The Domino Effect of PM Changes in IT Projects: Why Lack of Handover Is the Biggest Risk

Imagine this situation: a PM change in an IT project. Anna takes over the project from Piotr. The documentation is “complete,” tasks are in Jira, statuses in Confluence – everything seems under control.

But after a few days, problems begin: conflicting priorities, decisions require escalation, a key stakeholder refuses to accept changes. The team feels the pressure, and information chaos quickly turns into decision-making chaos.

This is a classic example of the domino effect that occurs in IT projects when there is no handover.

The Domino Effect: From Information Chaos to Decision-Making Chaos

Informal handover in IT creates a vicious cycle:

1. Lack of knowledge → wrong decisions

2. Wrong decisions → escalations

3. Escalations → pressure on the team

4. Pressure → another Project Manager rotation

5. Another rotation → even greater chaos

I have seen this dozens of times in companies that claim “everything is documented in Jira.” Technical documentation and tasks cannot replace contextual knowledge, meaning the subtle decisions, dependencies between tasks, and relationships with stakeholders.

Why Lack of Handover During a PM Transition in an IT Project Is So Dangerous

• Loss of project context – the new PM does not understand why decisions were made or which dependencies are critical.

• Inconsistent priorities – lack of formal knowledge transfer causes conflicts within the team and misunderstanding of stakeholder expectations.

• Chaos in decision-making – every decision requires escalation or additional analysis, which slows down the project.

• Pressure on the team and another PM rotation – lack of stability generates pressure, closing the vicious cycle of chaos.

How to Reduce Risk During a PM turnover in IT

Companies that want to maintain project stability despite Project Manager Transition implement systematic practices:

• Formal handover in IT – documentation, checklist, and meetings transferring the full project context.

• Shadowing / reverse shadowing sessions – the new PM takes over responsibilities under the supervision of the outgoing PM to learn the project’s subtleties.

• GAP Challenge – a quick project assessment on a 0–5 scale allows detection of knowledge gaps and critical risks.

• Risk maps for PM Transition – planning potential threats and contingency scenarios.

• First 72-hour checklist – rapid introduction of the new PM to priorities, dependencies, and key contacts.

These practices demonstrate that handover during a PM turnover is not a cost, but a strategic investment in IT project resilience.

Summary

Lack of formal handover in IT projects is one of the most underestimated project risks. It can lead to problem escalation, pressure on the team, and subsequent PM rotations, which in practice increases costs and extends project delivery time.

Implementing systematic knowledge transfer procedures during a PM transition in an IT project is not only a project management best practice – it is a strategic safeguard for IT projects that minimizes chaos and increases the chances of success.
