Acquiring Information Systems: Reasons for External Acquisition
oPossible Scenarios
oLimited IS staff
oIS Staff has limited skill set
oIS Staff is overworked
oProblems with performance of IS staff
2 Options:
oExternal acquisition of pre packaged system
oOutsourcing systems development
External Acquisitions Steps
oFirst two steps same as SDLC
o3: Development of a Request for Proposal
A summary of existing systems and applications
Requirements for system performance and features
Reliability, backup, and service requirements
The criteria that will be used to evaluate proposals
Timetable and budget constraints (how much you can spend)
o4. Proposal evaluation
Evaluation may include:
Viewing system demonstrations
Evaluating system performance
Judging how system stacks up to important criteria
Use of system benchmarks
Response time given a specified number of users
Time to sort records
Time to retrieve a set of records
Time to produce a given report
Time to read in a set of data
The evaluation of the proposal will involve looking at all the financials, but
will also involve comparing the proposed solution to the requested
features, and noting differences and capabilities.

Document Summary
Acquiring information systems: reasons for external acquisition: possible scenarios, limited is staff o o. Is staff is overworked: problems with performance of is staff. 2 options: external acquisition of pre packaged system, outsourcing systems development. External acquisitions steps: first two steps same as sdlc, 3: development of a request for proposal. A summary of existing systems and applications. The criteria that will be used to evaluate proposals. Timetable and budget constraints (how much you can spend: 4. Judging how system stacks up to important criteria. Response time given a specified number of users. Time to retrieve a set of records. Time to read in a set of data. The evaluation of the proposal will involve looking at all the financials, but will also involve comparing the proposed solution to the requested features, and noting differences and capabilities: 5. Weighted scoring system works well for this.
