MIS 3510 Systems Analysis Design Fall 2018 SUMMARY

MIS 3510 Systems Analysis & Design Fall 2018 SUMMARY 1

MIS 3510 - Systems Analysis & Design Summary FALL 2017 • Different views of information system (IS) • Structural view (data, hardware, software/application, procedures) • Functional view (input-process-output) • Object view • Services view (client-server model: user interface, data storage, data processing/functionality) • Services Oriented Architecture (components) 2

The Emphasis of the Course Systems analysis l Analyzing organizational tasks/processes either supported or not supported by electronic or preelectronic IT • Identifying system requirements for the to-be system • Deliverable: Logical design of the current and future state of an IS System design • What specifically needs to be made/changed regarding a system’s functionality, data, & user interface • Methods used: Exercises, homework, term paper, lab 3

Challenges in Systems Analysis • What is in the system? Where is system boundary? • Process thinking (Activity Diagram) vs. Non-process thinking (Use Case Diagram) • Data modeling: what is class, attribute, association? Focus on details and completeness. • Capability to toggle between big and small picture • Capability to read (and sometimes write) different notation schemes. 5

Some Highlights • MIS Perspective emphasized: - IS support user and organizational purposes - System examples rooted in specific organizational contexts - Various systems studied (TPS, MIS) • Technical perspective: - Vocabulary, analytical skills, graphical expression - Hands-on learning: i. Grafx, Visio, MS Project 6

Conclusion • MIS 3510 provided a solid introduction into analytical skills for understanding IS and their embeddedness in organization. • MIS 3510 is useful for any specialization in systems area (system analyst, business analyst, system developer, data analyst, network jobs, database jobs). • MIS 3510 prepares you for MIS 3500 (DBMS) and analytics. 7
