INTRODUCTION
1.1 Background of the Study
This chapter presents the current research in e-government development and online
reverse auctions system, the problem and goals of the study and the significance of the
research. An overview of Malaysias e-government initiatives and Multimedia Super
Corridor MSC! applications, particularly e"erolehan is provided in the chapter together
with an overview of reverse auctions system and e#idding benefits. A description of the
status of e#idding usage and the transactional value are also included.

strategy to response to public e/pectations for enhanced and better public service
delivery. The government is facing increasing e/pectations by the public for fast and
efficient services similar to the 0uality offered by the private sector. The citi%ens who

The global governments effectiveness in delivering online services is trac1ed in a few
studies, for e/ample, e-$overnment initiatives in (( nations were e/amined in the
Accenture Study in ()33. The study finds that leading world governments are modifying
the traditional models of service delivery to a higher level to strengthen their
relationships with citi%ens Accenture, ()33!. e-$overnment relationships with the
sta1eholders can be briefly categori%ed as $overnment-to-Citi%ens $(C!, $overnment-

As seen in Table 3, there are Bleaps between each of the stages. The development
stages of e-government follow several phases from Baccess level that allows citi%ens
and business access to government information@ Binteraction level, which allows
interactions with government through email or download forms@ Btransaction level that
allows users to conduct transactions online@ and Bintegration level, which integrates all
services in different e-government organi%ations and governance. #ased on the models
developed by the researchers, e-government development occurs in stages from

service and reliability, thus hindering collaboration in buyer-supplier relations +miliani
and Stec, ())!. As such, one of the possible reasons of low usage is that the sourcing
officials feel they are no longer contributing to the bidding process as negotiator and
service provider while losing the supplier-buyer relationships normally present in manual
transactions.

&t has been si/ years since e#idding was rolled-out in ())? and based on the statistics
from M';s e"erolehan team pro8ect report, the e#idding system adoption is
e/periencing a low adoption problem www.home.e"erolehan.gov.my, ()3)!. There are
only ?,))) suppliers who are active users out of the appro/imately ),))) suppliers that
are capable of conducting e"erolehan transactions The Star, ( April ()3)!. 2ntil April
()3(, there are a total of 3:,?44 transacting procurement units involving all ministries
and agencies in the "eninsular of Malaysia. >owever the number of transacting
procurement units via e#idding is only 3 transactions out of 3:,?44 transactions of
procurement units. The balance amount was transacted using the manual system
www.home.e"erolehan.gov.my, ()3(!.
The governments approach to address the problem of low adoption of the system are
by using infrastructure and system perspectives increasing &nternet band-with, updating
system and hardware re0uirements!, rather than loo1ing at user acceptance of the
system. The e"erolehan support team only addresses issues related to training,

enablement of government responsible centers, site readiness, user complaints and
revenue generation from the use of the system. The team does not e/amine the factors
that influence e#idding adoption. There has been no empirical study underta1en by the
e"erolehan "ro8ect Team or Commerce ot Com Sdn. #hd. the concessionary! on
e#idding to address the issue of low adoption by the government users. &mplementation
issues were previously mitigated by coordination efforts by the concessionary company
and respective agencies monitored by MAM"2.
The non-adoption of e#idding by government users and their suppliers pose serious
implications for the continuous usage and development of the innovative system. The
suppliers could not participate in e#idding if the system is not chosen by the officials for
transactions. The low rate of adoption by the users indicates inherent officials problem
with e#idding rather than with the suppliers. There is an e/ample where e#idding has
been pointed as the cause for failure in goods and services procurement in a
government agency, due to a mista1e in the transaction caused by ine/perienced and
untrained officials. As a result, the procurement was canceled and re-tendered via
manual transaction 9aporan Audit ()3), page ()3!. This e/ample is one of the possible
causes why officials are not employing e#idding, preferring the alternative manual
procurement methods, although e#idding has been touted as the best tool for cost-
saving for the government.
The losses from the low adoption is in terms of the investment poured into the planning
and development of e#idding which would be going to waste if there is low acceptance
22
8/10/2019 Factors Influencing eBidding (electronic reverse auctions eRAs) Adoption in Malaysian Public Sector
23/234
by the supplier community. &t is a fact that huge investment has been spent on the
development, implementation and maintenance of the system and this problem would
defeat the governments aspirations of increasing efficiency, productivity and
transparency in its operations. The losses are also in terms of the cost to purchase and
develop the technology including the recurring costs to maintain and conduct the
reverse auctions. CommerceotCom Sdn. #hd. CCS#! has invested DM34) million
to develop the e"erolehan system including the e#idding module. ue to the low usage
of the system, the contract between the government and CCS# has been e/tended
until ()3(. A high level of usage by suppliers is important as the business model is fee-
based and depends on the number of transactions and it is important for CCS# to
maintain a high number of transactions for the continuity of their business.
6otwithstanding, the government also loses in terms of e/pected cost saving benefits
from e#idding use if the system is not adopted by the users. The $overnment would be
able to en8oy () to ) percent savings from the operational budget #+D6AMA, ()):!.
;rom the saving, the funding can be channeled to other beneficial development
pro8ects. ;urthermore, the sourcing officials would have to revert to conventional
procurement processes that re0uire the tender documents to be downloaded, printed
and deliberated at tender meetings, which will consume more time and administrative
costs. These processes would have incurred higher operating costs which could be
channeled to other activities in delivering services to the public.

1.11 Pro#"e& State&ent
The low usage reflected the possible inclination of the sourcing officials to procure
goods and services via conventional methods direct purchase or manual 0uotation
system! rather than using e#idding. The use of e#idding by the government users is
voluntary and the sourcing officials have the options, either to conduct a manual
transaction or use e#idding "e1eliling "erbendaharaan, ()):!. The e#idding system
offers compelling benefits to improve administrative efficiency and 0uality of service
delivery. >owever, these benefits may be wasted by officials unwillingness to use the &S
for many reasons that is worth investigating.
The focus of previous e-government studies has always been on the &S adoption by
suppliers rather from the sourcing officials perspective. $eorge ())*! argues despite
increased trainings and promotions, low e-government adoption remains a continuous
problem for the e-government sta1eholders. The system is designed to lessen officials
burden and improve efficiency in public service, as such the 0uestions regarding
government users adoption of e#idding still remain unanswered. Guestions are still
being as1ed by the sta1eholders whether the officials are using e#idding and reasons
the system is not being used. &t is unclear how far is the e#idding system being used by
the officials and what are the users perspectives about the information system. As
such, the research aims are to investigate the constructs that influence officials
adoption of e#idding.

1.1 O#0ect+%e' of the Study
The ob8ectives of this study are to e/amine the factors influencing e#idding adoption by
procuring officials in the public sector and to understand the users behavior in adopting
e#idding. The specific purposes of this study are as followsowever, TAM( only e/plores the basis
of perceived usefulness "2! and ignores perceived ease of use "+'2! construct
which is generalisable. The model is e/tended to TAM which integrates TAM( with "2
determinants to e/plain "+'2 =en1atesh and #ala, ())4!. The additional factors to
TAM are computer self-efficacy, perception of e/ternal control, computer an/iety and
computer playfulness. Computer self-efficacy attribute refers to as an individual
perception whether the user could complete the tas1. "erception of e/ternal control is
42
8/10/2019 Factors Influencing eBidding (electronic reverse auctions eRAs) Adoption in Malaysian Public Sector
43/234
user perception about the e/istence of support for the system. Computer an/iety is
defined as the fear related to using a new technology while computer playfulness is
defined as internal motivation to use a new technology. "erceived en8oyment describes
the feeling when using a system becomes satisfactory. 'b8ective usability is the effort
needed to perform a tas1 =en1atesh and #ala, ())4!.
Although the TAM is more comprehensive in that it increases the "+'2 and "2, the
effects are focused only on the user and not in a much wider perspective. #roader
organisational issues, e.g. the influence of peers and user involvement in decision-
ma1ing may also influence the adoption of a new technology. >owever, many studies
find that TAM is not comprehensive enough in e/plaining users decisions to use the &S.
TAM is used as a base model and additional variables are added according to the
conditions and nature of &S being investigated. ;or e/ample, in a study by
5amarul%aman ())*!, TAM was used as base model and adds other variables such as,
personal cognitive influence. TAM was combined with other adoption models as well, for
e/ample, '& was integrated with TAM in a study on online ban1ing by >ernande% and
Ma%%on ())*!.
&n summary, TAM has been successfully employed in various studies to e/plain
individual acceptance and usage behavior in a wor1ing environment. >owever, there is
a need to e/tend the model by adding additional variables depending on the types of
technologies and environment.

&nnovation iffusion Theory Dogers, 3::! is another user acceptance theory which
has been praised by many researchers as an effective model in e/plaining user
behavior in technology acceptance. '& theory as shown in ;igure , focuses on the
individual characteristics that relate to technology adoption behavior. The '& is a
widely used model in behavioral sciences to investigate adoption of innovations by
individuals 'liveira et al., ()33!. The aim of the '& theory is to comprehend how and
why users either embrace or re8ect innovations Dogers, 3::!. &n 3::, he studied the
characteristics of individuals in terms of openness to innovations, and he developed
'&, which proposes that individuals react differently to change based on a stable
predisposition.
'& focuses on diffusion of innovation process when the new technology is transmitted
through the channels in the social system Dogers, ())!. iffusion of innovations
refers to how new ideas are employed and employed by the users within a specific
setting. According to '&, an innovation will be diffused at an increased rate if it could
be tested before adoption trialability!. &n addition, an innovation offers observable
results observability! and new technology has an advantage relative to other
innovations relative advantage!. Another innovation attributes include comple/ity the
technology is not overly comple/! and whether the innovation is compatible with e/isting
practices and values compatibility!.;ichman, ()))! defines innovation diffusion as the
process when a technology permeates and is adopted across a population.

factors such as, system, service and information 0uality dimensions. The model
limitation is that it cannot provide e/planation as to why the same application system
can be adopted in different ways in various settings Tsi1na1is and 5ouroubali, ())4!.
>ence, it is posited that, by combining all these independent factors it could better
represent factors that determine intention to use or behavioural intention of e#idding.
The effect of users personal innovativeness in the modified 2TA2T framewor1 will also
be investigated by including "&&T construct as a moderating variable. 2TA2T model is a
comprehensive model, but it is unable to include the measure to e/amine individual
traits, such as innovativeness and ris1 ta1ing that contributes towards technology
acceptance Dosen, ())!. #y including "&&T to the integrative 2TA2T and &S Success
Model, it is e/pected to boost the amount of variance e/plained in the adoption behavior
that allows a much wider perspective of user adoption of an &S. The proposed
framewor1 for this research is as shown in ;igure 4.

A research framewor1 is proposed based on the combinations of construct drawn from
both models. The proposed integrative model would provide a more realistic picture of
individual level e#idding adoption by the procuring officials. &n the proposed framewor1,
e#idding adoption is the dependent variable with performance e/pectancy "+!, effort
e/pectancy ++!, social influence S&! and facilitating conditions ;C!, information
0uality &G!, system 0uality SG! and service 0uality S=G! as independent variables.
2ser satisfaction is proposed as the mediator while "&&T is added as the moderator
between "+ and ++ with e#idding adoption.
The adapted 2TA2T model will be tested without two moderator variables, age and
gender. $ender variable is e/cluded due to the environment in the government setting
that did not discriminate the wor1 functions and responsibilities between male or female
officials. #oth genders receive similar training, e/posure and rulings on the use of any
e-government applications. Similarly, age variable is also eliminated from the study due
to the government setting that did not differentiate the wor1 functions and
responsibilities with regards to officials age. =oluntariness variable is e/cluded since
e#idding usage is optional and totally voluntary. A variable for moderating role namely
e/perience, is drawn from 2TA2T. "rior research suggests that increased ine/perience
will lower the influence of effort e/pectancy ++! and social influence S&! on the
adoption of the system =en1atesh et al., ())!. The "&&T is added to e/amine the
mediator effects between "+ and ++ with e#idding adoption. "&&T is posited to have a
moderator role on users perceptions about an innovation Agarwal and "rasad, 3::4!.
69
8/10/2019 Factors Influencing eBidding (electronic reverse auctions eRAs) Adoption in Malaysian Public Sector
70/234
Thus, this study assumes the possibility that e/perience and "&&T have moderating
effects on e#idding adoption by government users.
;or the &S Success Model, the two &S success categories, namely the organi%ational
impact and net benefits variables are e/cluded because it is not the intention of the
study to investigate these two categories, but the behavioural intention category to
adopt e#idding without the various impacts such as societal, individual, and
organi%ational impact of the system. =ariable satisfaction is posited as a mediating
factor between system factors, namely the information 0uality &G!, system 0uality SG!
and service 0uality S=G! and e#idding adoption. The research model put forward in
this study would be tested through the following hypotheses.

adoption of the e#idding is operationalised based on the wor1s of =en1atesh et al.,
())!, namely planning, intention, and predicting the use and actual use. The level of
system use is also 0uantitatively assessed using criteria, for e/ample planning,
intention, actual use, use fre0uency and amount of use of specific features 6elson et
al., ())!.
The study will focus solely on actual adoption because it is more practical to measure
the use of technology instead of intention to use. There is a strong correlation between
intentions to use with actual adoption. TAM e/plains the relationship between intention
to use and actual usage avis, 3::!. #ehavioural intention is found to be a valid
predictor of usage and adoption Sun and Jhang, ())!. As such it is ade0uate to test
only one of the variables because of the positive significant relationship between these
variables to each other. &t is posited that adoption is influenced by performance
e/pectancy "+!, effort e/pectancy ++!, facilitating conditions ;C!, social influence
S&! and system 0uality factors with three moderators, "&&T, voluntariness and
e/perience mediated by satisfaction.

(.-.. Effort e?)ectancy
+ffort e/pectancy refers to the degree of ease of system usage. The construct is similar
to TAMs perceived ease of use which is confirmed by 2TA2T authors. &n TAM and
TAM(, the effort e/pectancy is represented as perceived ease of use in '&. The TAM
factors include ease of use, ease of achieving level of e/pertise and easily
understandable =en1atesh et al., ())!.
+ffort e/pectancy construct is posited to be an antecedent of behaviour adoption and
use. "ar1 et al., ())*! find that effort e/pectancy significantly affects user adoption of
mobile service. &n Carlsson et al., ())?! study, the authors support the relationship
between effort e/pectancy and adoption. The authors contend that effort e/pectancy
has significant influence on the behavioural acceptance of the service. "revious
research also supports the contention that lesser effort is re0uired to learn and use the
system will ultimately influence its acceptance $efen and Straud, ()))!.
&n the study, effort e/pectancy is the belief that using e#idding would assist the
procuring officials to gain certain advantages for e/ample, improve 8ob performance and
increase productivity in their wor1 environment. As officials increasingly become used to
a new technology, the effort needed to use e#idding will decline. The more the officials
believes that the system is easy to use and help them become very s1illful in using the
system the more the inclination to use e#idding. &t is posited that the officials will use
e#idding if the system is easy to use, easy to operate and learn and re0uire less effort

/.3.1 De'cr+)t+%e Stat+'t+c'
escriptive statistics is employed in order to organise the results which covers the tests
of fre0uencies, mean and standard deviation. ;re0uency distribution enables
researchers to view the entire responses to the 0uestionnaire. Mean is used to measure
average response by adding all the numbers and dividing by the number of cases.
Standard deviation shows the distribution scores from the mean value ;in1, ())4!.
/.3. Inferent+a" Stat+'t+c'
&n the study, inferential statistics is used to enable the results obtained from samples to
be generalised. Structural +0uation Modelling S+M! and AM'S software are used to
e/amine the measurement model ade0uacy and structural model goodness-of-fit $o;!
including the hypotheses testings.
/.3.( Structura" Euat+on ode"+ng 6SE9
The study employs the Structural +0uation Modeling S+M! techni0ue to test the
relationships among the variables in the model. The method involves multiple
regression analysis of factors among a single measured dependent variable and a
group of predictors 2llman ())*!. >air et al., ())?! argued that S+M is able to
e/amine two types of models, i.e. the measurement model that represents the theory
and the model which represent the latent factors. A structural e0uation modeling S+M!
employs multivariate analyses and will show relationships between constructs and the
103
8/10/2019 Factors Influencing eBidding (electronic reverse auctions eRAs) Adoption in Malaysian Public Sector
104/234
causal dependencies between endogenous and e/ogenous variables >air et al., ())?!.
The S+M also allows two groups comparisons which ma1es it suitable for testing the
hypotheses of the research. Therefore, S+M is selected in this study to maintain
parsimony in the proposed model while benefiting from its strength in testing the
research hypotheses.
The study uses AM'S version ? to e/amine the relationships between the independent
variables "+, ++, S&, ;C, SG, &G, S=G!, moderator variables "&&T and e/perience!
and one mediator satisfaction! and behavioural actual use of e#idding service. There
are two main reasons behind the decision to adopt this software. ;irst, the software is
available in the graduate school resource centre, as such it is accessible for the
analysis of data. Second, AM'S is rarely employed in previous empirical and
conceptual research of user acceptance Tong, ())*!.
Structural +0uation Modeling S+M! in AM'S involves drawing a circle and arrow path
diagram. AM'S is easy to learn and use and it is capable of analysing many goodness-
of-fit measures. AM'S also offers fle/ibility and ability to analyse numerous linear
models $arson, ()):!. The data will be analysed with descriptive and inferential
statistics tests. The following statistical methods are used in this study to organi%e the
datae argued that by reporting all goodness-of-fit
measures, it implies that the researcher is on a fishing e/pedition. >owever,

tests are chi-s0uare@ $oodness-of-;it &nde/ $;&!, 6ormed ;it &nde/ 6;&!,

Chi-s0uare Q(! is the most popular goodness-of-fit test used for S+M $arson,
()):!. AM'S outputs list chi-s0uare as chiPRCM&6. The model chi-s0uare
values tend to decrease better fit! when more paths are inserted or created in a

that the Q( value will be less influenced by the si%e of the sample 2llman,
())*!. Delative E( is listed in AM'S as DAT&' P CminFdf, and a relative E(
value of or less is considered as acceptable Tong, ())*!.
Comparative ;it &nde/ C;&! is another measurement for $oodness-of-;it test.
C;& is used to measure the model fit improvement compared to a null model
$arson, ()):@ Tong, ())*!. AM'S lists C;& as C;&PRcfi Tong, ())*!. C;& value

6ormed ;it &nde/ 6;&! is an alternative inde/ of C;& Tong, ())*!. 6;& ranges

desirable, but the researcher has to re-specify the model if 6;& value is below

Tuc1er 9ewis ;it &nde/ T9&! is another incremental fit inde/ similar to 6;&

Tong, ())*!. T9& value close to 3 or T9& value ).:) shows a good model fit,
while T9& value below ).:) shows the need to re-specify the model Tong,

A moderating variable is the construct which has a strong contingent effect on the
relationships between the predictor and the outcome variables. A contingent effect
indicates an e/istence of another variable that influences the relationships between the
predictor and the outcome Se1aran ())!. The moderating effect can be tested using
multiple-group analysis in AM'S which is able to estimate two or more groups
simultaneously Arbuc1le, ())!.
According to ;ra%ier et al., ())! moderating variable is present between predictor and
criterion variable. &t modifies the correlation in two ways by influencing the changes in
the correlation strength or the changes in the causality direction either negative or
positive!. The moderating hypothesis will e/amine the paths between the predictor and
the outcome variables, in terms of magnitude andFor directions. ;or e/ample, any
difference across the groups indicates that the predictor influence toward outcome
variable is moderated by that construct.
&n the case of the study, two moderators "&&T and e/perience! were tested to see
