Software development principles

  • Show error details to end-user to optimize troubleshooting, if it does not create security vulnerabilities
    • If end-user can not solve the issue, send the error details to software developer. Avoid sending too many error reports
  • Consider performance (number of records, files)
  • Use correct english language within the code
  • Minimize size of code (e.g. use shared procedures when similar code is used in many places)
  • Improve efficiency of the coding every day
