Store Support: Workload Mission Statement
Understand store workload & optimize Develop accurate workload measurementsMeasure store workload & productivity rates for budgeted expense centers
Work Measurement Tools
Palm PilotsTM
M505M515 replaces M505
M100s (qty = 100)Palm ZireTM replaces M100

Advantages of Using Palm PilotsTM (PDAs)
AccuracyTimelinessCapacity Additional DataStudy OpportunitiesEnd User SatisfactionDoable: Because You Can
Study Process
Design StudyWhich technique works best?
Collect DataIs it doable? Enough data in time
Analyze DataLet the data speak
Present FindingsNow that we know this, so what?
Work Measurement Techniques
Work SamplingNon-repetitive tasks : Indirect
Time StudyRepetitive tasks : Direct Observation
Engineered Data CollectionWorkload varies : Direct & Indirect
Work Measurement Projects
Work Sampling:Cash Office (self administered)
Time Study:Price Changes
Engineered Data Collection: Receipts Processing
Work Sampling: Cash Office
Objective: Measure current cash reconciliation processSelf Administered: data anonymousStudy Design: 11 stores, 2 weeksTask list 20 elements maximumResults: Over 10% budget reduction
Work Sampling:
Press green triangle to Start5 Samples/HourPress task buttonPress red button at end of shiftEveryday a study
Work Sampling: Cash Office
Work Sampling:
Time Study: Price Change
Validate current budget methodologyNew process prints price ticketLarge workload variation
Jewelry, ties, dresses, dishes, swimwear, shoes, juniors, infants, men’s, handbagsMerchandise on sales floor/in stockroomsFirst and Further markdowns
Stores vary by density & volumeTicket over 46,000,000 annually
Time Study: Price Change
Time Study:Price Changes
Use start modeEnter qty under # keyEnter notes under paperclipPress hour glass for pausen= sample size
Time Study: Price Changes
Units = 304Hours = 2.174 (elemental time)Export to ExcelTM
Adjust for Performance and PF&D
Time Study: Price Changes
Observation Exclusion
Time Study: Price Changes
Engineered Data Collection:Receipts Processing
Validate budget methodologyConduct studies by store typeEach trailer has unique merchandise mix: hardlines, softlines, cosmeticsObserve entire trailer start to finishAve 10-25 team members/trailerOver 100,000,000 units annually
Engineered Data Collection:Receipts Processing

IE runs Palm PilotTM for each team member
Engineered Data Collection:Receipts Processing
Data summarized in ExcelTM
WinsFocus on observationsReal Time sample sizeEasily to combine studiesStatistically eliminate or analyze
elements or observationsAdditional data
date & time for each observationAlready have a Palm PilotTM
Cool Factor vs. Nerd Factor
Learnings
Must communicate via laptopDo not have software on the networkData not backed up until it’s downloaded
Use Palm PilotsTM with rechargeable batteriesMust be Palm proficient to write notesHard to add elements “on the fly”
ConclusionsUse Work MeasurementNo one knows better than IEKnow the difference
“how long it should take” “how long it actually takes”
Palm PilotsTM are here to stayWork Sampling Results: 3 wks to 3 daysTime Study Results in 2 hrs
