Q

Brooks’ Law

A

states that adding more people to a late project makes it later.

-The famous adage that states: Adding more people to a late project makes the project later. Brooks’ Law is true not only because a larger staff requires increased coordination, but also because new people need to be trained. The only people who can train the new employees are the existing team members, who are thus taken off productive tasks. The costs of training new people can overwhelm the benefit of their contributions.

Q

Parallel Installation

A

the new system/business processes run parallel with the old one until the new system is tested and fully operational.
-parallel installation is expensive because the organization incurs the costs of running both the existing and the new system/business processes.

-A type of system conversion in which the new system runs in parallel with the old one and the results of the two are reconciled for consistency. Parallel installation is expensive because the organization incurs the costs of running both systems, but it is the safest form of installation.

Q

Phased Installation

A

the new system/business processes are installed in phases across the organization(s).

-A type of system conversion in which the new system is installed in pieces across the organization(s). Once a given piece works, then the organization installs and tests another piece of the system, until the entire system has been installed.

Q

Pilot Installation

A

the organization implements the entire system/business processes on a limited portion of the business.

-A type of system conversion in which the organization implements the entire system on a limited portion of the business. The advantage of pilot implementation is that if the system fails, the failure is contained within a limited boundary. This reduces exposure of the business and also protects the new system from developing a negative reputation throughout the organization(s).

Q

Plunge Installation

A

the organization shuts off the old system/business processes and starts the new one.

-A type of system conversion in which the organization shuts off the old system and starts the new system. If the new system fails, the organization is in trouble: Nothing can be done until either the new system is fixed or the old system is reinstalled. Because of the risk, organizations should avoid this conversion style if possible. Sometimes called direct installation.
