steps in - Requirement Elicitation 1. Collaborative Requirements Gathering 2. Quality Function Deployment 3. User Scenarios 4. Elicitation Work Product
1. Collaborative Requirements Gathering joint team of customers & developers work together - - - - requirements. to identify the problem, to suggest the solution, to negotiate different approaches & to specify preliminary set of solution
2. Quality Function Deployment the customer needs & wants - Are translated into - technical requirements for software The main focus is on - Customer satisfaction
QFD includes Three Types of Requirements Normal Requirements (explicit) - clearly stated by the customer, during the meeting with the customer. Expected Requirements (implicit) - requirements, which, system must be having, - even if customer didn t mention about them. - - - if these requirement are not present, then, the system will be meaningless. ex. New slide insert in PowerPoint Exciting Requirements - when certain requirements are satisfied by the software - beyond customer s expectations - ex spell check facility in word processor
Various Types of Deployments Conducted During Software Development Process Are - Function deployment - different functionalities of the software - are deployed Information deployment - information related to these functionalities, - is deployed. Task deployment - the task associated with each function must be identified. Value analysis - identify the priorities of requirements
3. Usage Scenarios During RE, - - overall version for systems functions & features get developed. To understand how these functions & features are used by different classes of end users, - - developers & users, create a set of scenarios This set identifies - the usefulness of the system to be constructed. This set is normally called as use cases.
4. Elicitation Work Product Following work products get produced, during requirement elicitation - - - - - A statement of feasibility study A List of various stakeholders A technical description of system environment A list of requirements & constraints Ex. Aadhar card. Set of usage scenarios, along with operating conditions - - The prototype, that may get developed for defining requirements in better manner. - - - These work products are then reviewed by all the people who participate in the requirements elicitation.
