MA – Nov 2017 – L2 – Q2a – Introduction to management accounting

Identify and explain five features of a good coding system for efficient and effective information management, whether manual or computerized.

a) An efficient and effective coding system, whether manual or computerized should incorporate certain features.

Required: Identify and explain FIVE features of a good coding system.

(5 marks)

The requirements for an efficient coding system:

  • Every number used in the code should be unique and certain, i.e. it should be easily identified from the structure of the code.
  • Elasticity and comprehensiveness is an absolute must for a well-designed coding system. It should be possible to identify a code for every item and the coding system should be capable of expanding to accommodate new items.
  • The code should be brief, meaningful and significant.
  • The maintenance of the coding system should be centrally controlled. It should not be possible for individuals to independently add new codes to the existing coding system.
  • Codification systems should be of the same length. This makes errors easier to spot and it assists computerized data processing.
  • The coding system must allow for expansion.
  • The likelihood of errors going undetected should be minimized.
  • If the code consists of alphabetic characters, it should be derived from the item’s description or name (ie mnemonics should be used).
  • There should be readily available index or reference book of codes.
  • Existing codes should be reviewed regularly and out-of-date codes removed.
