Chapter 17
ď‚· Preventive maintenance makes system changes to reduce the chance of
future system failure.
ď‚· A project is a temporary activity a company undertakes to create a unique
product, or result.
ď‚· Parallel Implementation: uses both the legacy system and new system until
all users verify that the new system functions correctly
ď‚· Plunge Implementation: discards the legacy system and immediately
migrates all users to the new system
ď‚· Pilot Implementation: assigns a small group of people to use the new system
until it is verified that it works correctly; then the remaining users migrate to
the new system
ď‚· Phased Implementation: installs the new system in phases (for example, by
department) until it is verified that it works correctly.
ď‚· The phases in the systems development life cycle: Planning, Analysis, Design,
Development, Testing, Implementation/Maintenance.
ď‚· The testing phase brings all the project pieces together into a special testing
environment to eliminate errors and bugs and verify that the system meets
all the business requirements defined in the analysis phase.
ď‚· Workshop training is held in a classroom environment and led by an
instructor.
ď‚· Conversion is the process of transferring information from a legacy system to
a new system.
ď‚· Requirements management is the process of managing changes to the
business requirements throughout the project.
ď‚· Business requirements are specific business requests that system must meet
to be successful, so the analysis phase is critical because business
requirements drive the entire systems development effort.
ď‚· The project plan is a formal, approved document that manages and controls
the entire project.
ď‚· Five primary reasons why projects fail: Changing technology, balance of the
triple constraints, skipped SDLC phases, the cost of finding errors, unclear or
missing business requirements
 A help desk is the best way to support users and respond to users’ questions.
ď‚· Off-the-shelf application software supports general business processes and
does not require any specific software customization to meet the
organization’s needs.
ď‚· Alpha testing: assess if the entire system meets the design requirements of
the users.
ď‚· Development Testing: test the system to ensure it is bug-free
ď‚· Integration Testing: verify that separate systems can work together, passing
data back and forth correctly
ď‚· System testing: verify that the units or pieces of code function correctly when
integrated
