Prioritising requirements helps project teams focus on the most critical functionality first and efficiently manage changes. It also contributes to a good SRS by categorising requirements by importance and stability.
For complete preparation, combine this set with full subject-wise practice for Software Engineering. You can also explore other subjects and sets from the links below.
A typical SRS template includes: Introduction (purpose, scope, definitions) so everyone understands context; Overall Description (product perspective, user needs, constraints) to set background; Functional Requirements (detailed behaviours) describing what the system does; Interface Requirements (user, hardware, software) because interfacing matters; Non-functional Requirements (performance, reliability, security) for quality; Design Constraints and Assumptions to account for limitations; Appendices, Glossary for clarity. This structure ensures clarity, completeness and traceability and supports development, testing and maintenance.
ISO/IEC standards (for example ISO/IEC 9126/25010) define characteristics like functionality, reliability, usability, efficiency, maintainability, portability etc., but ‘fast-tracking’ is not a quality characteristic in that model.
Non-functional requirements describe the quality attributes and constraints of the system (for example performance, usability, security, reliability) rather than what the system must do (which is covered by functional requirements). Understanding both types is essential in interview discussions on requirements engineering.
A good SRS should avoid implementation details so that it remains design-independent. Characteristics such as completeness, unambiguity, verifiability, modifiability, traceability and consistency are recommended.
Use-case workshops, interviews, surveys and prototyping are typical techniques used in requirements elicitation. They help capture what stakeholders expect from the system and drive the SRS documentation.
Traceability allows you to track requirements from their origins (stakeholder, business need) through design, implementation and test cases. This ensures that all requirements are addressed and is a key quality trait of an SRS.
‘User-friendly’ is subjective and open to interpretation, making the requirement ambiguous. A good SRS avoids such vague language and specifies measurable criteria instead.
Business requirements capture high-level stakeholder goals and business value; system requirements break them down into functional and non-functional system behaviours. Recognising this distinction shows maturity in requirements-engineering knowledge.
When writing good requirements you should: use clear and unambiguous language (avoid vague words); ensure each requirement is testable and measurable; maintain consistency with terminology and format; include traceability links; assign identifiers and priority; modularise requirements so that changes affect minimal parts; review and validate with stakeholders. /n/n These practices reduce risk by preventing misunderstandings, reducing rework, enabling better planning/estimation, and facilitating effective testing and change-control. A strong SRS is a foundation for project success.
Requirements elicitation is the process of discovering and gathering stakeholder needs, using interviews, workshops, observation, prototyping etc. Specification is the subsequent process of documenting those requirements into a coherent SRS document. /n/n Both are critical: without elicitation you may miss real user needs or misunderstand them; without specification you lack a stable, verifiable contract and baseline for design/testing. Skipping or doing either poorly leads to scope creep, rework and quality issues in later phases.
