CHAPTER 11: Managing Systems Implenetation
software quality
assurance
software engineering
capability maturity model
capability maturity model integration
process improvement
international organization
standardization
agile application
development
dev tea constant communication with the customer
extreme programming(XP) is one of newest agile methods
XP
user story
release plan
iteration cycle
test driven design
structured application
development
structure chart
control module
module
subordinate module
data couples
cohesion & coupling
tightly coupled
loosed coupled
structure chart
review DFDs
identify modules & relationship
add couples, loops and condition
analyze the structure chart
and data dictionary
object-oriented
application development
OOD
characteristics of object-oriented
application development
implementation of object-oriented design
object-oriented cohesion&coupling
classes: loosely coupled
methods: loosely coupled and
highly cohesive
coding
programming environment
generating code
can generate editable program
code directly from macros, keystrokes/ mouse actions
testing system
unit testing
integration testing
system testing
documentation
program documentation
system documentation
operation documentation
user documentation
effective online documentation important productivity tool
written documentation material also valuable
operational &
test environtment
include hardware& software configurtaion& setting, system utilities, telecomunication resource
training
plan
3 main group : user, manager, IT staff
vendor training
sysetm includes purchase of software/hardware then vendor supplied training is one feature that should investigate in the RFP & RFQ
give best return on training
webinars,podcast,
tutorials
webcast
subscribers
tutorials can be developed by software vendor/ company IT team
outside training
resources
training consultan, institude & firm provide standardize/ customized training packages
data conversion
strategies
old system might be capable exporting data for new system
if standard format not available, must develop program to extract data&convert it
often requires additional data items
security & controls
ensure all system control measures in place & operational to project data from unaothorizes access
some error will occur
system changeover
direct cutover
involve more risk
parallel operation
easier to verify that new system
working properly
pilot operation
combination of parallel operation&
direct cutover method
phase operation
less expensive
