Charitable organizations often have improvement opportunities, but typically don't have the resources of businesses. The BW Food Pantry was fortunate to have Darlene Grandison, who helped them improve their Food Box Process.
Charities often rely heavily on volunteers, and it is crucial to use this help wisely -- not wasting their time. The Food Box Process took 20 minutes to pack a box, limiting the capacity of the organization, and risking the loss of volunteers.
Darlene analyzed the process, and successfully applied many of the principles of Lean that she learned from GoLeanSixSigma. Food storage was reorganized to provide easy access and foster flow. The workspace layout was made more compact, reducing the walking distance and space requirements.
In less than a month she was able to cut cycle time to 9 minutes, reducing the walking time by 45%. While this greatly benefited the BW Food Pantry, the learning from this project can be directly applied to many other food pantries throughout the world!

2. Business Case
Root Cause Analysis
What are the critical findings/root causes that were discovered?
Solutions Implemented
Data showed pack food box time took longer because:
-Food was too far from packing tables.
-Boxers, packers, and stackers crossed paths.
-Food box content changed while packing because items were not count prior
to packing.
-There were no visuals of box content.
-Packing occurred on both sides of tables contributing to the congestion.
Graphical Display of Improvement
Insert a chart, graph or visual demonstrating process improvement
List key solutions that were implemented to address root causes
1. Created designated zones for dry goods, canned goods, and juices/water.
2. Restructured floor layout to allow for continuous flow and to avoid
overcrowding.
3. Sorted and counted food items to determine the quantities of the box
content.
4. Posted visuals of box content.
5. Repositioned volunteers (packers) to work from one side of table.
Executive Summary
Project Results
What is the importance of doing this project? (State in lost dollars,
productivity loss, customer dissatisfaction, cost avoidance, risk, etc.)
What are the measureable process improvements/wins?
Reduced the packed food box cycle time from 20 minutes to 9 minutes.
Reduced the box preparation lead time by 55 minutes.
Volunteers are overworked because it takes too long to prepare food boxes.
Currently, the total cycle time for food box preparation is an average of 20
minutes. If this continues, the food pantry may loose volunteers who are vital
to the operation of the food pantry as well as the other social programs
offered through the developmental center; thus, impacting the chances of
obtaining new clients.

Problem Statement Business Case & Benefits
Volunteers are overworked because it takes too long to
prepare food boxes. Currently, the total cycle time for
food box preparation is an average of 20 minutes. If this
continues, the food pantry may loose volunteers who
are vital to the operation of the food pantry as well as
the other social programs offered through the
developmental center; thus, impacting the chances of
Cycle time improvement for food box preparation will
result in an enhanced volunteer experience. Cycle
Time improvement could translate into monetary
benefits because it will be seen as a well organized
operation which could increase volunteerism in other
areas allowing for addition clients for other service
areas as well as reduce risk of injury.

(What Are They Saying?)
Gathering More Understanding
(Why Are They Saying it?)
Customer Requirement
(What Do They Want?)
Voice of the Customer Translation Matrix
We wait for more instructions, food,
and boxes.
We are wasting their time.
Reduce cycle time from 20 minutes to
14 minutes.
A lot of walking is required. We need better layout of prep area
Improved floor layout to minimize the
number of steps.
Why do food items in the box change? We need to plan ahead.
Count food donations in order to know
the quantity to pack and avoid running
out of food.
If we step away and come back, we
ask how many of food item goes into
box.
We need to know what goes into the
box and inform them.
See sample box, picture, or a list of
food box content.
Key Take Away: The project needs to address the overall Lead Time of food box preparation which impact customer
wait time and motion.
There is too much food, boxes, and
tables in this small area at one time.
We need to improve the traffic flow.
Clear pathways free of equipment and
overcrowding.
We go back through the boxes to
recount or repackage.
We need make better use of their time.
