Outline • Abstract • Introduction • Background • Research Methods • Results • Discussion • Conclusion
Abstract • The use of these software developmentinnovationsis not widespread,further exacerbating the problems in industry. • Consistent with prior studies,anexogenous variable,training,is added to the original Technology Acceptance Model (TAM).
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
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.
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.
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.
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.
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.
Background • Theoretical Model Usefulness Training Use Ease of Use
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.
Background • Theoretical Model • Training . • Traininghas proven to be an important determinant in explaining usage for innovations. • further segmented training into external and internaltraing.
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 .
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.
Research Methods • Sample • Pass three Months introductedthe 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.
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
Research Methods • Sample • 85developers 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 • Measurement model
Results • Final Mode
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
Discussion • Interpretation of result
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.
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
Conclusion • Training affected ease of use • Ease of use was related to usefulness • Ease of use was the major determinant of usage
