CHALLENGE OF NEW W/H LAYOUT

Crescent Parts is a distributor of HVAC equipment and parts. They were growing and needed to expand warehouse space. They found an existing building that allowed them to combine 2 warehouses into one new larger warehouse. Many Lean Warehouse projects involve transforming an existing warehouse to a Lean layout. This project took the two smaller warehouses and moved them into a new building with a Lean layout.

IMPLEMENTATION DETAILS: Inventory Sizing & Storage

  • Formed 5S Implementation Team to design and lead the 5S implementation
    • Branch manager, Director of branch operations, Buyer
  • Determined what items would be stocked based on combined demand of both branches
  • Calculated maximum inventory of all SKUs
  • Calculated cubic feet and linear feet required to stock maximum inventory
    • Validated calculations by back-calculating existing space requirements

IMPLEMENTATION DETAILS: LEAN WAREHOUSE LAYOUT

  • CENTER OF GRAVITY: The first step of the layout is to determine where most of the material movement will happen. On the right size of the drawing is the branch ‘store’ where HVAC repair technicians pick up small parts. The dock doors are on the bottom right side of the building.
  • STAGING AREA: It is a best practice to leave a lot of space for staging. This prevents stashing of inbound or outbound pallets wherever room can be found. Staging areas are shown in a light pink color. Note the inbound and outbound areas in addition to a customer loading area

IMPLEMENTATION DETAILS: LEAN WAREHOUSE LAYOUT

  • MAIN AISLE (the highway of the warehouse): We placed an aisle from right to left that would allow two forktrucks to pass each other without stopping.
  • SKU LOCATION BY VELOCITY: The fastest moving items, and those used most often by customers picking up from the branch ‘store’ are located in the V1 zone. Larger and hard-to-move items with medium velocity were located in V2. V3 items are to the left and back of the warehouse.
  • AISLE WIDTH: Aisles are 6 feet wide for shelving and 12 feet wide for racking and floor stock.
  • PRODUCT FAMILY: While we usually locate items by purely velocity the team decided to keep product families together. However, the faster moving items in a product family are located close to the main aisle.

AISLE SIGNAGE

  • We benchmarked grocery stores as example for aisle signage, making it easy for new employees to find locations
  • Only even numbers are used so aisles can be added, if needed, in the future.
  • Aisle-bin-level coding supports snaking through the aisles to minimize the pick patch

RESULTS

  • The move from the two branches to the new warehouse happened in 4 days
  • 100%+ labor productivity improvement
  • Needed to staff with the employees from just one branch, even though this project combined two branches into the new warehouse
  • Center of Gravity concept streamlined picking and receiving-putaway

“We used Supply Velocity to rethink our sales process. By analyzing the entire process we found wasted time in our Sales, Admin and Operations departments. Streamlining this process created extra time for each Sales Rep, allowing them to spend more time with Customers and increase the value we add. Gross profit margins are up 40%!

We are now using Supply Velocity to help us rethink our entire Strategic Plan.”

Jeff Reitz, Vice President, Central States Bus

“In a time of volatile supply chain disruption, Supply Velocity is helping us develop Demand and Supply Planning processes to proactively tackle these new challenges. They are genuine partners, working with our team, facilitating and teaching.”

Jane Thrasher, Vice President of Supply Chain, Horizon Hobby
“Myerson engaged Supply Velocity, specifically Ray Davis to visit our plant in Trinidad to conduct a two day assessment of our production procedures and provide us feedback on areas for improvement and where applicable, areas for future analysis.

Put simply, we got everything we paid for and in addition to more in depth analysis, we got specific tasks that were immediately actionable. Our local management team found Ray to be engaging, highly credible and insightful based on his wide experience. In other words the cultural differences and lack of specific industry knowledge weren’t impediments to things we could implement immediately and on our own. In a nutshell it was money well spent and will pay itself back many times over.”

Lee Hartwell CPA, Plant Manager, Myerson Tooth
“Supply Velocity has helped Clean succeed in a number of ways. First, they provided the education that kicked off our Lean Process Improvement journey. They also facilitated a number of large supply chain and process improvement projects including: 1) building quality into our direct-labor productivity incentive program, 2) designing the layout of our garment warehouse, and 3) streamlining our route service process.

We have integrated the methods that Supply Velocity taught us into our management and strategic planning. In the process our quality measurement has improved 22% from 2013 to 2015, we have reduced required annual labor by 2200 hours from the garment facility layout project and we’ve seen 50% decrease in error rate. Obviously the numbers speak for themselves, but just as important, Supply Velocity has been fun to work and have become true partners. They have “taught us how to fish” so our internal teams are able to implement change on their own, with the skills we learned from Supply Velocity. This relationship has been invaluable.”

Jeff Lazaroff, Senior Vice President, Clean Uniform
“Supply Velocity is driving instrumental change in our inventory management processes. This is critical for us to be competitive in a supply chain environment with numerous disruptions. They are making change happen, which can be challenging in a 182 year old organization.”
Jim Carroll, Executive Vice President Operations, Schaeffer Manufacturing
“We engaged with Supply Velocity to help us embed process improvement at all levels of the business. Our team learned from Mitch to let the data drive decisions, to use Lean tools to help us see our processes critically and objectively, and to create a control plan to manage all of the tasks that were the outcome of the data study.

The project turned out to be very significant to the company and most importantly, our customers. We reduced our customer wait times by 40%, and cut in half the labor cost to fulfill customer orders.

Some results are not able to be measured. However, as a result of this project, we have started to build a Lean mindset and culture, which is part of our strategic mission to save our customers money. Supply Velocity has been a valued partner in this mission.”

Dionne Dumitru, COO, Weekends Only

“Supply Velocity gave us the tools to analyze our business and processes based on the facts and numbers versus our perceptions. Our common quote was “Let the numbers lead us”. The key for our organization was how quickly we moved from classroom to actual project initiation. We were able to jump in, start using the tools and see a difference right away.

The get-into-action approach was good for our culture.”

Ned Lane, President, CeeKay Supply

“Our experience with Supply Velocity was one of the best values we have ever had from a consulting project. Cyril Narishkin brought a structured lean methodology, invaluable experience and engaging facilitation skills to help us streamline a very complex and disjointed sales order process. Just as importantly, our team now has the knowledge and process competencies to address other business improvement opportunities going forward.”
Mike Howard, CEO, Aspeq
“In thirty years of hiring consultants, Supply Velocity, Inc. was the first to tell me what they were going to do, set a price they stuck to and substantially exceed my expectations. I have recommended them to friends and acquaintances. They were true partners in assisting with the turnaround of an acquisition we had been struggling with for two years.

Their math-based technology, solid down-to-earth facilitation skills, and positive, patient and enthusiastic attitude combined to make our implementation of Lean a very rewarding experience.

We increased our production by 50% in the first month of implementation and continue to see improvements. Improvements have not only been realized in productivity, but also in quality and morale. We have increased profitability by $2M on flat sales of $10M.

Based on Supply Velocity, Inc.’s integrity and our results, I will continue to refer them to others and utilize them in the future as we expand our company through acquisitions.”

Bill Gilbert, President, Fusion Coatings
“Isolating a problem, finding short, and long term solutions with measurable results is what was promised and results is what was delivered by Supply Velocity. Upon launch of the Lean Six Sigma Selling System, we knew more about our customers, our products, and were able to create a solid plan to increase sales of our most profitable products. Within months of implementation, our booked sales jumped 60% and our most valued customers were getting direct, active, and calculable attention.”
Mark A. Presker, General Manager, Architectural Millwork of St. Louis
“The role of the Erie Insurance Marketing Department has been evolving over the past several years – from a support role to a more critical role of driving growth in our organization. Because of our increased workload and desire to prioritize the most critical projects, we hired Supply Velocity to teach us the skills of Lean Six Sigma.

Participants included the Promotions, Market Research and Agency Licensing sections of the Marketing Department.

We learned valuable tools to help us to prioritize based on the voice of the customer.

I firmly believe these skills made a difference in how we work every day. We are moving new projects forward, eliminating or changing ineffective processes, and we are a much stronger department. We continue to use the tools to help us with our highly-complex and time-consuming projects. Supply Velocity helped us to accomplish our goals.”

Karen Rugare, Director of Marketing, Erie Insurance
“In 2015 we began working with Dr. Mitch Millstein to optimize our inventory locations supporting e-commerce and in-store inventory needs. From this work we developed a new omni-channel warehousing and inventory plan that entirely redefined our approach to warehousing, inventory management, store distribution and fulfillment. As a result of the analyses by Dr. Millstein we have begun the move to an improved omni-channel design by reassigning MSAs to new warehouses, greater leveraging of in-store inventories to satisfy e-commerce demands, and exploring acquisitions of new warehousing space in strategic locations. We have already seen an improvement of $300,000 from both more efficient shipping strategies due to better inventory management.”
Rob Bowers, Vice President of Strategy, Total Hockey
“Supply Velocity has provided the technical expertise and political capital to move our project forward. They have just the right amount of push and the right amount of support.

“Mitch Millstein and his team helped guide our shop fabrication division in the re-layout of our custom pipe and steel fabrication facility when we moved into a new building. It is not only the results but how he helped. We were involved in every step. I personally did time studies and was able to see the non-value added steps required to manufacture in our old layout. When we created our new layout, everyone was involved, from the executive team to our direct labor force. With Mitch’s help we increased our throughput by a 3x multiple, while providing more competitive prices to our clients as a result of the efficiency improvements.

This has enabled us to not only make more money but also to expand our commercial reach and serve more, and larger customers. I would recommend Supply Velocity to any company that wants to make improvement in supply chain and operations.”

Geoff Gross, President, Gross Mechanical

“C&R was struggling with labor productivity. The construction crews were often missing materials that they needed to do their work. This caused significant idle time. Supply Velocity, Inc. and C&R used value stream mapping and visual management tools to make dramatic improvements in operations. Most importantly, two years later C&R is sustaining and improving on the implementation. C&R’s return on investment was 11:1. C&R had a record year last year in both sales and profits and would not have been able to pull it off without the changes Supply Velocity, Inc. helped us make.”
