Baseline Start VS Start in Microsoft project


 In Microsoft Project, the Baseline Start and Start fields have different purposes and meanings:

1. Start Date (Start Field)

  • Definition: The Start field shows the scheduled start date of a task based on the current project plan.
  • Changes? Yes, it can change if the task is delayed, rescheduled, or dependencies shift.
  • When is it used? It is used for tracking the current plan and adjusting schedules as needed.

2. Baseline Start Date (Baseline Start Field)

  • Definition: The Baseline Start field shows the start date of a task at the time the baseline was set.
  • Changes? No, it does not change unless you manually update the baseline.
  • When is it used? It is used for comparing the original plan (baseline) with the actual or current schedule.

Key Differences:

FeatureStartBaseline Start
What it showsCurrent scheduled start dateOriginal planned start date when the baseline was set
Can it change?Yes, if the schedule updatesNo, unless you reset the baseline
PurposeShows real-time schedulingTracks project performance vs. the original plan

Example:

  1. You schedule a task to start on March 1 and save a baseline.
    • Baseline Start = March 1
    • Start = March 1
  2. Later, due to delays, the task is rescheduled to March 5.
    • Baseline Start = March 1 (remains the same)
    • Start = March 5 (updates to reflect the delay)

🔹 Why is this important?
Comparing Baseline Start with Start helps track project delays, measure performance, and report changes effectively.
