Unformatted text preview: 1 Chapter 3 Systems Development Cycle and Project Conception Project Management for Business, Engineering, and Technology Systems Development Cycle Systems Life Cycle It’s useful to think of a project end-item as a system that moves through phases of a life cycle Life Cycle Stages: Natural Organisms All living organisms follow life-cycle stages Conception Birth Growth Maturity Decline Death Life Cycle Stages: Human-Made Systems All human-made systems follow this cycle 1. Development/Installation 2. Operation Termination Life Cycle Stages: System Life Cycle 1. Development/Installation conception, birth, and growth (Project) 2. Operation maturity and decline Termination Enhancement/Replacement • For a human-made system termination is not inevitable. • System is kept alive through enhancement/ replacement. • Thus, every human-made system begins as a project and often ends with the start of a new project. Systems Development Cycle Expanded version of the system life cycle: The Systems Development Cycle (SDC) 2 Systems Development Cycle Phase B: Definition phase Project definition System definition User and system requirements Phase C: Execution phase Design stage Production/build stage Fabrication Testing Implementation stage Training Acceptance tests Installation Termination Phase A: Conception phase Initiation stage Feasibility stage Proposal preparation Phase D: Operation phase System maintenance and evaluation System Improvement System termination (To Phase A: repeat cycle) Key Actors (Stakeholders) in SDC Customer/Client Party for whom project is being done Pays for project Has needs and requirements to be met User Party that operates or is beneficiary of project end-item Might be same as customer, might not If different, important to differentiate user from customer System Development Organization (SDO) Party that performs work for customer aka developer, contractor, consultant Key Actors in SDC (cont'd) For most projects, customer and developer are separate organizations or separate units within same organization. Sometimes they are same, but we will treat them as separate Key Actors in SDC (cont'd) Customer and contractor/developer each are organizations: Doers Customer Org’n (System Development Org’n) Top mgt.
