Factors Affecting Systems Development Success
• Degree of Change– Continuous Improvement versus Reengineering– Managing change
Computer-Aided Software Engineering (CASE) Tools
Automate many of the tasks required in a systems development effort and enforce adherence to the SDLC, thus instilling a high degree of rigor and standardization to the entire systems development process
• Upper-CASE tools - CASE packages that focus on activities associated with the early stages of systems development.
• Lower-CASE tools - focus on the later stages of systems development and are capable of automatically generating structured program code.
• Integrated-CASE tools - provide links between upper- and lower-CASE packages.
Requirements Analysis
• Asking directly• Critical success factors (CSFs)• The IS plan• Screen and report layout
Summary
• Systems development team - of stakeholders, users, managers, systems development specialists, and various support personnel
• Five phases of the traditional SDLC - investigation, analysis, design, implementation, and maintenance and review
• Systems investigation participants - stakeholders, users, managers, employees, analysts, and programmers
