Lesson Content/Board Summary
FILING
Meaning of Filing
Filing is the systematic arrangement and keeping of documents, records, or information in an orderly manner for easy storage and quick retrieval when needed. It ensures that documents are protected, easily accessible, and well-organized.
Methods of Filing
There are different methods of filing documents in an office, each with its own structure and benefits:
-
Centralized Filing:
This is a filing system where all records and documents for the entire organization are kept in one central location, usually managed by a specialized filing department or dedicated staff. Files are generally kept in a common filing room.
Advantages of Centralized Filing:
- Uniformity in filing procedures and standards across the organization.
- Better utilization of space and equipment as resources are pooled.
- Reduced cost due to less duplication of equipment and personnel.
- Improved security and control over documents as access is restricted to authorized staff.
- Specialized staff can be trained to handle filing efficiently.
Disadvantages of Centralized Filing:
- Delays in retrieving documents, especially if the central unit is far from the user department.
- Inconvenience to departments that need frequent access to files.
- Risk of complete loss or disruption if the central filing system fails or is damaged.
- Heavy workload on the central filing staff, which can lead to errors during peak periods.
-
Decentralized Filing:
This is a filing system where each department or unit within an organization maintains its own set of files and records relevant to its specific operations. Files are kept within the individual departments.
Advantages of Decentralized Filing:
- Quick and easy access to documents for departmental staff.
- Departmental staff are familiar with their own files, leading to faster retrieval.
- Greater confidentiality for sensitive departmental documents.
- Reduces the workload on a single central filing department.
Disadvantages of Decentralized Filing:
- Lack of uniformity in filing methods and standards across departments.
- Higher overall cost due to duplication of equipment, space, and personnel in each department.
- Risk of misfiling or loss of documents if staff are not properly trained.
- Difficulty in locating documents that might be relevant to multiple departments.
- Potential for inconsistent record-keeping practices.
