Documented verification requirements; Allocated Baseline. Requirements and logical entities are allocated to products, product components, people, or associated processes. Once you have defined the architecture at the next level (N+1) AND have allocated N level requirements to those parts of the architecture, each part then will develop (derive) children requirements at their level (N+1) and then link these “children” requirements back to their parent requirement at the previous “N” level. If just a copy and no derived children requirements, then the engineering work needs to be done to derive a necessary and sufficient set of children requirements to satisfy the allocated parent. Derived Technical Requirements are those that result from the analysis and allocation of Technical Requirements to logical functional architectures that are developed as part of the Requirements Analysis process; or from the Analysis of Alternative (AoA) solutions done later as part of the Architecture Design Process. Some subsystem requirements will be realized in a single discipline, so those are easy. Writing a Requirements Document “For Multimedia and Software Projects” by Rachel S. Smith, Requirements Development, Verification, and Validation Famous Failures by Bahill & Henderson. Demonstrate requirement validity through analysis, authority or other demonstration of need. Demonstrate requirement validity through analysis, authority or other demonstration of need. Derived Technical Requirements Requirements Management 3-30-31, 2004 IntroductionIntroduction Requirements are the single thread that goes through a project from conception through build, test and flight Whole project is constructed so you can meet the requirements Based on the need to measure a physical phenomena high level requirements are envisioned for a system to meet the need.

Derived requirements are lesser than user requirements. The allocated requirements could be:  “The hardware shall be able to measure input temperatures down to -50o C and up to 90oC,” and “The software shall detect when input temperature goes below -40o C or above 80oC.”. Tagged as:   Both approaches are acceptable from a compliance point of view. exida offers services, tools, and training to help organizations meet regulatory requirements, achieve safe operations, and deliver results.

Example Derived Requirement: Allocated Baseline: Describes the functional and interface characteristics for all system elements (allocated and derived from the higher-level product structure hierarchy) and the verification required to demonstrate … Derived Requirement are requirements that are not explicitly stated in the set of Stakeholder requirements yet is required to satisfy one or more of them. requirements, safety-related requirements and system architecture [10]. Derived Technical Requirements are those that result from the analysis and allocation of Technical Requirements to logical functional architectures that are developed as part of the Requirements Analysis process; or from the Analysis of Alternative (AoA) solutions done later as part of the Architecture Design Process. In my next entry, I will discuss validation test planning and how requirements can be verified using the validation test plan.

Derived Technical Requirements become the basis for the solution-specified requirements for the system model and is a ‘design-to’ requirement for the system. Control Change This might be derived further into (at least) two child requirements: “The device shall be able to measure input temperatures down to -50o C and up to 90oC,”, and “The device shall detect when input temperature goes below -40o C or above 80oC.” Allocation of a requirement simply assigns the requirement to a specific context.   IEC 61508   SW-LLRs are software requirements that were developed from SW-HLRs or are derived, which describe in sufficient detail to allow source code to be implemented without additional information [10].
