In software engineering, what do we call a program specifically used to develop, repair, test, or enhance other programs and their artifacts?

Introduction / Context:
Modern development relies on specialized programs that help build, analyze, test, and improve other software. Identifying the umbrella term for such supportive programs is important for understanding toolchains and software life-cycle management.

Given Data / Assumptions:

• We need a term for programs used in development, repair, or enhancement of other programs.
• Examples include debuggers, profilers, version control clients, and build systems.
• We must distinguish from general runtime system components or end-user apps.

Concept / Approach:
Software tools are programs that support software construction and maintenance. While utilities are often small system aids (disk cleanup, compression), the broader and more precise category encompassing IDEs, compilers, linkers, debuggers, static analyzers, and refactoring assistants is software tools. System software (like operating systems or drivers) provides runtime services but is not primarily authored to develop other programs. Applications programs serve end-user needs.

Step-by-Step Solution:
Map the described purpose to category names.Development, repair, enhancement → software engineering support → software tools.Confirm that utilities and system software do not fully capture the scope.Therefore, choose ‘‘Software tool.’’

Verification / Alternative check:
Toolchains and DevOps pipelines are commonly described as collections of software tools (e.g., compiler + linter + test runner + CI). The term is standard in textbooks and professional practice.

Why Other Options Are Wrong:

• System software: Focuses on OS and low-level services rather than building other programs.
• Applications program: End-user focused, not primarily for developing software.
• Utility program: Narrower scope; may be part of tools but not the comprehensive term.
• None of the above: Incorrect because software tool fits precisely.

Common Pitfalls:
Equating utilities with the full development environment. Utilities are a subset; software tools is the accurate umbrella term.

Final Answer:
Software tool
