INCOSE ASEP Chapter 4 Flashcards
Define - Technical processes
Used to define the requirements for the system, to transform the requirements into an effective product, to permit consistent reproduction of the product where necessary, to use the product to provide the required services, to sustain the provision of those services and to dispose of the product when it is retired from service.
Need vs Requirement
Need - Something that is wanted or required for the system.
Requirement - Formal structured statements that can be verified and validated. There may be more than one requirement defined for each need.
What are the 14 technical processes?
- Business/mission analysis
- Stakeholder needs & requirements definition
- System requirements definition
- Architecture definition
- Design definition
- System analysis
- Implementation
- Integration
- Verification
- Transition
- Validation
- Operation
- Maintenance
- Disposal
Define: Business Requirements Specification (BRS)
Where are business requirements often captured. At an executive level (do not get too specific).
Define: Stakeholder Requirements Specification (StRS)
Where the formal set of stakeholder requirements (developed from the stakeholder needs) are captured. Should be traceable to stakeholder needs and the BRS.
Define: Business/Mission Analysis Process
To define the business or mission problem or opportunity, characterize the solution space, and determine potential solution class(es) that could address a problem or take advantage of an opportunity.
Define: ConOps
Concept of Operation: Addresses the leadership’s intended way of operating the organization. Prepared at the leadership/enterprise level
Define: OpsCon
Operational Concept: Describes what the system will do (not how it will do it) and why. Prepared at the business level.
Define: System Requirements Specification (SyRS)
A baseline set of complete, accurate, non ambiguous system requirements, recorded in the requirements database and accessible to all parties.
What is the purpose of the Stakeholder Needs & Requirements Definition?
To define the stakeholder requirements for a system that can provide the capabilities needed by users and other stakeholders in a defined environment.
What are the drivers for the majority of the system life cycle processes?
Requirements (business, stakeholder, and system)
What is the purpose of the Systems Requirements Definition process?
To transform the stakeholder, user-oriented view of desired capabilities into a technical view of a solution that meets the operational needs of the user.
What are the foundation of the system definition and form the basis for the architecture, design, integration, and verification?
System requirements
Is requirements definition iterative or recursive?
Both. Iteration is expected as more information is available. Recursion is applied to define requirements for each system element.
What are the implementation measures of sucess?
Measures of Performance (MOPs) and technical performance measures (TPMs)
What are the operational perspective measures of success?
Measures of Effectiveness (MOEs) and Measures of Suitability (MOSs)
What are the four standard methods of verification?
Inspection, analysis, demonstration, or test. Only a single method should be used.
What is the purpose of the Architecture Definition Process?
To generate system architecture alternatives, to select one or more alternative(s) that frame stakeholder concerns and meet system requirements, and to express this in a set of consistent views.
