8. Field Service Kiosk

9. Field Service Kiosk: Situation
Field service industrial company
Spare parts Administration
Parts are „on-hand“
Parts are ordered from shelf
Parts are ordered from factory
Direct vendor ordering
CAD/document Direct update
Challenge: big docs/slow lines
Tools administration
Tools „on hand“
Tools „just-in-time“
Staff & Time Management
Example Challenge:
100 field service spots
30 employed master engineers
50 external service companies
20 industrial firms with self-maintenance

11. Field Service Kiosk: Situation
Requirements
Time Recording
Direct Entry
Via Web Forms
Via
Via PDA
Tool & spare part ordering External catalog ordering Tool return tracking CAD direct update *

12. Field Service Kiosk: Requirements
Time Recording
Direct Entry
Via Web Forms
Via
Via PDA
Tool & spare part ordering
External catalog ordering
Tool return tracking

15. Example: MoBlogging Simple Requirement Classic Solution
A travelling salesman enters service data into a local database
The data needs to be synchronized with the central CRM database
Classic Solution
Copy data to a workstation
Upload data
A better solution
data to a service that will post the data
This is known as “blog by ” or “MoBlogging” for mobile blogging

16. SOA Solution Path Multiple Input Formats
HTML, , Office, PDA, WikiText etc.
Data Conversion to Harmonized Format
E.g. HTML with Wiki Tags

17. Example: Document distribution
Select sales orders and drawings from a database
Display data as web page
Select results from Web page
them as ZIPped PDF and/or XML, Word
Archive the produced result as attachment to CRM
PHP, Ruby can do
Built-in
Built-in PDF, ZIP etc.
Word conversion by .NET
SAP, Oracle ???
Solution:
Let ZIP do the ZIP
Let Acrobat do the PDF
Let .NET build the Word document
Endlessly complicated!

18. Example: Document Management
Classical client server case
Classical Printing
Server extracts data to print
Data is sent to print server
Print server creates pixeled output
Disadvantage
Multiple redundant layouts
Redundant technology skills
Printer coordination needed
Explicit Printing via Service
Extract data to unified XML format
Send data to XML formatter
Formatter creates pixels
Advantage
Clients share same resources
One form design
One central print control
