Software Engineering is part of Computer Science and holds 1,969 questions with answers, free to read and with no account needed.
Questions from this area appear in PPSC, FPSC, NTS, KPPSC and SPSC papers. Each guide explains how that paper is built and which subjects carry it.
Attempt each question before revealing the answer, and keep a note of the ones you get wrong — those are the topics worth reading about properly. If an answer looks wrong, there is a link to report it on every question.
Answer: C. Application composition model
The application composition model was deployed early on when UI prototyping and technology maturity were critical. Selecting option C correctly identifies the cost estimation model suited for early interface composition....
Answer: C. A reuse model
A reuse model calculates the effort needed to integrate reusable parts or automated code. Software reuse reduces development time by incorporating pre-existing components or generated code. Specialized cost estimation mo...
Answer: A. An application-composition model
The application-composition model presumes systems are built from reusable components, scripts, and database routines. This model evaluates projects that assemble existing software modules rather than writing code from s...
Answer: D. All of the mentioned
Configuration items encompass all work products produced throughout the software development lifecycle. Source code, design documents, test specifications, and logs require formal tracking and control. Every specified it...
Answer: B. Business risks
Business risks threaten the fundamental viability of software being constructed by impacting market relevance. If market conditions shift or customer demand vanishes, the software becomes obsolete before completion. Iden...
Answer: B. Preliminary concept planning
Preliminary concept planning evaluates risks associated with chosen implementation technologies. It assesses whether the proposed project scope is technically feasible. This assessment identifies potential hurdles before...
Answer: B. Adaptation criteria
Adaptation criteria are utilized to establish the recommended level of rigor for applying software processes. Selecting option B correctly identifies the criteria used to tailor process formality to project needs. Not ev...
Answer: A. Risk monitoring
Risk monitoring evaluates risks and mitigation strategies while revising them as understanding deepens. Continuous tracking ensures that evolving project risks are addressed with updated mitigation plans. Risk monitoring...
Answer: A. Personnel Factor
Programming language proficiency is categorized under personnel factors in the COCOMO estimation model. The skill and experience of team members directly influence software productivity and development effort. Personnel...
Answer: A. Agile method
Agile methods prioritize frequent automated system builds to detect integration flaws early. Automated testing runs continuously against these builds to surface software defects rapidly. This iterative feedback loop ensu...
Answer: A. Function-related metrics
Function-related metrics relate directly to the overall functional scope of delivered software systems. Using measures like Function Points evaluates software size based on user interactions and business features. Functi...
Answer: D. An early design model
An early design model estimates effort once requirements are fully stabilized. It applies during the initial system design stages of software projects. This model uses architectural parameters to predict required develop...
Answer: D. All of the mentioned
Problem decomposition, partitioning, and elaboration together form the central core of requirements analysis. Selecting option D correctly encompasses all these vital problem-solving activities. Analysts break large requ...
Answer: A. 40-20-40
The 40-20-40 rule recommends distributing effort across analysis, design, coding, and testing. Allocating 40 percent of effort to testing ensures high software reliability and quality. Heuristics like the 40-20-40 rule g...
Answer: B. Empirical estimation models
Empirical estimation models provide structured mathematical frameworks alongside decomposition strategies. These models use historical project data to predict effort, cost, and schedule requirements. Combining decomposit...
