Question

BlackTom AI · Accepted Answer

Internal factors are those originating within an organization that motivate a formal system request — typically users who work with the system and the current system’s shortcomings.

1. Relevant knowledge points and concepts
- Internal factors: drivers coming from inside the organization (employees, internal processes, existing systems).  
- External factors: drivers coming from outside (customers, market demands, new external technologies or regulations).  
- Typical internal causes of system requests include user requests for better functionality, and problems or limitations in the existing system that require change.

2. Step-by-step reasoning
- Examine each listed item to decide whether it is internal or external.
  i. User request — Users are internal stakeholders (employees or internal users interacting with the operational system). Their requests to improve efficiency, reliability, or maintainability come from inside the organization, so this is an internal factor.
  ii. Customer — Customers are external stakeholders; their demands come from outside the organization, so this is an external factor.
  iii. Existing system — Problems or limitations in the current system (performance, maintainability, reliability) are internal issues that prompt change requests, so this is internal.
  iv. Technology — Technology changes are typically external drivers (market or vendor innovations) that push organizations to adapt; therefore generally classified as external.

3. Calculations/intermediate steps
- Not applicable (no numeric calculations required). The “intermediate steps” are the classification judgments above (internal vs external) for each item.

4. Why the correct answer is correct
- Both i (User request) and iii (Existing system) clearly originate inside the organization and therefore are internal causes of a system request to change an operational system to be more efficient, reliable, and maintainable.

5. Why other options are incorrect
- Options including ii (Customer) are incorrect because customers are external stakeholders.  
- Options that include iv (Technology) are incorrect here because technology change is considered an external driver in this classification. Any choice that includes ii or iv therefore does not match the internal-only requirement.

6. Conclusion
- The internal factors are i and iii; therefore the correct answer is A. (Confirms provided answer: A. i and iii.)
