It only affects the business's marketing approach, not financial or operational decisions.
All small businesses have the same definition worldwide, so it doesn't impact growth strategies.
It influences eligibility for government support, which can encourage or limit expansion.

Why is software testing integrated throughout the development process rather than only performed at the end?
Because early testing helps identify and fix defects sooner, reducing costs and improving quality.
Because testing at the end is too expensive and unnecessary if coding is done correctly.
Because testing is only about finding bugs after the software is fully built.

Corrosion Protection
Sacrificial Anode
Metal components that self-sacrifice to prevent rust reveal nature's electrochemical battles
8 days ago
0
Why do sacrificial anodes corrode instead of the metal structures they protect?
Because they are coated with a protective layer that prevents corrosion on the main metal.
Because they are made of more reactive metals that lose electrons more readily, protecting the main metal by corroding first.
Because they electrically insulate the metal structure from the environment, stopping corrosion altogether.
