Answers| Latest Update 2024/2025
What are the steps of the design phase?
1. Determine preferred system acquisition strategy (make, buy, or outsource)
2. Design the architecture for the system
3. Make hardware and software selections
4. Design system navigation, inputs, and outputs
5. Convert logical process model to physical process model
6. Update CASE repository with additional system details
7. Design the programs that will perform the system processes
8. Convert logical data model to physical data model
9. Update CASE repository with additional system details
10. Revise CRUD matrix
11. Design the way in which data will be stored
12. Compile final system specification
What is the final deliverable of the design phase?
System specification
What are the three acquisition strategies?
1. Develop a custom application in-house
2. Buy a packaged system and (possibly) customize it
3. Rely on an external vendor, developer, or service provider to build or provide the
system (outsourcing)
,Under what circumstances would you choose each one of the three acquisition
strategies?
1. Custom development:
used when the business need is unique; in-house functional and technical experience
exists; there is a desire to build in-house skills; the project has a highly skilled project
manager and the time frame is flexible.
2. Buy a packaged system and (possibly) customize it: used when there is a common
business need; in-house functional experience exists; the skills are not strategic; the
project has a project manager who can coordinate vendor's efforts; and when the time
frame is short.
3. Outsourcing: used when the business need is not core to the business; in-house
functional or technical experience does not exist; the decision to outsource is a strategic
decision; the project has a highly skilled project manager; the time frame is short or
flexible; want to hire experts.
What is an Request for Proposal (RFP) and its purpose?
A document that solicits a formal proposal from a potential vendor, developer, or
service provider
RFPs describe in detail the system or service that is needed, and vendors respond by
describing in detail how they could supply those needs.
What is a Request for Information (RFI) and its purpose?
A shorter, less detailed request that is sent to potential vendors to obtain general
information about their products and services.
, RFIs may be sufficient for smaller projects with smaller budgets.
Sometimes, the RFI is used to determine which vendors have the capability to perform a
service.
It is often then followed up with an RFP to the qualified vendors.
What is an Request for Quote (RFQ) and its purpose?
Used when a list of equipment is so complete that the vendor need only provide a price,
without any analysis or description of what is needed
For an Alternative matrix, what is listed across the top row?
- Evaluation Criteria
- Relative Importance
- Alternatives
- Score
- Weighted Score
For an Alternative matrix, what is listed down the first column?
- Technical issues
- Economic issues
- Organizational issues
- Total
How is the right alternative selected in a matrix? (hint: the one with the highest
weighted score)
The highest weighted score achieves the best match alternative.
