Prioritizing schedule adherence over the quality of deliverables, ignoring changes in customer requirements to ensure on-time delivery, failing to adjust the project to take account of operational obstacles encountered in the field... Falling into the pitfall of the tunnel effect is the bête noire of project managers. Understanding its mechanisms and consequences is crucial to identifying the warning signs. Knowing how to prevent it helps maintain visibility of project progress and ensure that it remains aligned with set objectives. By adopting appropriate strategies, teams can avoid this harmful effect and increase their chances of success.

Understanding the tunnel effect

What is the tunnel effect?

Tunneling in project management refers to a situation where team members focus excessively on a single task or specific objective, often to the detriment of other aspects of the project. In addition, the project team, stakeholders or managers have little or no clear visibility of the project's progress over an extended period. This lack of communication and transparency can then create uncertainty and anxiety, as stakeholders do not know whether the project is progressing as planned, or whether it is encountering obstacles. 

Neglecting the interdependencies between different phases or teams can significantly undermine the overall coherence of the project and the achievement of objectives. Project managers and their teams therefore need to recognize the early signs of this effect, and adopt strategies to maintain a global perspective throughout the project lifecycle.

The consequences of the tunnel effect

The risks associated with the tunnel effect in project management are diverse, and can have a significant impact on overall project success. Here are a few potential consequences:

• Misallocation of resources: when the team focuses excessively on one specific aspect of the project, it risks neglecting the balanced distribution of resources such as time, finance and human skills. This can lead to over-utilization of resources on certain aspects of the project, while other parts of the project could suffer from under-investment, subsequently resulting in imbalances detrimental to overall efficiency.
  
  
• A drop in the quality of the work produced: excessive concentration on a single aspect of the project can compromise the quality of the work produced. The team may lack the time or resources to carry out in-depth analysis or adequate quality testing on all project components. This can lead to errors, defects or shortcomings that compromise end-customer satisfaction.
  
  
• De-motivation within the team: working in an environment where attention is constantly focused on a single objective can lead to frustration and de-motivation among team members. Individuals may feel neglected or ignored if their contribution to other aspects of the project is not recognized or valued. 

The causes of the tunnel effect

The underlying causes of the tunnel effect in project management are often multifactorial, and can stem from a variety of organizational and behavioral dynamics. Two of the main causes to consider include :

Lack of effective communication

Ineffective communication within the project team is one of the main causes of the tunnel effect. When communication channels are unclear, or when certain information is not adequately shared, team members may not have a complete, shared vision of the project. This can lead to misunderstandings, misinterpretations and uneven distribution of effort.

For example, if departments or teams fail to communicate regularly about their progress, challenges and needs, this can lead to an excessive focus on those parts of the project where communication is more fluid. As a result, less visible or less publicized aspects of the project may be neglected, compromising the overall project objective.

A poorly defined working method

An unclear or ill-defined way of working can also contribute to the tunnel effect. When project milestones are not clearly defined, or when processes for assessing and validating progress are vague, team members may be tempted to focus only on those aspects of the project that seem most obvious or urgent. This can lead to an over-prioritization of certain tasks or phases of the project, to the detriment of other equally important stages.

For example, if the validation criteria for moving from one phase to another are not clearly defined, the team could find itself investing a great deal of time and resources in a preliminary phase without being adequately prepared for the subsequent stages. This creates an imbalance in the progress of the project, and can even lead to delays or failures later on when the interdependencies between phases become evident.

Avoiding the tunnel effect

To avoid the tunnel effect in project management, it is important to implement several complementary practices and strategies:

Adopt precise communication

• Define a clear project vision from the outset and communicate it to the whole team. Ensure that each member understands not only the specific objectives, but also how these contribute to the overall success of the project.
• Encourage open and transparent communication to foster collaboration and mutual understanding of challenges and priorities.
  

Risk analysis 

• Conduct a continuous risk analysis throughout the project. Identify areas where excessive concentration could occur and assess potential impacts on the overall project.
• Implement proactive risk management strategies to anticipate problems and minimize their negative effects. This includes planning corrective measures and implementing contingency plans.
  

Strategic planning 

• Develop a detailed plan that breaks down the project into phases, milestones and key milestones. Ensure that each phase is aligned with the overall objectives, and that interdependencies between different parts of the project are well managed.
• Organize regular project reviews to assess progress against objectives. Use these reviews to adjust priorities, reallocate resources if necessary, and make informed decisions about the future direction of the project.
  

Focus on collaboration  

• Create an environment where collaboration is valued and encouraged. Foster interactions between teams and departments to facilitate a holistic understanding of challenges and opportunities.
• Establish clear roles and responsibilities for each team member. Ensure that everyone understands their role in achieving project objectives and managing associated risks.
  

Developing skills 

• Investing in the team's professional development in project management, communication and problem-solving. Offer training adapted to the specific needs of the project and encourage continuous learning.
• Strengthen leadership and decision-making skills within the team to improve the ability to navigate through potential challenges and maintain team cohesion throughout the project.

The tunnel effect in project management can be a formidable obstacle, but it is far from insurmountable. By adopting a proactive approach based on communication, transparency and rigorous process management, project managers can minimize the risks associated with this effect and lead their teams to success. Integrating these practices into a project management strategy not only avoids the pitfalls of the tunnel effect, but also optimizes overall performance and stakeholder satisfaction.
