In This Session You will get to know the basics of Pick by Voice (PbV) functionality as well as the benefits and advantages of pick by voice functionality compared to mobile with screen-based devices We will also introduce some of the unique features of SAP EWM and process control options to run process You will learn how PbV systems are integrated into SAP Management We will nstrate a voice- process 1

What We ll Cover Basic aspects of voice-controlled 2

What Is Pick by Voice About? Pick by voice primarily is about voice-driven order Pick by voice makes use of speech recognition and speech synthesis to interact with the operator The minimum equipment: A mobile computer connected via WLAN to the warehouse management system Headset with a microphone connected via radio frequency like bluetooth to the computer And you can connect optionally: Scanner devices, e.g., finger scanners keeping hands free Screen devices for multi-mode user experience Mobile printers to print labels during operation 3

What Is Pick by Voice About? Continued Picking tasks are transferred in real time to the mobile computer The task data is read to the operator The operator confirms commands by talking confirmations like okay Notes Real time does not mean that there is a real time connection to the WM system PbV systems sometimes make use of batch processing Batches of work are transferred via IDoc and confirmed via IDoc Of course, SAP EWM can be connected with PbV devices in real time Real time is helps a lot to optimize resources and to manage exceptions 4

A Very Simple Process Flow 1 2 Instruct operator to go to location Ask to pick the planned quantity 3 Instruct operator to go to packing Check Digit of Location Quantity OKAY Check Digit of Location 5

Some Complications for PbV Processes Picking Preparation Information Difference Handling & Physical Inventory Multi Order Picking Other Prepare boxes, cartons, pallets, pick & pack Number of items/open items Update actual quantity Split quantity into different boxes Skip orders Assign boxes to positions on device Weight and Volume Confirm empty bin Multiple picks from source bin Skip items Apply preprinted labels or print labels Confirm quantity after Assign or print item labels Exception execution, e.g., go to clearing 6

Benefits and advantages of Pick PbV Can Improve Picking Performance Significantly 1. PbV can contribute significantly to improve the operational efficiency 2. Cost of PbV hardware is in the same range as for handheld computers (plus 15 to 25%) 3. Performance increase per picker is reported by more than 15%, but some reports are much higher than this Traditional mobile device processing versus PbV Traditional mobile device processing accepted to save cost and to improve quality But many success stories prove that PbV is often faster than mobile device processing How to valuate the performance benefits of PbV: Is it 5% or 50%? Test it Ask for or buy hardware devices and connect them to SAP EWM! Analyse it Makes use of methods for working time analysis like Methods-Time Measurement (MTM) vs. It is about time to question the benefits of traditional mobile device! 7

Benefits and advantages of Pick Where Does the Performance Improvement Come From? 1. Parallelization of communication and processing speeds up the operation 2. Handling tasks for/with mobile devices get obsolete 3. Operators don t loose their focus if they do not need to switch Parallelization of communication is primarily related to walking and Walking distances need to be sufficient to establish the communication A single quantity pick is more advantageous over in several steps from one bin Additional physical moves are not needed anymore Moves to perform scans get obsolete Moves to verify tasks get obsolete Moves to enter data get obsolete vs. 8

Benefits and advantages of Pick PbV Can Increase Process Accuracy Significantly 1. Error rates are quite often reported to go down dramatically with PbV 2. Pickers can focus on the execution without interruption because of cross checking the content of a screen device Savings from better accuracy will already make the ROI 5 times less errors of PbV compared to traditional mobile device Calculate yourself: Number of cases per day multiplied by the error rate and by the error cost: Example 1: Traditional, 10.000 cases per day, 0,5% errors and $10 per error and 250 days per year $125.000 per year Example 2: Voice, 10.000 cases per day, 0,1% errors and $10 per error and 250 days per year $25.000 per year vs. 9

Benefits and advantages of Pick Comparison of Error Rates of Picking Methods 1. All case studies show significant reduction of error rates 2. Comprehensive comparisons are rare, but all come to the same conclusion Error Rates of Picking Methods 1.4 1.2 1 0.8 0.6 0.4 0.2 0 0.35 Paper based 0.5 Pick to Label 0.49 Handheld Terminals 0.4 Pick to Light 1.17 Handheld Terminals with Pick to Label 0.08 Pick by Voice 40 35 30 25 20 15 10 5 0 vs. Average Error Rate (%) Number of Installations Source: Andreas Lolling, Analyse der menschlichen Zuverlässigkeit bei Kommissioniertätigkeiten, Analysis of human reliability of operations, Shaker Verlag, 2003 10

Benefits and advantages of Pick Other Benefits and Advantages of Pick by Voice Eyes and hands-free is a big advantage, e.g.: Better ergonomics for heavy and large items Temperature: Frozen areas and gloves and handling of mobile devices Better overall safety Less user training Operators usually need less training It is easier to move operators to other areas Improvements in speech recognition make voice pattern obsolete Initial speech training effort for devices will become obsolete vs. Multi-modal devices combine lightweight displays with PbV capabilities 11
