What is informal system?
Ad hoc, informal work groups can develop informal systems to fulfil information needs that formal systems are unable to address.

Informal systems for gathering, processing, storing, or disseminating data do not adhere to any formal or pre-established rules.
Why should systems analysts be aware of informal systems?
If a system analyst is well-versed in the formal and informal structures of an organisation , they can quickly identify candidates for system analysis phase interviews. The establishment of formal systems requires a lot of time and work, and people are frequently resistant to change, which leads to the emergence of informal systems. There are instances where a system is required but there isn't enough time to wait for one to be formally built. To handle the problem, an informal system is formed (perhaps including components of the previous system). Until a formal system can be constructed, the informal system is frequently intended to be used in the interim. However, because it is a functioning system and there are demands for the time and money needed to construct or maintain other formal systems, the temporary system frequently becomes the established system. Additionally, unofficial mechanisms develop to deal with unique situations that cannot be resolved by modern technologies.
