1. Poor Communication with Stakeholders

The Mistake: Many new project managers underestimate the importance of clear and regular communication with stakeholders. This can result in misunderstandings, missed deadlines, and loss of trust.

How to Avoid It:

  • Establish a communication plan that outlines how and when updates will be shared.
  • Use project management tools (such as Trello, Asana, or Microsoft Teams) to keep everyone informed.
  • Hold regular check-ins with your team and stakeholders to ensure alignment on project goals.

The Higher Certificate in Project Management at MANCOSA includes modules on stakeholder management and project communication, helping students develop effective communication strategies.

2. Failing to Define Clear Project Goals and Scope

The Mistake: Many new project managers rush into execution without clearly defining the project scope, leading to scope creep – where project requirements keep expanding, causing delays and budget overruns.

How to Avoid It:

  • Start every project with a clearly defined scope statement outlining deliverables, deadlines, and responsibilities.
  • Use the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) to set realistic goals.
  • Get written approval from stakeholders before making changes to the project scope.

MANCOSA’s Higher Certificate in Project Management covers essential topics such as project scope management and planning, ensuring students are equipped to set and manage project goals effectively.

3. Ineffective Risk Management

The Mistake: New project managers often fail to identify potential risks early, leaving them unprepared when challenges arise.

How to Avoid It:

  • Conduct a risk assessment at the beginning of every project to identify potential obstacles.
  • Develop a risk response plan outlining how to handle potential issues.
  • Regularly review and update risk management strategies as the project progresses.

Through MANCOSA’s Project Risk Management module, students learn how to assess and mitigate project risks, ensuring better decision-making in real-world scenarios.

4. Poor Time and Resource Management

The Mistake: Many new project managers struggle with balancing time, resources, and workloads. This can lead to missed deadlines, overworked teams, and inefficient project execution.

How to Avoid It:

  • Use project scheduling tools like Gantt charts to plan timelines effectively.
  • Allocate resources based on team strengths and availability to prevent burnout.
  • Regularly track progress and adjust schedules to meet deadlines.

MANCOSA’s Project Schedule, Cost and Budget Control module provides students with skills to manage time and resources efficiently, helping them deliver successful projects.

5. Neglecting Team Motivation and Engagement

The Mistake: New project managers often focus only on project tasks and forget about team morale. Unmotivated team members can lead to decreased productivity and engagement.

How to Avoid It:

  • Recognise team efforts and celebrate small wins to boost morale.
  • Encourage open communication and listen to team concerns.
  • Provide growth opportunities and professional development for team members.

MANCOSA’s Fundamentals of Project Management module includes insights on leadership and team dynamics, ensuring students learn how to manage and motivate teams effectively.
