11) The systems design would include a feasibility study to determine whether that solution was feasible or achievable from a financial, technical, and organizational standpoint.
12) Systems design is the analysis of the problem that the organization will try to solve with an information system.
13) The information requirements of a new system involve identifying who needs what information, where, when, and how. Requirements analysis carefully defines the objectives of the new or modified system and develops a detailed description of the functions that the new system must perform.
14) Unit testing,
or program testing, consists of testing each program separately in the system.
15) System testing tests the functioning of the information system as a whole.
16) Acceptance testing provides the final certification that the system is ready to be used in a production setting.
17) Conversion is the process of changing from the old system to the new system.
18) In a parallel strategy, both the old system and its potential replacement are run together for a time until everyone is assured that the new one functions correctly.
19) The direct cutover strategy replaces the old system entirely with the new system on an appointed day.
20) The pilot study strategy introduces the new system to only a limited area of the organization, such as a single department or operating unit.
