erp selection criteria importance
the reason that companies with highest revenue
(in the year 2006) participated in the research.
In large companies most frequently used ERP
system is SAP (29,4%), MS Dynamics NAV
(13,7%) and Perftech Largo (9,8%) from local
ERP system provider. In most of medium-sized
companies use Slovene providers's Perftech Largo
system (16,7%), followed by SAP and MS Dynam-
ics NAV (both 12%). This is followed by usage
of ERP systems from Slovene provider Datalab
Pantheon (8,3%). Only 7,8% of large and 4,2% of
medium-sized companies reported to use in-house
developed ERP systems. In small companies the
most commonly used ERP system is MS Dynam-
ics NAV (30%), followed by Datalab Pantheon
and in-house developed ERP systems (both 20%).
In 33.8% of large companies have stable use
of ERP system for some years. ERP system has
just been recently implemented in 23.5% of large
companies. Medium-sized companies in most
cases have recently implemented ERP systems
(48.6%). In 25.7% of medium-sized companies
have stable use of ERP system for some years.
Most of small companies have only recently
implemented ERP system (40%). 32% of small
companies are in the stage of considering ERP
system implementation.
Detail representation of characteristics of par-
ticipated companies in the research is presented
in the table 1.
In the Tables 2, 4, 6, and 8, the importance of ERP
selection criteria is presented by mean values,
ordered from very high importance to very little.
The importance of ERP selection criteria was
investigated by 5 point Likert scale, where 1 is of
very little importance and 5 is of very high impor-
tance. The data are analyzed and presented for all
companies together as the company size impact
on importance of ERP criteria was separately
investigated by ANOVA multivariate approach.
ANOVA analysis results are presented in the
section 3.3. Correlation matrices for the groups
of criteria are provided in tables 3, 5, 7, and 9.
Table 2 presents the importance of ERP benefits
criteria. The most important ERP benefits criteria
are integrated and better quality of information
(4,59), business process improvement (4,25), im-
proved service levels and quality (4,21), enhanced
decision making (4,11), reduced cycle times and
increased customer satisfaction (4,03).
Table 3 presents correlation matrix for ERP
benefits criteria. The results of Cronbach alpha
test show that ERP benefits criteria are internally
consistent (Cronbach's alpha is 0.774118, stan-
dardized Cronbach's alpha is 0.773752).
Table 4 presents importance of system quality
criteria. The most important criteria in this group
are system reliability (4,61), system functionality
(4,37), system usability (4,31), system flexibility
(4,22) and system interoperability (4,09).
