2. INTRODUCTION
• Impact of eBusiness technologies on operational performance: The
role of production information integration in the supply chain,
Devaraj et al. (2007)
• An empirical study of the impact of e-business technologies on
organizational collaboration and performance, Sanders (2007)
• The impact of e-business on capital productivity: An analysis of the
UK telecommunications sector, Martínez-Caro & Cegarra-Navarro
(2010)
• Investigating the impact of e-business applications on supply chain
collaboration in the German automotive industry, Wiengarten et al.
(2013)

Production Supply
information chain
integration
• Do eBusiness technologies have a significant impact on
supply chain performance?
• Does production information integration constitute an
important link in the pathway from eBusiness technology
to supply chain performance?

Previous studies New contributions
Firm performance is not directly linked But there is a mediator factor, which is
with e-Business capability, Zhu and the production information integration
Kraemer (2002)
Supply chain integration intensity  Supplier integration + Customer
competitive capabilities  positive integration  Operational
business performance, Rosenzweig et performance
al. (2003)
4 Web-based supply chain integration First theoretical framework of supply
strategies that are linked to chain integration that addresses the
operational performance, Frohlich and effects of e-business capabilities,
Westbrook (2002) production information integration
and operating performance

Using empirical data
• How does the use of e-business technologies impact on
organizational collaboration and organizational performance?
• What is the difference between inter- and intra-organizational
collaboration impact?

7. Sanders (2007) (II)

8. Sanders (2007) (III)
• Contributions
1. An empirical test of theorectical assumptions in the
literature of the influence of EB technologies on collaboration.
2. Managers should focus on EB technologies that promote
collaboration. It validates and confirm the important role of
internal collaborations.
3. It supports the finding that inter-firm collaboration
influences intra- organizational collaboration.

9. Martínez-Caro & Cegarra-
Navarro et al. (2010)
• Which EB technologies are more likely to lead to a boost in
productivity?
Groupware
applications Capital
Collective Productivity
Systems
The theoretical background of this model is based on Sanders’
previous research.

10. Martínez-Caro & Cegarra-
Navarro et al. (2010) (II)
• Results and contributions
To improve CP, managers need to provide and support a context
with two dimensions:
1. Groupware applications and
2. Collective systems
The firm size is not important to improve CP through groupware
and collective systems.

11. Wiengarten et al. (2013)
Multiple dimensions of EB: Do all EB applications impact directly and positively
on supply chain collaboration?
Is the buyer-supplier collaboration the mediating variable between EB
applications and operational performance?
Different EB Multiple

Wiengarten bases his research of Devaraj’s and Sanders’ previous works.

12. Wiengarten et al. (2013) (II)
The deconstruction of EB into multiple constructs will enable the
measurement of EB value to be more accurately assessed.
The direct impact of EB-enabled collaboration to facilitate
interaction and integration and its impact on operational
performance adds to the body of knowledge within the larger
research field of supply chain collaboration.
