9.351 Systems Analysis & DesignSystem Implementation1 System Implementation Phases Coding (in Waterfall SDLC, not part of design stage) Testing (slide) Installation (4 types - slides) Documentation User Training User Support Implementation Challenges (Denver International Airport) System adoption

9.351 Systems Analysis & DesignSystem Implementation2 software hardware (network including) software: developers’ tests: inspection & walkthrough testing pieces & wholes debuggers user tests – alpha, beta Testing

9.351 Systems Analysis & DesignSystem Implementation3 system documentation: external (diagrams studied in the course) internal (embedded in code; “Hungarian at Microsoft) user documentation – how to use the system manuals, online tutors & knowledge bases, help faculties Documentation

9.351 Systems Analysis & DesignSystem Implementation4 User Training & Support User training is critical for system adoptions and success (e.g., groupware – need to be “domesticated”) Training in systems use and other computing & info management issues Importance of knowledgeable colleagues (“communities of learning”) Support through Information Center Help desk

9.351 Systems Analysis & DesignSystem Implementation5 Implementation Challenges: Denver International Airport Case DIA opened in Oct. 1995; designed to be largest U.S. airport Automated baggage handling system delayed opening for 16 months and caused $2 billion spending over budget Players & project escalation System: computer-driven with mechanical parts, to route inbound and outbound luggage with minimum human input and deliver luggage information to airlines, airport clerks and passengers Technical difficulties Outcome: Project deescalated, 1 concourse partly automated, 2 redone in classical manner

9.351 Systems Analysis & DesignSystem Implementation6 Implementation Challenges – Any System Securing resources for system development (Challenge: “Pork Barrel” syndrome; stretching budget between competing projects) Keeping agreement among stakeholder on goals of the system (Challenge: “Not invented here” syndrome) Preserving key system requirements through development project (Challenge: complicating requirements, dissipating attention energy & resources)

9.351 Systems Analysis & DesignSystem Implementation7 System adoption User’s interest (contribution to work & personal/group agenda) System characteristics (ease of use, reliability/trust in system) Management incentives (allocating time for training, stimulating use)
