In an information systems team, which role primarily writes computer programs to implement the jobs and specifications provided by users or analysts?

Introduction / Context:
Software development is a collaborative process involving several roles. Understanding who does what helps clarify handoffs and expectations. A common confusion exists between a system analyst, who defines requirements and designs solutions, and a programmer, who writes code to realize those designs. This question targets that distinction within an MIS or software project context.

Given Data / Assumptions:

• User needs are gathered and translated into specifications.
• Code must be produced to execute those specifications on computers.
• Distinct operational roles also exist (operators and data entry staff).

Concept / Approach:
A programmer converts logic and specifications into source code, using programming languages, libraries, and frameworks. A system analyst focuses on requirements elicitation, process modeling, and high-level design. A computer operator monitors and runs jobs in production environments. A data entry operator inputs data but does not develop software. Therefore, the primary code author is the programmer, even though in small teams one person may wear multiple hats.

Step-by-Step Solution:

Verification / Alternative check:
Standard SDLC descriptions and job profiles define programmers/software engineers as the role that produces executable code from design artifacts and requirements.

Why Other Options Are Wrong:

• Data entry operator: focuses on data capture, not coding.
• System analyst: defines and designs; may prototype but is not primarily tasked with full implementation.
• Computer operator: runs and monitors systems, not development.
• None: incorrect because “Programmer” is correct.

Common Pitfalls:
Assuming analysts always code; in many organizations, coding is handled by programmers or software engineers.

Final Answer:
Programmer
