____________ is a hierarchical representation of the activities in a project.

A prototype

______________ is a simplified, experimental model of an information system.

technological feasibility is not met

A company tested facial recognition software which would be used to authenticate users of its information systems. However, it found that the system consistently misidentified persons.

For each situation below, indicate which type of feasibility is NOT met.

organizational feasibility is not met

A company implemented a new tool for employees to search for information on its Intranet. However, nobody used the new system because the existing tool was preferred.

For each situation below, indicate which type of feasibility is NOT met.

schedule feasibility is not met

A technology consulting firm promised to deliver a new billing system within 12 months but due to unexpected complexities, the system was completed in 15 months.

For each situation below, indicate which type of feasibility is NOT met.

economic feasibility is not met

Over a five year period, a new supply chain management system is expected to increase sales by $20K per year and reduce inventory costs by $30K per year. The upfront cost of the system is $500K and the annual operating cost is expected to be $10K.

For each situation below, indicate which type of feasibility is NOT met.

parallel conversion

A university implemented a new learning management system (LMS) but also ran its old LMS during the first year of implementation in case faculty experienced problems with the new LMS

pilot conversion

An instructor decided to use a new version of a learning management system in only one of her courses before using it in other courses.

phased conversion

A company first implemented the forecasting module of a new supply chain management system and later implemented the inventory management module.

direct cutover conversion

A company stopped using and maintaining its old security management software as soon as it deployed its new security management software.

system requirement

An ERP system must have help documentation that is easily accessible from within the system and which is relevant to the task the user is trying to perform. This is an example of a _____________.
