investment
Many of the technologies which
we consider “Tier 1” have been
the pioneers – developing cutting
edge technology that improves
efficiency
This technology then get adapted
and trickles down to mid-tier
providers over time

4. An Alternate Title for our Presentation…
"How can I improve my
warehousing problems
without a major capital
investment?“
|4
5. But how?
Isn’t this asking to get
something for nothing?
No.
There are two basic ideas
which are under-exploited by
many enterprises today:
1. Leveraging new advances in
technology which they may not
be aware of
2. Sharpening the saw – stepping
back and making fundamental
process changes to improve
the operation
|5
6. Common Challenges
Whether their capital budget
is 5 figures or 8
figures, companies face the
same basic set of challenges:
– Reduce labor costs
– Improve accuracy
– Improve space utilization
Secondary challenges:
– Meet regulatory compliance
mandates
– Meet retail compliance
mandates

7. No Shortage of Solutions…
There are countless solutions available to address these
challenges…

8. Process-Centric Approach
Rather than jumping immediately to
technology, let’s look at several strategies to
address these challenges…
A. Pick more efficiently
B. Put-away more efficiently
C. Pack and ship more efficiently
D. Reduce walking
E. Improve labor productivity
F. Improve accuracy
G. Improve space utilization

9. Process-Centric Approach
Each strategy has a set of execution tactics…
1. Cluster picking 16. Pick restriction
2. "Tandem" picking 17. Large quantity override
3. Receiving staging by zone 18. Min/max replenishment
4. Clustered put-away 19. Demand-based replenishment
5. Put-away by movable unit 20. Slot the warehouse more

11. Focus on Mid-Tier WMS
Mid-Tier WMS has been
in use for at least 15
years
Generally, mid-tier
means a more limited
set of functionality for a
lower price
Often, mid-tier WMS
systems had some key
gaps which made them
not practical for many
users with special
requirements
| 11
12. The SaaS Model
In the last 5 years, the Software-as-
a-Service (SaaS) model has become
a popular means of deploying WMS
With the SaaS model, the software
vendor hosts the WMS application
on their own server and deploys it
via a web connection
True SaaS is multi-tenant: multiple
users are on the same instance of
the software
Customers do not pay an up-front
license fee – just a monthly usage
fee
Upgrading and remaining on the
current version of the software is
much easier
| 12
13. What are the TRUE Capabilities?
Commonwealth Supply Chain
Advisors conducted a survey
of three of the top mid-Tier
WMs providers to assess the
extent to which functionality
gaps have been plugged in
recent years
Two providers offer only SaaS-
based WMS
The third offers both
traditional, licensed WMS and
a SaaS WMS

19. Deep Dive: Pick Methodologies
Which style of picking is best?
Discrete Order Picking Cluster Picking Batch Picking
Zone Pick: Pick & Pass Zone Pick: Pick & Consolidate
| 19
20. Deep Dive: Pick Methodologies
• Pro’s:
– Simple for operators
– Less error prone
Discrete Order – Little/no technology required
– May be the only practical method to
Picking pick very high-cube items
• Con’s
– Very high levels of walking
– Operators return to home-base after
each order is picked
– Each order requires a trip through
the entire warehouse
21. Deep Dive: Pick Methodologies
• Pro’s:
– Dramatically reduces walking
– Possible to do on a limited scale
without a high degree of technology
Cluster – Each order is only touched once
– Orders are ready-to-ship as soon as
picking is done
Picking • Con’s
– Hard to pick a large group of orders
without real-time instructions
– Orders may travel significant distances
without any picks being performed
– Travel distances are excessive in large
warehouses with many SKUs
– Increased likelihood of errors
22. Deep Dive: Pick Methodologies
• Pro’s:
– Reduces walking in larger distribution
centers
– Each order can only be routed to zones
where there are picks
Zone Pick: Pick – Orders are ready-to-ship as soon as
picking is done
& Pass • Con’s
– Almost impossible to manage without
real-time warehousing
– Zone routing can only be done with
complex conveyor systems
– All of the SKU’s in the order travel
through the entire DC
23. Deep Dive: Pick Methodologies
• Pro’s:
– Reduces overall travel distances for the
SKU’s in the order
– Well-suited for orders with diverse sizes
Zone Pick: Pick and shapes of SKU’s
& Consolidate – Well-suited for mixing case and piece
picking on the same order
• Con’s
– Very complex for software to manage
consolidation process
– Requires labor downstream to
consolidate orders
– Requires space to buffer product
24. Deep Dive: Pick Methodologies
• Pro’s:
– Well suited for instances where the
same SKU appears on a large number of
orders
– Well suited for single line, single piece
Batch Picking orders
• Con’s
– Only suits a limited order profile
– Requires additional downstream
handling
– Can be complex to execute

Cost estimates…
– Vendor #1
• Ongoing monthly cost: Averages $3,000-$4,500 per month, but could be as
much as $6,000.
• Implementation cost estimate: $20,000 - $40,000
– Vendor #2
• Ongoing monthly cost: Averages $1,700 – 2,500per month
• Implementation cost estimate: $4,000 (editorial note: Commonwealth feels
this is a significant under-estimate)
– Vendor #3
• Ongoing monthly cost: $0
• Implementation cost estimate: Under $100,000 for license and
implementation for a moderate-complexity project
Hardware: The above prices do not include:
• Installation of wireless network in the DC
• Handheld computers
• Bar-code printers

60. WMS: Keys to success
Don’t rush it!
– Allow 12 – 18 months for selection and implementation
Evaluate all the options (even Tier 1!)
Document EVERYTHING about the current state
– Al normal processes
– All exceptions
Test thoroughly

62. In Summary…
Improved distribution efficiency IS within reach, providing a
company is willing to make at least SOME investment in
processes or technology
Savvy companies who conduct a thorough evaluation of
technology can often find that improvement is not as
expensive as they thought
Don’t rush the process – take the time required to design the
solution correctly the first time.
