- 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.

- Results 06/05/201119
- Slide 20
- Results Final Mode 06/05/201120
- 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
