What's the difference between logo design CI and CIS?

CI, also known as CIS, is the abbreviation of English CorporateIdentitySystem, which is generally translated as "enterprise visual identity system" at present. CI design means the design of corporate identity, including the design of corporate name, logo, standard font, color, symbol pattern, slogan and mascot. The so-called CIS "corporate identity" is the sum of the attitudes and effects of multi-layer stakeholders around the enterprise through visual elements such as trademarks. The so-called "stakeholders" include consumers, shareholders, investors, employees, financial institutions, affiliated enterprises, journalists, governments and public organizations. It is worth noting that people with different knowledge levels often have different impressions of the same enterprise, and all stakeholders may have a very outrageous impression because they don't understand the enterprise. How to correct the divergent or arrogant impression of stakeholders on the enterprise is the purpose of company information transmission. CIS includes three parts, namely MI (Mind Recognition), BI (Behavior Recognition) and VI (Visual Recognition). Some scholars believe that CIS is composed of the above three parts. EI is the abbreviation of English EnrironmentalIdentity, which is environmental recognition.
