CIS 210 Systems Analysis and Development Week 9 Part I System Implementation,

Objectives Upon completion of part I you will be able to: –Understand and be able to explain the concepts related to coding and testing during system implementation –Understand and be able to create a test plan –Understand and be able to explain the concepts related to four installation strategies: direct, parallel, single location, and phased installation –Understand and be able to creating a training plan for users during system implementation –Understand and be able to explain the common issues related to system implementation –Understand and be able to explain the concepts related to factor and political models of the implementation process

Overview Implementation Phase –Very Expensive –Not a mechanical process –Shaped by people –History –Politics –Environmental demands –Testing –Installation –Documentation –Training

System Implementation Coding, Testing and Installation –Process –Deliverables Code, Program documentation Test scenarios and test data Results of program and systems testing User guides A user training plan A installation and conversion plan Documentation, Training, and Support –Process –Deliverables System documentation User documentation Classes Tutorials Training materials Computer-based training aids A help desk Online help Bulletin boards and other support mechanisms

Software Application Testing Overview –Purpose of tests –Master test plan –Testing managers –Testing specialists Types of Testing –Inspection –Walk-through –Desk checking –Unit testing –Integration testing –System testing –Stub testing

Software Application Testing The Testing Process –Confirm requirements met –Testing must be planned –Test case Combining Coding and Testing –Test soon after code is generated –Acceptance testing Alpha Beta System audit

Installation Approaches to Installation –Direct –Parallel –Single-location –Phased Planning for Installation –Software –Hardware –Documentation –Work methods –Offices

Documentation Types of Documentation –System Design specifications Internal workings Functionality Internal system documentation External system documentation –User Written or visual How system works How to use it

Training and Supporting Users Training Topics –System use –Computer concepts –IS concepts –Organizational information –System management –Installation Methods of Delivery –Tutorials –Courses –Computer-aided instruction –Interactive training manuals –Resident expert –Software help –Externals sources Support –Automated –Help desk

Organizational Issues Characteristics of success –Conventional wisdom Management support Involvement of users –Factors models Ginzberg –Commitment to change and the project –Extent of project definition and change –User expectations Lucas –User’s personal stake –System characteristics, –User demographics –Organizational support –Performance –Satisfaction –Political models Self-interested goals Power distribution
