There is a tendency to think of a schedule update as simply moving the data date, but in reality it is far more involved. The updated programme is influenced by the critical path, logic, constraints and remaining duration as much as by actual progress. Below are some of the most frequent errors made in this process.
Myth 1: To Update the Schedule Is to Change the Dates
The truth is an update does much more. It is about recording what has been achieved, making adjustments to the work left to do and letting the schedule's own logic do the recalculating.
Myth 2: The Baseline Is for Reference Only
In fact, the baseline is the approved plan against which one must measure schedule variance, forecast dates and how things are actually progressing.
Myth 3: The Schedule Has to Conform to the Original Plan
An updated schedule ought to be a true reflection of where the project stands. One should record any alterations in sequence or dates rather than trying to force the work to fit the original plan.
Myth 4: Planners Are the Ones Who Have to Supply the Information
Planners cannot do their job without accurate input from the site and commercial teams, engineers and project managers to put the right figures on paper for both completed and outstanding work.
Myth 5: The Point of an Update Is Just to Track Progress
It also serves to highlight any shifts in the critical path, float, schedule performance and forecast dates.
Myth 6: If You Are Behind, Re-Baseline
A delay calls for an analysis of the approved baseline first. Re-baselining alters the benchmark for future performance and is something that should be done only in accordance with the project's change-control procedures.
Myth 7: Float Is Not Important
Float indicates how much time is at hand before an activity puts a key date at risk. Even if the completion date is unchanged, a drop in float is a sign of mounting pressure on the schedule.
Myth 8: You Will Never See the Critical Path Change
Once an update is run and there are changes in relationships, constraints or the work remaining, the critical path may well be different.
Myth 9: A Schedule Is Better for Having More Activities
Detail alone does not make for a good programme. What is needed is a level of detail, appropriate durations, and relationships so that the schedule can be properly maintained and progress measured.
Myth 10: AI Will Solve Your Schedule Issues
While artificial intelligence is useful for analyzing the data, it is no substitute for a planner's review, sound logic, and precise progress reporting.
Summary
A dependable update is not a matter of changing dates. After each one, the programme should be reviewed for its logic, constraints, float, and critical path to ensure it is an accurate representation of events and a sound basis for forecasts.
