  Requirement Engineering Process
  - It is a four step process, which includes –
  
  Feasibility study
  - When the client approaches the organization for getting the desired product developed, it comes up with rough idea about what all functions the software must perform and which all features are expected from the software.
  - Referencing to this information, the analysts does a detailed study about whether the desired system and its functionality are feasible to develop.
  - This feasibility study is focused towards goal of the organization.
  - This study analyzes whether the software product can be practically materialized in terms of implementation, contribution of project to organization, cost constraints and as per values and objectives of the organization.
  - It explores technical aspects of the project and product such as usability, maintainability, productivity and integration ability.
  - The output of this phase should be a feasibility study report that should contain adequate comments and recommendations for management about whether or not the project should be undertaken.
  
  Requirement Gathering
  - If the feasibility report is positive towards undertaking the project, next phase starts with gathering requirements from the user.
  - Analysts and engineers communicate with the client and end-users to know their ideas on what the software should provide and which features they want the software to include.
  
  Software Requirement Specification
  - SRS is a document created by system analyst after the requirements are collected from various stakeholders.
  - SRS defines how the intended software will interact with hardware, external interfaces, speed of operation, response time of system, portability of software across various platforms, maintainability, speed of recovery after crashing, Security, Quality, Limitations etc.
  - The requirements received from client are written in natural language.
  - It is the responsibility of system analyst to document the requirements in technical language so that they can be comprehended and useful by the software development team.
  
  Software Requirement Validation
  - After requirement specifications are developed, the requirements mentioned in this document are validated.
  - User might ask for illegal, impractical solution or experts may interpret the requirements incorrectly.
  - This results in huge increase in cost if not nipped in the bud.
