State relationship of Static testing w.r.t SDLC and verification?

 We know that SDLC comprises of different stages as below:

Requirement Analysis → Feasibility Study → Design → Coding → Testing → Installation → Maintenance. Phases till Coding stage are known as verification phases.

Every testing that we do in verification phases of SDLC starting from requirement analysis phase to Coding phase is known as Static testing. There are various techniques used to perform static testing as walkthroughs, reviews and inspections. Static testing helps in early identification of issues or loopholes before the software is developed. Using different techniques of static testing (walkthroughs, reviews and inspections) different documents associated with software development is investigated as source code, functional specification documents, design documents, database model etc.
