Activities to implement new information system

Sometimes called "methodology"

When inflexible, system development process is called

This slows development of new IS, but allows to share what and how implemented

proposal to use IS to solve problem

cost benefit analysis, initial schedule, charter or project agreement

defining the broad problem and identifying causes

planning new system

what the user sees, defines database

database, program specifications, hardware

marclogic

physical design specs translated into software

written description of system for users and tech staff

tasks and schedules for training, conversion, testing. anticipating and dealing with resistence

do this because IS usually not intuitively obvious

testing each program in system by itself

testing system as a whole

full system, organization at once

start with a small part of organization

one subsystem, then another

run old and new simultaneously

transfer of data from old files to new files in new formats

fixing errors

adding new features

two methodologies to analyze and design IS

techniques are step by step, will defined.

focus on modeling processes or actions that manipulate data

separate data from processes

represents processes and flow of data between them

breaking processes into successive layers of detail called high level and lower level views
