Review of existing records, procedures, and forms helps to seek insight into a system which describes the current system capabilities, its operations, or activities.

Advantages

  • It helps users to gain some knowledge about the organisation or operations by themselves before they impose upon others.
  • It helps in documenting current operations within a short span of time as the procedure manuals and forms describe the format and functions of the present system.
  • It can provide a clear understanding about the transactions that are handled in the organisation, identifying input for processing, and evaluating performance.
  • It can help an analyst to understand the system in terms of the operations that must be supported.
  • It describes the problem, its affected parts, and the proposed solution.

Observation

This is a method of gathering information by noticing and observing the people, events, and objects. The analyst visits the organisation to observe the working of the current system and understands the requirements of the system.

Advantages

  • It is a direct method for gleaning information.
  • It is useful in situations where authenticity of data collected is in question or when complexity of certain aspects of a system prevents clear explanation by end-users.
  • It produces more accurate and reliable data.
  • It produces all the aspects of documentation that are incomplete and outdated.
