Case for action
A part of the preliminary investigation report to management that summarizes project requests and makes specific recommendations.
computer resources committee

Constraint
A requirement or a condition that the system must satisfy or an outcome that the system must achieve.
critical success factor
Vital objective that must be achieved for the enterprise to fulfill its mission.
Customer relationship management (CRM)
Many companies implement systems to integrate all customer-related events and transactions including marketing, sales, and customer service activities.
Discretionary project
Where management has a choice in implementing a project, they are called discretionary. For example, creating a new report for a user is an example of a discretionary project.

Achieved if the projected benefits of the proposed system outweigh the estimated costs involved in acquiring, installing and operating it.
Electronic product code (EPC)
Technology that uses RFID tags to identify and monitor the movement of each individual product, from the factory floor to the retail checkout counter.
Electronic proof of delivery (EPOD)
A supplier uses RFID tags on each crate, case, or shipping unit to create a digital shipping list to verify receipt of goods.
Encryption
A process where data is coded (converted into unreadable characters) so that only those with the required authorization can access the data.
Fishbone diagram
An analysis tool that represents the possible causes of a problem as a graphical outline. Also called an Ishikawa diagram.
Intangible benefit
Positive outcome that is difficult to measure in dollars. However, intangible benefits can be very important in the calculation of economic feasibility. An example of an intangible benefit might be a new website that improves a company’s image.
