Survey Results Released

Project Forecast has released the results from our Good Scheduling Practices 2015 survey.

The survey sought the views on what are good practices when creating new time schedules (also known as plans and programmes) using predominately the Critical Path Method (CPM).

The survey results can be found here.

This survey has found:

  • Half of the survey respondents start preparing schedules by creating the WBS structure, and the other half start with identification of critical milestones.
  • Two-thirds of respondents indicated they would like to have a scope statement and understanding of project objectives and purpose prior to starting to prepare a schedule.
  • Not all respondents include a start milestone, although all respondents include a finish milestone.
  • A majority of respondents rarely, if at all, use Start-to-Finish (SF) activity relationships.
  • More than half of respondents seek a third party or peer review of the schedule, compare or benchmark the schedule against other similar project schedules.
  • When preparing schedules, a lack of or poorly designed work breakdown structures (WBS) and review of the scope of work is one of the top things planners and schedulers get wrong, closely followed by poor sequencing.
  • When statusing or updating schedules, only two thirds of respondents indicated they checked that all activities in progress show some percentage (%) complete.
  • More than two thirds of respondents indicated that the percentage complete should rarely be based on cost complete, and it should, mostly, be based on the quantity of material installed.
  • More than two thirds of respondents indicated that for activities in progress the completion date should mostly or always be based on the performance (productivity) of the activity, and only sometimes be based on experience.
  • When updating or statusing a schedule, relying on activity owners progress updates, and not validating the progress with measurable objective facts is one of the top things that planners and schedulers get wrong, closely followed by not updating the forecast to reflect reality.
  • All respondents indicated that the completion date should only sometimes, if not then rarely, be based on their experience.

It is recommended:

  • The findings of this survey are used to prepare a good scheduling practices checklist; and
  • The survey is release again in the near to solicit a greater response and to identify any change trends in good scheduling practices.
