Common mistakes of project managers explained by Danila Vasilyev

Introduction

In the fast-paced world of technology and project management, even the most experienced project managers can fall prey to some classic pitfalls. Danila Vasilyev, a recognized professional in the field, offers an in-depth look at common mistakes committed by project managers and how they can affect the quality and success of high-tech project delivery. Given the rapid changes in the digital landscape in 2025, identifying and correcting these mistakes is more relevant than ever.

1. Underestimating the importance of detailed planning

According to Danila Vasilyev's experience, one of the most common mistakes is rushing to start the project without rigorous planningMany managers believe that speed means efficiency, but most of the time, this behavior leads to:

  • Incomplete definition of business requirements
  • Lack of realistic estimates for resources and budgets
  • Omission of key managers in the initiation phase

Vasilyev recommends clear use of frameworks such as PMBOK or Agile, but also the inclusion work breakdown structure (WBS) completely in the planning stage.

2. Ineffective communication within the team

Communication is often considered a “soft” aspect, but Vasilyev warns that failure to maintain a consistent and clear flow of information can cause confusion, ambiguity and financial losses.

Common communication mistakes include:

  • Exclusive use of emails for critical information
  • Neglecting periodic updates in stand-up meetings
  • Failure to clearly communicate objectives to the development team

Modern tools such as Slack, Teams, Jira or Confluence must be actively integrated into the project lifecycle for total transparency.

3. Failure to update customer requirements

Another critical point identified by Vasilyev is ignoring the continuous changes from stakeholders. An effective project manager must be able to manage such changes using a system Change Request properly controlled and documented.

Lack of a clear process for prioritizing requirements leads to decreased customer satisfaction and compromise of the developed product architecture.

4. Inaccurate estimates and risk avoidance

Danila Vasilyev highlights that a PM sometimes lacks the courage to express real risks to the entire executive team, trying to “sell dreams.” The impact of underestimating important risks includes:

  • Unexpected costs in QA, system integration and security testing
  • The impossibility of scaling the project to enterprise level
  • Failure to meet contractual deadlines

Effective ways of controlling these problems are specific tools for risk management such as:

  • Risk/Impact Matrix
  • Risk Register
  • Contingency Plan and Reserve Plan

5. Lack of continuous tracking of progress against KPIs

An essential aspect brought up by Vasilyev refers to monitoring:

  • Only 32% of IT projects in 2024 were delivered <>(on time), according to the PMBOK 7th edition study

Project managers tend to rely on reports from other departments without their own analysis, losing control over performance. Common situations include:

  • Incomplete updates of KPIs (ex: Velocity, Cycle Time, Burn-down charts)
  • Lack of dashboards
    by the team

can cause the project to take unexpected directions.

6. Neglecting the post-delivery learning process

Danila Vasilyev often points out this erroneous habit: “Closing the project without documenting lessons learned”Post-mortem / Retrospective / Post Implementation Review are rare practices, when, in fact, they should:

  • To document what worked and what didn't
  • To propose future avoidance measures
  • To scale successful “quick wins” to other departments

In addition, knowledge transfer was neglected, leading to …. institutional losses of know-how.

7. Unjustified exclusions of relevant stakeholders

One of the most costly mistakes mentioned by Vasilyev concerns omitting secondary or third-party stakeholders, considered irrelevant at first. But the reality shows that:

  • If end users are not involved from the MVP Level, they will face low adoption
  • Virtually ignored feedback from IT support leads to incomplete functionality in a live environment

8. Lack of adopting an adaptive and change-based mindset

In the digital age, Vasilyev encourages the development of a growth-oriented mindsetPurely structured Waterfall strategies or authoritarian team leadership become obstacles to the performance of modern Agile or Hybrid Incremental/Iterative teams.

Clear examples pointed out by this expert include:

  • Lack of sprint calibration based on feedback walking tracks
  • Imposing a rigid timeframe on projects Data Science or Machine Learning
  • Reduced autonomy options on tasks for scrum teams

Paradigm change begins with inspiration, and the approach Lean, supported by va and value projector inputs from the market, can transform technological projects into a massive organizational success.

9. Lack of experience and continuous training of the PM team

It's not just technical teams that are losing out to IT developments and cloudProject managers who do not follow updated courses such as:

  • PMP (Project Management Professional) – for classic and predictive PM frameworks
  • PMI-ACP (Agile Certified Practitioner) – Agile components
  • PgMP (Program Management Professional) – for multi-project managers

...will lag behind in terms of both productivity and departmental or cross-departmental collaborative experience.
