A Study on the Effect of the Introduction

Characteristics of Cloud Computing Services on the

Performance Expectancy and the Intention to Use: From

the Perspective of the Innovation Diffusion Theory

Jae Su Lim*, Jay In Oh**

Our society has long been talking about necessity for innovation. Since companies in particular need

to carry out business innovation in their overall processes, they have attempted to apply many innovation

factors on sites and become to pay more attention to their innovation.

In order to achieve this goal, companies has applied various information technologies (IT) on sites as a

means of innovation, and consequently IT have been greatly developed. It is natural for the field of IT to

have faced another revolution which is called cloud computing, which is expected to result in innovative

changes in software application via the Internet, data storing, the use of devices, and their operations. As

a vehicle of innovation, cloud computing is expected to lead the changes and advancement of our society

and the business world.

Although many scholars have researched on a variety of topics regarding the innovation via IT, few studies

have dealt with the issue of could computing as IT. Thus, the purpose of this paper is to set the variables

of innovation attributes based on the previous articles as the characteristic variables and clarify how these

variables affect โ€Performance Expectancyโ€ of companies and the intention of using cloud computing.

The result from the analysis of data collected in this study is as follows. The study utilized a research model

developed on the innovation diffusion theory to identify influences on the adaptation and spreading IT for

cloud computing services. Second, this study summarized the characteristics of cloud computing services

as a new concept that introduces innovation at its early stage of adaptation for companies. Third, a theoretical

model is provided that relates to the future innovation by suggesting variables for innovation characteristics

to adopt cloud computing services. Finally, this study identified the factors affecting expectation and the

intention to use the cloud computing service for the companies that consider adopting the cloud computing

service.

As the parameter and dependent variable respectively, the study deploys the independent variables that

are aligned with the characteristics of the cloud computing services based on the innovation diffusion model,

and utilizes the expectation for performance and Intention to Use based on the UTAUT theory. Independent

variables for the research model include Relative Advantage, Complexity, Compatibility, Cost Saving,

Trialability, and Observability. In addition, 'Acceptance for Adaptationโ€™ is applied as an adjustment variable

to verify the influences on the expected performances from the cloud computing service.

The validity of the research model was secured by performing factor analysis and reliability analysis. After

confirmatory factor analysis is conducted using AMOS 7.0, the 20 hypotheses are verified through the analysis

of the structural equation model, accepting 12 hypotheses among 20.

For example, Relative Advantage turned out to have the positive effect both on Individual Performance

and on Strategic Performance from the verification of hypothesis, while it showed meaningful correlation

to affect Intention to Use directly. This indicates that many articles on the diffusion related Relative Advantage

as the most important factor to predict the rate to accept innovation. From the viewpoint of the influence

on Performance Expectancy among Compatibility and Cost Saving, Compatibility has the positive effect

on both Individual Performance and on Strategic Performance, while it showed meaningful correlation with

Intention to Use.

However, the topic of the cloud computing service has become a strategic issue for adoption in companies,

Cost Saving turns out to affect Individual Performance without a significant influence on Intention to Use.

This indicates that companies expect practical performances such as time and cost saving and financial

improvements through the adoption of the cloud computing service in the environment of the budget squeez-

ing from the global economic crisis from 2008. Likewise, this positively affects the strategic performance in

companies.

In terms of effects, Trialability is proved to give no effects on Performance Expectancy. This indicates that

the participants of the survey are willing to afford the risk from the high uncertainty caused by innovation,

because they positively pursue information about new ideas as innovators and early adopter. In addition,

they believe it is unnecessary to test the cloud computing service before the adoption, because there are

various types of the cloud computing service.

However, Observability positively affected both Individual Performance and Strategic Performance. It also

showed meaningful correlation with Intention to Use. From the analysis of the direct effects on Intention to

Use by innovative characteristics for the cloud computing service except the parameters, the innovative

characteristics for the cloud computing service showed the positive influence on Relative Advantage,

Compatibility and Observability while Complexity, Cost saving and the likelihood for the attempt did not

affect Intention to Use.

While the practical verification that was believed to be the most important factor on Performance

Expectancy by characteristics for cloud computing service, Relative Advantage, Compatibility and Observabil-

ity showed significant correlation with the various causes and effect analysis. Cost Saving showed a significant

relation with Strategic Performance in companies, which indicates that the cost to build and operate IT

is the burden of the management. Thus, the cloud computing service reflected the expectation as an alter-

native to reduce the investment and operational cost for IT infrastructure due to the recent economic crisis.

The cloud computing service is not pervasive in the business world, but it is rapidly spreading all over

the world, because of its inherited merits and benefits. Moreover, results of this research regarding the diffusion

innovation are more or less different from those of the existing articles. This seems to be caused by the

fact that the cloud computing service has a strong innovative factor that results in a new paradigm shift

while most IT that are based on the theory of innovation diffusion are limited to companies and organizations.

In addition, the participants in this study are believed to play an important role as innovators and early

adapters to introduce the cloud computing service and to have competency to afford higher uncertainty

for innovation. In conclusion, the introduction of the cloud computing service is a critical issue in the business

world.
