Introduction

Presentation Agenda
Problem Statement
Current State
Variable process times for sanitation at different stations on the ParBake line due to a wide variety of
products, environmental factors, and different operators
Current documentation allows processes to be repeatable between workers, but could still be
improved
Goal: Clean effectively (food safety) but efficiently (production time)
Desired State
Gain productivity hours on the ParBake line
Document of standard work and characterization of sanitation processes
Design a future state of ParBake line regarding process times, improvement opportunities, and a plan
for ensuring how standard work will be followed
Quantify the cost and time savings of proposed improvements
Test improvements through small kaizen projects
Constraints
Meet food safety requirements (post/pre operational checklists)
No improvements can result in a negative ergonomic impact on workers
Any tools used for improvement and sustainment of proposed changes must be easily accessible to
Wegmans
Observations
Mixer Rheon Head Rheon Conveyor Oven Load
Total Observations 8 4 3 3
Time Observations 6 3 3 2
Mixer
Total Time Range:
155 - 284 minutes
Rheon Head
Total Time Range:
67 - 121 minutes
Rheon Conveyor
Total Time Range:
70 - 105 minutes
Oven Load
Oven Load
Fairly simple process but due to equipment
constraints it is very ergonomically demanding
Process: Clean under oven load area
Range:
5 mins to 25 mins
SSD Summary
Requirements “flow down” to subsystems & are all
requirements addressed?
We are currently addressing all process time and
quality requirements, as well identifying sources of
variability
SSD Summary Cont.
Proof of concept and identify sources of variability
Most of the Variability is caused by:
• Product being run
• Technique used by worker
• Tools available to worker
• Operator performing task
• Number of workers performing
task
SSD Summary Cont.
How are you going to test that requirements are met?
Kaizens- small changes to the process to evaluate improvement
Worker/customer feedback- used to evaluate proposed improvements and documentation
Time study data analysis- used to quantify time and cost savings of improvements
Has your design been adequately reviewed?
Gone through problem definition and systems design review with peers, guide, and customers
Met with sanitation employees to discuss project and get buy in
Weekly meetings with guide to discuss progress and analytical methods used to evaluate the process
Three Week Project Plan
Week 10 – Continue to collect time study data,
and begin to develop visual tools for comparison of
actual practices to theoretical practices
Week 11 – Continue to collect time study, and
begin to shift focus to analysis of data
Week 12 – Continue to collect time study, and
continue to analyze the data
