Per your textbook, the most important factor in choosing a development strategy is to satisfy users.
False
Our remaining activities in the Analysis phase include
Evaluate alternative solutions (what are some of the "alternatives"?)
Prepare the "Systems Requirements" document (our "deliverable" for this phase)
________?
Presentation to management.
Software development options include:
develop in house
outsource development
combination (in house plus outsource)
_______________?
Purchase (and possibly customize)
Per your textbook, once completed (the Analysis tasks) - we will present to Management.
Management will decide:
Develop in-house (the next step is systems design)
Modify an existing system (not always an option) (the next step is systems design)
Purchase a software package (customize if necessary and possible) (the next step might be systems implementation, systems design, or planning for testing and documentation of modifications made by the vendor)
Perform ADDITIONAL ANALYSIS (no decision made yet) (the next step is to do further systems analysis work) OR
_________________?
Stop all further work
Reasons for "in house" development include:
1. Satisfy a unique business requirement
2. Satisfy unique security requirements
3. ____________?
Meet constraints of existing systems
Per your textbook, the most important factor in choosing a development strategy is TCO.
True
Reasons for purchasing software include:
1. Requires less time to implement
2. Lower costs
3. Obtain input from other companies
4. __________?
Requires less technical development staff
The _______, also called a software requirements specification is the deliverable for the Analysis Phase, and
Contains the requirements for the new system
Describes the alternatives that were considered
and makes a specific recommendation to management
Systems Requirements Document
The system requirements document should provide cost and time estimates for future development work
True
If "software purchase" is being considered, a(n) _____________ is developed and made available to prospective vendors to allow them to submit the requested information concerning their software.
RFP (request for proposal)
In the Systems Design Phase, you will work on a logical design that will meet the specifications described in the system requirements document.FalseWithin the Design Phase, tasks will include user interface design, system architecture, and _________data designAs presented in the chapter, which of the following answers is NOT a potential "component" of a Report?Business CaseThe goal of systems design is to build a system that is effective, reliable, and _________maintainablePrinted reports, include detail, exception, and _____ reports.summaryThe purpose of systems design is to create a physical model of the system that satisfies the design requirements that were defined during the systems analysis phaseTrueWhich of the answers provided is NOT a "data validation" rule?acquisitionTo "Create an Interface That Is Easy to Learn and Use" you should: 1. Focus on system design objectives 2. Create a design that is easy to understand and remember 3. Provide commands, actions, and system responses that are consistent and predictable 4. Clearly label all controls, buttons, and icons 5. Select familiar images that users can understand, and provide on-screen instructions that are logical, concise, and clear. 6.
