Requirement Detail vs Development Time
Lock safety, regulatory, and interface requirements first; allow implementation-level specifications to mature progressively without blocking design progress.

Regulations
Business Context
Detailed requirements improve engineering clarity and reduce interpretation, but developing exhaustive specifications before design begins can significantly extend front-end schedules and consume effort on details that may later change.
Green Field Industrial Projects TRIZ Resolution
Define requirements progressively according to when they become necessary. Establish performance, safety, regulatory, and interface requirements early while allowing lower-level implementation requirements to develop with the design.
Applicable TRIZ Principles
Principle 1 – Segmentation organizes requirements according to level and timing.
Principle 10 – Prior Action defines requirements that drive architecture before dependent decisions.
Principle 15 – Dynamics allows detailed requirements to mature with project information.
Expected Outcome
Shorter development cycles
Better requirement quality
Reduced unnecessary specification
Improved engineering clarity
Decision Indicators
Engineering waits for exhaustive specifications before beginning.
Detailed requirements are repeatedly rewritten.
Critical requirements remain hidden among low-value detail.
Suppliers receive specifications containing unnecessary restrictions.
Teams define implementation methods before functional needs are established.
