universally acceptability of the Web services
standards are important issues to ensure effective use
of this technology (Kotok, 2004). This has not been
achieved yet for all the layers (reliability, security,
workflow and transactions, etc.) of the Web services
stack except for the foundational core standards for
service exposure, service usage and service message
exchange format – SOAP, WSDL and UDDI
(Mallick et al. 2004). This means it would not be
incorrect to say that Web services standards in their
current maturity may have limited applicability in the
role of a true business process integrator.
However, due to its tremendous potential as an
information exchange mechanism, it can enhance the
potential of other data collection, data processing and
information dissemination mechanisms and
applications. Being available in two modes –
synchronous (based on the RPC model) (Adams,
2002) and asynchronous it can be utilized in either
real-time mode or otherwise. Business intelligence
(BI) Web services (Business Intelligence Web
services, 2003) could be embedded in operational
applications like ERP, SCM, CRM (Mello, 2002),
etc. Real time data from RFID (Violino, 2003) and
POS systems could be made available for business
activity monitoring (BAM) using synchronous Web
services based information integration. Web services
could be used for information dissemination over
mobile, hand-held devices, etc. (XInternet
technologies). Finally, information items from
diverse applications running on diverse platforms
could be integrated into an Enterprise level
dashboard using the Web services standards for
enterprise portlets – WSRP (OASIS, 2004).
4 ROAD MAP FOR THE
ADOPTION OF WEB SERVICES
IN THE RETAIL BUSINESS
In this section we propose a road map approach to
application of Web services in the retail organization
and the retail supply chain. In stage 1 (Figure 1) we
propose that the retail organization use Web services
for simple information exchange among enterprise
applications in a limited way requiring minimal
security infrastructure and perhaps behind the
firewalls of the organization. This would require use
of the core SOAP and WSDL standards. In stage 2
the organization having gained experience with this
new technology could move ahead for information
exchange across the firewalls and over the internet.
This could include data exchange across the supply
chain with the trading partners of information not
requiring stringent security aspects like that for
financial transactions. In this stage, the information
could be collected from XInternet technologies
like RFID and POS systems and made available to
the plethora of mobile and hand-held devices over
the internet / intranet on a selective basis. But
before they could do so some form of agreement
on the data standards among the supply chain
partners would need to be worked out. In stage 2,
the retail organization having a well developed
common information model (CIM) in place and
also having gained some experience with tackling
security aspects across the firewalls, the
organization could move ahead towards a scenario
where data having stringent security requirements
like customer profile, financial information, etc.
could be exchanged over the internet. This would
be stage 3. By this stage, the retail organization
would have gained experience with simple, single-
step and secure information exchange across
applications and devices within and across the
firewalls using Web services, paving the way for
more complex scenarios. In stage 4, the Web
services standards for transactions and workflow
and reliable message exchange could be utilized
for accomplishing complex, security critical, multi-
step business transactions and workflow within
and across the firewall (Little et al., 2003).
Stage 1
Stores / Delivery channel
• Stores applications – diverse POS systems
(Tarpley, 2001) could be integrated.
• Shelf management – RFID data on product
uptake and customer purchase behavior inside
the store can be shared online with the stores
managers on their mobile devices.
Retailer back office
• Data from operational applications could be
made available to line managers through
mobile devices, enterprise portals, etc.
• Inputs on historical data from data warehouses
as well as RFID data could be integrated into
Enterprise dashboards/portals for analysis and
planning.
Stage 2
Stores / Delivery channel
• Real time POS and RFID data on sales, could
be sent back to retail office line managers,
field sales agents on their mobile devices,
terminals.
• Latest information on new product release and
price catalogs could be made available to field
