Abstract The use of these software development innovations is
not widespread,further exacerbating the problems in industry.
Consistent with prior studies,an exogenous variable,training,is
added to the original Technology Acceptance Model (TAM).

Slide 4
Abstract Result from a study of one organizations early use of
a custom-built software development tool (SDT) produced the
following significant relationships: training ease of use Ease of
use usefulness Ease of use usage 06/05/20114
Slide 5
Introduction In addition to a growing two or four year
application backlog,research indicates that only about 25% of all
projects are successfull. Computer-aided Software Engineering
(CASE) is the use of computer-based support in the software
development. 06/05/20115
Slide 6
Introduction CASE tools have received a large amount of
interest dut to their relative over-hype and under-use. TAM :
technology acceptance model. CASE tool : custom-built tool.
Training : an exogenous variable. 06/05/20116
Slide 7
Background Theory Innovation proccess ( assimilation) : Parties
become aware of the innovation The innovation is
introduced,affected parties decide to adopt or reject the
innovation The innovation (if adopted) is used and on-going
decisions are made regarding the continued use of the innovation.
06/05/20117
Slide 8
Background Theory TAM,originated by Davis(1989). Asserts that
perceived usefulness and perceived ease of use (EOU) are major
determinants of intentions to use. Training : an exogenous
variable. User characteristics, system characteristics.
06/05/20118
Slide 9
Background Prior Research in SDT Use CASE tools are usually the
focus of software development innovations research. Research
focusing on the adoption of software development tools is generally
lacking. 06/05/20119
Slide 10
Background Theoretical Model 06/05/201110 Training Usefulness
Ease of Use Use
Slide 11
Background Theoretical Model Perceived Ease of Use. Defined :
degree to which the prospective user experts the target system to
be free of effort. Perceived Usefulness. Defined : the prospective
users subjective probability that using a specific application
system will increase his or her job performance. 06/05/201111
Slide 12
Background Theoretical Model Training. Training has proven to
be an important determinant in explaining usage for innovations.
further segmented training into external and internal traing.
06/05/201112
Slide 13
Research Methods Instrument Development Examine determinants of
use. A seven-point Likert scale : 1 = strongly disagree, 7 =
strongly agree Measure ease of use and usefulness. A single item(
4-point scale) indicating depth of use. 06/05/201113
Slide 14
Research Methods Sample The survey instrument was administered
to a group of software developers at the selected organization(a
multi-billion dollar, publicly held organization). 200 IT people,
of which 138 were application developer. 06/05/201114
Slide 15
Research Methods Sample Pass three Months introducted the new
SDT Lotus Notes. Training was provided in-house on how to use the
Lotus Notes interface and associated templates. Use of the tool not
mandatory. 06/05/201115
Slide 16
Research Methods Sample 85 / 138 application developers
participated in the study for a response rate of 62%. 54 were
male,22 were female, 9 did not report their gender. Average of age
: 33, Average of development experience : 9.3 years Average of had
been with Company : 3.6 years 06/05/201116
Slide 17
Research Methods Sample 85 developers responding to the survey.
72 developers were aware of the tool. 60 developers were aware and
used the tool. 60 developers actually used the tool.

Slide 21
Discussion Three significant relationships were found between
training and ease of use between ease of use and usefulness Between
ease of use and usage Significant relationships were not detected
between training and usefulness between usefulness and usage

Slide 22
Discussion Interpretation of result 06/05/201122
Slide 23
Discussion Implications and Future Research Training was the
only exogenous variable investigated and it prove to be important.
Use was relatively low in this study,with EOU its main determinant.
EOU is enough to get developers to begin using the tool, but not
enough to warrant coutinued use. 06/05/201123
Slide 24
Discussion Implications and Future Research Other variables
that should be considered in future studies. Innovation
characteristics, organizational structure, management support,
organizational goals, subjective norm, among others
06/05/201124
Slide 25
Conclusion Training affected ease of use Ease of use was
related to usefulness Ease of use was the major determinant of
usage 06/05/201125
