2. Outline Abstract Introduction Background Research Methods Results Discussion Conclusion 06/05/20112

3. 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). 06/05/20113

4. Abstract Result from a study of one organization’s 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

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

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

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

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

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

10. Background Theoretical Model 06/05/201110 Training Usefulness Ease of Use Use

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 user’s subjective probability that using a specific application system will increase his or her job performance. 06/05/201111

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

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

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

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

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

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. 06/05/201117

18. Results Measurement model 06/05/201118

19. Results 06/05/201119

20. Results Final Mode 06/05/201120

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 06/05/201121

22. Discussion Interpretation of result 06/05/201122

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

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

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
