AI project estimation: end the pattern of triple time overruns
“It took twice as long” is the norm, not the exception. Studies show that 70 % of IT and implementation projects exceed their original time plan. The reason: estimates are made optimistically, without accounting for history and actual team availability.
Why manual estimates fail
- Optimism bias: we estimate the best-case scenario, not the realistic one
- Forgotten risks: we don’t factor in typical “waiting periods” (approvals, testing)
- Team capacity: we ignore that people are engaged on other projects
- Ignoring history: every project is “different,” even when it isn’t
How AI estimates projects
Input: project template
When creating a new project you enter:
- Project type (software implementation, construction, product development…)
- Scope (large / medium / small)
- Team and availability
AI analyzes history
The system reviews all past projects of a similar type and identifies:
- Average delivery duration
- Typical “slow” phases (where delays always occur)
- Most common risks and their schedule impact
- Speed of specific team members
Output: realistic schedule
AI generates a schedule with:
- Pessimistic and optimistic scenarios
- Probability of on-time delivery (e.g. “72 % chance to finish by June 15”)
- Identified risks with probability and impact
- Recommended buffer for each phase
Project: ERP Implementation for Client XY
Estimated duration: 12 weeks (AI: realistic 14–16 weeks)
⚠️ Risk phases:
• Data migration (2 weeks) — historically 40 % longer
• Customer acceptance testing — always add 1-week buffer
• Pohoda integration — depends on customer IT availability
Recommended commitment to customer: 17 weeks
(at 85 % probability of on-time delivery)
Ongoing tracking vs. plan
During the project AI monitors:
- Actual progress vs. plan (burndown)
- Where the team is falling behind and by how much
- Updated predicted completion date
- Alert when the project deviates more than 20 % from plan
The manager receives a weekly report: “Project is 1.5 weeks behind schedule. Probability of delivery on original date: 35 %. We recommend escalating or adjusting scope.”
