Rules of Credit

Lesson Objective

  • Introduction to concept of rules of credit 
  • Various norms to assess progress
  • Benefits of pre-defined rules of credit 
Effort required – 15 minutes 

Lesson Introduction

Rules of credit are used to measure the progress of work completed against the planned work. The most commonly used rules of credit are;

  • 0/100 – Work is considered as earned (completed) when it is 100% completed.
  • 50/50 – 50% of the work is considered as earned as soon as the work starts. The remaining 50% will be considered as earned only when the remaining 50% is fully completed.
  • 25/75 – 25% of the work is considered as earned as soon as the work starts. The remaining 75% is considered as completed only when 100% of the work is completed.
  • 20/80 – 20% of the work is considered as earned as soon as the work starts. The remaining 80% is considered as completed only when 100% of the work is completed.
  • When none is defined, we apply % completed based on actual measurement or expert judgment.
